CAT1321 - (CAT1320 / CAT1321) Supervisory Circuits

This page provides the datasheet information for the CAT1321, a member of the CAT1320 (CAT1320 / CAT1321) Supervisory Circuits family.

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.
