I CAT34RC02 FUNCTIONAL DESCRIPTION The CAT34RC02 supports the I2C (2-wire) Bus data transmission protocol. This Inter-Integrated Circuit Bus protocol defines any device that sends data to the bus to be a transmitter and any device receiving data to be a receiver. Data transfer is controlled by the Master device which generates the serial clock and all START and STOP conditions for bus access. The CAT34RC02 operates as a Slave device. Both the Master and Slave devices can operate as either transmitter or receiver, but the Master alone assigns those roles. A maximum of 8 devices may be connected to the bus as determined by the device address inputs A0, A1, and A2. PIN DESCRIPTIONS SCL: Serial Clock The serial clock input pin is used to clock all data transfers into or out of the device. SDA: Serial Data/Address The bidirectional serial data/address pin is used to transfer data into and out of the device. This pin is an open drain output in transmit mode. A0, A1, A2: Device Address Inputs These inputs set the device address. When left floating, the address pins are internally pulled to ground. WP: Write Protect This input, when grounded or left floating, allows write operations to the entire memory. When this pin is tied to VCC, the entire memory is write protected. Figure 1.

I STOP BIT 4 CAT34RC02 I2C BUS PROTOCOL The I2C bus consists of two ‘wires’, SCL and SDA. The two ‘wires’ are connected to the supply (VCC) via pull-up resistors. Master and Slave devices connect to the 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’. (1) Data transfer may be initiated only when the bus is not busy (see A.C. Characteristics). (2) During a data transfer, the data line must remain stable whenever the SCL line is high. An SDA transition while SCL is high will be interpreted as a START or STOP condition. START Condition The START Condition precedes all commands. It consists of a HIGH to LOW transition on SDA while SCL is HIGH. The START condition acts as a ‘wake-up’ call for the Slave devices. A Slave will not respond to commands unless the MASTER generates a START condition. STOP Condition The STOP condition completes all commands. It consists of a LOW to HIGH transition on SDA while SCL is HIGH. The STOP condition starts the internal write cycle, when following a WRITE command and sends the Slave into standby mode, when following a READ command. Device Addressing The Master initiates a data transfer by creating a START condition on the bus. The Master then broadcasts an 8bit serial Slave address. The four most significant bits of the Slave address (the ‘preamble’) are fixed to 1010 (Ah), for normal read/write operations and 0110 (6h) for Software Write Protect (SWP) operations (Fig. 5). The next three bits, A2, A1 and A0, select one of eight possible Slave devices. 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. The Slave will aslo acknowledge the 8-bit byte address and every data byte presented in WRITE mode. In READ mode the Slave shifts out eight bits of data, and then ‘releases’ the SDA line durng the 9th clock cycle. If the Master acknowledges in the 9th clock cycle (by pulling down the SDA line), then the Slave continues transmitting. When data transfer is complete, the Master responds with a NoACK (it does not acknowledge the last data byte) and the Slave stops transmitting and waits for a STOP condition. Figure 4.

I CAT34RC02 WRITE OPERATIONS Byte Write In Byte Write mode the Master creates a START condition, and then broadcasts the Slave address, byte address and data to be written. The Slave acknowledges the three bytes by pulling down the SDA line during the 9th clock cycle following each byte. The Master creates a STOP condition after the last ACK from the Slave, which then starts the internal write operation (Fig. 6). During internal write, the Slave will ignore any read/write request from the Master. Page Write The CAT34RC02 contains 256 bytes of data, arranged in 16 pages of 16 bytes each. The page is selected by the four most significant bits of the address byte presented to the device after the Slave address, while the four least significant bits point to the byte within the page. By ‘loading’ more than one data byte into the device, up to an entire page can be written in one write cycle (Fig. 7). The internal byte address counter will increment after each data byte. If the Master transmits more than 16 data bytes, then earlier bytes will be overwritten by later bytes in a ‘wrap-around’ fashion within the selected page. The internal write cycle is started following the STOP condition created by the Master. Acknowledge Polling Acknowledge polling can be used to determine if the CAT34RC02 is busy writing or is ready to accept commands. Polling is implemented by sending a ‘Selective Read’ command (described under READ OPERATIONS) to the device. The CAT34RC02 will not acknowledge the Slave address, as long as internal write is in progress. WRITE PROTECTION Hardware Write Protection With the WP pin held HIGH, the entire memory, as well as the SWP flags are protected against WRITE operations (Fig. 9). If the WP pin is left floating or is grounded. then it has no impact on the operation of the CAT34RC02. Software Write Protection The lower half of memory (first 128 bytes) can be protected against WRITE operations by setting one of two Software Write Protection (SWP) flags/switches. The PSWP (Permanent Software Write Protection) flag can be set but not cleared by the user. The RSWP (Reversible Software Write Protection) flag can be set and cleared by the user. Whereas the PSWP flag can be set ‘in-system’, the RSWP flag is meant to be used during testing. RSWP commands require the presence of a very high voltage (higher than VCC) on address pin A0 and fixed logic levels for the other two address pins. The CAT34RC02 is shipped ‘unprotected’. The state of the SWP flags can be read by issuing an ‘Immediate Address Read’ command, with the Slave address ‘preamble’ set to 0110 (6h) instead of the ‘normal’ 1010 (Ah). A SWP READ will return the complemented versions of the two flags in the last two slots of the resulting data byte; the other six more significant bits in the data byte have no meaning to the user (Fig. 11).

No. 1052, Rev. I 6 CAT34RC02 The PSWP flag can be set (forever) by issuing a ‘Byte Write’ command, with the Slave address preamble set to ‘6h’, followed by a ‘don’t care’ address, followed by ‘don’t care’ data and a STOP condition. The CAT34RC02 will acknowledge the Slave address, dummy byte address and dummy data (Fig. 10). The PSWP flag will be permanently set (after the internal write cycle is completed). The SWP commands are shown in Table 1. Table 1. SWP Commands command attempts to ‘reaffirm’ one of the two switches, then the CAT34RC02 will not acknowledge the command itself. In addition, the CAT34RC02 will not acknowledge a ‘reaffirming’ SWP command, even if the WP pin is LOW. READ OPERATIONS Immediate Address Read In standby mode, the CAT34RC02 internal address counter points to the data byte immediately following the last byte accessed by a previous operation. If the ‘previous’ byte was the last byte in memory, then the address counter will point to the first memory byte, etc. If the CAT34RC02 decodes a Slave address with a ‘1’ in the R/W bit position (Fig. 8), it will issue an ACK in the 9th clock cycle, and will then transmit the data byte being pointed at by the address counter. The Master can then stop further transmission by issuing a NoACK, followed by a STOP condition. Selective Read The READ operation can also be started at an address different from the one stored in the address counter. The address counter can be ‘initialized’ by performing a ‘dummy’ WRITE operation (Fig. 12). The START condition is followed by the Slave address (with the R/W bit set to ‘0’) and the desired 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. Sequential Read If the Master acknowledges the 1st data byte transmitted Slave Address PIN Command SWP READ RSWP SET RSWP CLEAR PSWP SET A2 A2 0 0 A2 A1 A1 0 1 A1 A0 A0 VHV VHV A0 B7 0 0 0 0 Preamble B6 1 1 1 1 B5 1 1 1 1 B4 0 0 0 0 Device Address B3 A2 0 0 A2 B2 A1 0 1 A1 B1 A0 1 1 A0 R/W B0 1 0 0 0 The CAT34RC02 will not acknowledge RSWP or PSWP commands, once the PSWP flag is set. If the PSWP flag is not set, but the WP pin is HIGH, then the CAT34RC02 will react to RSWP or PSWP commands as follows: if the command attempts to ‘flip’ one of the two SWP switches, then the CAT34RC02 will respond the same way the regular memory would, i.e. the command and address (in this case dummy) are acknowledged, but the data (in this case dummy) will not be acknowledged; if the Figure 8.

I CAT34RC02 by the CAT34RC02, then the device will continue transmitting as long as each data byte is acknowledged by the Master (Fig. 13). If the end of memory is reached during sequential READ, the address counter will ‘wraparound’ 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.
