dsPIC33EV ‘GM’ Family of Digital Signal Controllers

5V Robust Designs | Motor Control | High-Performance Embedded | Measurement Control | CAN | Functional Safety

Automotive and industrial embedded applications must operate reliably in extreme or challenging environmental conditions. Applications such as automotive sensors or CNC machinery need to be able to withstand a variety of harsh conditions including noise and vibration. Offering 5V and up to 150°C operation, the dsPIC33EV ‘GM’ family of Digital Signal Controllers (DSCs) offers high noise immunity and can meet a wide range of requirements to help you create a robust design.

Combining the performance of a Digital Signal Processor (DSP) engine and versatile peripherals of a microcontroller, the dsPIC33EV ‘GM’ DSCs are ideal for high-performance embedded and motor control applications. Featuring an advanced Analog-to-Digital Converter (ADC) and op amps, these DSCs are ideal for sensor interfacing and signal conditioning applications. Their high level of analog integration reduces your Bill of Materials (BoM) cost and design form factor.

The robust dsPIC33EV ‘GM’ DSCs feature dedicated peripherals and functions to help increase the reliability in safety-critical applications. These features facilitate to ensure end applications operate as intended, with safe shut down if any exception or issue occurs. With AEC Q100 Grade 0 qualification, these DSCs are ideal for automotive applications.
