Xicor X40626
The X40626 combines four popular functions, Power-on Reset Control, Watchdog Timer, Dual Supply Voltage Supervision, and Serial EEPROM Memory in one package. This combination lowers system cost, reduces board space requirements, and increases reliability. This allows the power supply and oscillator to stabilize before the processor can execute code.| Part No. | X40626 |
