DSPIC33CK64MP202T-I/2N Overview
A digital signal controller combines the computational throughput of a digital signal processor with the deterministic control architecture and peripheral set of a microcontroller. Within the power management hierarchy, a DSC sits between a general-purpose MCU and a dedicated DSP, providing single-cycle MAC (multiply-accumulate) DSP instructions alongside real-time control peripherals. The dsPIC33CK family belongs to Microchip's 16-bit dsPIC33C product line, which targets closed-loop control systems such as digital power conversion, motor control, and advanced sensing.
Key features of the DSPIC33CK64MP202T-I/2N include a 100 MHz core executing from dual-panel FLASH for zero-wait-state execution, 64KB of self-programmable FLASH supporting field firmware updates, and 8KB of on-chip RAM for control-loop state variables. The Mouser listing highlights integrated operational amplifiers (OpAmps), 12-bit ADCs, and PWM peripherals, which allow the device to condition sensor signals, sample them at high speed, and generate high-resolution PWM outputs in a single closed-loop pass.
Architecturally, the dsPIC33C core integrates enhanced DSP capability and enhanced on-chip peripherals designed for digital power, motor control, advanced sensing and control, and high-performance general-purpose applications. DigiKey also classifies the device as a Functional Safety (FuSa) capable part within the dsPIC 33CK family, which supports safety-oriented designs requiring documented development support.
Typical applications include AC-DC and DC-DC digital power supplies, brushless DC (BLDC) and PMSM motor drives, power-factor-correction stages, and battery charging systems. The integrated op-amps and 12-bit ADCs eliminate external signal-conditioning components, while the high-resolution PWM enables fine duty-cycle and phase control required in LLC and totem-pole topologies.
When designing with this part, budget the exposed-pad UQFN package for thermal relief through a grounded copper pour, and verify supply decoupling on the 3.3V rail per the manufacturer datasheet. Confirm pin-multiplexing choices early, since 28-pin devices share many peripheral functions per pin.

Typical Applications
DSPIC33CK64MP202T-I/2N is suitable for 6 applications: Digital Power Supplies (AC-DC / DC-DC), BLDC and PMSM Motor Control, Power Factor Correction (PFC), Battery Charging Systems, Advanced Sensing and Control Nodes, Industrial Automation and Control Panels.
Digital Power Supplies (AC-DC / DC-DC)
The DSPIC33CK64MP202T-I/2N fits digital power conversion because its 100 MHz dsPIC33CK core executes single-cycle MAC instructions, sustaining control-loop update rates required by LLC, buck, boost, and PFC stages. The on-chip 12-bit ADCs sample output voltage and inductor current, while the high-resolution PWM provides the fine duty-cycle resolution needed for tight regulation and soft switching. Because the part integrates op-amps, current-shunt signals can be amplified internally, removing external signal-conditioning ICs and reducing BOM cost in a 28-pin 6x6 mm UQFN footprint. In a typical topology, the DSC sits between the feedback divider and the power-stage gate drivers, closing the voltage loop entirely in firmware; the trade-off versus an analog controller is firmware complexity, offset by full flexibility of control-law tuning and telemetry.
Recommended
BLDC and PMSM Motor Control
Motor drives demand fast, deterministic current loops, and the DSPIC33CK64MP202T-I/2N delivers this with its 100 MHz core, integrated op-amps, 12-bit ADCs, and PWM peripherals. A typical field-oriented-control (FOC) implementation uses the on-chip op-amps to amplify low-side shunt voltages, the ADCs to trigger simultaneous phase-current sampling at the PWM center, and the PWM module to drive a three-phase inverter through gate drivers. The 8KB of RAM holds the Clarke/Park transforms and PI state variables without external memory, and the 64KB dual-panel FLASH allows firmware execution with no stall while supporting field updates. Microchip explicitly targets the dsPIC33CK family at motor control; the industrial -40C to +125C operating grade suits appliance, industrial-drive, and e-mobility environments.
Recommended
Power Factor Correction (PFC)
In totem-pole or boost PFC stages, the DSPIC33CK64MP202T-I/2N provides the fast inner current loop and slower outer voltage loop that PFC control requires. The high-resolution PWM enables the sub-nanosecond duty-cycle adjustments needed for zero-voltage-switching transitions in totem-pole topologies, while the 12-bit ADCs capture AC input current and rectified bus voltage each switching cycle at the 100 MHz core's pace. The integrated op-amps condition current-transformer or shunt signals directly, and DSP MAC instructions execute the control-law arithmetic in a handful of cycles. Designers should account for ADC-to-PWM latency and use the exposed-pad UQFN package with a solid ground pour to keep switching noise out of the analog front end, per Microchip digital-power reference designs for the dsPIC33CK family.
Recommended
Battery Charging Systems
Smart battery chargers need multi-phase control (pre-charge, constant current, constant voltage, termination) plus safety supervision, which maps well to the DSPIC33CK64MP202T-I/2N. The 12-bit ADCs monitor charge current, pack voltage, and temperature through the integrated op-amp front ends, while the high-resolution PWM drives the buck or buck-boost charging power stage with the resolution needed for accurate CC-CV regulation at the 100 MHz core's loop rate. The 64KB dual-panel FLASH stores charging profiles and supports field firmware updates for new chemistry profiles, and the industrial temperature grade covers -40C to +125C environments. Firmware-based control also simplifies compliance with charger safety sequencing requirements, since watchdog and fault-handling logic can be tailored per application.
Recommended
Advanced Sensing and Control Nodes
The DSPIC33CK64MP202T-I/2N serves as an intelligent sensing node where analog signals must be conditioned, digitized, and processed locally. Its integrated op-amps buffer sensor outputs, the 12-bit ADCs digitize them, and the DSP instructions run filtering and compensation math at 100 MHz - a complete analog-to-decision chain in one 3.3V device. DigiKey's Functional Safety (FuSa) classification for the dsPIC 33CK family supports deployment in control systems where documented development processes matter, such as industrial automation and safety-related sensing. The 28-pin UQFN 6x6 mm footprint suits compact distributed nodes, and the 64KB FLASH accommodates protocol stacks for field connectivity. Designers should verify peripheral-to-pin multiplexing early, since 28-pin devices share many functions per pin.
Recommended
Industrial Automation and Control Panels
Industrial control applications benefit from the DSPIC33CK64MP202T-I/2N's combination of DSP throughput, robust peripherals, and -40C to +125C industrial temperature rating. Typical roles include actuator control, closed-loop process trimming, and local sequencing logic inside larger automation systems. The 100 MHz core with dual-panel FLASH provides deterministic real-time response, the PWM and ADC peripherals handle motorized actuators and analog instrumentation, and the FuSa-capable dsPIC 33CK classification supports documented safety processes used in factory equipment. With 64KB of FLASH and 8KB of RAM, the device runs moderate control firmware including communication parsing. Distributed boards around the plant can share one DSC platform, reducing firmware reuse cost across the product line.

Design Notes
The 28-UQFN 6x6 mm package has an exposed pad on the underside that must be soldered to a grounded copper pour. This pad provides both the primary ground connection and heat dissipation path. Use an array of thermal vias (typically 4-9) connecting the pad to internal ground planes. Follow the Microchip-recommended UQFN land pattern; undersized stencil apertures (around 50-70% coverage) with paste-dividing patterns reduce voiding under the exposed pad during reflow.
The device operates from a 3.3V supply. Place 100 nF ceramic decoupling capacitors as close as possible to each VDD/AVDD pin pair, plus one bulk capacitor (4.7-10 uF) near the part. The dsPIC33C core requires the VCAP stabilization capacitor specified in the manufacturer datasheet - omitting it or using the wrong value can prevent startup or cause erratic resets. Keep the analog supply (AVDD) filtered or fed from a clean LDO rail when using the ADCs and op-amps in noise-sensitive digital power loops.
On 28-pin devices, many peripheral functions are multiplexed onto shared pins via the Peripheral Pin Select (PPS) mechanism. Map your PWM outputs, ADC inputs, and communication pins early in schematic capture - conflicts discovered at PCB layout stage often force respins. In digital power and motor-control layouts, keep high-current PWM/gate-driver loops physically separated from the op-amp and ADC input traces, and return high currents to the exposed-pad ground rather than through signal ground traces.
Verify peripheral availability per exact part number before committing a design: the dsPIC33CK family datasheet covers 28/36/48/64/80-pin parts, and not every module (e.g., CAN FD) is present on every 28-pin variant. Also note the T suffix denotes tape-and-reel for automated assembly - for hand-placement prototypes, the tube variant (DSPIC33CK64MP202-I/2N) is more convenient. Programming uses the ICSP interface (PGD/PGC) via tools such as PICkit or ICD; reserve these pins as header access in your layout.
