® X5043, X5045 4K, 512 x 8 Bit Data Sheet March 16, 2006 FN8126.2 CPU Supervisor with 4K SPI EEPROM 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. 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 oscillator to stabilize before the processor executes code. The Watchdog Timer provides an independent protection mechanism for microcontrollers.
