N84C161, N84C162 Supervisory Circuits with EEPROM Serial 16-Kb I2C Precision Reset Controller and Watchdog Timer (16K) Description The N84C161/2 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.
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 N84C161 watchdog monitors the SDA line, making an additional PC board trace unnecessary.
The lower cost ...
