Datasheet Summary

Description

VBAT VCCO VCC GND PF RVT OSCIN OSCSEL IN NMI ST CEO CEI WDS RST RST - +3-Volt Battery Input - Switched SRAM Supply Output - +5-Volt Power Supply Input - Ground - Power-Fail - Reset Voltage Threshold - Oscillator In - Oscillator Select - Early Warning Input - Non-Maskable Interrupt - Strobe Input

Features

  • Holds microprocessor in check during power transients Halts and restarts an out-of-control microprocessor Warns microprocessor of an impending power failure Converts CMOS SRAM into nonvolatile memory Unconditionally write protects memory when power supply is out of tolerance Delays write protection until completion of the current memory cycle Consumes less than 200 nA of battery current Controls external power switch for high current.
