DSPIC33CK32MC102T-I/SS 概要
A Digital Signal Controller combines the computational architecture of a digital signal processor with the peripheral integration and ease of use of a microcontroller, occupying the middle tier of the embedded control hierarchy: microcontroller -> DSC -> application-specific DSP. DSCs are optimized for real-time closed-loop control, where fast interrupt latency, deterministic math, and tightly coupled PWM/ADC peripherals matter more than raw throughput.
Key features of the dsPIC33CK32MC102 include a single 100 MHz dsPIC DSC core with DSP engine, 3 integrated operational amplifiers (OpAmps) that offload external analog front-ends, 12-bit ADCs for high-resolution current and voltage sensing, and high-resolution PWM peripherals for motor control and digital power conversion. The Flash supports ECC and fault-injection testing, and the SRAM includes Memory Built-in Self-Test (MBIST), supporting functional-safety (FuSa) development. The device operates from 3.0 V to 3.6 V.
Technically, the modified Harvard architecture uses 24-bit instruction words with DSP multiply-accumulate instructions, barrel shifting, and 4 DMA channels that move ADC and UART data without CPU intervention. Three serial I/O ports (UART, SPI, I2C) and 3 timers round out the peripheral set.
Typical applications include brushless DC and PMSM motor control, digital power supplies (LLC, totem-pole PFC), touch sensing, and advanced sensor interfaces - all domains where the 100 MIPS core and integrated op-amps reduce BOM count and loop latency.
Design consideration: the 3.0-3.6 V supply window requires a tight LDO or buck regulator; also note the device must be decoupled with low-ESR ceramics on all VDD pins per Microchip layout guidelines.

主な用途
DSPIC33CK32MC102T-I/SS の用途: 6 件s: BLDC/PMSM Motor Control, Digital Power Conversion, Automotive Sensing and Control Nodes, Capacitive Touch Interfaces, Advanced Sensor Signal Chains, Industrial Embedded Control.
BLDC/PMSM Motor Control
The DSPIC33CK32MC102T-I/SS fits sensorless and sensored motor-control drives because its 100 MHz (100 MIPS) dsPIC33CK core executes field-oriented control (FOC) loops fast enough for high electrical-speed motors, while the 3 integrated op-amps amplify low-side shunt currents without an external amplifier IC. In a typical topology, the 12-bit ADC is triggered synchronously by the high-resolution PWM center to sample phase currents at PWM mid-point, minimizing switching noise; the 4 DMA channels move samples to SRAM without CPU overhead. Compared with a general MCU solution, the deterministic DSP multiply-accumulate engine and integrated analog reduce loop latency and BOM cost, making the MC variant ideal for cost-optimized industrial drives up to a few hundred watts.
おすすめ
Digital Power Conversion
The DSPIC33CK32MC102T-I/SS is well suited to LLC converters, totem-pole PFC stages, and DC-DC modules where the 100 MIPS core closes voltage and current loops at switching frequencies of 100 kHz to several hundred kHz. The high-resolution PWM peripherals provide sub-nanosecond effective duty-cycle resolution for precise phase management, and the 12-bit ADC with DMA captures fast current transients for cycle-by-cycle limiting. A key quantified benefit is loop speed: a proportional-integral current loop can execute well within one switching period at 100 MIPS, meeting transient-response targets that 8-bit or slower 16-bit MCUs miss. The 3.0-3.6 V supply and 28-SSOP footprint allow the controller to sit directly on the power board near the gate-driver circuitry.
おすすめ
Automotive Sensing and Control Nodes
Thanks to AEC-Q100 qualification and functional-safety features (ECC on program Flash and SRAM Memory Built-in Self-Test), the DSPIC33CK32MC102T-I/SS serves automotive body, pump, fan, and sensor-node controllers. The -40C to +85C I-grade rating covers cabin and under-chassis zones, while the /E variant extends to +125C for under-hood use in the same 28-SSOP footprint. The 3 op-amps condition resistive or inductive sensors locally, and the UART/SPI/I2C ports integrate with CAN-transceiver-equipped or LIN-adjacent architectures through external transceivers. Using ECC and MBIST reduces the diagnostic burden on system-level safety analysis, shortening ISO 26262-style development time for ASIL-supported functions where a DSC-based node is acceptable.
おすすめ
Capacitive Touch Interfaces
Microchip explicitly lists touch sensing as a target for the dsPIC33CK family, and the DSPIC33CK32MC102T-I/SS implements charge-transfer touch scanning using the ADC and I/O with Microchip's Touch Controller library. The 100 MHz core performs oversampling and drift-compensation algorithms in the background while the 12-bit ADC measures channel charge times with microsecond-level determinism, supporting buttons, sliders, and wheels on a single 28-pin device. Because touch scanning shares the ADC with other sensing tasks, the 4 DMA channels keep raw samples off the CPU, preserving headroom for the main application. Typical products include appliance panels, light switches, and industrial HMI sub-panels where the integrated op-amps remain available for sensor front-ends.
おすすめ
Advanced Sensor Signal Chains
The DSPIC33CK32MC102T-I/SS consolidates an entire analog sensor front-end on chip: the 3 operational amplifiers can be configured as gain stages or filters for bridge, thermocouple, or current-shunt signals, feeding the 12-bit ADC directly. This eliminates discrete op-amp ICs, shrinking the PCB area of industrial sensor nodes and portable instrumentation. The 100 MIPS DSP engine applies offset correction, averaging, and FFT-based analysis in real time, while the I2C/SPI/UART ports stream processed data to a host. A concrete benefit is signal-chain noise: shortening the analog path from external amplifier to ADC by placing both on the same die reduces pickup at the sensitive high-impedance node. End products include condition-monitoring nodes, smart transmitters, and weigh-scale front ends.
おすすめ
Industrial Embedded Control
As a general industrial controller, the DSPIC33CK32MC102T-I/SS handles valve drivers, actuator control, lighting ballasts, and small PLC I/O modules. The -40C to +85C industrial temperature grade and 3.0-3.6 V operation align with standard industrial 3.3 V rails, and the 32 KB ECC-protected Flash provides firmware integrity without external memory. The 3 timers plus 4 DMA channels manage multi-task timing deterministically, while UART, SPI, and I2C support Modbus-RTU, sensor buses, and configuration links. Its 28-SSOP package fits dense DIN-rail and embedded boards where a 64- or 100-pin controller is oversized. Code developed on larger dsPIC33CK MP devices ports directly to this 32 KB part when the application footprint shrinks, protecting software investment.

設計ノート
The dsPIC33CK32MC102 requires a tight 3.0-3.6 V supply. Feed all VDD pins from a low-ESR 3.3 V LDO or buck regulator and place 100 nF ceramic decoupling capacitors within 2 mm of each VDD/VSS pair, plus one 4.7-10 uF bulk capacitor near the device. Because core and I/O share the rail on this family, supply ripple directly modulates ADC accuracy - budget at least 60 dB PSRR in the regulator or add an RC/LC filter for the analog rail (AVSS pin at pin 28 must tie to a clean ground return). Estimated: a 30 mA average core current from a 3.3 V rail dissipates about 0.1 W, well within SSOP thermal limits without a heatsink.
For motor-control or digital-power layouts, keep the shunt-resistor-to-op-amp-input traces short and symmetric, and route them as Kelvin connections to pins 6 and 18 (C1IN1-/C1IN1+). Separate the analog ground region connected to AVSS from power-switching ground, joining them at a single star point near the shunt return. Place the 28-SSOP so PWM outputs (pins 11-12) face the gate-driver stage to minimize loop area. Follow Microchip's dsPIC33CK family layout guidelines in the datasheet PCB chapter; violating analog-ground separation is the most common cause of noisy ADC readings in first-pass boards.
Three frequent mistakes with this part: (1) selecting the I-grade (-40C to +85C) for designs that later migrate to under-hood locations - the /E variant in the same 28-SSOP footprint solves this without a respin; (2) underestimating 32 KB Flash - ECC adds safe operation but not capacity, so use the pin-compatible 64 KB dsPIC33CK64MC102 when firmware margins are tight; (3) ignoring the peripheral Pin Select (PPS) mapping - UART/SPI pins are remappable, so verify the pinout table in the family datasheet before finalizing routing, and always reserve PGD1/PGC1 (pins 21-22) access for in-circuit debug programming.
