Note the following details of the code protection feature on Microchip devices:

• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

of the cable into the USB connector on the starter kit board.

Check the board: the green power LED D3 should be lit. If it is not, check the
connections at the port, hub and board.

2.2.4 Install the USB Device Driver

Note: The USB driver installation steps described here refer specifically to

installing the driver on a Microsoft Windows XP operating system.

Perform the following steps to install the USB device driver:

2.3 USING THE STARTER KIT OUT OF THE BOX

Install the software before connecting the board to the host PC. The starter kit may be
used directly from the box as a demonstration board for the PIC32 device. The PIC32
is preprogrammed with the classic “Simon Says” game (
PIC32 device and is ready for immediate use.

2.3.1 How to Play the Game

When the USB debug cable is plugged into the starter kit’s Mini-B (debug) receptacle,
the three LEDs start blinking to indicate the start of a new game. Begin the game by
pressing one of the switches, SW1-SW3, to choose the level of game difficulty. SW3 is
the easiest, SW1 is the hardest. The goal is to imitate the light patterns as long as you
can without getting frazzled. Ultimately , you will make a mistake and all of the LEDs will
light up to signal the end of the game. After a brief pause, you can press any switch to
start a new game.

If you launch MPLAB IDE and connect to the starter kit while the game is running, the
game will stop. Further, if you perform a debug or program operation from MPLAB IDE,
the demo application will be replaced with the current MPLAB project application.
However, the game can be reloaded onto the starter kit by importing the file,

simon_says_demo.mcw, from the following location:

[install directory]\PIC32 Starter Kits\simon_says_demo

The preprogrammed example code on the PIC32 device has been included in the
starter kit demo-projects download file, which is available from the Microchip web site
(www.microchip.com). All project files have been included, so that the code may be
used directly to restore a PIC32 device to its original state (i.e., if the sample device has
been reprogrammed with another program), or so you can use the tutorial code as a
platform for further experimentation.

Chapter 5. Hardware

This chapter describes the hardware features of the starter kit.

5.1 HARDWARE FEATURES

5.1.1 PIC32 (General Purpose) Starter Kit

The key features of the PIC32 Starter Kit are listed below. They are presented in the
order given in Section 1.2 “PIC32 Functionality and Features”. You can refer to
Figure 1-1 for their locations on the board.

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

PIC32MX360F512L processor.

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

PIC32 STARTER KIT

USER’S GUIDE

• 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.

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

intended to be USB bus powered.

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

5.1.1.3 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.

5.1.1.4 SWITCHES
Push-butt on 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.

 2010 Microchip Technology Inc. DS61159A-page 47

PIC32 Starter Kit User’s Guide

5.1.1.5 LEDS

The LEDs, RD0 through RD2, are connected to PORTD of the processor. The PORTD
pins are set high to light the LEDs.

5.1.1.6 OSCILLATOR OPTIONS

The installed microcontroller has an oscillator circuit connected to it. The main oscillator
uses an 8 MHz crystal (Y2) and functions as the controller’s primary oscillator. Use of
an external crystal is not required for PIC32 designs. Your design may use the internal
oscillator, if desired.

The PIC18LF4550, at the heart of the USB subsystem, is independently clocked and
has its own 8 MHz crystal (Y1).

5.1.1.7 120-PIN MODULAR EXPANSION CONNECTOR

The PIC32 Starter Kit demo board has been designed with a 120-pin modular expan­sion interface, which allows the board to provide basic generic functionality now, as well
as easy extendability to new technologies as they become available.

5.1.2 PIC32 USB Starter Kit II

The key features of the PIC32 USB Starter Kit II are listed below. They are presented
in the orde r gi ven in Sec tion 1.2 “PIC32 Functionality and Features”. You can refer
to Figure 1-2 for their locations on the board.

5.1.2.1 PROCESSOR SUPPORT
The PIC32 USB Starter Kit II is designed with a permanently mounted (i.e., soldered)

PIC32MX795F512L processor.

5.1.2.2 POWER SUPPLY
There are two ways to supply power to the PIC32 USB Starter Kit II:

• USB bus power connected to USB debug connector 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.

5.1.2.3 DEBUG USB CONNECTIVITY
The PIC32 USB Starter Kit II includes a PIC32MX440F512H USB microcontroller that

provides debugger connectivity over USB. The PIC32MX440F512H is hard wired to the
PIC32 device to provide two types of protocol translation:

• I/O pins of PIC32MX440F512H to the ICSP™ pins of the PIC32

• I/O pins of PIC32MX440F512H to the JTAG pins of the PIC32
The PIC32 USB Starter Kit II currently uses the JTAG pins of the PIC32 device for

programming and debugging.

5.1.2.4 PIC32 USB CONNECTIVITY
There are three possible ways to connect to the PIC32 USB microcontroller:

• HOST Mode

Connect the device to the Type A connector J4, located on the top side of the
starter kit. If using the Debug USB port to power the Host port, install jumper JP2
to short the back-power prevention diode. Note that a maximum of ~400 mA can
be supplied from the Debug USB port to the Host port using this method.

If the full 500 mA supply is needed, an external supply must be connected to the
application board and jumper JP2 must be removed to prevent back-powering the
Debug USB port.

• DEVICE Mode

First, connect the debug Mini-B USB cable to port J1. Next, connect the starter kit
to the host using a cable with a Type-B Micro plug to the starter kit’s Micro A/B
port J5, located on the bottom side of the starter kit. The other end of the cable

5.1.2.5 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 software debounce techniques. When idle, the
switches are pulled high (+3.3V). When pressed, they are grounded.

5.1.2.6 LEDS

The RD0 through RD2 LEDs are connected to PORTD of the processor. The PORTD
pins are set high to light the LEDs.

5.1.2.7 OSCILLATOR OPTIONS

The installed microcontroller has an oscillator circuit connected to it. The main oscillator
uses an 8 MHz crystal (Y2) and functions as the controller’s primary oscillator. Use of
an external crystal is required to develop USB applications. The USB specification
dictates a frequency tolerance of +/- 0.25% for full speed. Non-USB applications can
use the internal oscillators. The starter kit also has provisions for an external secondary
oscillator (Y3); however, this is not populated.

The PIC32MX440F512H is independently clocked and has its own 8 MHz crystal (Y1).

5.1.2.8 120-PIN MODULAR EXPANSION CONNECTOR

The PIC32 USB Starter Kit II has been designed with a 120-pin modular expansion
interface, which allows the board to provide basic generic functionality now, and easy
extendability to new technologies as they become available.

5.1.3 PIC32 Ethernet Starter Kit

The key features of the PIC32 Ethernet Starter Kit are listed below. They are presented
in the orde r gi ven in Sec tion 1.2 “PIC32 Functionality and Features”. You can refer
to Figure 1-4 for their locations on the board.

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

PIC32MX795F512L processor.

5.1.3.2 POWER SUPPLY
There are two ways to supply power to the PIC32 Ethernet Starter Kit:

• USB bus power connected to USB debug connector 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.

5.1.3.3 DEBUG USB CONNECTIVITY
The PIC32 Ethernet Starter Kit includes a PIC32MX440F512H USB microcontroller

that provides debugger connectivity over USB. The PIC32MX440F512H is hard-wired
to the PIC32 device to provide two types of protocol translation:

• I/O pins of PIC32MX440F512H to the ICSP™ pins of the PIC32

• I/O pins of PIC32MX440F512H to the JTAG pins of the PIC32
The PIC32 Ethernet Starter Kit currently uses the JTAG pins of the PIC32 device for

programming and debugging.

5.1.3.4 PIC32 USB CONNECTIVITY
There are three possible ways to connect to the PIC32 USB microcontroller:

• HOST Mode

Connect the device to the Type A connector J4, located on the top side of the
starter kit. If using the Debug USB port to power the Host port, install jumper JP2
to short the back-power prevention diode. Note that a maximum of ~400 mA can
be supplied from the Debug USB port to the Host port using this method.

If the full 500 mA supply is needed, an external supply must be connected to the
application board and jumper JP2 must be removed to prevent back-powering the
Debug USB port.

• DEVICE Mode

First, connect the debug Mini-B USB cable to port J1. Next, connect the starter kit
to the host using a cable with a Type-B Micro plug to the starter kit’s Micro A/B
port J5, located on the bottom side of the starter kit. The other end of the cable
must have a Type-A plug. Connect it to a USB host. Jumper J2 should be
removed.

• OTG Mode

Connect the starter kit to the OTG device using an OTG Micro A/B cable to the
Micro A/B port J5, located on the bottom side of the starter kit. The starter kit pro­vides an on-board power supply capable of providing 120 mA Max. This supply is
controlled by the PIC32MX795F512L microcontroller. Jumper J2 should be
removed.

The installed microcontroller has an oscillator circuit connected to it. The main oscillator
uses an 8 MHz crystal (Y2) and functions as the controller’s primary oscillator. Use of
an external crystal is required to develop USB applications. The USB specification
dictates a frequency tolerance of +/- 0.25% for full speed. Non-USB applications can
use the internal oscillators. The starter kit also has provisions for an external secondary
32 kHz oscillator (Y3); however, this is not populated. A suitable oscillator, the ECS­3X8, can be obtained from Digi-Key: Part no. X801-ND CMR200TB32.768KDZFTR.

The PIC32MX440F512H is independently clocked and has its own 8 MHz crystal (Y1).

5.1.3.8 120-PIN MODULAR EXPANSION CONNECTOR

The PIC32 Ethernet Starter Kit has been designed with a 120-pin modular expansion
interface, which allows the board to provide basic generic functionality now, and easy
extendability to new technologies as they become available.

5.1.3.9 ETHERNET PHY

The PIC32 Ethernet Starter Kit has been designed with a National DP83848 PHY for
connecting the Starter Kit using an RJ-45 cable to a network. The interface between
the PHY and the PIC32 has been configured for the industry standard RMII interface
and has been isolated from the Modular Expansion Connector. LED D8 indicates the
Ethernet bus speed. When lit, the bus speed is 100 Mb/s; when off, the bus speed is
10 Mb/s.
