CAT1024 Datasheet (Catalyst Semiconductor)

CAT1024, Supervisory Circuits

The CAT1024 and CAT1025 are complete memory and supervisory solutions for microcontroller-based systems.

A 2k-bit serial EEPROM memory and a system power supervisor with brown-out protection are integrated together in low power CMOS techno * logy.

Memory interface is via a 400kHz I2C bus.
