Functional description 7.1 ARM Cortex-M0 processor The ARM Cortex-M0 is a general purpose, 32-bit microprocessor, which offers high performance and very low power consumption. 7.2 On-chip flash program memory The LPC1102 contains 32 kB of on-chip flash memory. Remark: The LPC1102 supports In-Application Programming (IAP) and In-System Programming (ISP). For ISP, since there is no dedicated ISP entry pin, user code is required to invoke ISP functionality. Unprogrammed parts will automatically boot into ISP mode. 7.3 On-chip SRAM The LPC1102 contains 8 kB on-chip static RAM memory. 7.4 Memory map The LPC1102 incorporates several distinct memory regions, shown in the following figures. Figure 3 shows the overall map of the entire address space from the user program viewpoint following reset. The interrupt vector area supports address remapping. The AHB peripheral area is 2 megabyte in size, and is divided to allow for up to 128 peripherals. The APB peripheral area is 512 kB in size and is divided to allow for up to 32 peripherals. Each peripheral of either type is allocated 16 kB of space. This allows simplifying the address decoding for each peripheral.

LPC1102 memory map 7.5 Nested Vectored Interrupt Controller (NVIC) The Nested Vectored Interrupt Controller (NVIC) is an integral part of the Cortex-M0. The tight coupling to the CPU allows for low interrupt latency and efficient processing of late arriving interrupts. 7.5.1 Features • Controls system exceptions and peripheral interrupts. • In the LPC1102, the NVIC supports 19 vectored interrupts including up to 6 inputs to the start logic from individual GPIO pins.

Product data sheet Rev. 3 — 18 April 2011 7 of 39 NXP Semiconductors LPC1102 32-bit ARM Cortex-M0 microcontroller • Four programmable interrupt priority levels, with hardware priority level masking. • Software interrupt generation. 7.5.2 Interrupt sources Each peripheral device has one interrupt line connected to the NVIC but may have several interrupt flags. Individual interrupt flags may also represent more than one interrupt source. Any GPIO pin (total of up to 11 pins) regardless of the selected function, can be programmed to generate an interrupt on a level, or rising edge or falling edge, or both. 7.6 IOCONFIG block The IOCONFIG block allows selected pins of the microcontroller to have more than one function. Configuration registers control the multiplexers to allow connection between the pin and the on-chip peripherals. Peripherals should be connected to the appropriate pins prior to being activated and prior to any related interrupt(s) being enabled. Activity of any enabled peripheral function that is not mapped to a related pin should be considered undefined. 7.7 Fast general purpose parallel I/O Device pins that are not connected to a specific peripheral function are controlled by the GPIO registers. Pins may be dynamically configured as inputs or outputs. Multiple outputs can be set or cleared in one write operation. The LPC1102 uses accelerated GPIO functions: • GPIO registers are a dedicated AHB peripheral so that the fastest possible I/O timing can be achieved. • Entire port value can be written in one instruction. Additionally, any GPIO pin (total of 11 pins) providing a digital function can be programmed to generate an interrupt on a level, a rising or falling edge, or both. 7.7.1 Features • Bit level port registers allow a single instruction to set or clear any number of bits in one write operation. • Direction control of individual bits. • All I/O default to inputs with pull-ups enabled after reset. • Pull-up/pull-down resistor configuration can be programmed through the IOCONFIG block for each GPIO pin. 7.8 UART The LPC1102 contains one UART. Support for RS-485/9-bit mode allows both software address detection and automatic address detection using 9-bit mode.

Product data sheet Rev. 3 — 18 April 2011 8 of 39 NXP Semiconductors LPC1102 32-bit ARM Cortex-M0 microcontroller The UART includes a fractional baud rate generator. Standard baud rates such as 115200 Bd can be achieved with any crystal frequency above 2 MHz. 7.8.1 Features • • • • • Maximum UART data bit rate of 3.125 Mbit/s. 16 Byte Receive and Transmit FIFOs. Register locations conform to 16C550 industry standard. Receiver FIFO trigger points at 1 B, 4 B, 8 B, and 14 B. Built-in fractional baud rate generator covering wide range of baud rates without a need for external crystals of particular values. • FIFO control mechanism that enables software flow control implementation. • Support for RS-485/9-bit mode. 7.9 SPI serial I/O controller The LPC1102 contains one SPI controller and fully supports SSP features. The SPI controller is capable of operation on a SSP, 4-wire SSI, or Microwire bus. It can interact with multiple masters and slaves on the bus. Only a single master and a single slave can communicate on the bus during a given data transfer. The SPI supports full duplex transfers, with frames of 4 bits to 16 bits of data flowing from the master to the slave and from the slave to the master. In practice, often only one of these data flows carries meaningful data. Remark: Care must be taken when using the SPI because the SPI clock SCK and the serial wire debug clock SWCLK share the same pin on the WLCSP16 package. Once the SPI is enabled, the serial wire debugger is no longer available. 7.9.1 Features • Maximum SPI speed of 25 Mbit/s (master) or 4.17 Mbit/s (slave) (in SSP mode) • Compatible with Motorola SPI, 4-wire Texas Instruments SSI, and National Semiconductor Microwire buses • • • • Synchronous serial communication Master or slave operation 8-frame FIFOs for both transmit and receive 4-bit to 16-bit frame 7.10 10-bit ADC The LPC1102 contains one ADC. It is a single 10-bit successive approximation ADC with five channels. 7.10.1 Features • 10-bit successive approximation ADC. • Input multiplexing among 5 pins. • Power-down mode.

Burst conversion mode for single or multiple inputs. Optional conversion on transition of input pin or timer match signal. Individual result registers for each ADC channel to reduce interrupt overhead. 7.11 General purpose external event counter/timers The LPC1102 includes two 32-bit counter/timers and two 16-bit counter/timers. The counter/timer is designed to count cycles of the system derived clock. It can optionally generate interrupts or perform other actions at specified timer values, based on four match registers. Each counter/timer also includes one capture input to trap the timer value when an input signal transitions, optionally generating an interrupt. 7.11.1 Features • A 32-bit/16-bit timer/counter with a programmable 32-bit/16-bit prescaler. • Counter or timer operation. • One capture channel that can take a snapshot of the timer value when an input signal transitions. A capture event may also generate an interrupt. • Four match registers per timer that allow: – Continuous operation with optional interrupt generation on match. – Stop timer on match with optional interrupt generation. – Reset timer on match with optional interrupt generation. • Up to four external outputs corresponding to match registers, with the following capabilities: – Set LOW on match. – Set HIGH on match. – Toggle on match. – Do nothing on match. 7.12 System tick timer The ARM Cortex-M0 includes a system tick timer (SYSTICK) that is intended to generate a dedicated SYSTICK exception at a fixed time interval (typically 10 ms). 7.13 Watchdog timer The purpose of the watchdog is to reset the microcontroller within a selectable time period. 7.13.1 Features • Internally resets chip if not periodically reloaded. • Debug mode. • Enabled by software but requires a hardware reset or a watchdog reset/interrupt to be disabled.

(IRC), the Watchdog oscillator, or the main clock. This gives a wide range of potential timing choices of Watchdog operation under different power reduction conditions. It also provides the ability to run the WDT from an entirely internal source that is not dependent on an external crystal and its associated components and wiring for increased reliability. • The Watchdog Clock (WDCLK) source can be selected from the Internal RC oscillator 7.14 Clocking and power control 7.14.1 Crystal oscillators The LPC1102 includes two independent oscillators. These are the Internal RC oscillator (IRC) and the Watchdog oscillator. Each oscillator can be used for more than one purpose as required in a particular application. Following reset, the LPC1102 will operate from the Internal RC oscillator until switched by software. This allows systems to operate without any external crystal and the bootloader code to operate at a known frequency. See Figure 4 for an overview of the LPC1102 clock generation.

LPC1102 clock generation block diagram 7.14.1.1 Internal RC oscillator The IRC may be used as the clock source for the WDT, and/or as the clock that drives the PLL and subsequently the CPU. The nominal IRC frequency is 12 MHz. The IRC is trimmed to 1 % accuracy over the entire voltage and temperature range. Upon power-up or any chip reset, the LPC1102 uses the IRC as the clock source. Software may later switch to one of the other available clock sources. 7.14.1.2 Watchdog oscillator The watchdog oscillator can be used as a clock source that directly drives the CPU or the watchdog timer. The watchdog oscillator nominal frequency is programmable between 7.8 kHz and 1.7 MHz. The frequency spread over processing and temperature is ±40 %. 7.14.2 System PLL The PLL accepts an input clock frequency in the range of 10 MHz to 25 MHz. The input frequency is multiplied up to a high frequency with a Current Controlled Oscillator (CCO). The multiplier can be an integer value from 1 to 32. The CCO operates in the range of 156 MHz to 320 MHz, so there is an additional divider in the loop to keep the CCO within its frequency range while the PLL is providing the desired output frequency. The PLL output frequency must be lower than 100 MHz. The output divider may be set to divide by 2, 4, 8, or 16 to produce the output clock. Since the minimum output divider value is 2, it is insured that the PLL output has a 50 % duty cycle. The PLL is turned off and bypassed LPC1102 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2011. All rights reserved.

The program must configure and activate the PLL, wait for the PLL to lock, and then connect to the PLL as a clock source. The PLL settling time is 100 μs. 7.14.3 Wake-up process The LPC1102 begins operation at power-up by using the 12 MHz IRC oscillator as the clock source. This allows chip operation to resume quickly. If an external clock or the PLL is needed by the application, software will need to enable these features and wait for them to stabilize before they are used as a clock source. 7.14.4 Power control The LPC1102 supports a variety of power control features. There are two special modes of processor power reduction: Sleep mode and Deep-sleep mode. The CPU clock rate may also be controlled as needed by changing clock sources, reconfiguring PLL values, and/or altering the CPU clock divider value. This allows a trade-off of power versus processing speed based on application requirements. In addition, a register is provided for shutting down the clocks to individual on-chip peripherals, allowing fine tuning of power consumption by eliminating all dynamic power use in any peripherals that are not required for the application. Selected peripherals have their own clock divider which provides even better power control. 7.14.4.1 Power profiles The power consumption in Active and Sleep modes can be optimized for the application through a simple call to the power profiles. The power configuration routine configures the LPC1102 for one of the following power modes: • Default mode corresponding to power configuration after reset. • CPU performance mode corresponding to optimized processing capability. • Efficiency mode corresponding to optimized balance of current consumption and CPU performance. • Low-current mode corresponding to lowest power consumption. In addition, the power profiles includes a routine to select the optimal PLL settings for a given system clock and PLL input clock. 7.14.4.2 Sleep mode When Sleep mode is entered, the clock to the core is stopped. Resumption from the Sleep mode does not need any special sequence but re-enabling the clock to the ARM core. In Sleep mode, execution of instructions is suspended until either a reset or interrupt occurs. Peripheral functions continue operation during Sleep mode and may generate interrupts to cause the processor to resume execution. Sleep mode eliminates dynamic power used by the processor itself, memory systems and related controllers, and internal buses. 7.14.4.3 Deep-sleep mode In Deep-sleep mode, the chip is in Sleep mode, and in addition all analog blocks are shut down except for the watchdog oscillator and the BOD circuit, which can be configured to remain running in Deep-sleep mode to allow a reset initiated by a timer or BOD event. Deep-sleep mode allows for additional power savings. LPC1102 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2011. All rights reserved. Product data sheet Rev. 3 — 18 April 2011 13 of 39 NXP Semiconductors LPC1102 32-bit ARM Cortex-M0 microcontroller Six of the GPIO pins (see Table 3) serve as external wake-up pins to a dedicated start logic to wake up the chip from Deep-sleep mode. The clock source should be switched to IRC before entering Deep-sleep mode unless the watchdog oscillator remains running in Deep-sleep mode. The IRC can be switched on and off glitch-free and provides a clean clock signal after start-up. 7.15 System control 7.15.1 Start logic The start logic connects external pins to corresponding interrupts in the NVIC. Each pin shown in Table 3 as input to the start logic has an individual interrupt in the NVIC interrupt vector table. The start logic pins can serve as external interrupt pins when the chip is running. In addition, an input signal on the start logic pins can wake up the chip from Deep-sleep mode when all clocks are shut down. The start logic must be configured in the system configuration block and in the NVIC before being used. 7.15.2 Reset Reset has four sources on the LPC1102: the RESET pin, the Watchdog reset, power-on reset (POR), and the BrownOut Detection (BOD) circuit. In addition, there is an ARM software reset. The RESET pin is a Schmitt trigger input pin. Assertion of chip reset by any source, once the operating voltage attains a usable level, starts the IRC and initializes the flash controller. A LOW-going pulse as short as 50 ns resets the part. When the internal Reset is removed, the processor begins executing at address 0, which is initially the Reset vector mapped from the boot block. At that point, all of the processor and peripheral registers have been initialized to predetermined values. 7.15.3 Brownout detection The LPC1102 includes four levels for monitoring the voltage on the VDD pin. If this voltage falls below one of the four selected levels, the BOD asserts an interrupt signal to the NVIC. This signal can be enabled for interrupt in the Interrupt Enable Register in the NVIC in order to cause a CPU interrupt; if not, software can monitor the signal by reading a dedicated status register. Four additional threshold levels can be selected to cause a forced reset of the chip. 7.15.4 Code security (Code Read Protection - CRP) This feature of the LPC1102 allows user to enable different levels of security in the system so that access to the on-chip flash and use of the Serial Wire Debugger (SWD) can be restricted. When needed, CRP is invoked by programming a specific pattern into a dedicated flash location. IAP commands are not affected by the CRP. There are three levels of Code Read Protection: 1. CRP1 disables access to the chip via the SWD and allows partial flash update (excluding flash sector 0). This mode is useful when CRP is required and flash field updates are needed but all sectors can not be erased.

CRP2 disables access to the chip via the SWD and only allows full flash erase and update. 3. Running an application with level CRP3 selected fully disables any access to the chip via the SWD pins. Remark: The LPC1102 does not provide an ISP entry pin to be monitored at reset. For all three CRP levels, the user’s application code must provide a flash update mechanism which reinvokes ISP by defining a user-selected PIO pin for ISP entry. CAUTION If Code Read Protection of any level (CRP1, CRP2 or CRP3) is selected, no future factory testing can be performed on the device. 7.15.5 APB interface The APB peripherals are located on one APB bus. 7.15.6 AHBLite The AHBLite connects the CPU bus of the ARM Cortex-M0 to the flash memory, the main static RAM, and the Boot ROM. 7.15.7 External interrupt inputs All GPIO pins can be level or edge sensitive interrupt inputs. In addition, start logic inputs serve as external interrupts (see Section 7.15.1). 7.16 Emulation and debugging Debug functions are integrated into the ARM Cortex-M0. Serial wire debug with four breakpoints and two watchpoints is supported. Remark: Care must be taken when using the SPI because the SPI clock SCK and the serial wire debug clock SWCLK share the same pin on the WLCSP16 package. Once the SPI is enabled, the serial wire debugger is no longer available. LPC1102 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2011. All rights reserved.

Application information 11.1 ADC usage notes The following guidelines show how to increase the performance of the ADC in a noisy environment beyond the ADC specifications listed in Table 6: • The ADC input trace must be short and as close as possible to the LPC1102 chip. • The ADC input traces must be shielded from fast switching digital signals and noisy power supply lines. • Because the ADC and the digital core share the same power supply, the power supply line must be adequately filtered. • To improve the ADC performance in a very noisy environment, put the device in Sleep mode during the ADC conversion. 11.2 XTAL input The input voltage to the on-chip oscillators is limited to 1.8 V. If the oscillator is driven by a clock in slave mode, it is recommended that the input be coupled through a capacitor with Ci = 100 pF. To limit the input voltage to the specified range, choose an additional capacitor to ground Cg which attenuates the input voltage by a factor Ci/(Ci + Cg). In slave mode, a minimum of 200 mV (RMS) is needed. LPC1xxx XTALIN Ci 100 pF Cg 002aae788 Fig 19. Slave mode operation of the on-chip oscillator In slave mode the input clock signal should be coupled by means of a capacitor of 100 pF (Figure 19), with an amplitude between 200 mV (RMS) and 1000 mV (RMS). This corresponds to a square wave signal with a signal swing of between 280 mV and 1.4 V. 11.3 Standard I/O pad configuration Figure 20 shows the possible pin modes for standard I/O pins with analog input function: • • • • • LPC1102 Digital output driver Digital input: Pull-up enabled/disabled Digital input: Pull-down enabled/disabled Digital input: Repeater mode enabled/disabled Analog input All information provided in this document is subject to legal disclaimers. © NXP B.V. 2011.
