The 32-bit dsPIC33A DSC families provide up to 512-KB Flash and a comprehensive set of peripherals, and integrate a double precision floating-point unit to accelerate mathematical computations. The enhanced instruction set and digital signal processing (DSP) capabilities, including single-cycle MAC operations and a 200-MHz core speed, make these devices highly efficient for low-latency, real-time control applications, Microchip said.
Offering advanced features for efficient power conversion, the dsPIC33AK512MPS family delivers precise, high-speed control with 78-ps high-resolution pulse width modulations (PWMs) and low-latency 40 Ms/s ADCs. These features enable fast and accurate control loops, which are essential for optimizing the performance of silicon carbide and gallium nitride-based DC/DC converters, Microchip said.
The dsPIC33AK512MPS devices also include advanced security features, an integrated touch controller, and a high pin count of up to 128 pins. For enhanced system-level security, the dsPIC33AK512MPS family includes integrated crypto accelerators and a Flash security module, enabling immutable root of trust, secure boot, secure firmware upgrades, and secure debug capabilities.
The dsPIC33AK512MC family is designed to offer low-latency, 40 Ms/s ADCs and 1.25-ns PWM resolution. This device is a feature- and cost-optimized solution for multi-motor control and complex embedded applications.
With a range of hardware safety features, dsPIC33AK512MPS/MC DSCs are compliant with functional safety standards and are developed in accordance with International Organization for Standardization (ISO) 26262 and International Electrotechnical Commission (IEC) 61508 processes, making them suitable for safety-critical automotive and industrial applications.
Microchip also offers several development tools including the MPLAB XC-DSC Compiler, MPLAB Code Configurator (MCC), and MPLAB Machine Learning Development Suite. Also available are separate dual in-line modules to support development for motor control, digital power conversion, and general-purpose embedded applications. The DSCs are also supported by partner software and tools including the WHIS SAFERTOS real-time operating and Lauterback TRACE32 debugger.
Prices start at $1.50 each in volume for the dsPIC33AK512MPS/MC DSCs. They can be purchased directly from Microchip or through one of its sales reps or authorized distributors.
