Industrial Control and Driver Solutions
PIC microcontrollers and dsPIC controllers contain innovative motor control PWM peripherals including complimentary waveforms and dedicated time-base. For applications that require variable speed with constant torque and field oriented control for greater efficiency, the high performance dsPIC core includes DSP instructions for more precise control.
The single-chip motor control and motor drive solutions enable simpler designs and decrease board space and are often used as companion chips with PIC microcontrollers for stepper motors.

The 6-pin products of the PIC10F family offer the motor control designer an opportunity to use microcontrollers in applications that have historically been void of such devices. Whether it is cost or space constraints, PIC10F microcontrollers address these concerns by providing a pricing structure that makes them nearly disposable with form factors that can easily be implemented into the most space constrained designs. The ADC, comparator and timer peripherals found in the PIC10F device family can be used to provide a user interface for basic on/off control, speed control and other intelligent motor functions.
Features:
- Up to 2 MIPS execution
- x3 DFN or 6-pin SOT-23 package
- Internal oscillator
- Comparator
- Internal 8-bit ADC
The PIC12F and PIC16F product families have an 8-bit CPU that can operate at speeds up to 5 MIPS. Device variants in the PIC12F family have 8 pins, while PIC16F variants are offered in 14-pin through 64-pin packages. Some variants in the PIC16F family have one or more Enhanced Capture Compare PWM Peripheral (ECCP) modules. The ECCP module is optimized for controlling 1/2 bridge or H-bridge motor drive circuits. It can also be used to steer PWM control signals among 4 output pins for BLDC motor commutation or stepper motor control.
Features:
- 4 ch. PWM 10-bit
- 256 bytes of EEPROM data memory
- Extended WDT
- MPLAB® ICD 3 programming support or debugging support with optional header adapter
- Precision internal oscillator-software selectable 8 MHz-32 KHz
- nanoWatt Technology
- Software selectable BOR
The PIC18F product family also has an 8-bit CPU and offers extended performance over the PIC16F device family. The PIC18F device family can operate at speeds up to 12 MIPS and has a hardware multiplier for faster calculation of control algorithms. There are variants in the PIC18F family with specialized motor control peripherals, including a 3-phase motor control PWM peripheral and a quadrature encoder interface (QEI). Other PIC18F variants have the ECCP module found on the PIC16F device family. Source code developed for the PIC16F device family can be easily migrated to the PIC18F family. Devices with the motor control PWM module are well suited for variable speed 3-phase motor applications, while devices with the ECCP module are useful for brush DC and stepper motor applications.
Features:
- Up to 12 MIPS execution speed with H/W multiplier
- Motor control PWM module with up to 8 outputs
- One or more ECCP modules
- 8- or 10-bit ADC (with up to 200 ksps sample rate on (PIC18F)
