Write Operations(WP=High)
Byte Write: (Write operation during WP=High status)
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 16kbit EEPROM receives 8-bit memory
address words.
Upon receipt of this memory address, the EEPROM outputs acknowledgment "0". After receipt of 8-bit
write data, the EEPROM outputs acknowledgment "1"(NO ACK). Then the EEPROM write operations
are not allowed.
