2.2.1
On boards with power traces running longer than six
inches in length, it is suggested to use a tank capacitor
for integrated circuits including microcontrollers to
supply a local power source. The value of the tank
capacitor should be determined based on the trace
resistance that connects the power supply source to
the microcontroller, and the maximum current drawn by
the microcontroller in the application. In other words,
select the tank capacitor so that it meets the acceptable
voltage sag at the device. Typical values range from
4.7 µF to 47 µF.

The MCLR pin provides for two specific device
functions:
• Device Reset
• Device programming and debugging
During 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
transitions must not be adversely affected. Therefore,
specific values of R and C will need to be adjusted
based on the application and PCB requirements.
For
recommended that capacitor C is isolated from the
MCLR pin during programming and debugging
operations.
Place the components shown in
one-quarter inch (6 mm) from the MCLR pin.
