X5083 Datasheet CPU Supervisor

Manufacturer: Intersil (now Renesas)

Overview

® X5083 Data Sheet June 15, 2006 FN8127.3 CPU Supervisor with 8Kbit SPI EEPROM This device combines four popular functions, Power-on Reset Control, Watchdog Timer, Supply Voltage Supervision, and Block Lock Serial EEPROM Memory in one package.

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

Applying power to the device activates the power-on reset circuit which holds RESET active for a period of time.

Key Features

  • Low VCC detection and reset assertion - Four standard reset threshold voltages 4.63V, 4.38V, 2.93V, 2.63V - Re-program low VCC reset threshold voltage using special programming sequence - Reset signal valid to VCC = 1V.
  • Selectable time out watchdog timer.
  • Long battery life with low power consumption -.
