DSPIC33CK64MP102T-I/SS Overview
A digital signal controller combines the computational throughput of a digital signal processor with the peripheral integration and deterministic interrupt architecture of a microcontroller. Within the power management hierarchy, the dsPIC33CK family sits between general-purpose MCUs and dedicated digital power ICs, providing a programmable platform for closed-loop control of power conversion stages. The 16-bit pipeline core executes DSP multiply-accumulate instructions, making it well suited to control algorithms that require fast proportional-integral loops and filtering.
Key features of this part include the 100 MHz/100 MIPS single-core CPU, 64 KB of self-programmable Flash with ECC, 8 KB of RAM, a 12-bit high-speed ADC, on-chip operational amplifiers and comparators, multiple PWM modules for power conversion, and Functional Safety (FuSa) support documentation as classified by DigiKey. The I-temperature grade covers -40C to +85C industrial ranges, and the T suffix denotes Tape and Reel packaging for automated assembly.
Architecturally, the dsPIC33CK core adds a zero-overhead DO loop, hardware division support, and a rich interrupt vector table, while the enhanced peripherals target digital power and motor control topologies such as buck, boost, LLC, totem-pole PFC, BLDC, and PMSM drives. The 3.3V supply domain simplifies interface with standard logic.
Typical applications include digital power supplies, AC-DC and DC-DC converters, brushless motor drives, power factor correction stages, and advanced sensing and control nodes. The 28-pin SSOP footprint suits compact, cost-sensitive converter designs where GPIO count requirements are moderate.
Design considerations: supply decoupling close to VDD pins, careful analog grounding for the high-speed ADC, and MCLR-based ICSP programming via a 5-pin header are recommended. PWM dead-time and ADC trigger synchronization should be verified against the device family reference manual.

Typical Applications
DSPIC33CK64MP102T-I/SS is suitable for 6 applications: Digital Power Supplies, BLDC/PMSM Motor Control, Power Factor Correction (PFC), Industrial Sensing and Control Nodes, LED Drivers and Lighting Control, Embedded DSP and Signal Processing.
Digital Power Supplies
The DSPIC33CK64MP102T-I/SS fits digital power supply control because its 100 MIPS 16-bit core executes closed-loop compensation loops with deterministic latency, while the 12-bit high-speed ADC samples current and voltage feedback synchronized to the PWM carriers. On-chip op amps and comparators reduce external signal-conditioning BOM cost in buck, boost, LLC, and totem-pole PFC stages. The controller computes duty-cycle updates each switching cycle, supporting peak and average current-mode control. PWM modules provide fine edge resolution and programmable dead time for half-bridge and synchronous rectification topologies. Placed as the sole control element between the power stage and feedback dividers, it replaces analog control ICs while adding programmability, telemetry, and firmware-based protection such as cycle-by-cycle current limit and soft-start profiling.
Recommended
BLDC/PMSM Motor Control
Field-oriented control of brushless DC and permanent-magnet synchronous motors demands fast multiply-accumulate execution and precisely timed ADC sampling, both native strengths of the dsPIC33CK64MP102. The 100 MHz core executes Clarke/Park transforms and PI current loops within single PWM periods, while the high-speed ADC captures phase currents at the PWM center for noise-free sampling. On-chip comparators implement hardware overcurrent trip zones that shut PWM outputs faster than any software path. Integrated op amps amplify shunt currents without external amplifier ICs, reducing board area in the 28-SSOP footprint. Typical use is as the single control IC in 48V-class drives for power tools, e-bikes, HVAC blowers, and industrial servo stages, with sensorless or encoder-based commutation implemented in firmware.
Recommended
Power Factor Correction (PFC)
Average-current-mode PFC control benefits directly from the dsPIC33CK64MP102 combination of 100 MIPS throughput and synchronized ADC/PWM triggering. The controller samples rectified line voltage and inductor current every switching cycle, computes the current command from the voltage-loop output, and adjusts the boost-stage duty cycle with low control latency. Fast analog comparators provide hardware cycle-by-cycle current limiting for inrush and fault conditions. Firmware implements brownout detection, feedforward line compensation, and inrush soft-start profiles without additional analog circuitry. The 3.3V supply domain and remappable peripheral pins simplify integration into compact AC-DC front ends for server power supplies, telecom rectifiers, and LED drivers, where the 28-pin SSOP keeps controller cost and footprint low.
Recommended
Industrial Sensing and Control Nodes
As an industrial sensing and control node, the DSPIC33CK64MP102T-I/SS pairs its DSP capability - digital filtering, RMS computation, FFT-based analysis - with standard serial interfaces for reporting results over UART, SPI, or I2C. The 12-bit high-speed ADC digitizes sensor channels at rates sufficient for power-quality monitoring, current signature analysis, and vibration or acoustic diagnostics. On-chip comparators create threshold alarms that operate independently of the CPU. With 64 KB Flash, the part stores calibration tables and compensation coefficients alongside application firmware, and the -40C to +85C industrial grade suits factory-floor environments. The 28-SSOP package fits dense DIN-rail modules and distributed IO units where sensing intelligence is pushed to the edge of industrial automation networks.
Recommended
LED Drivers and Lighting Control
Digital LED drivers use the dsPIC33CK64MP102 to implement constant-current regulation, dimming curves, and multi-string balancing under firmware control. The 100 MHz core runs fast inner current loops for buck or boost LED stages while a slower outer loop manages color mixing, thermal derating, and communication protocols such as DALI or DMX over its UART/I2C peripherals. PWM and ADC synchronization enables accurate average-current sensing across wide dimming ranges, including deep-dim operation where pulse-skipping precision matters. On-chip op amps condition shunt feedback without external amplifiers. Housed in the compact 28-SSOP package, the controller serves as the complete digital engine for high-bay fixtures, stage lighting, and horticultural luminaires requiring both power conversion and network control in one IC.
Recommended
Embedded DSP and Signal Processing
For cost-sensitive DSP tasks, the dsPIC33CK64MP102 executes 16-bit fixed-point algorithms - FIR and IIR filtering, PID, correlation, and transform code - using single-cycle multiply-accumulate instructions at up to 100 MIPS. The zero-overhead DO loop structure and DSP addressing modes keep inner loops cycle-exact, which matters for real-time audio conditioning, sensor fusion, and communications preprocessing. With 64 KB Flash and 8 KB RAM, the part holds both algorithm and application code without external memory in most designs, and 3.3V operation interfaces directly with standard analog front ends. The 28-SSOP package makes it practical to embed DSP capability into existing MCU-based boards as a coprocessor or standalone intelligent sensor, replacing discrete DSP-plus-MCU two-chip solutions.

Design Notes
Place 100 nF ceramic decoupling capacitors directly at each VDD/VSS and AVDD/AVSS pin pair with short, wide traces to the ground plane. The high-speed 12-bit ADC and on-chip op amps are sensitive to supply ripple; isolate the analog ground region under AVDD/AVSS from the PWM power ground with a single-point connection to prevent switching noise from corrupting ADC conversions. Follow the dsPIC33CK family reference manual layout guidance for digital power designs.
Synchronize ADC sampling to the PWM center or zero of the carrier using the ADC trigger-from-PWM feature to sample inductor current away from switching edges - this dramatically reduces sampling noise in current-mode control. When routing PGD/PGC programming traces, add series resistors and keep them short so ICSP programming remains reliable with the board powered in-circuit.
Do not exceed the absolute maximum ratings on MCLR or use an unregulated programming voltage. Configure configuration bits (oscillator source, watchdog, PWM pin state at reset) before production - default clock settings run the core far below 100 MIPS if the PLL is not enabled. Verify pin remapping conflicts: PPS (peripheral pin select) assignments must not be duplicated, or peripherals will not route as expected.
Estimated: for a 28-SSOP in still air, power dissipation is dominated by I/O and core current. At approximately 60 mA core current at 3.3V (worst-case active at 100 MIPS per family datasheet), dissipation is roughly 0.2 W, which is comfortably within the SSOP thermal capability without a heatsink. For extended-temp -E variants in enclosed motor drives, verify junction temperature with the datasheet theta-JA figure for your PCB copper area.
Compliance Information
RoHS compliance and lead-free status per standard Microchip production for current dsPIC33CK devices as listed by distributors. Formal REACH, halogen-free, and conflict-minerals declarations should be requested from Microchip documentation.
