Cover story
2. Double-Precision Floating-Point Unit (DP-FPU): This unit is IEEE 754-2019 compliant, supporting single and double precision with a dedicated pipeline, improving software reliability and control loop speed while reducing software errors associated with variable scaling. It includes hardware-based sine and cosine functions for better motor control.
3. Enhanced DSP Engine and CPU: Features two 72-bit accumulators for high resolution and accuracy, minimising the risk of overfl ows or underfl ows.
4. Advanced High-Speed Peripherals: Includes a 12-bit ADC with 40 MSPS, Operational Amplifi ers with 100 MHz gain– bandwidth product (GBW) and fast comparators with 5 ns response time.
5. Enhanced Security Features and Memory Architecture: Security is bolstered with an Immutable Root of Trust, secure debug and Flash segment access restriction.
First Product in dsPIC33A DSC Family The fi rst family of dsPIC33AK128MC1xx DSCs will include 128KB Flash and an extensive peripheral set and will be offered in various packages, including SSOP, VQFN and TQFP options ranging from 28 to 64 pins, with package dimensions as small as at 4x4 mm. Future dsPIC33A families with additional memory, peripherals and larger pin counts will complete the portfolio.
Ecosystem and Support To accelerate the design process, Microchip offers a comprehensive ecosystem of motor control software
and hardware development tools. The dsPIC33CK Motor Control Starter Kit (MCSK) and the MCLV-48V- 300W Development Board are new dsPIC33-based motor driver boards along with several integrated motor driver based development boards that facilitate rapid prototyping of motor control applications. The MPLAB motorBench Development Suite, a complimentary GUI- based tool for FOC, measures motor parameters, tunes feedback control gains and generates source code. Version 2.45 introduces Zero-Speed/Maximum Torque (ZS/MT), maximising torque output without Hall or magnetic sensors. Microchip also provides complimentary MPLAB
Device Blocks for MATLAB Simulink, enabling optimised code generation for dsPIC DSCs and other Microchip MCUs. The expanding portfolio includes ready-to- use several motor control reference designs targeted for automotive, e-mobility, industrial and consumer applications. The new dsPIC33A series streamlines embedded
system development with model-based design and an Instruction Set Architecture (ISA) compatible with existing dsPIC33 DSCs. It integrates with MPLAB XC-DSC Compiler and MPLAB Code Configurator, supported by the dsPIC33A Curiosity Development Board (EV74H48A) for general purpose use with dsPIC33AK128MC106 Motor Control DIM (EV68M17A). The ecosystem is expanding to enhance support for model-based design, motor control, DSP algorithms, advanced sensing, digital power and functional safety.
