These are stress ratings only, and functional operation of the device at these or any other conditions outside of those listed in the operational sections of this specification is not implied. Exposure to any absolute maximum rating for extended periods may affect device performance and reliability. (2) The DC input voltage on any pin should not be lower than -0.5 V or higher than VCC + 0.5 V. During transitions, the voltage on any pin may undershoot to no less than -1.5 V or overshoot to no more than VCC + 1.5 V, for periods of less than 20 ns. (3) These parameters are tested initially and after a design or process change that affects the parameter according to appropriate AEC-Q100 and JEDEC test methods. (4) Page Mode, VCC = 5 V, 25°C (5) When not driven, the WP pin is pulled down to GND internally. For improved noise immunity, the internal pull-down is relatively strong; therefore the external driver must be able to supply the pull-down current when attempting to drive the input HIGH. To conserve power, as the input level exceeds the trip point of the CMOS input buffer (~ 0.5 x VCC), the strong pull-down reverts to a weak current source. © 2006 by Catalyst Semiconductor, Inc.

C CAT24C01/02/04/08/16 POWER-ON RESET (POR) Each CAT24Cxx* incorporates Power-On Reset (POR) circuitry which protects the internal logic against powering up in the wrong state. A CAT24Cxx device will power up into Standby mode after VCC exceeds the POR trigger level and will power down into Reset mode when VCC drops below the POR trigger level. This bi-directional POR feature protects the device against ‘brown-out’ failure following a temporary loss of power. * For common features, the CAT24C01/02/04/08/16 will be refered to as CAT24Cxx I2C BUS PROTOCOL The I2C bus consists of two ‘wires’, SCL and SDA. The two wires are connected to the VCC supply via pull-up resistors. Master and Slave devices connect to the 2wire bus via their respective SCL and SDA pins. The transmitting device pulls down the SDA line to ‘transmit’ a ‘0’ and releases it to ‘transmit’ a ‘1’. Data transfer may be initiated only when the bus is not busy (see A.C. Characteristics). During data transfer, the SDA line must remain stable while the SCL line is HIGH. An SDA transition while SCL is HIGH will be interpreted as a START or STOP condition (Figure 1). The START condition precedes all commands. It consists of a HIGH to LOW transition on SDA while SCL is HIGH. The START acts as a ‘wake-up’ call to all receivers. Absent a START, a Slave will not respond to commands. The STOP condition completes all commands. It consists of a LOW to HIGH transition on SDA while SCL is HIGH. Device Addressing The Master initiates data transfer by creating a START condition on the bus. The Master then broadcasts an 8-bit serial Slave address. For normal Read/Write operations, the first 4 bits of the Slave address are fixed at 1010 (Ah). The next 3 bits are used as programmable address bits when cascading multiple devices and/or as internal address bits. The last bit of the slave address, R/W, specifies whether a Read (1) or Write (0) operation is to be performed. The 3 address space extension bits are assigned as illustrated in Figure 2. A2, A1 and A0 must match the state of the external address pins, and a10, a9 and a8 are internal address bits. Acknowledge After processing the Slave address, the Slave responds with an acknowledge (ACK) by pulling down the SDA line during the 9th clock cycle (Figure 3). The Slave will also acknowledge the address byte and every data byte presented in Write mode. In Read mode the Slave shifts out a data byte, and then releases the SDA line during the 9th clock cycle. As long as the Master acknowledges the data, the Slave will continue transmitting. The Master terminates the session by not acknowledging the last data byte (NoACK) and by issuing a STOP condition. Bus timing is illustrated in Figure 4. PIN DESCRIPTION SCL: The Serial Clock input pin accepts the Serial Clock generated by the Master. SDA: The Serial Data I/O pin receives input data and transmits data stored in EEPROM. In transmit mode, this pin is open drain. Data is acquired on the positive edge, and is delivered on the negative edge of SCL. A0, A1 and A2: The Address inputs set the device address when cascading multiple devices. When not driven, these pins are pulled LOW internally. WP: The Write Protect input pin inhibits all write operations, when pulled HIGH. When not driven, this pin is pulled LOW internally. FUNCTIONAL DESCRIPTION The CAT24Cxx supports the Inter-Integrated Circuit (I2C) Bus data transmission protocol, which defines a device that sends data to the bus as a transmitter and a device receiving data as a receiver. Data flow is controlled by a Master device, which generates the serial clock and all START and STOP conditions. The CAT24Cxx acts as a Slave device. Master and Slave alternate as either transmitter or receiver. Doc. No. 1115, Rev. C 4 © 2006 by Catalyst Semiconductor, Inc.

C CAT24C01/02/04/08/16 WRITE OPERATIONS Byte Write In Byte Write mode, the Master sends the START condition and the Slave address with the R/W bit set to zero to the Slave. After the Slave generates an acknowledge, the Master sends the byte address that is to be written into the address pointer of the CAT24Cxx. After receiving another acknowledge from the Slave, the Master transmits the data byte to be written into the addressed memory location. The CAT24Cxx device will acknowledge the data byte and the Master generates the STOP condition, at which time the device begins its internal Write cycle to nonvolatile memory (Figure 5). While this internal cycle is in progress (tWR), the SDA output will be tri-stated and the CAT24Cxx will not respond to any request from the Master device (Figure 6). Page Write The CAT24Cxx writes up to 16 bytes of data in a single write cycle, using the Page Write operation (Figure 7). The Page Write operation is initiated in the same manner as the Byte Write operation, however instead of terminating after the data byte is transmitted, the Master is allowed to send up to fifteen additional bytes. After each byte has been transmitted the CAT24Cxx will respond with an acknowledge and internally increments the four low order address bits. The high order bits that define the page address remain unchanged. If the Master transmits more than sixteen bytes prior to sending the STOP condition, the address counter ‘wraps around’ to the beginning of page and previously transmitted data will be overwritten. Once all sixteen bytes are received and the STOP condition has been sent by the Master, the internal Write cycle begins. At this point all received data is written to the CAT24Cxx in a single write cycle. Acknowledge Polling The acknowledge (ACK) polling routine can be used to take advantage of the typical write cycle time. Once the stop condition is issued to indicate the end of the host’s write operation, the CAT24Cxx initiates the internal write cycle. The ACK polling can be initiated immediately. This involves issuing the start condition followed by the slave address for a write operation. If the CAT24Cxx is still busy with the write operation, NoACK will be returned. If the CAT24Cxx has completed the internal write operation, an ACK will be returned and the host can then proceed with the next read or write operation. Hardware Write Protection With the WP pin held HIGH, the entire memory is protected against Write operations. If the WP pin is left floating or is grounded, it has no impact on the operation of the CAT24Cxx. The state of the WP pin is strobed on the last falling edge of SCL immediately preceding the first data byte (Figure 8). If the WP pin is HIGH during the strobe interval, the CAT24Cxx will not acknowledge the data byte and the Write request will be rejected. Delivery State The CAT24Cxx is shipped erased, i.e., all bytes are FFh. Doc. No. 1115, Rev. C 6 © 2006 by Catalyst Semiconductor, Inc.

C CAT24C01/02/04/08/16 READ OPERATIONS Immediate Read Upon receiving a Slave address with the R/W bit set to ‘1’, the CAT24Cxx will interpret this as a request for data residing at the current byte address in memory. The CAT24Cxx will acknowledge the Slave address, will immediately shift out the data residing at the current address, and will then wait for the Master to respond. If the Master does not acknowledge the data (NoACK) and then follows up with a STOP condition (Figure 9), the CAT24Cxx returns to Standby mode. Selective Read Selective Read operations allow the Master device to select at random any memory location for a read operation. The Master device first performs a ‘dummy’ write operation by sending the START condition, slave address and byte address of the location it wishes to read. After the CAT24Cxx acknowledges the byte address, the Master device resends the START condition and the slave address, this time with the R/W bit set to one. The CAT24Cxx then responds with its acknowledge and sends the requested data byte. The Master device does not acknowledge the data (NoACK) but will generate a STOP condition (Figure 10). Sequential Read If during a Read session, the Master acknowledges the 1st data byte, then the CAT24Cxx will continue transmitting data residing at subsequent locations until the Master responds with a NoACK, followed by a STOP (Figure 11). In contrast to Page Write, during Sequential Read the address count will automatically increment to and then wrap-around at end of memory (rather than end of page). In the CAT24C01, the internal address count will not wrap around at the end of the 128 byte memory space. Doc. No. 1115, Rev. C 8 © 2006 by Catalyst Semiconductor, Inc.
