DESCRIPTION
The CAT1021, CAT1022 and CAT1023 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 technology.
Memory interface is via a 400kHz I2C bus.
FEATURES
■ Precision power supply voltage monitor
— 5V, 3.3V and 3V systems
— Five threshold voltage options
■ Watchdog timer
■ Active high or low reset
— Valid reset guaranteed at VCC = 1 V
■ 400kHz I2C bus
■ 3.0V to 5.5V operation
■ Low power CMOS technology
■ 16-Byte page write buffer
■ Built-in inadvertent write protection
— WP pin (CAT1021)
■ 1,000,000 Program/Erase cycles
■ Manual reset input
■ 100 year data retention
■ 8-pin DIP, SOIC, TSSOP, MSOP or TDFN (3 x 3 mm foot-print) packages
— TDFN max height is 0.8mm
■ Industrial and extended temperature ranges
