X4165 - CPU Supervisor

Download the X4165 datasheet PDF. This datasheet also covers the X4163 variant, as both devices belong to the same cpu supervisor family and are provided as variant models within a single manufacturer datasheet.

Description

The X4163/5 combines four popular functions, Poweron 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.
