CAT1163 - Precision Reset Controller and Watchdog Timer

Description

The CAT1163 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.

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.
  • pin DIP and a surface mount, 8.
  • pin SO package. http://onsemi. com PDIP.
  • 8 CASE 646AA SOIC.
  • 8 CASE 751BD PIN.

CAT1163 Supervisory Circuits with I2C Serial CMOS EEPROM, Precision Reset Controller and Watchdog Timer (16K) Description The CAT1163 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. Memory interface is via an I2C bus. The 1.6−second watchdog circuit returns a system to a known good state if a software or hardware glitch halts or “hangs” the system. The CAT1163 watchdog monitors the WDI input pin. The power supply monitor and reset circuit protects memory and system controllers during power up/down and against brownout conditions.
