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.
SOIC−8 CASE 751BD
TSSOP−8 CASE 948S
The CAT1021 and CAT1023 provide a precision VCC sense circuit
and two open drain outputs: one (RESET) drives high and the other
(RESET) drives low whenever VCC falls below the reset threshold
voltage.
The CAT1022 h...
