dsPIC33EP ‘MC’ Family of Digital Signal Controllers

Motor Control | Real-Time Control | Dual CAN | Functional Safety | Scalable

Electric motors are everywhere, spanning across industrial, automotive, consumer and medical applications. Since these electric motors are an integral part of many electrical devices and consume the most power, minimizing the power consumed by motors is an essential design consideration. Microchip’s dsPIC33EP ‘MC’ family offers 70 MIPS performance, a Digital Signal Processing (DSP) engine and specialized peripherals that can be used to implement high-efficiency, high-precision, variable-speed, constant-torque Proportional Integral (PI) control and Field Oriented Control (FOC) of motors.

The dsPIC33EP ‘MC’ family is ideal for controlling Permanent Magnet Synchronous Motors (PMSMs), AC Induction Motors (ACIMs) and Brushless DC (BLDC) motors. Combining the performance of a DSP engine and the simplicity of a microcontroller, the dsPIC33EP ‘MC’ DSCs feature three pairs of motor control Pulse-Width Modulators (PWMs), a high-speed Analog-to-Digital Converter (ADC), op amps and comparators for an optimized design. The high-level of analog integration reduces your Bill of Materials (BoM) cost and design form factor. Offering up to 150°C operation, the dsPIC33EP ‘MC’ family of DSCs can facilitate a robust motor control design that is able to withstand harsh environments.

These robust DSCs feature dedicated peripherals and functions to help increase reliability in safety-critical applications to ensure that your end applications operate as intended, with safe shut down if any exception or issue arises. These AEC Q100 Grade 0 qualified DSCs are also excellent options for automotive applications.
