CAT1320 Datasheet (Catalyst Semiconductor) - (CAT1320 / CAT1321) Supervisory Circuits

CAT1320, (CAT1320 / CAT1321) Supervisory Circuits

The CAT1320 and CAT1321 are complete memory and supervisory solutions for microcontroller-based systems.

A 32kbit 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.
