BOARD USER’S GUIDE
Chapter 2. Hardware Overview
This chapter describes the hardware components of the dsPICDEM MCLV-2
Development Board. Topics covered include:
• PIM Configuration
• Board Connectors
• User Interface Hardware
Power for the control circuits and DC bus on the board is provided through a +24V
power supply attached to the Power Connector terminal (J2) or the Auxiliary Power Tab
Fast-On Connector terminals (BP1-BP2). The Microchip 24V Power Supply
(AC002013) is recommended.
The various components on the board receive power as follows:
•
•
•
•
The Gate drivers receive +15V power from a 15V regulator
The CAN driver receives +5V power from a 5V regulator
The LIN driver receives VBAT power from the LIN connector J1.
A dsPIC DSC or PIC24 MCU motor control device receives +3.3V power from a
+3.3V regulator
• The RS-232 UART interface receives +3.3V power from a +3.3V regulator
• The PIC18LF2450 USB to UART Bridge receives +3.3V power from a +3.3V
regulator
Note 1:
2:
If the input voltage value is less than 16V, remove the 15V voltage
regulator and short jumper J3.
To use a higher DC voltage bus (24V-48V), complete the following steps:
a) Connect the power supply to jumper J7, and keep jumper J6 open.
b) Power the circuit components, MCU, and the gate drivers using a
separate 16V-24V power supply connected to the power connector
J2 or BP1-BP2.

Hardware Overview
2.2.1
Input Power Connector (J2, BP1-BP2)
The dsPICDEM MCLV-2 Development Board receives the power for control circuits
and the DC bus from a +24V power supply. It is connected to the board through J2 or
BP1-BP2 points.
2.2.2
DC Bus Power Supply Connector (J6 and J7)
By default, jumper J6 is short, and the +24V input power supply connected to J2 or
BP1-BP2 supplies the DC bus voltage to the board.
2.2.3
CAN Interface (J4)
The board has a MCP2551 High-Speed CAN Transceiver, which is connected to the
dsPIC DSC or PIC24 MCU through jumpers JP4 and JP5. The CAN transceiver
converts the differential signal on the CAN bus to a digital signal for the ECAN™ module. It also converts the ECAN output digital signal to a differential signal for the CAN
bus. In Sleep mode, the CAN transmitter is turned off, and the receiver operates at a
lower current level. The control device monitors the CAN activity and switches the
transceiver back to normal operation when needed. For more information, refer to the
data sheet, MCP2551 “High-Speed CAN Transceiver” (DS21667).
2.2.4
LIN Interface (J1)
The board has a MCP2021 High-Speed LIN Transceiver, which is connected to the
dsPIC DSC or PIC24 MCU through jumpers JP4 and JP5. The LIN transceiver
monitors the LIN bus, conditions the incoming signal, and passes it to the UART module on the control device. The LIN transceiver responds to a “Transmit Enable” from the
control device by conditioning an output signal and placing it on the LIN bus. A
power-down mode turns the transmitter and voltage regulator off, leaving only the
receiver and wake-up circuits in operation. The LIN circuit includes a Master/Slave
jumper to accommodate a Master node on the LIN bus. For more information, refer to
the data sheet, MCP202X “LIN Transceiver with Voltage Regulator” (DS22018).
2.2.5
USB Interface (J8)
The board uses an on-board PIC18 interface as a bridge between the UART and USB.
The PIC18 UART pins are connected to the dsPIC DSC or PIC24 MCU through
jumpers JP4 and JP5.
2.2.6
ICD 3 Connector (J11- J12)
The ICD 3 connector is an RJ11 female connector (J11) that connects the MPLAB
ICD 3 In-Circuit Debugger/Emulator to the dsPIC DSC or PIC24 MCU for programming
and debugging purposes. The ICD 3 can also be connected to the board using 6-pin
ICSP connector (J12).
2.2.7
ICSP for PIC18 (J9)
The jumper J9 is a 6-pin connector that connects the PICkit™ 3 development
programmer to the PIC18F device. The board uses the on-board PIC18 interface as a
bridge between the UART and USB. The PIC18F is programmed for USB
communication.
2.2.8
RS-232 Connector (J10)
The connector J10 is an RS-232 interface port. The board uses the UART connector
to pass the UART signals from the dsPIC DSC or PIC24 MCU to the dedicated UART
IC MAX3232CUE. The output of U14 is provided to the connector J10.

The Matrix Board Interface
The matrix board interface facilitates the following functions:
• Connects the appropriate signals to the correct pins on the Plug-In Module (PIM)
• Disconnects signals and provides isolation on signal paths that, in a particular
hardware configuration, are not being used
The matrix board header has two rows of pins. One row (pins 1-25) hosts signals from
different signal sources, the other (pins 26-50) hosts connections to the PIM. Figure 2-2
is a block diagram that describes the matrix board interface.

2.2.10.1
INTERNAL AND EXTERNAL OP AMP MATRIX BOARDS
The dsPICDEM MCLV-2 Development Board uses discrete op amps (U5) to amplify the
shunt resistor signals. Alternatively, some PIC24 MCUs or dsPIC DSCs are designed
with op amps on-board that can be used for this purpose. To accommodate these two
basic configurations, the dsPICDEM MCLV-2 Development Board includes two matrix
boards.
• The Internal Op Amp Configuration Matrix Board configures the development
board to use op amps that are internal to the PIC24 MCU or dsPIC DSC. This
matrix board bypasses the current feedback circuitry on the dsPICDEM MCLV-2
Development Board and directly connects the shunt resistor signals to appropriate
pins of the PIM.
• The External Op Amp Configuration Matrix Board configures the development
board to use the current feedback circuitry on the dsPICDEM MCLV-2 Development Board. This matrix board disconnects the shunt resistor signals from the PIM
pins and connects the current feedback circuitry output to the appropriate PIM
pins.
Note:
2012 Microchip Technology Inc.
Unless specified in the PIM information sheet, all PIMs are compatible only
with the External Op amp Configuration matrix board. Certain PIMs are
designed to work only with the Internal Op amp Configuration matrix
boards. In this case, the corresponding PIM information sheet (available at
www.microchip.com/pims) will explicitly state this.
