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 DSCs to supply a local
power source. The value of the tank capacitor should
be determined based on the trace resistance that con-
nects the power supply source to the device, and the
maximum current drawn by the device in the applica-
tion. 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.
2.3
A low-ESR (< 5 Ohms) capacitor is required on the
V
voltage regulator output voltage. The V
pin must not be connected to V
capacitor between 4.7 µF and 10 µF, 16V connected to
ground. The type can be ceramic or tantalum. Refer to
Section 25.0
additional information.
The placement of this capacitor should be close to the
V
length not exceed one-quarter inch (6 mm). Refer to
Section 22.2 “On-Chip Voltage Regulator” for
details.

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 the capacitor C, be isolated from
the MCLR pin during programming and debugging
operations.
Place the components shown in Figure 2-2 within
one-quarter inch (6 mm) from the MCLR pin.
