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.

2.2
FEATURES
This section describes the key features of the starter kit. Refer to Figure 1-1 and
Figure 1-2 in Chapter 1. “Introduction” for their actual locations on the board.
2.2.1
Processor Support
The dsPIC33E USB Starter Kit is designed with a permanently mounted (i.e., soldered)
dsPIC33EP512MU810 DSC. Similarly, the PIC24E USB Starter Kit is designed with a
permanently mounted (i.e., soldered) PIC24EP512GU810 MCU.
2.2.2
Power Supply
There are two ways to supply power to the dsPIC33E or PIC24E USB Starter Kit:
• Connect the USB Debug connector J2 to a PC running MPLAB using the supplied
mini-B to full-sized A cable
• An external application board with a regulated DC power supply that provides +5V
can be connected to the application board connector (J3) that is provided on the
bottom side of the board
One green LED (D4) is provided to show that the dsPIC33E or PIC24E device is being
powered.
2.2.3
Debug USB Connectivity
The dsPIC33E or PIC24E USB Starter Kit includes a PIC24FJ256GB106 USB microcontroller that provides debugger connectivity over USB. The PIC24FJ256GB106 is
hard-wired to the dsPIC33E or PIC24E device to translate the I/O pins of the
PIC24FJ256GB106 device to the ICSP™ pins of the dsPIC33E or PIC24E device. The
debugger circuit also includes a 25LC256 Serial EEPROM device for data storage.
The programming/debugging circuit on the dsPIC33E or PIC24E USB Starter Kit is similar
in functionality and feature-set to the MPLAB PICkit™ 3 debugger.
2.2.4
dsPIC33E/PIC24E USB Connectivity
There are three possible ways to connect to the dsPIC33E or PIC24E USB
microcontroller:
• Host mode
Connect the device to the type-A connector J6, located on the top side of the
starter kit. If using the debug USB port to power the Host port, install jumper J5 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 for the application, an external supply must be
connected to the application board and jumper J5 must be removed to prevent
back-powering the debug USB port.
• Device mode
First, connect the debug mini-B USB cable to port J2. Next, connect the starter kit
to the USB Host using a cable with a type-B micro plug to the starter kit’s micro-B
port J4, 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 J5 should be
removed.
DS51936B-page 16

Hardware
2.2.5
Switches
Push button switches (SW1, SW2 and SW3) 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 software
debounce techniques. When idle, the switches are pulled high (+3.3V). When pressed,
they are grounded.
2.2.6
LEDs
The LEDs (LED1, LED2 and LED3) are connected to PORT D of the processor:
• LED1: Active-high LED connected to RD0
• LED2: Active-high LED connected to RD1
• LED3: Active-high LED connected to RD2
The corresponding PORT D pins must be configured as digital outputs and set high in
order to turn on the LEDs.
2.2.7
Oscillator Options
The installed DSC or MCU has an 8 MHz crystal (Y3) connected to it. This crystal is
used by the microcontroller’s Primary Oscillator. Use of the external crystal is required
in order to develop USB applications, as the USB specification dictates a frequency tolerance of ± 0.25% for full speed. Non-USB applications can use the internal oscillators
if preferred. The starter kit also has provisions for an external Secondary Oscillator
(Y2); however, the crystal for this oscillator is not populated.
The PIC24FJ256GB106 device is independently clocked and has its own 12 MHz
crystal (Y1).
2.2.8
120-pin Modular Expansion Connector
The dsPIC33E or PIC24E USB Starter Kit includes a 120-pin modular expansion
interface (Application Board Connector J3) on its bottom side. This allows the board to
be optionally used in conjunction with other Microchip development boards such as the
I/O Expansion Board or the Multimedia Expansion Board (MEB), thereby extending the
functionality provided by the starter kit.
