64K, 8K x 8 Bit

Data Sheet

March 28, 2005

FN8119.0

PRELIMINARY

• 2.7V to 5.5V power supply operation

• Available Packages

—14-lead SOIC

Dual Voltage CPU Supervisor with 64K

Serial EEPROM

—14-lead TSSOP

FEATURES

• Dual voltage monitoring

DESCRIPTION

—V

operates independent of V

2Mon

The X40626 combines four popular functions, Power-on

Reset Control, Watchdog Timer, Dual Supply Voltage

Supervision, and Serial EEPROM Memory in one pack-

age. This combination lowers system cost, reduces

board space requirements, and increases reliability.

• Watchdog timer with selectable timeout intervals

• Low V detection and reset assertion

—Four standard reset threshold voltages

—User programmable V

threshold

TRIP

—Reset signal valid to V =1V

• Low power CMOS

Applying power to the device activates the power-on

reset circuit which holds RESET active for a period of

time. This allows the power supply and oscillator to stabi-

lize before the processor can execute code.

—20µA max standby current, watchdog on

—1µA standby current, watchdog OFF

• 64Kbits of EEPROM

—64 byte page size

• Built-in inadvertent write protection

—Power-up/power-down protection circuitry

—Protect 0, 1/4, 1/2, all or 64, 128, 256 or 512

bytes of EEPROM array with programmable

Block Lock protection

• 400kHz 2-wire interface

The Watchdog Timer provides an independent protec-

tion mechanism for microcontrollers. When the micro-

controller fails to restart a timer within a selectable time-

out interval, the device activates the RESET signal. The

user selects the interval from three preset values. Once

selected, the interval does not change, even after cycling

the power.

™

—Slave addressing supports up to 4 devices on

the same bus
