DESCRIPTION

CPU Supervisor with 32Kb 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.

FEATURES

• Selectable watchdog timer

• Low V detection and reset assertion

—Five standard reset threshold voltages

—Re-program 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

• 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

• 32Kbits of EEPROM

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.

• 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

detection circuitry protects the

—In circuit programmable ROM mode

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

• Minimize EEPROM programming time

—32-byte page write mode

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. Five industry stan-

dard V thresholds are available, however, Intersil’s

—Self-timed write cycle

TRIP

—5ms write cycle time (typical)

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

operation

unique circuits allow the threshold to be reprogrammed

to meet custom requirements or to fine-tune the thresh-

old for applications requiring higher precision.

• Available packages

—14 Ld TSSOP, 8 Ld SOIC, 8 Ld PDIP

• Pb-free plus anneal available (RoHS compliant)
