2.2.1
The use of a bulk capacitor is recommended to improve
power supply stability. Typical values range from 4.7 µF
to 47 µF. This capacitor should be located as close to
the device as possible.

A low-ESR (1 ohm) capacitor is required on the
V
voltage regulator output. The V
be connected to V
tor, with at least a 6V rating, connected to ground. The
type can be ceramic or tantalum. Refer to

The MCLR pin provides for two specific device
functions:
• Device Reset
• Device programming and debugging
Pulling The MCLR pin low generates a device Reset.

device programming and debugging, the resistance
and capacitance that can be added to the pin must
be considered. Device programmers and debuggers
drive the MCLR pin. Consequently, specific voltage
levels (V
not be adversely affected. Therefore, specific values
of R and C will need to be adjusted based on the
application and PCB requirements.
For example, as illustrated in
recommended that the capacitor C, be isolated from
the MCLR pin during programming and debugging
operations.
Place the components illustrated in
one-quarter inch (6 mm) from the MCLR pin.
