DSPIC33CK64MC102T-I/SS 概要
A Digital Signal Controller combines the computational architecture of a microcontroller with DSP-class math acceleration in a single silicon device. In the embedded systems hierarchy, the DSC sits between general-purpose MCUs and dedicated DSPs, making the dsPIC33CK family well suited to closed-loop control systems that need fast multiply-accumulate operations alongside flexible peripherals.
Key features include operation at DC to 100 MIPS from a 3.0 V to 3.6 V supply, 64 KBytes of program Flash with ECC and fault-injection test support, and 8 KBytes of SRAM with Memory Built-In Self-Test (MBIST). On-chip analog resources include three operational amplifiers, a 12-bit ADC, an analog comparator, and a 12-bit DAC, while the PWM subsystem provides high-resolution outputs for precision power conversion.
The modified Harvard architecture executes DSP instructions with single-cycle MAC, and hardware support for functional safety (FuSa) designs targets applications where systematic integrity matters. The part is offered in automotive and AEC-Q100-relevant listings per distributor data.
Typical applications include brushless DC and PMSM motor control, low-voltage fan and motor-drive reference designs, digital power supplies, and advanced sensing nodes.
For design, the 3.0 V to 3.6 V operating window means the DSC should be powered from a clean 3.3 V rail; the -40C to +150C variant allows reduced MIPS above 125C.

主な用途
DSPIC33CK64MC102T-I/SS の用途: 6 件s: BLDC/PMSM Motor Control, Low-Voltage Fan and Motor-Drive Systems, Digital Power Supplies (SMPS/PFC), Advanced Sensing and Control Nodes, Touch and HMI Interfaces, Automotive and Functional-Safety Oriented Control.
BLDC/PMSM Motor Control
The DSPIC33CK64MC102T-I/SS fits motor control because its 100 MHz core executes field-oriented control loops with single-cycle DSP MAC instructions, while the high-speed PWM provides 2 ns output resolution for precise sine-wave drive. The three on-chip op amps can condition shunt-resistor phase currents without external amplifiers, and the 12-bit ADC samples them synchronously with the PWM for minimal loop delay. Typical usage places the DSC in a three-phase inverter stage driving a gate-driver front end, with the comparator supporting fast over-current protection. Compared with a general MCU, the integrated analog front end reduces BOM count and improves current-loop bandwidth; the trade-off is the 3.0 V to 3.6 V supply window, which requires a clean 3.3 V rail from the inverter supply.
おすすめ
Low-Voltage Fan and Motor-Drive Systems
Microchip's low-voltage fan reference design (DS50003310A) demonstrates the dsPIC33CK64MC102T in a cost-optimized motor-drive BOM, where the DSC is powered from a 3.3 V MIC5205 LDO fed by a 10 V bus. The DSPIC33CK64MC102T-I/SS suits this role because sensorless trapezoidal or FOC control fits comfortably in its 64 KB ECC Flash, and the 2 ns PWM resolution enables quiet acoustic performance at low fan speeds. The integrated 12-bit ADC reads back EMF or shunt currents, while the comparator implements cycle-by-cycle current limiting in hardware with no CPU latency. Designers gain minimum-component-count cost targets; the main consideration is ensuring PWM dead-time settings match the chosen gate-driver propagation delays to prevent shoot-through in the bridge.
おすすめ
Digital Power Supplies (SMPS/PFC)
The DSPIC33CK64MC102T-I/SS serves digital power conversion because its high-resolution PWM (2 ns) supports precise duty-cycle and phase control in buck, boost, LLC, and PFC topologies, while the 100 MHz core closes voltage and current loops at switching frequencies well above 100 kHz. The 12-bit ADC can be triggered by the PWM for cycle-by-cycle sampling, and the analog comparator provides hardware over-current shutdown independent of firmware. The 3 op amps condition current-shunt signals on-chip, eliminating external amplifiers in space-constrained power boards. Designers should budget Flash carefully: 64 KB accommodates compensators, state machines, and PMBus-style communication for a single-converter system, but multi-loop multi-rail designs may need the larger dsPIC33CK MP family instead.
おすすめ
Advanced Sensing and Control Nodes
For advanced sensing, the DSPIC33CK64MC102T-I/SS combines DSP math capability with a self-contained analog suite: the 12-bit ADC, three op amps, and 12-bit DAC allow signal conditioning, acquisition, and excitation generation on one chip. A 100 MHz core runs FFT or filter algorithms on sampled data with single-cycle MAC throughput, enabling vibration, current, or acoustic sensing nodes that make local decisions. The 8 KB MBIST-enabled SRAM and ECC Flash support dependable operation, and four DMA channels stream ADC results without CPU intervention, keeping loop jitter low. Typical deployments place the node on an industrial 24 V bus with a 3.3 V local regulator. The constraint to note is the 21 I/O count and 8 KB RAM, which bound how many sensor channels and buffering depth a single chip can host.
おすすめ
Touch and HMI Interfaces
Microchip positions the dsPIC33CK64MC10X family for touch and advanced control applications, and the DSPIC33CK64MC102T-I/SS implements capacitive-touch buttons and sliders using charge-transfer measurement on its ADC channels with the 100 MHz core handling the signal processing. Because the DSC integrates three op amps, comparator, and 12-bit DAC alongside touch sensing, a single chip can serve HMI plus motor or power control, cutting BOM cost in appliances and white goods. Firmware such as Microchip touch libraries fits in the 64 KB ECC Flash, and the 21 I/O pins drive LEDs or communicate over the three serial interfaces. Design discipline is needed: touch electrode layout, ground guarding, and ADC sampling schedule must follow Microchip touch design guides for reliable response in noisy motor-drive environments.
おすすめ
Automotive and Functional-Safety Oriented Control
The DSPIC33CK64MC102T-I/SS is catalogued under automotive and AEC-Q100 listings and supports Functional Safety (FuSa) development, making it suitable for auxiliary motor, pump, and actuator control in vehicles. Hardware trust anchors matter here: program Flash ECC corrects single-bit errors, fault-injection testing validates error handling, and SRAM MBIST screens memory at startup, all documented in the Microchip datasheet. The -40C to +125C industrial grade covers most under-hood-adjacent modules; for harsher locations the -E grade variant extends to +150C at 70 MIPS. Designers typically pair the DSC with a qualified gate driver and LIN/CAN transceiver, using the 3 op amp front end for phase-current sensing. Note that safety certification depends on the complete system development flow, not the silicon alone.

設計ノート
The DSPIC33CK64MC102T-I/SS requires a regulated 3.0 V to 3.6 V supply; it cannot tolerate 5 V on VDD. In systems from higher buses, follow Microchip's low-voltage fan reference design (DS50003310A), which derives 3.3 V from a 10 V rail via a MIC5205 LDO. Decouple each VDD pin with 0.1 uF ceramics placed within 2 mm of the pin, plus bulk 4.7 uF to 10 uF. Keep analog (AVDD) fed through an RC or ferrite filter from the digital rail so ADC and op amp accuracy is not degraded by digital switching noise.
The 28-SSOP package has a 0.65 mm pin pitch; design the land pattern per the Microchip datasheet footprint and inspect paste apertures to avoid bridging in reflow. Place the PWM outputs to the gate driver with short, matched traces, and route ADC input traces away from PWM and clock lines. Use a solid ground plane and return analog currents through the analog region. The MCLR pin needs a 10 k pull-up plus programming-connector provision (PGD/PGC) for in-circuit debugging with PICkit or ICD tools.
Do not exceed 100 MIPS when ambient exceeds +125C - that limit applies only to the -40C to +125C range; the -E grade allows 70 MIPS up to +150C. Firmware portability is limited within the family: the DSPIC33CK32MC102 variant has only 32 KB Flash, so link-map and bootloader assumptions must be re-checked when swapping variants on the same board. Finally, verify peripheral pin-select (PPS) routing when moving designs between 28-pin family members, since available pin functions differ from larger MP packages.
