R1EX24064ASA00A Datasheet, PDF (17/22 Pages) Renesas Technology Corp – Two-wire serial interface 64k EEPROM (8-kword × 8-bit)

R1EX24064Axx00A
Sequential Read:
Sequential reads are initiated by either a current address read or a random read. If the EEPROM receives
acknowledgment “0” after 8-bit read data, the read address is incremented and the next 8-bit read data are
coming out. This operation can be continued as long as the EEPROM receives acknowledgment “0”. The
address will roll over and returns address zero if it reaches the last address of the last page. The sequential
read can be continued after roll over. The sequential read is terminated if the EEPROM receives
acknowledgment “1” (no acknowledgment) and a following stop condition.
