4.1 Basic Connection Requirements

Getting started with the PIC18-Q83 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:

These pins must also be connected if they are being used in the end application:

Additionally, the following pins may be required:

  • VREF+/VREF- pins are used when external voltage reference for analog modules is implemented

The minimum mandatory connections are shown in the figure below.
