R1EX24008ASA00A Datasheet, PDF (17/22 Pages) Renesas Technology Corp – Two-wire serial interface 8k EEPROM (1-kword × 8-bit)

R1EX24008Axx00A
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.
