CAT1026 Datasheet (Catalyst Semiconductor) - Dual Voltage Supervisory Circuits

CAT1026, Dual Voltage Supervisory Circuits

The CAT1026 and CAT1027 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.

The
