Microchip`s dsPIC33 Digital Signal Controllers for Functional Safety

Implementing advanced motor control often requires a robust solution that offers the performance of a Digital Signal Processor (DSP) engine and the versatile peripherals of a microcontroller. Our dsPIC® Digital Signal Controllers (DSCs) offer key features and specialized peripherals to meet a variety of requirements for high-performance applications.

These applications require safe and reliable operation to protect end-user well-being. Most of the time, electrical systems operate as intended, but in the event of unexpected condition or system malfunction, safety specifications such as ISO 26262, IEC 60730 and IEC 61508 are used to ensure that manufacturers have designed their products to operate safely.

For example, our sensorless Field Oriented Control (FOC) algorithm makes use of a single-cycle MAC with data saturation, zero overhead looping and barrel shifting for exceptional performance. Discover how dsPIC DSCs, along with our ecosystem of development tools, software and other design resources, make it easy to develop your next Brushless DC (BLDC) motor, stepper motor, Permanent Magnet Synchronous Motor (PMSM) or AC Induction Motor (ACIM) application.

High-Performance dsPIC33 DSC Core

  • Up to 100 MIPS with a DSP instruction set and modified Harvard architecture for implementing fast control loops
  • Rich instruction set and addressing modes designed for real-time control where most instructions are single cycle
  • Dual 40-bit accumulators to implement single-cycle MAC instructions
  • Full-speed operation from Flash without added wait states
  • Multiple context registers and accumulators for fast interrupt switching
  • Devices with a dual-core architecture that provides a slave core dedicated for executing time-critical motor control algorithm and a master core dedicated for implementing system monitoring, user interface and communication functions

Target Applications:

  • Motor Control
  • Digital Power Conversion
  • Battery Charging / Charging Station
  • High-End (multi-string) LED Control
  • Applications with hard real time requirements

Functional Safety Ready

Select dsPIC33 DSCs have been designated as “Functional Safety Ready.” A product that contains the “Functional Safety Ready” designation offers integrated hardware safety features, Failure Modes, Effects, and Diagnostic Analysis (FMEDA) reports, safety manuals, and, in some cases, diagnostic software libraries. A TÜV SUD-certified C-compiler and a complete and fully qualified development environment are also available.
