dsPIC33EP ‘GM’ Family of Digital Signal Controllers
Dual Motor Control | High-Performance Embedded | Measurement Control | CAN | Functional Safety
The dsPIC33EP ‘GM’ family of Digital Signal Controllers (DSCs) features a 70 MIPS dsPIC® DSC core with an integrated Digital Signal Processor (DSP) and enhanced on-chip peripherals. These DSCs enable the design of high-performance, precision motor control systems that are more energy efficient, quieter in operation and have a greater range and extended life. They can be used to control brushless DC, permanent magnet synchronous, AC induction and stepper motors. These devices are also ideal for high-performance general-purpose applications.
Microchip offers a wide range of dsPIC33E ‘GM’ DSCs with various levels of peripheral integration for motor control applications. This family of DSCs enables efficient dual-motor control with 12 motor control Pulse-Width Modulation (PWM) channels (six pairs), dual 12-bit Analog-to-Digital Controllers (ADCs), multiple 32-bit quadrature encoder interfaces, and two CAN modules. With this level of integration, the dsPIC33EP512GM710 family can independently control two motors with a single microcontroller (MCU) for optimized system costs. This family can also serve as a communication hub for automotive or industrial applications to connect with multiple CAN buses.
