X5328/X5329

CPU Supervisor with 32Kbit SPI EEPROM

FEATURES

DESCRIPTION

• Low V detection and reset assertion

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.

—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

—<1µA max standby current, watchdog off

—<400µA max active current during read

• 32Kbits of EEPROM

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.

• 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

—In circuit programmable ROM mode

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

• Minimize EEPROM programming time

—32-byte page write mode

The device’s low V

user’s system from low voltage conditions by holding

RESET/RESET active when V falls below a mini-

detection circuitry protects the

mum V

until V

trip point. RESET/RESET remains asserted

returns to proper operating level and stabi-

lizes. Five industry standard V

thresholds are

TRIP

available, however, Xicor’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-lead TSSOP, 8-lead SOIC
