Discover Microchip’s Comprehensive Motor Control Solutions Mixed-Signal Power Torque Speed Input Direction Position 8-bit PIC® Microcontroller or 16-bit dsPIC® Digital Signal Controller Feedback MOSFET or IGBT Driver Why chose Microchip for your next motor control design? Our 8-bit Microcontrollers and 16-bit Digital Signal Controllers contain innovative on-chip peripherals designed specifically for motor control.
Which MCU or DSC Should You Choose? Microchip provides many devices that can be used in motor control applications. PIC12F and PIC16F Microcontroller Product Family Microchip makes many families of MCUs and DSCs, including 8-, 16- and 32-bit solutions. All of these can be used in motor control applications. However, some families contain special motor control peripherals and features as described below.
16-bit Product Family with Advanced Peripherals Advanced Motor Control often does not require DSP but benefits greatly from the DSP resources found on the dsPIC® Digital Signal Controllers (DSCs). For example, our sensorless field-oriented control algorithm makes use of the single cycle MAC with data saturation, zero overhead looping and barrel shifting to achieve stunning performance.
Advanced Motor Control Applications Are you considering moving to brushless motors or sinusoidal control, eliminating costly sensors or adding PFC? Let Microchip show you how to save energy, reduce noise and cost, improve torque response and reliability.

Development Systems Microchip offers a number of development boards and advanced development tools that demonstrate the capabilities of its motor control silicon solutions. These tools work with Microchip’s MPLAB® ICD 2 In-Circuit Debugger (DV164005) to download, program and debug application software. Our systems make it easy to customize the software for specific motors.
Motor Control Tuning GUIs These software plug-in tools included with MPLAB®IDE assist with the development of motor control applications: ■ AN901 BLDC Tuning Interface – Provides a graphical method to configure the motor parameters associated with the AN901 application. ■ AN908 ACIM Tuning Interface – Provides a graphical method to adjust the control loop parameters associated with the AN908 application.
