FN8131.2

CPU Supervisor with 32kBit SPI EEPROM

Features

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.

• Selectable watchdog timer

• Low V_CCdetection and reset assertion

- Five standard reset threshold voltages

- Re-program low V_CCreset 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 oscillator to stabilize

before the processor can execute code.

- Reset signal valid to V_CC= 1V

• Determine watchdog or low voltage reset with a volatile

flag bit

• Long battery life with low power consumption

- <50µA max standby current, watchdog on

- <1µA max standby current, watchdog off

- <400µA max active current during read

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.

• 32kbits of EEPROM

• Built-in inadvertent write protection

- Power-up/power-down protection circuitry

- Protect 0, 1/4, 1/2 or all of EEPROM array with Block

Lock^™protection

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. Five 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.

- In circuit programmable ROM mode

• 2MHz SPI interface modes (0,0 and 1,1)

• Minimize EEPROM programming time

- 32-byte page write mode

- Self-timed write cycle

- 5ms write cycle time (typical)

• 2.7V to 5.5V and 4.5V to 5.5V power supply

operation

• Available packages

- 14 Ld TSSOP, 8 Ld SOIC, 8 Ld PDIP

• Pb-free (RoHS compliant)
