dsPIC30F Device Sockets
The left side of the dsPICDEM 2 Development Board includes sockets (U2B1 and
U2A1) for 28 and 40-pin devices, respectively, in the Motor Control family. The right
side of the board includes sockets (U1C1, U1B1 and U1A1) for 18, 28 and 40-pin
devices, respectively, in the dsPIC30F General Purpose and Sensor family of devices.
These sockets are concentrically arranged headers that allow supported devices in DIP
packages to be plugged directly into the development board.

Oscillators
Device clocking is provided by on-board crystal oscillators. A 7.3728 MHz crystal
oscillator(Y2) provides a system clock for the Motor Control family of devices. Another
7.3728 MHz crystal oscillator (Y5) provides a system clock for the General Purpose and
Sensor family of devices.

Through-holes and pads are provided for a user-furnished watch-type crystal and two
capacitors (Y3 and Y6) connected across pins SOSC1 and SOSC2 on the dsPIC30F
device. Such crystals may be used for real-time clock operation.

Programming/Debugging
An RJ11 header has been provided on the dsPICDEM 2 Development Board in
order to interface with device programmers and debuggers like MPLAB ICD 2
and PRO MATE™ 3. DIP switches in S2, S3 and S4 are provided to connect
the PRO MATE 3 or MPLAB ICD 2 In-Circuit Debugger to the programming and
debugging pins on the installed dsPIC30F device.

and PRO MATE™ 3. DIP switches in S2, S3 and S4 are provided to connect
the PRO MATE 3 or MPLAB ICD 2 In-Circuit Debugger to the programming and
debugging pins on the installed dsPIC30F device.
Switches within S2 should always be used to designate the device being programmed
by MPLAB ICD2. These switches connect the clock and data lines from ICD 2 to the
Programming and Default Debugging channels (PGC/EMUC and PGD/EMUD) on the
dsPIC30F device. In some instances, users may find that their application uses certain
peripherals multiplexed on either the PGC/EMUC or the PGD/EMUD pins. In such
cases, they may avail of alternate debugging channels, EMUC1 & EMUD1 or EMUC2
& EMUD2 or EMUC3 & EMUD3. The dsPICDEM 2 Development Board supports the
