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. Max 8 6 200 1 Units pF pF μA μA Doc.

J CAT24C128 POWER-ON RESET (POR) The CAT24C128 incorporates Power-On Reset (POR) circuitry which protects the device against powering up in the wrong state. The CAT24C128 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. 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. The first 4 bits of the Slave address are set to 1010, for normal Read/Write operations (Figure 2). The next 3 bits, A2, A1 and A0, select one of 8 possible Slave devices and must match the state of the external address pins. The last bit, R/W, specifies whether a Read (1) or Write (0) operation is to be performed. 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 all address bytes 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 pins accept the device address. 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 CAT24C128 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 CAT24C128 acts as a Slave device. Master and Slave alternate as either transmitter or receiver. Up to 8 devices may be connected to the bus as determined by the device address inputs A0, A1, and A2. Doc. No. MD-1103, Rev.

J CAT24C128 WRITE OPERATIONS Byte Write Upon receiving a Slave address with the R/W bit set to ‘0’, the CAT24C128 will interpret the next two bytes as address bytes These bytes are used to initialize the internal address counter; the 2 most significant bits are ‘don’t care’, the next 8 point to one of 256 available pages and the last 6 point to a location within a 64 byte page. A byte following the address bytes will be interpreted as data. The data will be loaded into the Page Write Buffer and will eventually be written to memory at the address specified by the 14 active address bits provided earlier. The CAT24C128 will acknowledge the Slave address, address bytes and data byte. The Master then starts the internal Write cycle by issuing a STOP condition (Figure 5). During the internal Write cycle (tWR), the SDA output will be tri-stated and additional Read or Write requests will be ignored (Figure 6). Page Write By continuing to load data into the Page Write Buffer after the 1st data byte and before issuing the STOP condition, up to 64 bytes can be written simultaneously during one internal Write cycle (Figure 7). If more data bytes are loaded than locations available to the end of page, then loading will continue from the beginning of page, i.e. the page address is latched and the address count automatically increments to and then wrapsaround at the page boundary. Previously loaded data can thus be overwritten by new data. What is eventually written to memory reflects the latest Page Write Buffer contents. Only data loaded within the most recent Page Write sequence will be written to memory. Acknowledge Polling The ready/busy status of the CAT24C128 can be ascertained by sending Read or Write requests immediately following the STOP condition that initiated the internal Write cycle. As long as internal Write is in progress, the CAT24C128 will not acknowledge the Slave address. 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 im pact on the operation of the CAT24C128. 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 CAT24C128 will not acknowledge the data byte and the Write request will be rejected. Delivery State The CAT24C128 is shipped erased, i.e., all bytes are FFh. Doc. No. MD-1103, Rev. J 6 © Catalyst Semiconductor, Inc. Characteristics subject to change without notice CAT24C128 Figure 5.

J CAT24C128 READ OPERATIONS Immediate Read Upon receiving a Slave address with the R/W bit set to ‘1’, the CAT24C128 will interpret this as a request for data residing at the current byte address in memory. The CAT24C128 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 CAT24C128 returns to Standby mode. Selective Read To read data residing at a specific location, the internal address counter must first be initialized as described under Byte Write. If rather than following up the two address bytes with data, the Master instead follows up with an Immediate Read sequence, then the CAT24C128 will use the 14 active addres bits to initialize the internal address counter and will shift out data residing at the corresponding location. If the Master does not acknowledge the data (NoACK) and then follows up with a STOP condition (Figure 10), the CAT24C128 returns to Standby mode. Sequential Read If during a Read session the Master acknowledges the 1st data byte, then the CAT24C128 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). Doc. No. MD-1103, Rev.
