CPU Supervisor with 4K SPI EEPROM

DESCRIPTION

FEATURES

• Selectable time out watchdog timer

• Low V detection and reset assertion

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.

—Five standard reset threshold voltages

—Re-program low V reset threshold voltage

using special programming sequence.

—Reset signal valid to V = 1V

• Long battery life with low power consumption

—<50µA max standby current, watchdog on

—<10µA max standby current, watchdog off

—<2mA max active current during read

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

versions

• 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

• 3.3MHz clock rate

• Minimize programming time

—16-byte page write mode

—Self-timed write cycle

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 oscil-

lator to stabilize before the processor executes code.

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.

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

—5ms write cycle time (typical)

• SPI modes (0,0 & 1,1)

• Available packages

—8-lead MSOP, 8-lead SOIC, 8-pin PDIP

—14-lead TSSOP

to proper operating level and stabilizes. Five industry

standard V thresholds are available, however,

TRIP

Xicor’s unique circuits allow the threshold to be repro-

grammed to meet custom requirements or to ﬁne-tune

the threshold for applications requiring higher precision.
