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.
