CAT1321 - (CAT1320 / CAT1321) Supervisory Circuits

Download the CAT1321 datasheet PDF. This datasheet also covers the CAT1320 variant, as both devices belong to the same (cat1320 / cat1321) supervisory circuits family and are provided as variant models within a single manufacturer datasheet.

Description

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.
