General Description

The X40620 combines several functions into one device.

The first is a dual voltage monitoring, power-on reset control, watchdog timer and 64Kbit serial BLOCK DIAGRAM WP Write Control Logic HV Gener

Overview

64K X40620 Dual Voltage CPU Supervisor with 64K Serial EEPROM EEPROM memory in one package.

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

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

Key Features

  • Dual Voltage Detection and Reset Assertion.
  • Three standard reset threshold settings. (3.1V/ 2.6V, 3.1V/1.7V, 2.9V/2.3V).
  • Adjust low voltage reset threshold voltages using special programming sequence.
  • RESET signal valid down to VCC=1V.
  • Watchdog Timer (150ms).
  • Power On Reset (150ms).
  • Low Power CMOS.
  • 10µA typical standby current, watchdog on.
  • 400µA typical standby current, watchdog off.
  • 64kbit 2-Wire Serial EEPRO.
