• Independent Core Voltage Monitor

Preliminary Datasheet

X40010/X40011/X40014/X40015

Dual Voltage Monitor with Integrated CPU Supervisor

FEATURES

• Industrial Systems

—Process Control

—Intelligent Instrumentation

• Computer Systems

—Computers

• Dual voltage detection and reset assertion

—Standard reset threshold settings

See Selection table on page 2.

—Adjust low voltage reset threshold voltages

using special programming sequence

—Network Servers

—Reset signal valid to V = 1V

DESCRIPTION

—Monitor three voltages or detect power fail

• Independent Core Voltage Monitor (V2MON)

• Fault detection register

• Selectable power on reset timeout (0.05s,

0.2s, 0.4s, 0.8s)

• Selectable watchdog timer interval (25ms, 200ms,

1.4s, off)

• Low power CMOS

The X40010/11/14/15 combines power-on reset con-

trol, watchdog timer, supply voltage supervision, and

secondary voltage supervision, in one package. This

combination lowers system cost, reduces board space

requirements, and increases reliability.

Applying voltage to V

activates the power on reset

circuit which holds RESET/RESET active for a period of

time.This allows the power supply and system oscillator

to stabilize before the processor can execute code.

—25µA typical standby current, watchdog on

—6µA typical standby current, watchdog off

• 400kHz 2-wire interface

• 2.7V to 5.5V power supply operation

• Available packages
