Overview
Replaces X25643/X25645
X5643/X5645
CPU Supervisor with 64Kbit SPI EEPROM
FEATURES
• Selectable watchdog timer • Low VCC detection and reset assertion
—Five standard reset threshold voltages —Re-program low VCC reset threshold voltage
using special programming sequence —Reset signal valid to VCC = 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 • 64Kbits of EEPROM • Built-in inadvertent write protection —Power-up/power-down protection circuitry —Protect 0, 1/4, 1/2 or all of EEPROM array with
