dsPIC33EV256GM106 5V Motor Control Plug-In Module (PIM) Information Sheet

The dsPIC33EV256GM106 5V Motor Control PIM is designed to demonstrate the capabilities of the dsPIC33EV256GM106 motor control device, using both internal and external op amps with the Low-Voltage Motor Control Development Bundle (DV330100), by using its 105-pin interface.

The dsPIC33EV256GM106 device is a high-performance, 16-bit Digital Signal Controller (DSC) in a 64-pin TQFP package. This PIM is designed to take advantage of all the features of the device, such as the four internal op amps/comparators, the additional dedicated comparator, the ADC Converter and the dedicated motor control PWM unit (3 PWM generators).

The dsPIC33EV256GM106 5V Motor Control PIM takes advantage of these analog peripherals, config-ured using on-board passive components (resistors and capacitors) to support motor control applica-tions. The PIM is designed to enable driving one motor with both internal and external op amps.

In order to operate this device with the Low-Voltage Motor Control Development Bundle, please insert the dsPIC33EV256GM106 5V Motor Control PIM on the dsPIC® DSC Signal Board. Table 1 provides informa-tion on the hardware versions of the motor control boards that are compatible with this PIM. Refer to the user’s guide for the specific motor control board for hardware version identification information.

Connector J1 interacts with the Signal Board to have the correct power supply voltage generated. The Signal Board is, in fact, capable of generating both 3.3V and 5V. For a correct voltage to be supplied to the dsPIC33EV256GM106, resistors R33 and R34must always be populated with 0 Ohm value resistors.

Four different voltage references, from PIM:101 to PIM:104 are used to bias each of the four op amps present on the device. Each op amp reference volt-age is independent from the others, allowing a large versatility in the hardware configuration.

Op Amp 1, as seen in Figure 4, is not used by default. This means that if the filter, bias and feedback circuit will be populated and configured by software, it can be used as a general purpose op amp. The positive input will be

PIM:38, the negative input is PIM:39 and the output is PIM:19. All of these three signals are routed to Connector C on the Signal Board for easy prototyping.

Prototyping Area

This area is located on the upper side of the dsPIC33EV256GM106 5V Motor Control PIM (see Figure 5).

TP1 to TP10 and C25 to C30 are pads and holes avail-able for further enhancement and prototyping directly on the PIM. The right pads (marked with red) are internally

connected to Analog Ground (AGND). The rest of the pads are connected only to the nearest test point. With this configuration, extra SMD resistors or capacitors can be added to the circuit by soldering them on the pads, and then soldering wires from the test points to the place on the PIM where the added components are needed.

Note the following details of the code protection feature on Microchip devices:

• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of ourproducts. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such actsallow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
