DESCRIPTION

CPU Supervisor with 32Kbit SPI EEPROM

These devices combine three popular functions, Power-

on Reset Control, 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

• 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

• Long battery life with low power consumption

—<1µA max standby current

—<400µA max active current during read

• 32Kbits of EEPROM

The device’s low V

detection circuitry protects the

• Built-in inadvertent write protection

—Power-up/power-down protection circuitry

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

user’s system from low voltage conditions by holding

RESET/RESET active when V falls below a mini-

mum V trip point. RESET/RESET remains asserted

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

• Minimize EEPROM programming time

—32-byte page write mode

lizes. Five industry standard V

thresholds are

available, however, Intersil’s unique circuits allow the

threshold to be reprogrammed to meet custom

requirements or to fine-tune the threshold in applica-

tions requiring higher precision.

—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 plus anneal available (RoHS compliant)
