Microchip Expands dsPIC33A DSC Family for High-Density AI Data Center Power, Complex Motor Control and Intelligent Sensing

As AI servers, data centers, automotive and industrial systems demand higher efficiency designs, deterministic real-time control and quantum-resistant cryptography, Microchip Technology has added dsPIC33AK256MPS306 Digital Signal Controllers (DSCs) to its dsPIC33A DSC family. The dsPIC33AK256MPS306 devices combine high-resolution control, high-speed analog and security with support for post-quantum cryptography. The devices are compact and cost-effective, designed to reduce the bill of materials (BOM), simplify board layout and accelerate time to market for power conversion, motor control and intelligent sensing applications.

Built on a 200 MHz 32-bit core with a double-precision floating point unit (FPU), the dsPIC33AK256MPS306 family integrates high-resolution 78 ps Pulse Width Modulators (PWMs), multiple 40 MSPS 12-bit Analog-to-Digital Converters (ADCs), 5 ns high-speed comparators and Digital-to-Analog Converters (DACs) with slope compensation. These features help enable fast, deterministic control loops for high-efficiency DC/DC converters, auxiliary power rails and intelligent sensing designs, including systems based on Silicon Carbide (SiC) and Gallium Nitride (GaN) power semiconductors operating at high switching frequencies (more info).
