DESCRIPTION
The X40410/11/14/15 combines power-on reset con-
trol, watchdog timer, supply voltage supervision, and
secondary voltage supervision, and Block Lock ? pro-
tect serial EEPROM in one package. This combination
lowers system cost, reduces board space require-
ments, and increases reliability.
Applying voltage 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 oscilla-
