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.
R < 40 k
is recommended to make sure
that voltage drop across R does not violate
the device’s electrical specification.
R1 = 100

will limit any current
flowing into MCLR from external capacitor
