X5083

CPU Supervisor with 8Kbit SPI EEPROM

FEATURES

• Low VCC detection and reset assertion

—Four standard reset threshold voltages

4.63V, 4.38V, 2.93V, 2.63V

—Re-program low VCC reset threshold voltage

using special programming sequence.

—Reset signal valid to VCC = 1V

• Selectable time out watchdog timer

• 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

• 8Kbits of EEPROM

• Save critical data with Block Lock™ memory

—Block lock first or last page, any 1/4 or lower 1/2

of EEPROM array

• Built-in inadvertent write protection

—Write enable latch

—Write protect pin

• SPI Interface - 3.3MHz clock rate

• Minimize programming time

—16 byte page write mode

—5ms write cycle time (typical)

• SPI modes (0,0 & 1,1)

• Available packages

—8-lead TSSOP, 8-lead SOIC, 8-Lead PDIP

APPLICATIONS
