1.1 INTRODUCTION

The dsPIC33CH512MP506 Digital Power Plug-In Module (DP PIM) is a demonstration board that, in conjunction with different power boards, showcases the Microchip dsPIC33CH512MP506 16-Bit Digital Signal Controller (DSC) features. The DP PIM provides access to the dsPIC33CH512MP506 analog inputs, the Digital-to-Analog Converter (DAC) output, the Pulse-Width Modulation (PWM) outputs and the General Purpose Input and Output (GPIO) ports.

The series of Microchip DP PIMs feature different device families, from dsPIC33E to dsPIC33CK and dsPIC33CH. These devices have different CPU performance levels as well as peripheral features and functions. However, even if the features and performance levels are different, all DP PIMs have the same functional card edge connector pinout to support seamless migration between device families.

1.2 FEATURES

The dsPIC33CH512MP506 DP PIM has the following features, as shown in Figure 1-1.

Overview

1.2.3 Analog and Digital Signals

The dsPIC33CH512MP506 DP PIM ensures good signal integrity and provides all signals needed to control a power train. These signals are divided into two main sections: Analog and Digital.

1. Analog Section

The analog section is located at the short segment of the edge connector. It consists of 17 signals, all referenced to the analog ground. These lines are split into the following subsections:

• High-Speed Comparator Inputs: RC filtered with corner frequency of 10 MHz and maximum signal rise/fall time of 33 ns. These lines are designed to be used with on-chip comparators for signal tracking tasks, such as peak, valley or zero-cross detections.

• High-Speed ADC Inputs: RC filtered with corner frequency of 2 MHz and maximum signal rise/fall time of 180 ns. These lines are connected to the Track-and-Hold (T&H) circuitry of the dedicated ADC inputs and to the Sample-and-Hold (S&H) circuitry of the shared ADC inputs.

• Medium Speed ADC Inputs: Buffered input lines, RC filtered with corner frequency of 1 MHz and maximum signal rise/fall time of 360 ns.

• Low-Speed ADC Inputs: RC filtered with corner frequency of 190 kHz and maximum signal rise/fall time of 1.8 µs.

• 12-Bit DAC Output with Optional On-Board RC Filtering.

Note: RC filtering and series resistance are needed for good signal integrity, and

for reducing EMI issues. Hence, the board can be used for development purposes under frequent plug-in/out cycles. This decoupling also increases robustness in case of accidental shorts and EMC issues.

2. Digital Section

The digital section is located at the long segment of the edge connector. It consists of 31 signals, all referenced to digital ground. These lines are split into four subsections:

• High-Speed PWM Outputs: Each line has a 75 series resistance.

• Medium Speed GPIO: Each line has a 270 series resistance.

• Programing/Debugging Lines: Each line has a 100 series resistance.

• Communication Lines (SPI): Each line has a 75 series resistance.

Note: The range of the digital I/Os allows access to other peripheral functions of

the populated DSC, such as communication interfaces like I Single-Edge Nibble Transmission (SENT), Controller Area Network (CAN), input capture, output compare, Combinatorial Logic Cells (CLC) and more. Please refer to the device data sheet for further information on available functions.

C, SPI, UART,

1.2.4 dsPIC33CH512MP506 DP PIM – PCB Edge Connector

The dsPIC33CH512MP506 DP PIM has an edge connector compatible with any application board that provides a mating socket.

The mating socket type is Samtec, Inc.: MECF-30-01-L-DV-WT.
