DSPIC33EP32GS202T-I/SS - 70MIPS 16-bit DSC 32KB Flash | Microchip
The Microchip Technology DSPIC33EP32GS202T-I/SS is a 16-bit digital signal controller (DSC) delivering 70 MIPS performance with 32KB (32K x 8) of Flash memory, packaged in a 28-pin SSOP (5.30mm width) surface-mount body and optimized specifically for digital power applications. A digital signal controller combines the computational throughput of a DSP core with the deterministic behavior and peripheral set of a microcontroller. Within the power-management hierarchy, a DSC sits between a general-purpose MCU and a dedicated power-supply IC: it runs closed-loop control firmware for switch-mode converters while integrating the analog and timing peripherals that dedicated controllers would normally require as external chips. The GS202 variant of the dsPIC33EP family differentiates itself with a dual high-speed 12-bit ADC architecture supporting on-chip analog programmable gain amplifiers (PGA), multiple high-speed analog comparators, and a dedicated high-resolution PWM module designed for switching power stages. These peripherals enable cycle-accurate control of converters switching at hundreds of kilohertz, with the ADC triggered directly from the PWM engine for minimal control-loop latency. The dsPIC33EP core operates from a 3.0V to 3.6V supply and reaches its full 70 MIPS rate from a single-cycle DSP multiply-accumulate engine, hardware division support, and zero-overhead looping, all of which are essential for executing Proportional-Integral-Derivative (PID) and predictive control algorithms inside tight switching periods. Typical applications include AC-DC power factor correction (PFC) stages, DC-DC converters, digital lighting ballasts, battery chargers, and uninterruptible power supplies. Microchip's Interleaved PFC reference design based on this family operates from universal AC input and produces up to 350W of regulated DC output. Designers should budget for the 3.3V-only supply range and reserve the VCAP pin decoupling per datasheet guidance; firmware portability across the dsPIC33EP family allows reuse of control code when moving between package or memory variants.
