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 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 —Self-timed write cycle —5ms write cycle time (typical)
● 2.7V to 5.5V and 4.5V to 5.5V power supply operati
