Digital signal controllers provide fast and robust platform for motor control or power conversion

The dsPIC33C digital signal controllers from Microchip combine fast DSP functionality with microcontroller features and analog peripherals, to enable implementation of complete motor- or power-system designs with a single chip.

The Microchip dsPIC33C family of digital signal controllers (DSCs) provides an ideal combination of high digital signal processor (DSP) performance with a microcontroller-like peripheral set for use in motor and power-conversion applications that require high performance and robustness.

Offering 100 MIPS performance, the dsPIC33C family of DSCs provides a path for users of dsPIC33E and dsPIC33F DSCs to develop more sophisticated applications. These DSCs feature the dsPIC33 C core with a DSP engine, expanded context-selected registers to reduce interrupt latency, new instructions to accelerate DSP performance, tightly coupled peripherals, and faster execution to enable complex, high-speed control loop implementation.

The dsPIC33C DSCs are ideal for the control of many types of motors, including brushless DC, permanent magnet synchronous motors, ac induction, switched reluctance and stepper motors. The DSCs’ high level of peripheral integration enables applications to implement power factor correction and motor control with a single chip.

Loaded with intelligent analog peripherals, the dsPIC33C family also provides easy-to-use smart sensor interfaces for various sensing applications.

The dsPIC33 DSCs feature a DSP engine for the high-speed execution of control loops. Key features include:

Dual, independent cores in the dsPIC33CH series, to enable the system to isolate time-critical control loops from housekeeping functions
High-speed ADCs, programmable gain amplifiers and a CPU with fast and predictable interrupts
PWM controllers operating at a resolution of up to 250 ps, giving the flexibility to control numerous power topologies

In addition, the dsPIC33C MPT series features an integrated hardware security module providing various security functions including:

  • Immutable secure boot
  • Secure firmware upgrade with live update
  • Secure on-board communication and message authentication
  • Electronic control unit (ECU) authentication
