Write Operations
Byte Write:
A write operation requires an 8-bit device address word with R/W = “0”. Then the EEPROM sends
acknowledgment "0" at the ninth clock cycle. After these, the 8kbit to 16kbit EEPROMs receive 8-bit
memory address word, on the other hand the 32kbit and 64kbit EEPROMs receive 2 sequence 8-bit
memory address words. Upon receipt of this memory address, the EEPROM outputs acknowledgment "0"
and receives a following 8-bit write data. After receipt of write data, the EEPROM outputs
acknowledgment "0". If the EEPROM receives a stop condition, the EEPROM enters an internally-timed
write cycle and terminates receipt of SCL, SDA inputs until completion of the write cycle. The EEPROM
returns to a standby mode after completion of the write cycle.
