FN8126.1

CPU Supervisor with 4K SPI EEPROM

Features

• Low V_CCDetection and Reset Assertion

- Four standard reset threshold voltages

4.63V, 4.38V, 2.93V, 2.63V

- Re-program low V_CCreset threshold voltage using

special programming sequence.

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.

- Reset signal valid to V_CC= 1V

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.

• Selectable Time Out Watchdog Timer

• Long Battery Life with Low Power Consumption

- <50µA max standby current, watchdog on

- <10µA max standby current, watchdog off

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.

• 4Kbits of EEPROM–1M Write Cycle Endurance

• Save Critical Data with Block Lock^™Memory

- Protect 1/4, 1/2, all or none of EEPROM array

• Built-in Inadvertent Write Protection

- Write enable latch

- Write protect pin

The device’s low V_CCdetection circuitry protects the user’s

system from low voltage conditions, resetting the system

when V_CCfalls below the minimum V_CCtrip point.

RESET/RESET is asserted until V_CCreturns 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.

• SPI Interface - 3.3MHz Clock Rate

• Minimize Programming Time

- 16-byte page write mode

- 5ms write cycle time (typical)

• Available Packages

- 8 Ld MSOP, 8 Ld SOIC, 8 Ld PDIP

- 14 Ld TSSOP

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.

• Pb-Free Plus Anneal Available (RoHS Compliant)

Applications

• Communications Equipment

- Routers, Hubs, Switches

- Set Top Boxes

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.

• Industrial Systems

- Process Control

- Intelligent Instrumentation

• Computer Systems

- Desktop Computers

- Network Servers

• Battery Powered Equipment

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
