Description
The CAT1021, CAT1022 and CAT1023 are complete memory and supervisory solutions for microcontroller−based systems. A EEPROM Serial 2k−bit I2C memory and a system power supervisor with brown−out protection are integrated together in low power CMOS technology. Memory interface is via a 400 kHz I2C bus.
