Their compact size and abundance of programming ports makes them ideal for integration into any Test Fixture or ATE System. They supports programming of devices by most interfaces including SPI, JTAG, JTAG chain, SCI, I2C (2wire), XMEGA PDI, ATtiny TPI and UART Boot Loader. The fastest possible programming times are guaranteed due to a combination of highly optimised algorithms, local storage of Project Data and high slew rate Line Driver Circuitry. The ISPnano series of programmers represents a scaleable ISP programming solution capable of programming multiple PCBs on a 'PCB Panel'. This is made possible by networking up to 32 x ISPnano programmers to a single PC. All programmers can then be configured to start simultaneously under PC control. 1.1 ISPnano Series III Programmer The ‘ISPnano Series III’ is a state-of-the-art Production ISP Programmer designed for high-speed InSystem Programming (ISP) of FLASH Microcontrollers and Serial Memory devices. Its compact size and abundance of programming ports makes it ideal for integration into any Test Fixture or ATE System. It supports programming of devices by most interfaces including SPI, JTAG, JTAG chain, SCI, I2C (2-wire) and UART Boot Loader. The fastest possible programming times are guaranteed due to a combination of highly optimised algorithms, local storage of Project Data and high slew rate Line Driver Circuitry. The ‘ISPnano Series III’ is capable of operating in 'Standalone Mode' where any one of 64 independent 'Programming Projects' can be executed via a remote command. The programmer also features a ‘4-wire TTL Remote Control interface’ making it ideal for interfacing to any ATE or In-Circuit Tester (ICT). A special 'Start Signal' can be used to detect when a Test Fixture lid has been closed and thereby automatically start a programming operation. The ‘ISPnano Series III’ is a scaleable ISP programming solution capable of programming multiple PCBs on a 'PCB Panel'. This is made possible by networking up to 32 x ISPnano programmers to a single PC. All programmers can then be configured to start simultaneously under PC control. th ISPnano Series Programmer - User Manual – V1.11 – 12 May 2011 1 1.2 ISPnano Series III ATE Programmer The ‘ISPnano Series III ATE’ is a state-of-the-art Production ISP Programmer designed for highspeed In-System Programming (ISP) of FLASH Microcontrollers and Serial Memory devices. It has been specially developed to allow simple integration with ATE Systems and In-Circuit Testers (ICTs) used in high-volume production environments. The programmer supports automated relay switching of all Target System signal and power signal lines between an external ATE / ICT system and the internal programmer electronics. This allows the programmer to be completely out-of-circuit during normal ATE / ICT testing operation. A dedicated 'ATE Interface' allows the ATE / ICT to control the operation of the programmer in 'Standalone Mode'. The compact size and abundance of programming ports makes the ‘ISPnano Series III ATE’ ideal for integration into any Test Fixture or ATE System. It supports programming of devices by most interfaces including SPI, JTAG, JTAG chain, SCI, I2C (2-wire), XMEGA 2-wire PDI, ATtiny HV (+12V Vpp), ATtiny TPI and UART Boot Loader. The fastest possible programming times are guaranteed due to a combination of highly optimised algorithms, local storage of Project Data and high slew rate Line Driver Circuitry. The ‘ISPnano Series III ATE’ is capable of operating in 'Standalone Mode' where any one of 64 independent 'Programming Projects' can be executed via a remote command. Please note: The ‘ISPnano Series III ATE’ programmer features a standard ‘ISPnano Series III’ programming module and a ‘relay switching module’ integrated into a single enclosure. The ‘ATE’ version will run exactly the same projects as the standard version with the exception that the ‘EXT-VCC’ supply is used to power / control the relay coils. 2 th ISPnano Series Programmer - User Manual – V1.11 – 12 May 2011 1.3 ISPnano MUX2 / MUX4 / MUX8 - Multiplexed Programmers The ‘ISPnano-MUX’ family of ISP programming systems have been specially developed for medium to high-volume production programming applications where there is a requirement to program multiple devices mounted on a ‘PCB Panel’. The ‘ISPnano-MUX’ programmers use a single integrated 'ISPnano Series 3’ programmer which is then multiplexed sequentially to each UUT (Unit Under Test) in turn on the PCB panel. This allows the system to sequentially program up to 8 individual UUTs, one after the other. Main Features… • Available as 2 / 4 or 8 channel multiplexed programming system • Supports sequential programming of 2 / 4 or 8 UUTs (depending on programmer model) • A single 'ISPnano Series 3' programmer is multiplexed sequentially to 2 /4 / 8 individual Target Boards (UUTs) • All programming signals are multiplexed to each UUT using high-quality analogue switches • All programming signals are fully ESD and over-voltage protected • All passive / power signals (Target VCC, Target Vpp and EXT-VCC power signals) are switched via individual high-quality relays to each UUT • Power is always switched off to the target UUT before switching to the next UUT thus providing very long relay contact life • Each programming channel features its own interchangeable 'I/O Connector Module' with relays and any custom target connectors • Status indicators include - current channel being programmed and PASS / BUSY / FAIL • Controllable via a PC using the Equinox EDS, ConsoleEDS or ISP-PRO software utilities • Channel multiplexer control can be controlled either via the PC or a remote system ISPnano-MUX Programmer range…. There are currently three programmers in the ‘ISPnano-MUX’ family as detailed in the table below…. Programmer version: ISPnano-MUX2 ISPnano-MUX4 ISPnano-MUX8 Number of multiplexed programming channels 2 4 8 No. of programming channels (RS485 networked) up to 64 channels up to 128 channels up to 256 channels Intended use / application Programming 2 devices on the same PCB e.g. microcontroller + memory device Programming 4 x PCBs on a multi-PCB panel Programming 8 x PCBs on a multi-PCB panel Q2 2011 Q2 2011 Available now Availability th ISPnano Series Programmer - User Manual – V1.11 – 12 May 2011 3 The picture below shows the ‘ISPnano-MUX8’ programmer… Sequential multiplexing… The sequential multiplexing approach supports programming of only one UUT at a time which means that the programming time for a panel of e.g. 2 / 4 / 8 PCBs which will be significantly longer than if an individual programmer was used for each channel. However, for many programming applications, the programming time is very short anyway or is not the most important factor in the system, so this multiplexed approach would work very well. Multiplexing of programming signals… The programming signals for each programming channel are multiplexed using high-quality analogue switches to each UUT in turn. The power signals (TVCC, VPP and EXT-VCC) are all individually switched to each UUT using relays. This approach allows the power to each UUT to be individually controlled and measured and means that only a single UUT is then powered on at any point in time making it possible to detect short circuits and other faults for an individual UUT. Operating the programmer in ‘Standalone Mode’…. The ISPnano-MUX programmers are capable of operating in 'Standalone Mode' where any one of 64 independent 'Programming Projects' can be executed via a remote command. The programmer also features a 4-wire TTL Remote Control interface making it ideal for interfacing to any ATE or InCircuit Tester (ICT). A special 'Start Signal' can be used to detect when a Test Fixture lid has been closed and thereby automatically start a programming operation. 4 th ISPnano Series Programmer - User Manual – V1.11 – 12 May 2011 1.4 ISPnano Programmer Module - Main Features The main features of the ‘ISPnano Programming Module’ are detailed in this section.

An overview of the available control mechanisms is given below. Standalone Operation (Keypad) The programmer can be operated using the ‘START’ button without being connected to a PC or other control system. This will execute the first project found in the programmer memory. Remote System Control (4-wire) This indicates that the programmer can be controlled from a remote electrical system e.g. In Circuit Tester (ICT) or PLC using a 4-wire TTL protocol (START, ACTIVE, PASS, FAIL). This method only supports execution of ‘Standalone Programming Projects’ which have been previously uploaded to the programmer. Test Fixture - Jig Switch Control (1-wire) A switch on the Test Fixture lid can be used to automatically start a ‘Standalone Programming Project’ in the programmer. ASCII Text Mode Control This indicates that the programmer can be controlled using a simple 'ASCII Serial Communications Protocol'. This is ideal for applications where a Remote System wishes to control the programmer using a serial communications link e.g. RS-232. This method only supports execution of ‘Standalone Programming Projects’ which have been previously uploaded to the programmer. ISP-PRO Software This software suite is capable of controlling up to 32 x Equinox Production ISP programmers on an RS-485 network at the same time. All programming operations are controlled via 'Programming Scripts' and 'Programming Projects' which have been created using EQTools. The application minimises user intervention during programming and logs all programming operations to an Interface Database. Labview Control (PC) This allows an Equinox programmer to be controlled by a remote Labview Application. The Labview application can launch 'Programming Scripts' and read/write unique data such as serial numbers and calibration data. Remote Application Control (PC) This allows an Equinox programmer to be controlled by a Remote Application written in e.g. Visual Basic, C++ etc. The Remote Application can launch 'Programming Scripts' and read/write unique data such as serial numbers and calibration data. ConsoleEDS This is a powerful utility which allows any Equinox ISP Programmer to be controlled from a PC application by executing simple command-line instructions. This method of control is ideal for interfacing the programmer to any Windows application including Visual Basic, Labview etc. th ISPnano Series Programmer - User Manual – V1.11 – 12 May 2011 27 2.3.3 Software Installation The ISPnano programmer comes with the software suite called ‘EQTools’ as standard.

EDS allows you to read/write the target device FLASH / EEPROM / FUSE / LOCK bits interactively under PC control without uploading a ‘Programming Project’ to the programmer. 2.5 2 Standalone Keypad Mode None S In this mode, the programmer is not connected to a PC and can program a single ‘Programming Project’ into the Target Device when the key is pressed. (A valid project must have been previously uploaded to the programmer using EQTools – Upload Wizard.) 2.6 3 Standalone ASCII Text Communications Control Any Terminal S This protocol can be used to control an Emulation Equinox programmer from a Remote Software Application or Remote System using a simple set of ASCII serial commands. This protocol is ideal for controlling Equinox programmers from any Remote System which features an RS-232 serial port and which can operate at a fixed baud rate of 38,400. 2.7 4 Standalone 4-Wire TTL Control None S The programmer can be controlled using a 4-wire TTL signalling protocol as shown in the diagram below. This control method is ideal for interfacing the programmer InCircuit Testers (ICT’s) or other production equipment which does not have an RS-232 port. 2.8 5 Target System auto-detect mode None S The programmer is capable of automatically 2.9 detecting when a Target System is connected to / disconnected from the programmer. This can be used to trigger the execution of a Programming Project in Standalone Mode. th ISPnano Series Programmer - User Manual – V1.11 – 12 May 2011 29 6 Script Mode EQTools – Script Debugger or ISP-PRO U In this mode, the programmer is controlled 2.10 from a ‘Programming Script’ running within either the EQTools or ISP-PRO applications on a PC. 7 ConsoleEDS ConsoleEDS U In this mode, the programmer is controlled via the ConsoleEDS utility which allows control via simple Command Line commands and arguments 2.11 See App Note AN111 Key S – feature available as standard U – a license upgrade must be purchased from Equinox to enable this feature. 30 th ISPnano Series Programmer - User Manual – V1.11 – 12 May 2011 2.5 Programmer Status LEDs The current status of the programmer is displayed on the programmer Status LED’s as detailed in the table below.

See programmer LCD for diagnostics Programmer will automatically switch off target power if it is controlling power. Programming operation was successful. • FAIL • • • PASS • Status LED key: Please note: • There are also two special modes called ‘Waiting Target Connection’ or ‘Waiting Target Disconnection’ where the yellow BUSY LED will FLASH. • These modes are enabled when ‘Target Connection Sense’ is enabled in the Programming Project. th ISPnano Series Programmer - User Manual – V1.11 – 12 May 2011 31 2.6 ASCII Text Communications Mode 2.6.1 Overview The ‘ASCII Text Control’ communications protocol or ‘ATC’ is designed as a simple way for a Remote Test System to control the basic programming operations of an Equinox programmer via an RS-232 serial link. It is an ‘ASCII’ protocol with simple commands to initiate programming of preloaded ‘Standalone Programming Projects’ which are stored in the on-board ‘FLASH Memory Store’ of the programmer. The protocol supports up to 64 independent Programming Projects per programmer, but is limited to one programmer. Implementation of this protocol is straightforward due to the limited number of commands and restricted functionality. As this is an ASCII protocol, it can be quickly evaluated using any Terminal Emulation Software Utility such as Hyperterminal. 2.6.2 Limitations of this protocol This protocol has been designed as a simple method to allow a Remote Application such as an InCircuit Tester to control the basic operations of an Equinox programmer. The programmer only supports the programming of entire ‘Programming Projects’ which are already uploaded to the programmer on-board FLASH memory. This protocol does not support writing / reading of individual bytes or blocks of data to / from a Target Device. The limitations of this protocol are as follows: 1. The protocol only supports programming of Programming Projects which are pre-loaded into the Programmer on-board FLASH Memory Store. 2. The protocol does not support writing / reading of individual bytes or blocks of data to / from a Target Device. 3. The protocol does not support uploading of ‘Standalone Programming Projects’ to the programmer. This must be performed using the ‘EQTools – Project Upload Wizard’. 4. Only very limited diagnostics are available using this protocol ie. FAIL + Error Number. 2.6.3 Further Information A full description of this protocol can be found in the following Application Note: ‘AN110 - ASCII Text Control (ATC) Protocol for Remote Control of Equinox Programmers’. 32 th ISPnano Series Programmer - User Manual – V1.11 – 12 May 2011 2.7 Standalone Remote I/O Programmer Control 2.7.1 Overview The ISPnano programmer can be controlled using a simple 4-wire Remote I/O (TTL) signalling protocol as shown in the diagram below. This control method is ideal for interfacing the programmer to In-Circuit Testers (ICT’s) or other production equipment which does not have an RS-232 port. Fig. 2.8.1 Remote System Control of Programmer START Equinox PPM3 Programming Module ACTIVE Remote System OK FAIL GROUND The Remote System simply asserts the programmer signal to initiate the execution of a ‘Programming Project’. The programmer will then assert the signal to indicate that it has commenced programming. At the end of the Programming operation the programmer asserts either the or signal depending on the outcome. The Remote System must then de-assert the signal to allow the programmer to reset ready to program the next device. Please refer to section 2.8.3 for an example of the Remote I/O control signal waveforms for a typical programming iteration. th ISPnano Series Programmer - User Manual – V1.11 – 12 May 2011 33 2.7.2 TTL 4-Wire Remote Control – Signal Connections The Remote System connects to the programmer via the ‘Remote Control Port’ which is the 14-way IDC connector.

A load sensing technique is used to detect the presence of the UUT. This method of UUT detection can be used to trigger a ‘Standalone Programming Project’ or even a sequence of chained projects to start. The typical sequence of events is as follows: • Programmer waits for UUT to be connected (flashing BUSY LED) • Operator connects UUT to programmer • Programmer detects connection of UUT • Programmer automatically executes a sequence of Standalone Programming Projects • At the end of the programming sequence, the programmer will FLASH either the PASS or FAIL LED • Programmer then goes into ‘Target Disconnection Sensing’ mode (flashing BUSY LED) • Operator removes the UUT • Programmer resets itself ready for the next UUT Please see Application Note – AN113 for further instructions on how to set up your programmer to operate in this mode. 2.9 Script Mode (ISP-PRO) ‘Script Mode’ is designed for production users who require logging of all programmer operations to a database. This mode utilises the Equinox ISP-PRO software which allows execution of Programming Scripts. It is possible to write scripts to program unique data such as serial numbers, calibration data etc. It is also possible to control the programmer from a Remote Application written in eg. Labview, Visual Basic, C++ etc. In order to use ‘Script Mode’ with your programmer, it is necessary to purchase the relevant license upgrade for ISP-PRO.Please see the Equinox Website for further details. 36 th ISPnano Series Programmer - User Manual – V1.11 – 12 May 2011 2.10 ConsoleEDS – Command Line control ConsoleEDS is a powerful software utility which allows any Equinox ISP Programmer to be controlled from a custom Remote Application running under Windows. The main features of ConsoleEDS are: • Allows an Equinox ISP Programmer to be remote controlled via simple Command Line commands. • Suitable for interfacing to any application which executes under Windows • Simple Command Line interface makes even complex programming operations simple to implement • Supports writing of a block of data from a file to the FLASH or EEPROM of a Target Chip • Supports reading of a block of data from the FLASH or EEPROM of the Target Chip to a file on the PC hard disk • Supports uploading of pre-compiled standalone ‘Programming Projects’ to a target programmer without requiring EQTools or the Project Upload Wizard. • Supports running of a specified ‘Standalone Programming Project’ which has already been uploaded into the programmer ‘FLASH Memory Store’ • Supports programming of the ‘Configuration Fuses’ of the Target Chip • Supports programming of the ‘Security Fuses’ of the Target Chip • Supports automatic generation of and programming of unique information such as serial numbers and calibration data • Supports reading / writing of Atmel AVR on-chip Oscillator Calibration Byte Please note: Many of the above features are only accessible when using ‘ConsoleEDS PRO’.

The programmers are daisy-chained together on an RS485 network using special ‘5-pin Molex RS485 Cables’ which connect to the ‘RS485 In / Out’ connectors on the ISPnano programmer. The diagram below shows a typical RS485 programmer network with 2 x ISPnano programmers daisy-chained together. The RS485 converter should be placed as close to the PC as possible so as to minimise the length of the RS232 cable. The cable from the RS485 Converter to the first ISPnano programmer must be terminated using the ‘RS485 FCC68 to 5-pin Molex Converter Module’ as the ISPnano uses a smaller 5-pin Molex connector. 3.5.2 Equipment required To operate the programmers in multi-channel RS485 mode, you will need the following equipment: • 1 x PC with spare 9-way COM Port • 1 x Equinox ‘RS232 to RS485 Converter’ (Order code: RS485-C2) • 1 x ‘RS485 FCC68 to 5-pin Molex Converter Module’ (Converts RJ11 to 5-pin Molex ISPnano RS485 connector) • 1 x RJ11 RS485 Flat Cable (pin-out crossed) • n x ‘5-pin Molex RS485 Cable’ (for connecting between ISPnano programmers – where n is the number of programmers) 48 th ISPnano Series Programmer - User Manual – V1.11 – 12 May 2011 3.5.3 Instructions To set up a multi-channel RS485 programmer network, please follow the instructions detailed below… • Place the ‘RS485 Converter’ as close to the PC COM port as possible. • Connect the 9-way RS232 cable between the ‘RS485 Converter’ RS232 port and a spare PC COM Port. • Connect an ‘RS485 Cable’ flat cable (must be an ‘crossed cable’) from either of the ‘RS485 Connectors’ on the Converter to the ‘RS485 FCC68 to 5-pin Molex Converter Module’ • Connect a ‘5-pin Molex RS485 Cable’ to the ‘RS485 In’ connector on the first programmer in the series. • Connect a ‘5-pin Molex RS485 Cable’ from the ‘RS485 Out’ connector on the first programmer to the ‘RS485 In’ connector on the second programmer in the chain. • Connect a ‘5-pin Molex RS485 Cable’ from the ‘RS485 Out’ connector of the second programmer to the connector of the third programmer…..and so on until you reach the last programmer in the chain. Important notes: • The RS232 cable between the ‘RS485 Converter’ and the PC COM Port should be kept as short as possible i.e. no longer than 2m. • The RS485 Converter should be placed as close to the PC COM port as possible. • An RS485 terminator is NOT required on the last programmer. • The ‘RS485 In’ or ‘RS485 Out’ connectors are connected in parallel inside the programmer so it does not matter whether the ‘In’ or ‘Out’ connector is used. • Each programmer on the RS485 network must have a unique ‘Node Address’. The address is set by connecting to either RS232 port and then using the ‘Set Node Address’ utility in EQTools. • This mode of operation requires either the ISP-PRO or ConsoleEDS software utilities to be running on the PC 3.5.4 RS485 FCC68 to 5-pin Molex Converter Module The cable from the RS485 Converter to the first ISPnano programmer ‘RS485 In’ connector must be terminated using the ‘RS485 FCC68 to 5-pin Molex Converter Module’ as the ISPnano uses a smaller 5-pin Molex connector. The ‘Converter Module’ is a small circuit board which converts the RJ11 connector from the RS485 Converter to the miniature 5-pin Molex connector used for RS485 connections on the ISPnano programmer. The flat cable from the RS485 Converter plugs in one end. A ‘5-pin Molex RS485 Cable’ plugs in the other end and then connects to the first ISPnano programmer in the chain. th ISPnano Series Programmer - User Manual – V1.11 – 12 May 2011 49 3.6 Detecting attached programmers 3.6.1 Overview An ISPnano programmer can communicate to a controlling PC via RS232, RS485 or USB. It is factory configured to have the ‘Communications Node Address’ set to ‘0’. If you know that the attached ISPnano programmer is configured as ‘Address 0’, then you simply need to make sure that the ‘Communications Address’ in EQTools is set to ‘0’ and then EQTools should be able to communicate with the programmer. This is the standard setting for EQTools and an ISPnano programmer. If the attached programmer has been configured with an address which in not ‘0’ or you have multiple programmers attached on the RS485 bus, then the simplest way to find out which programmers are attached is to use the ‘Detect Programmer(s)’ utility in EQTools. 3.6.2 Using the ‘Detect Programmer(s)’ utility The instructions below detail how to detect one or more programmers which are connected to the PC. Instructions • Launch EQTools • Select • EQTools will now scan addresses 0 to 31 for attached programmers. • 50 A list of the attached programmers which have been detected will then be displayed. In the example below 12 x ISPnano programmers have been detected with ‘Node Addresses’ ranging from 0 to 11. th ISPnano Series Programmer - User Manual – V1.11 – 12 May 2011 • • To set EQTools to communicate with a particular programmer, simply click the radio button next to the desired programmer in the list and then click EQTools will now be set up to communicate with the attached programmer at the specified address. 3.6.3 Resolving Programmer Detection issues If no programmers are detected, please check the following: • The serial cable is connected between the PC COM port and the programmer or the RS485 Converter. • All programmers are powered up. • All programmers have a unique ‘Node Address’. • The ‘RS485 Converter’ (if used) is powered on. If multiple programmers are detected but some are not detected, please check the following: • The RS485 cable is connected between the last detected programmer and the first nondetected programmer. • Try swapping the RS485 cable for a known working cable just in case the cable is faulty. • Make sure each programmer has a unique ‘Node Address’. If more than one programmer has the same address then this may cause ‘Communications Errors’. th ISPnano Series Programmer - User Manual – V1.11 – 12 May 2011 51 3.7 Setting the programmer ‘Communications Node Address’ It is possible to have up to 32 x ISPnano programmers networked together on an RS485 bus. Each programmer must have a unique ‘Communications Node Address’ so that the PC knows which programmer it is communicating with. This address must be in the range of 0 to 31. The address is set by default to address ‘0’ (zero). On the ISPnano programmer, the ‘Communications Node Address’ is stored in a location in EEPROM and is therefore permanently remembered by the programmer even if the programmer is power cycled. It is possible to set the ‘Communications Node Address’ to any address between 0 and 31 using the ‘Programmer and Scripting Setup’ screen in EQTools. Setting of the address can only be done when connected to the programmer via RS232. To set ‘Communications Node Address’ : • Select either the ‘RS232-1’ or ‘RS232-2’ serial ports on the programmer. • Connect a serial cable from either of these serial ports to a spare PC COM port on your PC. • Launch EQTools • Select • The following screen is displayed… • • • 52 Select either the COM port to which the programmer is connected e.g. COM1 Click the button
The following screen will be displayed: th ISPnano Series Programmer - User Manual – V1.11 – 12 May 2011 Change the ‘New Address’ field to be the address you want to give the attached programmer e.g. address 5 • Click
The programmer should now confirm that the correct address has been stored. • • • Click

The ISPnano programmer is not just a programmer. It also features two very accurate user-programmable power supplies which can be used to power the Target System (UUT). The ISPnano programmer family features the following internal power supplies…. # Pow er Suppl y Voltage V ol ta g e M a x C u r r e n t ISPnano range accuracy current monitor / limit Output Pin (V DC) (mA) 1 Programmer Controlled Target Vcc (TVCC) Power Supply 1.8 – 5.0 +/- 1% 480 Yes 5% accuracy TVCC 2 Programmer Controlled Target Vpp (TVPP) Power Supply 6.5 – 13.5 +/- 3% 100 No TVPP 3 Programmer controlled EXTERNAL VCC Switch 1.2 – 30.0 N/A 1000 No EXT-VCC The illustration below shows how these power supplies are implemented…. th ISPnano Series Programmer - User Manual – V1.11 – 12 May 2011 57 4.2 Typical applications of each power supply The table below gives an overview of the typical applications of the different ISPnano programmer power supplies.…. # Power Supply 1 Programmer Controlled Target Vcc (TVCC) Power Supply Voltage range (V DC) 1.8 – 5.0 Features / typical application of power supply • • • • 2 Programmer Controlled Target Vpp (TVPP) Power Supply 6.5 – 13.5 3 Programmer controlled EXTERNAL VCC Switch 1.2 – 30.0 • • • • • • Used to power the internal ‘Programmer Line Driver Circuitry’ which sets the signal levels for the ‘Programmer Target I/O’ pins. Used to apply controlled power to any Target System (UUT) which can be powered at 1.8 to 5.0V. Can also be used to power up the UUT at a specified voltage for target testing and / or voltage calibration purposes. This power supply also features current / overcurrent monitoring. This power supply should only be used for devices which require a ‘Vpp’ programming voltage to force the device into ‘programming mode’. The voltage is defined by the programming algorithm and is not user-definable. Allows an ‘External power supply’ to be switched under programmer control to a Target System (UUT) Typically used to power a UUT which requires an input voltage of >5.0V Can also be used if the ‘Target I/O Signal Voltage’ needs to be different to the actual ‘Target Voltage’ e.g. an IC is powered at 3.3V but the main UUT circuitry must be powered at e.g. 5.0V. Used to power the relay coils at +12V on the ‘ISPnano Series 3 ATE’ programmer The following sections describe the various power supplies in more detail. 58 th ISPnano Series Programmer - User Manual – V1.11 – 12 May 2011 4.3 ISPnano - Power Supply schematic diagram The diagram below shows an overview of the power supply routing of the ISPnano programmer.

This power supply also features ‘target current monitoring’ so a current-limit can be set up to automatically shut down the power supply in the event of a short-circuit. Power supply features: • User programmable power supply – user can set up both Voltage and Current settings • The power supply can switch 1.2 to 5.0V @ 480mA to the Target System (UUT) • The power supply also generates the ‘Programmer Line Driver Voltage’ which sets the Target I/O signal levels. • The voltage is output on the ‘TVCC’ pin of the programmer • Voltage accuracy: +/- 1% using factory calibrated voltages • Voltage accuracy: +/- 20 mV is possible at user-defined ‘spot calibrated’ voltages • Fast voltage slew-rate on switch-on • Power supply ‘Voltage measurement’ and ‘Target Voltage validation’ (checks that target voltage is within pre-set limits) • User-definable ‘voltage stabilisation’ settings before / after target switch on • Target Voltage can also be measured if the programmer is not supplying power • Power supply by source up to 2 Amps continuously (before going into current limit) allowing it to charge up the ‘target system capacitance’ at high speed • Target current monitoring with over-current detection at switch on • User-definable current stabilisation settings before / after target switch on 60 th ISPnano Series Programmer - User Manual – V1.11 – 12 May 2011 • Current measurement accuracy +/- 6% 4.5 Programmer controlled ‘Target Vpp (TVPP) Power Supply’ The ‘Programmer controlled Target Vpp Power Supply’ is designed to apply a so-called ‘Programmming voltage’ or ‘Vpp voltage’ to a Target IC in order to force Target IC into programming mode. The ICs which require this ‘Vpp voltage’ do not require much current, so this power supply is only rated at 100mA maximum current. Power supply features: • The Vpp voltage is used to force certain ICs into ‘programming mode’ • The Vpp voltage is automatically set up by the selected device algorithm (not user-adjustable) • The programmer can switch 6.5 to 13.5 V @ 100 mA to the Target System (UUT) • Voltage accuracy: +/- 3% using factory calibrated voltages Device algorithms which require this Vpp voltage include: • Atmel - ATtiny TPI interface – High-Voltage Mode (+12V Vpp) • Atmel – ATtiny 4-wire interface – High-Voltage Mode (+12V Vpp) • TI – MSP430 – JTAG mode – Vpp required to blow the ‘Security fuse’ (+13.0V Vpp) Warning! As the programmer is capable of applying a voltage higher than the normal ‘Target Vcc’ voltage, this higher voltage could cause damage to the Target Board circuitry. Please ensure that the Target Board has been designed to withstand the VPP voltage being applied during programming. th ISPnano Series Programmer - User Manual – V1.11 – 12 May 2011 61 4.6 External VCC – programmer controlled switch The ISPnano programmer features a special ‘External VCC Switch’ circuit which allows an ‘External Voltage (V_EXT)’ in the range of 1.6V – 24V to be switched through the programmer to the Target System under project control. This feature is useful when the Target System features a ‘Voltage Regulator Circuit’ which needs to be powered from a higher voltage than +5V. In order to power many Target Systems, it is necessary to apply a voltage of eg. 7 – 24V to the input of the Target System regulator circuit. Power supply features: • Allows an ‘External power supply’ to be switched under programmer control to a Target System (UUT) • Any voltage between 1.2 and 30V can be switched via the ‘External VCC Switch’ circuit. • The ‘External VCC Switch’ circuit is rated at 1 Amp. • Internal self-resetting fuse for protection against short-circuit conditions • Both the input and output ‘External Voltage (V_EXT)’ can measured by the programmer The diagram below shows a typical example where an external power supply is switched to the Target System (UUT) through the programmer.

Typical applications: • Used to control power to a Target System (UUT) which requires an input voltage of > 5.0V. This is typical of many designs where the power supply / regulator circuit on a Target System may require e.g. 9 – 24V which is then regulated down to eg. 3.3V or 5.0V • Used on the ‘ISPnano Series III (ATE)’ programmer to switch +12V power to the relay coils th ISPnano Series Programmer - User Manual – V1.11 – 12 May 2011 63 4.7 Programmer controlled Target Discharge Circuit The ISPnano programmer features a programmer controlled ‘Target Discharge Circuit’ which can be used to automatically discharge any residual charge stored on the Target System (UUT) after the target power has been switched off. This feature can be fundamental in preventing ESD damage to both the UUT and programmer if a UUT is removed from a Programming Fixture while it still has residual charge on it. As soon as the target power supply has been switched off, the programmer automatically switches a resistive load across the Target System (UUT) which discharges any energy stored in reservoir capacitors on the UUT. The programmer constantly monitors the ‘Target Voltage’ on the TVCC pin until the voltage has decayed to a specified voltage e.g.
