Description	CPU Supervisor with 4K SPI EEPROM
Datasheet	X5043 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.

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

Overview

4K X5043/X5045 CPU Supervisor with 4K SPI EEPROM 512 x 8 Bit.

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.
