DSPIC33CK128MC102T-I/2N 개요
A Digital Signal Controller combines the computational throughput of a digital signal processor (DSP) with the peripheral integration and deterministic control of a microcontroller (MCU). Within the power-management hierarchy of embedded systems, the DSC sits between general-purpose MCUs and full DSPs, making the dsPIC33CK family a common choice in the microcontroller -> DSC -> DSP spectrum for real-time control loops.
Key features include the 100 MHz dsPIC33CK core with DSP engine and barrel shifter, 128 KB Flash and 16 KB RAM, on-chip operational amplifiers (OpAmps), a 12-bit ADC, and high-resolution PWM peripherals - the exact combination cited by Mouser: "dsPIC33C 100MHz, 128KB Flash, 16KB RAM, OpAmps, 12bit ADC, PWM". Four DMA channels enable efficient data movement without CPU intervention.
The dsPIC33CK architecture builds on Microchip's 16-bit dsPIC33 heritage, adding a faster core, improved ADC throughput, and current-sensing op-amps aimed at field-oriented control (FOC). The single-core design simplifies software compared to the dual-core dsPIC33CH family while retaining DSP multiply-accumulate performance for control mathematics.
Typical applications include high-speed motor control (BLDC/PMSM FOC), digital power conversion (totem-pole PFC, LLC), and audio/signal processing, as identified in distributor listings by Lisleapex and Microchip.
Design consideration: verify the pin mapping for the 28-UQFN (2N) package directly in the Microchip datasheet before layout, as pin functions are multiplexed across the small 28-pin count.

일반적인 애플리케이션
DSPIC33CK128MC102T-I/2N 적합 용도: 6 애플리케이션s: Brushless Motor Control (FOC), Digital Power Conversion, Audio and Signal Processing, Industrial Automation and Sensing, Consumer Appliances, Battery-Powered and Portable Equipment.
Brushless Motor Control (FOC)
The DSPIC33CK128MC102T-I/2N fits field-oriented control (FOC) of BLDC and PMSM motors because its 100 MHz core executes Clarke/Park transforms and PI current loops with DSP multiply-accumulate instructions at PWM frequencies well into the tens of kHz. The on-chip operational amplifiers amplify low-level shunt-resistor current signals before the 12-bit ADC samples them, and four DMA channels move ADC results without CPU intervention, keeping loop jitter minimal. The high-resolution PWM generates complementary outputs with dead-time insertion for three-phase inverters, and 128 KB Flash accommodates sensorless observers such as sliding-mode or flux estimators with headroom to spare.

Digital Power Conversion
For digital power supplies such as totem-pole PFC, LLC, and buck/boost stages, the DSPIC33CK128MC102T-I/2N provides the combination of a 100 MHz control core and high-resolution PWM needed for tight regulation at switching frequencies where conventional MCUs cannot close the loop fast enough. The 12-bit ADC with DMA-driven sampling captures input/output voltage and inductor current synchronously with the PWM period, while the DSP engine executes the compensator arithmetic deterministically. The integrated op-amps condition current-shunt feedback on-chip, reducing BOM count, and 128 KB Flash leaves room for multiple converter profiles plus communication firmware in a single device.
추천
Audio and Signal Processing
Distributor listings for the DSPIC33CK128MC102T-I/2N identify audio processing as a target use case. The 100 MHz DSP core performs FIR/IIR filtering, sample-rate conversion, and effects algorithms efficiently using hardware multiply-accumulate, while 16 KB RAM provides working buffers for frame-based audio at standard sample rates. The 12-bit ADC can digitize line-level inputs through the integrated op-amps, and the high-resolution PWM with DMA can serve as a basic output stage in cost-sensitive audio products. 128 KB Flash accommodates a complete signal-chain firmware including communication and housekeeping code.
추천
Industrial Automation and Sensing
In industrial nodes, the DSPIC33CK128MC102T-I/2N combines deterministic control with the -40C to +85C industrial temperature rating demanded by factory environments. Its DSP throughput supports vibration-analysis and condition-monitoring preprocessing at the edge, while the 12-bit ADC and integrated op-amps digitize 4-20 mA and sensor signals. Four DMA channels keep communication servicing off the control loop, and low-power modes suit battery-backed monitoring units. The 28-UQFN 6x6 mm package conserves PCB area in compact I/O modules, and 128 KB Flash provides space for protocol stacks and field-updatable application code.

Consumer Appliances
Appliance subsystems - fan motors, pumps, compressors, and heaters - benefit from the DSPIC33CK128MC102T-I/2N's single-chip integration of motor control and system supervision. The 100 MHz core closes sensorless FOC loops efficiently, the integrated op-amps and 12-bit ADC handle current and temperature feedback without external analog ICs, and the high-resolution PWM drives inverter stages with precise dead-time control for acoustic-noise reduction. RoHS-compliant, lead-free 28-UQFN packaging supports high-volume automated assembly, and 128 KB Flash lets one PCB platform serve multiple appliance SKUs through firmware variants.
추천
Battery-Powered and Portable Equipment
The DSPIC33CK128MC102T-I/2N suits portable, battery-operated control applications through its low-power modes that cut consumption between control events while the 100 MHz core still delivers bursts of DSP performance when the power stage needs it. The integrated op-amps and 12-bit ADC measure battery current and pack voltage for fuel gauging and protection, and the high-resolution PWM drives charging or motor stages from the same die. The small 28-UQFN 6x6x0.55 mm footprint keeps end-product PCBs compact, and 128 KB Flash supports sophisticated power-management state machines alongside the primary control firmware.

설계 노트
The 28-UQFN (6x6x0.55 mm) package has a 0.4-0.5 mm pitch land pattern with a central exposed thermal pad that should be soldered to a grounded copper pour for both heat dissipation and grounding of analog circuits. Use a standard QFN stencil with approximately 50% coverage on the center pad to avoid solder voids. Because the /2N package is lead-frame based with perimeter pins only, verify the exact pin functions against the dsPIC33CK128MC102 family datasheet pin diagram before routing - analog inputs, op-amp pins, and PWM outputs are multiplexed on this reduced pin count.
Decouple the VDD core and I/O supply rails with 0.1 uF ceramic capacitors placed within 2 mm of each supply pin, plus a 4.7-10 uF bulk capacitor per rail. The dsPIC33CK core at 100 MHz draws transient current on every clock edge; a shared, poorly decoupled rail between the core regulator output and analog op-amp supplies will degrade ADC accuracy. When using the on-chip op-amps for current sensing, route the shunt signal to the amplifier inputs as a Kelvin connection and keep the amplifier output trace short to the ADC input pin.
Two frequent mistakes with the dsPIC33CK family: (1) MCLR must be pulled up (typically 10 kohm) and kept below the absolute maximum rating; leaving it floating causes sporadic resets. (2) The 100 MHz core clock is derived from an internal PLL - configure the PLL divider ratios within the datasheet's allowed input frequency window, and confirm startup behavior before committing oscillator settings in firmware. Also note the /I grade is rated to +85C: for enclosed drives that exceed this ambient, substitute the pin-compatible /E grade (-40C to +125C) instead of derating the design.
