Note 1: External Power-on Reset circuit is required
only if V
power-up slope is too slow. The
DD
diode D helps discharge the capacitor
quickly when V
powers down.

2: R < 40 k is recommended to make sure
that voltage drop across R does not violate
the device’s electrical specification.
3: R1 = 100 to 1 k will limit any current
flowing into MCLR from external capacitor
C in the event of MCLR/V
PP
down due to Electrostatic Discharge
(ESD) or Electrical Overstress (EOS).

Note 1: This circuit will activate reset when V
goes below (Vz + 0.7V) where Vz = Zener
voltage.
2: Internal brown-out detection on the
PIC16C72/73A/74A/76/77 should be dis-
abled when using this circuit.
3: Resistors should be adjusted for the char-
acteristics of the transistor.
