The device uses ECC (Error Correction Code) logic with 6 ECC bits to correct one bit error in 4 data bytes. Therefore, when a single byte has to be written, 4 bytes (including the ECC bits) are re-programmed. It is recommended to write by multiple of 4 bytes in order to benefit from the maximum number of write cycles. Table 3. D.C.

When not driven, the WP, A0, A1, A2 pins are 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. www.onsemi.com 2 CAT24C512C8UTR Table 5.

The 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 behavior protects the device against brown−out failure, following a temporary loss of power. 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 2). START 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. Pin Description SCL: The Serial Clock input pin accepts the Serial Clock signal 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. These pins have on−chip pull−down resistors. WP: The Write Protect input pin inhibits all write operations, when pulled HIGH. This pin has an on−chip pull−down resistor. STOP The STOP condition completes all commands. It consists of a LOW to HIGH transition on SDA while SCL is HIGH. The STOP starts the internal Write cycle (when following a Write command) or sends the Slave into standby mode (when following a Read command). 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 3). The next 3 bits, A2, A1 and A0, select one of 8 possible Slave devices. The last bit, R/W, specifies whether a Read (1) or Write (0) operation is to be performed. Functional Description The CAT24C512 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 CAT24C512 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. 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 4). The Slave will also acknowledge the byte address 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. If the Master acknowledges the data, then the Slave continues transmitting. The Master terminates the session by not acknowledging the last data byte (NoACK) and by sending a STOP to the Slave. Bus timing is illustrated in Figure 5. 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 2−wire bus via their respective SCL and SDA pins. The transmitting www.onsemi.com 4 CAT24C512C8UTR SCL SDA START CONDITION STOP CONDITION Figure 2.

Polling is implemented by interrogating the device with a ‘Selective Read’ command (see READ OPERATIONS). The CAT24C512 will not acknowledge the Slave address, as long as internal Write is in progress. Byte Write In Byte Write mode the Master sends a START, followed by Slave address, two byte address and data to be written (Figure 6). The Slave acknowledges all 4 bytes, and the Master then follows up with a STOP, which in turn starts the internal Write operation (Figure 7). During internal Write, the Slave will not acknowledge any Read or Write request from the Master. 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 CAT24C512. The state of the WP pin is strobed on the last falling edge of SCL immediately preceding the first data byte (Figure 9). If the WP pin is HIGH during the strobe interval, the CAT24C512 will not acknowledge the data byte and the Write request will be rejected. Page Write The CAT24C512 contains 65,536 bytes of data, arranged in 512 pages of 128 bytes each. A two byte address word, following the Slave address, points to the first byte to be written. The most significant 9 bits (A15 to A7) identify the page and the last 7 bits identify the byte within the page. Up to 128 bytes can be written in one Write cycle (Figure 8). The internal byte address counter is automatically incremented after each data byte is loaded. If the Master transmits more than 128 data bytes, then earlier bytes will be overwritten by later bytes in a ‘wrap−around’ fashion (within the selected page). The internal Write cycle starts immediately following the STOP. Delivery State The CAT24C512 is shipped erased, i.e., all bytes are FFh. www.onsemi.com 6 CAT24C512C8UTR S T BUS ACTIVITY: A MASTER R T SLAVE ADDRESS BYTE ADDRESS A15 − A8 A7 − A0 S T O P DATA P SDA LINE S A C K A C K A C K A C K Figure 6.

Here the START is followed by the Slave address (with the R/W bit set to ‘0’) and the desired two byte address. Instead of following up with data, the Master then issues a 2nd START, followed by the ‘Immediate Address Read’ sequence, as described earlier. Immediate Address Read In standby mode, the CAT24C512 internal address counter points to the data byte immediately following the last byte accessed by a previous operation. If that ‘previous’ byte was the last byte in memory, then the address counter will point to the 1st memory byte, etc. When, following a START, the CAT24C512 is presented with a Slave address containing a ‘1’ in the R/W bit position (Figure 10), it will acknowledge (ACK) in the 9th clock cycle, and will then transmit data being pointed at by the internal address counter. The Master can stop further transmission by issuing a NoACK, followed by a STOP condition. Sequential Read If the Master acknowledges the 1st data byte transmitted by the CAT24C512, then the device will continue transmitting as long as each data byte is acknowledged by the Master (Figure 12). If the end of memory is reached during sequential Read, then the address counter will ‘wrap−around’ to the beginning of memory, etc. Sequential Read works with either ‘Immediate Address Read’ or ‘Selective Read’, the only difference being the starting byte address. Selective Read The Read operation can also be started at an address different from the one stored in the internal address counter.
