X5045 - CPU Supervisor with 4K SPI EEPROM

Download the X5045 datasheet PDF. This datasheet also covers the X50 variant, as both devices belong to the same cpu supervisor with 4k spi eeprom family and are provided as variant models within a single manufacturer datasheet.

General Description

These devices combine four popular functions, Poweron Reset Control, Watchdog Timer, 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.

Key Features

  • Selectable time out watchdog timer.
  • 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.
