Description

HN58X2432SI, HN58X2464SI are two-wire serial interface EEPROM (Electrically Erasable and

Programmable ROM). They realize high speed, low power consumption and a high level of reliability by

employing advanced MNOS memory technology and CMOS process and low voltage circuitry technology.

They also have a 32-byte page programming function to make their write operation faster.

Note:

Renesas Technology’s serial EEPROM are authorized for using consumer applications such as

cellular phone, camcorders, audio equipment. Therefore, please contact Renesas Technology’s

sales office before using industrial applications such as automotive systems, embedded controllers,

and meters.
