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 oscillator
to stabilize before the processor can execute code.
Low VCC detection circuitry protects the user’s system
from low voltage conditions, resetting the system when
VCC falls below the minimum VTRIP1 point. RESET/
RESET is active until VCC returns to proper operating
level and stabilizes. A second voltage monitor circuit
