DSPIC33FJ64MC202-E/SP - 16-bit DSC 64KB Flash 40MIPS | Microchip

The Microchip Technology DSPIC33FJ64MC202-E/SP is a 16-bit digital signal controller (DSC) delivering 40 MIPS from 64KB (64K x 8) of Flash memory, housed in a 28-pin SPDIP through-hole package and rated for -40C to +125C operation at 3V to 3.6V supply. A digital signal controller combines the computational architecture of a digital signal processor with the peripheral set and ease of use of a microcontroller. In the product hierarchy, the DSC sits between a general-purpose MCU and a dedicated DSP: it executes high-speed, repetitive multiply-accumulate loops for control mathematics while integrating motor-control PWM, high-speed ADC, and DMA peripherals on one chip. The dsPIC33F family from Microchip Technology is pin compatible with the PIC24HJ family, giving designers a migration path between general-purpose and DSP-centric pinouts. Key features of the DSPIC33FJ64MC202-E/SP include the 16-bit modified Harvard dsPIC core clocked at up to 40 MIPS, 64KB Flash program memory with self-programming capability, motor-control PWM modules targeted at three-phase and BLDC drives, a direct memory access (DMA) controller that offloads ADC and UART data transfers from the CPU, and advanced analog peripherals for current and voltage sensing. The -E extended temperature grade (-40C to +125C) supports industrial and automotive-adjacent environments. Technically, the 16-bit RISC architecture uses two 40-bit accumulators and hardware DSP multiply-accumulate instructions, enabling single-cycle MAC operations for FOC (field-oriented control), PID loops, and digital filtering. The wide 28-pin SPDIP package suits breadboarding, prototyping, education, and legacy through-hole production where hand soldering and socketing matter. Typical applications include brushless DC and permanent-magnet motor control, digital power supplies and PFC stages, sensor signal conditioning with on-chip filtering, and industrial instrumentation requiring deterministic 40 MIPS control loops. Design consideration: the dsPIC33F core requires a VCAP/VDDCORE capacitor on the internal regulator output pin, and the supply must remain within 3.0V-3.6V; the on-board regulator simplifies 3.3V rail design but this capacitor must never be omitted.
