DESCRIPTION
The X40010/11/14/15 combines power-on reset con-
trol, watchdog timer, supply voltage supervision, and
secondary voltage supervision, in one package. This
combination lowers system cost, reduces board space
requirements, and increases reliability.
Applying voltage to V
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.
CC
activates the power on reset
Low V
from low voltage conditions, resetting the system when
V
CC
falls below the minimum V
RESET is active until V
CC
returns to proper operating
level and stabilizes. A second voltage monitor circuit
tracks the unregulated supply to provide a power fail
warning or monitors different power supply voltage.
Three common low voltage combinations are avail-
able, however, Xicor’s unique circuits allows the
