N84C163
Supervisory Circuits with EEPROM Serial 16-Kb I2C Precision Reset Controller and Watchdog Timer (16K)
Description
The N84C163 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 N84C163 watchdog monitors the WDI input pin.
The power supply monitor and reset circuit protects memory and system ...
