Data Sheet

FN8126.1

CPU Supervisor with 4K SPI EEPROM

These devices combine four popular functions, Power-on

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. This allows the power supply and oscillator to stabilize

before the processor executes code.

The Watchdog Timer provides an independent protection

mechanism for microcontrollers. When the microcontroller

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.

The device’s low V

detection circuitry protects the user’s

system from low voltage conditions, resetting the system

when V

falls below the minimum V

trip point.

RESET/RESET is asserted until V

returns to proper

operating level and stabilizes. Four industry standard V

TRIP

thresholds are available, however, Intersil’s unique circuits

allow the threshold to be reprogrammed to meet custom

requirements or to fine-tune the threshold for applications

requiring higher precision.

The memory portion of the device is a CMOS Serial

EEPROM array with Intersil’s block lock protection. The

array is internally organized as 512 x 8. The device features

a Serial Peripheral Interface (SPI) and software protocol

allowing operation on a simple four-wire bus.

The device utilizes Intersil’s proprietary Direct Write

™

cell,

providing a minimum endurance of 100,000 cycles and a

minimum data retention of 100 years.
