Device Operation
CLOCK DATA TRANSITIONS: normally pulled high with external device. Data change only during time periods (refer Data Validity timing diagram). Data changes during high periods will indicate start stop condition defined below. START CONDITION: high-to-low transition with high start condition which must precede other command (refer Start Stop Definition timing diagram). STOP CONDITION: low-to-high transition with high stop condition. After read sequence, stop command will place EEPROM standby power mode (refer Start Stop Definition timing diagram). ACKNOWLEDGE: addresses data words serially transmitted from EEPROM words. EEPROM sends zero acknowledge that received each word. This happens during ninth clock cycle. STANDBY MODE: AT24C02A/04A/08A/16A features power standby mode which enabled: upon power-up after receipt STOP completion internal operations. MEMORY RESET: After interruption protocol, power loss system reset, 2-wire part reset following these steps: Clock cycles, look high each cycle while high then create start condition high.

Device Addressing
EEPROM devices require device address word following start condition enable chip read write operation (refer Figure device address word consists mandatory one, zero sequence first four most significant bits shown. This common EEPROM devices. next bits device address bits EEPROM. These bits must compare their corresponding hard-wired input pins. EEPROM only uses device address bits with third being memory page address bit. device address bits must compare their corresponding hard-wired input pins. no-connect. EEPROM only uses device address with next bits being memory page addressing. must compare corresponding hard-wired input pin. pins no-connect. EEPROM does device address pins, which limits number devices single one. pins no-connects. eighth device address read/write operation select bit. read operation initiated this high write operation initiated this low. Upon compare device address, EEPROM will output zero. compare made, chip will return standby state.
Write Operations
BYTE WRITE: write operation requires data word address following device address word acknowledgement. Upon receipt this address, EEPROM will again respond with zero then clock first data word. Following receipt data word, EEPROM will output zero addressing device, such microcontroller, must terminate write sequence with stop condition. this time EEPROM enters internally-timed write cycle, nonvolatile memory. inputs disabled during this write cycle EEPROM will respond until write complete (refer Figure PAGE WRITE: EEPROM capable 8-byte page write, devices capable 16-byte page writes. page write initiated same byte write, microcontroller does send stop condition after first data word clocked Instead, after EEPROM acknowledges receipt first data word, microcontroller transmit seven (2K) fifteen (4K, 16K) more data words. EEPROM will respond with zero after each data word received. microcontroller must terminate page write sequence with stop condition (refer Figure data word address lower three (2K) four (4K, 16K) bits internally incremented following receipt each data word. higher data word address bits incremented, retaining memory page location. When word address, internally generated, reaches page boundary, following byte placed beginning same page. more than eight (2K) sixteen (4K, 16K) data words transmitted EEPROM, data word address will "roll over" previous data will overwritten. ACKNOWLEDGE POLLING: Once internally-timed write cycle started EEPROM inputs disabled, acknowledge polling initiated. This involves sending start condition followed device address word. read/write representative operation desired. Only internal write cycle completed will EEPROM respond with zero allowing read write sequence continue.
0976K-SEEPR-11/03
Read Operations
Read operations initiated same write operations with exception that read/write select device address word one. There three read operations: current address read, random address read sequential read. CURRENT ADDRESS READ: internal data word address counter maintains last address accessed during last read write operation, incremented one. This address stays valid between operations long chip power maintained. address "roll over" during read from last byte last memory page first byte first page. address "roll over" during write from last byte current page first byte same page. Once device address with read/write select clocked acknowledged EEPROM, current address data word serially clocked out. microcontroller does respond with input zero does generate following stop condition (refer Figure RANDOM READ: random read requires "dummy" byte write sequence load data word address. Once device address word data word address clocked acknowledged EEPROM, microcontroller must generate another start condition. microcontroller initiates current address read sending device address with read/write select high. EEPROM acknowledges device address serially clocks data word. microcontroller does respond with zero does generate following stop condition (refer Figure SEQUENTIAL READ: Sequential reads initiated either current address read random address read. After microcontroller receives data word, responds with acknowledge. long EEPROM receives acknowledge, will continue increment data word address serially clock sequential data words. When memory address limit reached, data word address will "roll over" sequential read will continue. sequential read operation terminated when microcontroller does respond with zero does generate following stop condition (refer Figure Figure Device Address
