Introduction

The dsPIC33AK256MPS306 Motor Control DIM (P/N: EV22K90A) is designed to demonstrate the motor control capabilities of the dsPIC33AK256MPS306 device. This dsPIC^® DSC features a 200 MHz, single-core Digital Signal Controller (DSC) with a 64-bit floating-point unit (FPU) and enhanced on-chip peripherals.

This motor control DIM is designed to take advantage of the high-speed motor control PWM generators, A/D converters, operational amplifiers, comparators and DACs.

The DIM can be used to demonstrate and develop motor control applications by inserting it in the DIM interface header, provided on the compatible motor control development boards. The DIM is designed to run a single motor with all the compatible development boards. Table 1 provides information on the hardware versions of the motor control development boards that are compatible with this DIM. For additional information regarding development boards, see the respective user’s guide available on the Microchip website (www.microchip.com).

The LED LD1 (green) indicates the power-on status of the DIM. A general purpose LED LD2 (yellow) is provided on the board for debug purposes. The clock for the dsPIC DSC is generated by the MEMS Oscillator (Y1—DSC6011JI2B-008.0000) provided on the DIM. The 8-pin header J2 is provided for interfacing with the programmer/debugger. Any 8-pin, single-row, 0.100 inch (2.54 mm) pitch, unshrouded male header can be used (for example, P/N: 61300811121 from Würth Elektronik).
