CAT1640 Datasheet (ON Semiconductor) - Supervisory Circuits with I2C Serial 64K CMOS EEPROM

CAT1640, Supervisory Circuits with I2C Serial 64K CMOS EEPROM

The CAT1640 and CAT1641 are complete memory and supervisory solutions for microcontroller-based systems.

A 64kbit serial EEPROM memory and a system power supervisor with brown-out protection are integrated together in low power CMOS technology.

Memory interface is via a 400kHz I2C bus.
