CAT1161 Datasheet (ON Semiconductor) - Precision Reset Controller and Watchdog Timer

CAT1161, Precision Reset Controller and Watchdog Timer

The CAT1161/2 is a complete memory and supervisory solution for microcontroller *based systems.

A serial EEPROM memory (16K) with hardware memory write protection, a system power supervisor with brown out protection and a watchdog timer are integrated together in low power CMOS technology.

CAT1161 Features

* a 16

* byte page. In addition, hardware data protection is provided by a write protect pin WP and by a VCC sense circuit that prevents writes to memory whenever VCC falls below the reset threshold or until VCC reaches the reset threshold during power up. Available packages include an 8
