X5328 - (X5328 / X5329) CPU Supervisor with 32Kbit SPI EEPROM

Datasheet Summary

Description

These devices combine three popular functions, Poweron Reset Control, Supply Voltage Supervision, and Block Lock Protect Serial EEPROM Memory in one package.

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

Features

  • Low VCC detection and reset assertion.
  • Five standard reset threshold voltages.
  • Re-program low VCC reset threshold voltage using special programming sequence.
  • Reset signal valid to VCC = 1V.
  • Long battery life with low power consumption.
