Motor Control | Dual CAN | USB Connectivity | Speech and Audio | High-Pin Count Options


Motors can be found in a wide range of applications and end markets. In most of these designs, it is essential that they run efficiently and consume as little power as possible. dsPIC33EP ‘MU’ family of Digital Signal Controllers (DSCs) offers 70 MIPS performance, a Digital Signal Processing (DSP) engine and specialized motor control peripherals that enable you to implement high-efficiency, high-precision, variable-speed, constant-torque Proportional Integrated (PI) control and Field Oriented Control (FOC) in your design for higher energy efficiency and quieter operation.

The dsPIC33EP ‘MU’ family is ideal for controlling a variety of motors, including stepper motors, Brushless DC (BLDC) motors, Permanent Magnet Synchronous Motors (PMSMs), AC Induction Motors (ACIMs) and Switched Reluctance Motors (SRMs). The dsPIC33EP ‘MU’ DSCs feature two master time base modules to control dual 3-phase motors simultaneously, a high-speed Analog-to-Digital Converter (ADC), op amps and comparators to optimize your 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 ‘MU’ family of DSCs can facilitate a robust motor control design capable of withstanding harsh environments found in industrial and automotive applications.

The dsPIC33EP ‘MU’ family also features large pin-count options with packages up to 144 pins, large Flash memories of up to 512 KB and 52 KB of SRAM, making these DSCs excellent solutions for high-end embedded applications, such as multi-sensor control systems and speech/audio products. The large RAM enables these DSCs to run complex filtering software that requires large data buffers, making them well suited for speech recognition, noise and echo cancellation applications. Free DSP filter software, noise suppression and echo cancellation libraries are provided to speed your design development. In addition, the dsPIC33EP 'MU' family also features a Full Speed USB host and device and a high-speed Direct Memory Access (DMA) controller to enable easy connectivity to external systems and PCs.
