DESCRIPTION
The X40420, X40421 combines power-on reset con-
trol, watchdog timer, supply voltage supervision, and
secondary supervision, manual reset, and Block
Lock ? protect serial EEPROM 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.
