New dsPIC33A Digital Signal Controllers Designed for Improved Precision and Real-Time Control

31 July 2024 - 0 Comments

Microchip Technology has introduced the dsPIC33A Core family of Digital Signal Controllers (DSCs), equipped for handling complex embedded control algorithms in motor control, power supply, charging, and sensing systems. These controllers feature a 32-bit CPU operating at 200 MHz, a Double-Precision Floating-Point Unit, and DSP instructions for precise real-time control. They offer enhanced math and data processing, higher code efficiency, faster context switching, and reduced latency, ensuring quick response times to critical events. Additionally, the controllers include new high-resolution PWMs for motor control and digital power conversion, targeting markets such as automotive, industrial, consumer, E-Mobility, data center, and sustainable solutions.

The dsPIC33A family integrates 12-bit ADCs (up to 40 Msps), high-speed comparators, and operational amplifiers for advanced sensing and control. Core Independent Peripherals (CIPs) enable peripheral interaction without CPU involvement, optimizing task management and preserving CPU bandwidth for software, safety diagnostics, and security functions.

Security features include Flash security, an Immutable Root of Trust, secure debugging, and restricted memory access. The Instruction Set Architecture (ISA) supports model-based code generation. The dsPIC33A DSCs are suitable for applications in motor control, digital power conversion, and sensor interfacing within industrial and automotive sectors.
