Note: The write cycle time t
WR
is the time from a valid stop condition of a write sequence to the end of the valid start
condition of sequential command.

· Sequential read
Sequential reads are initiated by either a current ad-
dress read or a random address read. After the
microcontroller receives a data word, it responds with an
acknowledgment. As long as the EEPROM receives an
acknowledgment, 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
continues. The sequential read operation is terminated
when the microcontroller does not respond with a zero
but generates a following stop condition (refer to Se-
quential read timing).
