Description

The X40020 combines power-on reset control, watchdog timer, supply voltage supervision, and secondary supervision, and manual reset, in one package. This combination lowers system cost, reduces board space requirements, and increases reliability.

Applying voltage of X40020 to VCC activates the power-on reset circuit which holds RESET/RESET active for a period of time. This allows the power supply and system oscillator to stabilize before the processor can execute code.
