X4325 - CPU Supervisor

This page provides the datasheet information for the X4325, a member of the X4323 CPU Supervisor family.

Description

The X4323, X4325 combines four popular functions, Power-on Reset Control, Watchdog Timer, Supply Voltage Supervision, and Serial EEPROM Memory in one package.

This combination lowers system cost, reduces board space requirements, and increases reliability.

Features

  • Selectable watchdog timer.
  • Low VCC detection and reset assertion.
  • Four standard reset threshold voltages.
  • Adjust low VCC reset threshold voltage using special programming sequence.
  • Reset signal valid to VCC = 1V.
  • Low power CMOS.
