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

Download the X5329 datasheet PDF. This datasheet also covers the X5328 variant, as both devices belong to the same (x5328 / x5329) cpu supervisor with 32kbit spi eeprom family and are provided as variant models within a single manufacturer datasheet.

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.
