FIGURE 8-14: EXTERNAL POWER-ON
RESET CIRCUIT (FOR SLOW
V
DD
POWER-UP)
Note 1: External Power-on Reset circuit is
required only if V
DD
power-up slope is too
slow. The diode D helps discharge the
capacitor quickly when V
DD
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
pin break-
down due to Electrostatic Discharge
(ESD) or Electrical Overstress (EOS).

FIGURE 8-16: EXTERNAL BROWN-OUT
PROTECTION CIRCUIT 2
Note 1: This circuit will activate reset when V
DD
goes below (Vz + 0.7V) where Vz = Zener
voltage.
2: Internal brown-out detection on the
PIC16C710/711/715 should be disabled
when using this circuit.
3: Resistors should be adjusted for the char-
acteristics of the transistor.

Note 1: This brown-out circuit is less expensive,
albeit less accurate. Transistor Q1 turns
off when V

is below a certain level
such that:

2: Internal brown-out detection on the
PIC16C710/711/715 should be disabled
when using this circuit.
3: Resistors should be adjusted for the
characteristics of the transistor.
