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

BOARD USER’S GUIDE
Chapter 1. Overview
1.1
INTRODUCTION
The Digital Power Development Board is a demonstration board that provides the user
with a flexible measurement platform for all compatible Microchip dsPIC33 Digital
Power Plug-In Modules (DP PIMs). DP PIMs can be inserted into the mating socket J1
in the middle of the Digital Power Development Board. All pins of the DP PIM are
accessible via test loops or pin headers. The on-board micro USB connector provides
a DC power input to all circuitry. In addition, a mikroBUS™ socket is provided to extend
functionality.
This chapter provides an overview of the features of the Digital Power Development
Board. The topics covered include:
• Features
• Electrical Characteristics
1.2

1.2.1
Socket for DP PIM Boards
Insert the DP PIM board under test into the socket located in the middle of the Digital
Power Development Board. Socket J1 has a slot that defines the DP PIM board
direction. Be careful not to break the slot when inserting the DP PIM board into
the socket.
1.2.2
Test Points
The Digital Power Development Board ensures good signal integrity and provides
access to all pins of a DP PIM board. Each signal line is named after the DP PIM edge
connector pin number, with a “TP” (Test Point) prefix on the schematic diagram, which
is similarly marked on the silkscreen. These signals are divided into two main sections:
Analog and Digital (see Figure 1-1). For a detailed pinout, refer to the User’s Guide of
the DP PIM under test.
1. Analog Section
The analog section is located at the left connector side (smaller sector of the
socket). It consists of 18 signal lines, all referenced to analog ground. These lines
are split into two subsections:
• ADC inputs
• DAC output
2. Digital Section
The digital section is located at the right connector side (larger sector of the
socket). It consists of 31 lines, all referenced to digital ground. These lines
support all the digital lines of the DP PIMs. Some of them have dedicated
functions, such as:
• High-speed PWM outputs
• Medium speed GPIO
• Communication lines (SPI, I2C, UART)
• User push button and LEDs

Overview
1.2.3
Grounding System
The entire board ground potential is connected together and forms one galvanically
common domain. The labels, “Analog” and “Digital”, indicate the geometrical domain.
The copper pour connected to the ground potential is split into two geometrical
domains, but the two geometrical domains are jointed together under the PIM socket,
thus improving the signal integrity and keeping noise confined to near their sources.
1.2.4
External Analog Signal Input
It is possible to insert an analog signal to any ADC input from a signal generator via a
standard BNC connector. The input impedance is 50. Input signals between the
ground and +3.3V are accepted. An overvoltage protection is implemented on this input
with a series resistor, and a pair of parallel diodes between the ground and the positive
supply rail.
1.2.5
DC Level Insertion
Two on-board potentiometers are connected between the ground and the +3.3V supply
rail to provide two stable DC levels. The two DC levels can be set independently with
potentiometers: P1 and P2. These DC signals can be used as an input signal to any
ADC input. The DC level set by P1 can be connected to the upper half, while P2 can
be connected to the lower half of the ADC inputs, at the analog input connection
jumpers.
1.2.6
Analog Input Connection Jumpers
The ADC inputs of the DP PIM board can be accessed directly from the pin header (J3)
located at the left side of the board. These inputs can also be connected to either the
external analog signal input (J7) or to the DC level insertion, respectively. The
three-row pin header matrix, J4, J5, J6 (No. 7 in Figure 1-1), forms a three-pin selection
jumper for each ADC input. When placing a jumper over the left, or over the right and
the middle pins, the corresponding ADC input can be connected to the extra input as
indicated on the silkscreen. The left side pins connect the external analog signal input,
while the right side pins connect the DC level insertion to the given ADC input. Two
positions on the DAC outputs are not connected. The pins on those positions are just
placeholders to keep the pin order. Three pins are connected to GND at both ends of
the jumper row. Jumpers can be stored on those pins if not needed. Two jumpers are
provided in the kit.
1.2.7
Push Buttons
There are two push buttons on the board: SW1 and SW2. Push button SW2, which is
directly connected to the RESET pin of the DP PIM board, is for the system Reset. For
dual core devices, this RESET is connected to the Master core Reset line. Push button
SW1 is a general purpose user interface connected to the TP27 test point and the
corresponding pin on the DP PIM.
1.2.8
MikroBUS™ Socket
A standard extension socket (J10) is provided on the board for mikroBUS
click boards™. The functionality of the board can be easily extended by using this
feature. The DP PIM board communicates with the mikroBUS socket via dedicated SPI
lines and the I2C bus. Both +5V and +3.3V supply rails are connected to the
corresponding pins of the mikroBUS socket. The Reset button is connected to the
mikroBUS socket RESET pin.

DS50002814A-page 11
Digital Power Development Board User’s Guide
1.2.9
ICSP™ Programming Port
Dedicated lines for programming the MCU device on the inserted DP PIM board are
accessible via an RJ-25 modular connector or on a 6-pin header.
1.2.10
General Purpose Soldering Pad Area
The soldering point matrix on the bottom of the board with Plated-Through-Hole (PTH)
pads can be used to assemble any small extension circuitry needed for testing or
prototyping.
1.2.11
Solder Pad for Ground Connection
A bare gold-plated copper area is located on the upper and the bottom edges of the
board. These areas can either be used for soldering a solid ground connection or for
attaching alligator clips to connect instrument ground.
1.2.12
USB Connector
The Digital Power Development Board can be powered via the micro USB connector,
J2, at the right side of the board. The DP PIM board supply input and the +5V power
rail for the mikroBUS click board are directly connected to the positive supply line of the
USB. This connector is only for powering. The input voltage must be in the range of
3.6V to 6.3V. The mikroBUS click board can tighten this constraint; please refer to the
specifications before powering. Communication is not possible via this USB connector.
1.2.13
On-Board LDO
The +3.3V power rail for the mikroBUS click board is supplied by the on-board LDO
(Microchip’s MCP1755), connected to the +5V supply rail coming from the USB. The
total load for the mikroBUS click board supply current and the additional load caused
by its active GPIO lines should not exceed 300 mA. The DC level insertion
potentiometer and the pull-up resistor of the user push button are also connected to this
line. The Power Good output drives the Reset line of the board, ensuring stable
performance.
1.2.14
Power Indicator LED
The green LED (LD1) is on when the supply voltage is applied on the +5V supply rail.
1.2.15
User LEDs
The Digital Power Development Board has two user-programmable on-board LEDs.
The red LED is connected to TP52, while the green LED is connected to TP54. Logic
level high drives the LEDs.
