DESCRIPTION

CPU Supervisor with 16K EEPROM

The X4163, X4165 combines four popular functions,

Power-on Reset Control, Watchdog Timer, Supply Volt-

age Supervision, and Serial EEPROM Memory in one

package. This combination lowers system cost,

reduces board space requirements, and increases reli-

ability.

FEATURES

• Selectable watchdog timer

• Low V detection and reset assertion

—Four standard reset threshold voltages

—Adjust low V reset threshold voltage using

special programming sequence

Applying power to the device activates the power on

reset circuit which holds RESET/RESET active for a

period of time. This allows the power supply and oscilla-

tor to stabilize before the processor can execute code.

—Reset signal valid to V = 1V

• Low power CMOS

—<20µA max standby current, watchdog on

—<1µA standby current, watchdog OFF

—3mA active current

• 16Kbits of EEPROM

—64-byte page write mode

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/RESET signal. The user selects the interval

from three preset values. Once selected, the interval

does not change, even after cycling the power.

—Self-timed write cycle

—5ms write cycle time (typical)

• Built-in inadvertent write protection

—Power-up/power-down protection circuitry

—Block Lock (1, 2, 4, 8 pages, all, none)

• 400kHz 2-wire interface

• 2.7V to 5.5V power supply operation

• Available Packages

—8 Ld SOIC

The device’s low V

detection circuitry protects the

user’s system from low voltage conditions, resetting the

system when V falls below the set minimum V trip

point. RESET/RESET is asserted until V

returns to

proper operating level and stabilizes. Four industry

standard V thresholds are available, however, Inter-

—8 Ld TSSOP

• Pb-free plus anneal available (RoHS compliant)

TRIP

sil’s unique circuits allow the threshold to be repro-

grammed to meet custom requirements or to fine-tune

the threshold for applications requiring higher precision.
