DESCRIPTION
The X40020 combines power-on reset control, watch-
dog 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 to V CC activates the power-on reset
circuit which holds RESET/RESET active for a period of
time. This allows the power supply and system oscilla-
tor to stabilize before the processor can execute code.
