1. Pin Description SERIAL CLOCK (): The input is used to positive edge clock data into each EEPROM device and negative edge clock data out of each device. SERIAL DATA (SDA): The SDA pin is bidirectional for serial data transfer. This pin is opendrain driven and may be wire-ored with any number of other open-drain or open-collector devices. DEVICE/PAGE ADDRESSES (A2, A1, A0): The A2, A1 and A0 pins are device address inputs that are hard wired for the. As many as eight 1K devices may be addressed on a single bus system (device addressing is discussed in detail under the Device Addressing section). WRITE PROTECT (WP): The has a write protect pin that provides hardware data protection. The write protect pin allows normal read/write operations when connected to ground (GND). When the write protect pin is connected to V CC, the write protection feature is enabled and operates as shown in Table 1-1. Table 1-1.

3. Device Operation CLOCK and DATA TRANSITIONS: The SDA pin is normally pulled high with an external device. Data on the SDA pin may change only during low time periods (see Figure 5-2 on page 8). Data changes during high periods will indicate a start or stop condition as defined below. START CONDITION: A high-to-low transition of SDA with high is a start condition which must precede any other command (see Figure 5-3 on page 8). STOP CONDITION: A low-to-high transition of SDA with high is a stop condition. After a read sequence, the stop command will place the EEPROM in a standby power mode (see Figure 5-3 on page 8). ACKNOWLEDGE: All addresses and data words are serially transmitted to and from the EEPROM in 8-bit words. The EEPROM sends a zero to acknowledge that it has received each word. This happens during the ninth clock cycle. STANDBY MODE: The features a low-power standby mode which is enabled: (a) upon power-up and (b) after the receipt of the STOP bit and the completion of any internal operations. 2-WIRE SOFTWARE RESET: After an interruption in protocol, power loss or system reset, any 2-wire part can be protocol reset by following these steps: (a) Create a start bit condition, (b) Clock 9 cycles, (c) Create another start bit followed by a stop bit condition as shown below. The device is ready for next communication after above steps have been completed. Start bit Dummy Clock Cycles Start bit Stop bit 1 2 3 8 9 SDA 6

6. Device Addressing 7. Write Operations The 1K EEPROM device requires an 8-bit device address word following a start condition to enable the chip for a read or write operation (refer to Figure 8-1). The device address word consists of a mandatory one, zero sequence for the first four most significant bits as shown. This is common to all the EEPROM devices. The next 3 bits are the A2, A1 and A0 device address bits for the 1K EEPROM. These 3 bits must compare to their corresponding hard-wired input pins. The eighth bit of the device address is the read/write operation select bit. A read operation is initiated if this bit is high and a write operation is initiated if this bit is low. Upon a compare of the device address, the EEPROM will output a zero. If a compare is not made, the chip will return to a standby state. BYTE WRITE: A write operation requires an 8-bit data word address following the device address word and acknowledgment. Upon receipt of this address, the EEPROM will again respond with a zero and then clock in the first 8-bit data word. Following receipt of the 8-bit data word, the EEPROM will output a zero and the addressing device, such as a microcontroller, must terminate the write sequence with a stop condition. At this time the EEPROM enters an internally timed write cycle, t WR, to the nonvolatile memory. All inputs are disabled during this write cycle and the EEPROM will not respond until the write is complete (see Figure 8-2 on page 10). PAGE WRITE: The 1K EEPROM is capable of an 8-byte page write. A page write is initiated the same as a byte write, but the microcontroller does not send a stop condition after the first data word is clocked in. Instead, after the EEPROM acknowledges receipt of the first data word, the microcontroller can transmit up to seven data words. The EEPROM will respond with a zero after each data word received. The microcontroller must terminate the page write sequence with a stop condition (see Figure 8-3 on page 11). The data word address lower three bits are internally incremented following the receipt of each data word. The higher data word address bits are not incremented, retaining the memory page row location. When the word address, internally generated, reaches the page boundary, the following byte is placed at the beginning of the same page. If more than eight data words are transmitted to the EEPROM, the data word address will roll over and previous data will be overwritten. ACKNOWLEDGE POLLING: Once the internally timed write cycle has started and the EEPROM inputs are disabled, acknowledge polling can be initiated. This involves sending a start condition followed by the device address word. The read/write bit is representative of the operation desired. Only if the internal write cycle has completed will the EEPROM respond with a zero allowing the read or write sequence to continue. 9

8. Read Operations Read operations are initiated the same way as write operations with the exception that the read/write select bit in the device address word is set to one. There are three read operations: current address read, random address read and sequential read. CURRENT ADDRESS READ: The internal data word address counter maintains the last address accessed during the last read or write operation, incremented by one. This address stays valid between operations as long as the chip power is maintained. The address roll over during read is from the last byte of the last memory page to the first byte of the first page. The address roll over during write is from the last byte of the current page to the first byte of the same page. Once the device address with the read/write select bit set to one is clocked in and acknowledged by the EEPROM, the current address data word is serially clocked out. The microcontroller does not respond with an input zero but does generate a following stop condition (see Figure 8-4 on page 11). RANDOM READ: A random read requires a dummy byte write sequence to load in the data word address. Once the device address word and data word address are clocked in and acknowledged by the EEPROM, the microcontroller must generate another start condition. The microcontroller now initiates a current address read by sending a device address with the read/write select bit high. The EEPROM acknowledges the device address and serially clocks out the data word. The microcontroller does not respond with a zero but does generate a following stop condition (see Figure 8-5 on page 11). SEQUENTIAL READ: Sequential reads are initiated by either a current address read or a random address read. After the microcontroller receives a data word, it responds with an acknowledge. As long as the EEPROM receives an acknowledge, it will continue to increment the data word address and serially clock out sequential data words. When the memory address limit is reached, the data word address will roll over and the sequential read will continue. The sequential read operation is terminated when the microcontroller does not respond with a zero but does generate a following stop condition (see Figure 8-6 on page 12). Figure 8-1.
