PIC32 STARTER KIT

USER’S GUIDE

Chapter 2. Hardware

This chapter describes the hardware features of the starter kit.

2.1 HARDWARE FEATURES

The key features of the PIC32 Starter Kit are listed below. They are presented in the

order given in Section 1.2 “PIC32 Starter Kit Functionality and Features”. You can

refer to Figure 1-1 for their locations on the board.

2.1.1 Processor Support

The PIC32 Starter Kit is designed with a permanently mounted (i.e., soldered)

PIC32MX360F512L processor.

2.1.2 Power Supply

There are two ways to supply power to the PIC32 Starter Kit:

• USB bus power connected to J1.

• An external application board with a regulated DC power supply that provides +5V

can be connected to the J2 application board connector that is provided on the

bottom side of the board.

One green LED (D3) is provided to show that the PIC32 microcontroller is powered up.

2.1.3 USB Connectivity

The PIC32 Starter Kit includes a PIC18LF4550 USB microcontroller, which provides

both USB connectivity and support for protocol translation. The PIC18LF4550 is

hard-wired to the PIC32MX device to provide two types of connectivity:

• I/O pins of PIC18LF4550 to ICSP™ pins of PIC32MX

• I/O pins of PIC18LF4550 to JTAG pins of PIC32MX

The PIC32MX Starter Kit currently uses the JTAG pins of the PIC32MX device for

programming and debugging.

2.1.4 Switches

Push-button switches provide the following functionality:

• SW1: Active-low switch connected to RD6

• SW2: Active-low switch connected to RD7

• SW3: Active-low switch connected to RD13

The switches do not have any debounce circuitry and require the use of internal pull-

up resistors; this allows you to investigate debounce techniques. When Idle, the

switches are pulled high (+3.3V). When pressed, they are grounded.

Note: The basic PIC32 Starter Kit does not include an application board and is

intended to be USB bus powered.
