2.1
Getting started with the PIC18F87J90 family family of
8-bit microcontrollers requires attention to a minimal
set of device pin connections before proceeding with
development.
The following pins must always be connected:
• All V
• All AV
• MCLR pin
• ENVREG (if implemented) and V
These pins must also be connected if they are being
used in the end application:
• PGC/PGD pins used for In-Circuit Serial
• OSCI and OSCO pins when an external oscillator
Additionally, the following pins may be required:
• V
The minimum mandatory connections are shown in
Figure 2-1.
