Chapter 2. Hardware Overview
This chapter describes the hardware components of the dsPICDEM MCLV
Development Board. Topics covered include:
• PIM Configuration
• Board Connectors
• User Interface Hardware
A +24V power supply connected to the Power Connector terminal (J2) or Auxiliary
Power Tab Fast-On Connector terminals (BP1-BP2) supplies power to the control
circuits and DC bus of the board. It is recommended that you use a 24V power supply
listed as an accessory (Part Number AC002013) on the Microchip web site
(www.microchip.com).
The various components on the board receive the 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 dsPIC33F 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.

Input Power Connector (J2, BP1-BP2)
The dsPICDEM MCLV 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
dsPIC33F device 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).

DS70331A-page 17
dsPICDEMTM MCLV Development Board User’s Guide
2.2.4
LIN Interface (J1)
The board has a MCP2021 High-Speed LIN Transceiver, which is connected to the
dsPIC33F device 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 dsPIC33F device through jumpers JP4 and
JP5.
2.2.6
ICD 2 Connector (J11- J12)
The ICD 2 Connector is an RJ11 female connector (J11) that connects the MPLAB ICD
2 In-Circuit Debugger to the dsPIC33F device for programming and debugging
purposes. The ICD 2 can 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™ 2 development
programmer to the PIC18F device. The board uses the on-board PIC18 interface as a
bridge between the UART and USB. The PIC18F can be 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 dsPIC33F device to the dedicated UART IC
MAX3232CUE. The output of U14 is provided to the connector J10.
2.2.9
Motor Connector (J7)
The motor connector (J7) has 11 terminals. Table 2-6 shows the functionality of each
terminal.

WARNING
Note 1:
The dsPICDEM MCLV Development Board is intended to drive the
three-phase BLDC or PMSM motor. Before connecting the motor, make
sure that the power rating of the motor is equal to or less than the power
rating of the board, as shown in Appendix B. “Electrical
Specifications”. Also, make sure the jumper settings are correct for the
firmware programmed into the target dsPIC DSC device mounted on the
socket. Failure to comply with this warning could lead to malfunction of
the board and the motor, and could result in physical harm.

If the output power exceeds 240W, the power MOSFETs (Q1-Q6) may need
additional heat sink.
By default, the board uses D2-PAK Power MOSFETs. It also supports the TO-220
packages. If the TO-220 Power MOSFETs are used, additional heat sink can be
mounted on the MOSFETs, if required.
