DSPIC33CK64MC102-I/SS 概要
A Digital Signal Controller combines the computational strengths of a microcontroller with DSP math capabilities such as single-cycle MAC and divide instructions. Within the power-management hierarchy of embedded processors, the dsPIC33CK family sits between general-purpose 16-bit MCUs and full DSPs, making it a popular choice for closed-loop control systems that need deterministic, fast interrupt response.
Key features include operation from 3.0 V to 3.6 V across -40C to +125C (DC to 100 MIPS), program Flash with ECC and fault-injection testing, and SRAM with Memory Built-In Self-Test (MBIST). Integrated analog includes 12-bit ADCs, operational amplifiers (Op Amps), and comparators, alongside high-resolution PWM peripherals for power conversion.
The dsPIC33CK core is a modified Harvard architecture with a single 100 MHz core, enhanced on-chip peripherals, and multiple PGEC/PGED pairs for in-circuit serial programming (ICSP). Deterministic 100 MIPS performance supports fast control loops such as Field-Oriented Control (FOC) without software jitter.
Typical applications include brushless DC and PMSM motor control, digital power supplies and PFC stages, advanced sensing, and capacitive touch interfaces. The integrated Op Amps and 12-bit ADC reduce external component count in current-sense front ends.
Design consideration: keep all VDD/VSS pairs connected per the datasheet and decouple AVDD separately from the digital rail for best ADC accuracy; use any PGEC/PGED pair as a matched pair during debugging.

主な用途
DSPIC33CK64MC102-I/SS の用途: 6 件s: BLDC/PMSM Motor Control (FOC), Digital Power Supplies and PFC, Advanced Sensing and Precision Measurement, Capacitive Touch Interfaces, Embedded Industrial Control and Automation Nodes, Consumer Appliance Power and Motor Boards.
BLDC/PMSM Motor Control (FOC)
The DSPIC33CK64MC102 fits brushless DC and PMSM Field-Oriented Control because its 100 MHz dsPIC33CK core executes the FOC current loop deterministically at up to 100 MIPS, and its high-resolution PWM generates precise duty updates for three-phase inverters. The on-chip Op Amps amplify shunt current signals before the 12-bit ADC samples them, eliminating external amplifier ICs and reducing phase-current measurement error and BOM cost. In a typical topology, phase shunt voltages feed the Op Amps, the ADC triggers from the PWM period boundary, and the FOC loop closes within a single PWM cycle. The trade-off versus larger MP-series parts is memory: 64 KB Flash suits single-motor FOC, but field-weakening tables plus logging may require a 128-256 KB sibling. ECC Flash and MBIST further support safety-relevant drive designs.
おすすめ
Digital Power Supplies and PFC
Digital LLC, buck-boost, and PFC stages benefit directly from the DSPIC33CK64MC102: the high-resolution PWM provides fine duty and phase resolution for soft-switching control, while the 12-bit ADC with PWM-triggered sampling captures output voltage and current at the optimal instant in the switching cycle. The integrated comparators support fast overcurrent protection with cycle-by-cycle current limiting independent of CPU latency, a critical safety behavior in power conversion. Running at 100 MIPS, the core closes voltage/current loops at switching frequencies well beyond 100 kHz without jitter. Design consideration: use the ferrite-filtered AVDD rail for ADC accuracy and verify comparator threshold settings against the shunt sense range. For higher-power multi-loop systems, pin-compatible 256 KB MP-series variants add headroom without PCB redesign.
おすすめ
Advanced Sensing and Precision Measurement
Sensor front ends use the DSPIC33CK64MC102 where deterministic sampling and on-chip analog reduce system noise and cost. The 12-bit ADC with multiple channels, integrated Op Amps for signal conditioning, and 4 DMA channels allow continuous data streaming to SRAM without CPU intervention, preserving 100 MIPS headroom for DSP filtering such as fixed-point FFT and digital notch filters via the core MAC instructions. ECC Flash and MBIST improve measurement-system integrity in industrial monitoring nodes. In a typical flow, the ADC DMA stream is filtered in software and results are reported over one of the three serial interfaces. The -40C to +125C industrial range and 3.0-3.6 V supply suit factory-floor environments; for extended -40C to +150C sensing, derate operation to 70 MIPS per the datasheet.
おすすめ
Capacitive Touch Interfaces
Microchip positions the dsPIC33CK64MC10X family for touch applications, and the DSPIC33CK64MC102 implements capacitive touch sensing using charge-time measurement on its ADC and comparator resources without a dedicated touch controller. The 100 MHz core runs the Microchip touch library with enough margin to scan multiple keys plus drive UI feedback and communications simultaneously. Because the ADC, Op Amps, and comparators are time-multiplexed with touch acquisition, the deterministic interrupt structure of the dsPIC33CK core keeps scan timing consistent, which is essential for stable baseline drift compensation in appliances, cooktops, and industrial panels. Design note: allocate touch-sense pins away from high dV/dt PWM nets on the 28-pin SSOP, as the limited pin count of the 102 variant constrains simultaneous touch keys and motor-control outputs.
おすすめ
Embedded Industrial Control and Automation Nodes
As a general industrial controller, the DSPIC33CK64MC102 combines 16-bit control-loop performance with three serial I/O interfaces for RS-485/Modbus-style field connectivity, three timers for sequencing, and 4 DMA channels for background data movement. The 64 KB ECC Flash accommodates protocol stacks plus application logic, and MBIST plus ECC support the integrity requirements of factory automation equipment. Operating at 100 MIPS from a single 3.3 V rail across -40C to +125C simplifies power design in crowded control cabinets, while the 28-SSOP with 0.65 mm pitch is hand-solderable for service and rework. A common architecture pairs this DSC with an isolated RS-485 transceiver and a small buck converter. If future firmware growth is expected, the pin-compatible DSPIC33CK256MP202-I/SS offers a no-redesign upgrade path.
おすすめ
Consumer Appliance Power and Motor Boards
Appliance boards - fans, pumps, compressors, blenders - use the DSPIC33CK64MC102 where a single low-cost DSC replaces separate MCU, touch controller, and analog front-end ICs. The on-chip Op Amps and 12-bit ADC handle motor current sensing, comparators provide hardware overcurrent trip, and touch sensing runs on the same silicon, cutting BOM count on cost-sensitive designs. Microchip's Value Line positioning of the dsPIC33CK family targets exactly this segment with 100 MIPS deterministic performance at entry-level pricing. Firmware for sensorless BEMF or shunt-based FOC fits comfortably in 64 KB Flash. Production consideration: the -I suffix certifies -40C to +125C operation for the hot interior of appliances, and the 28-SSOP tape-and-reel format supports high-volume SMT lines; -E suffix variants extend to 150C environments at 70 MIPS.

設計ノート
Supply the DSPIC33CK64MC102 from a clean 3.3 V rail (3.0-3.6 V per datasheet). Decouple each VDD pin with 100 nF ceramic capacitors placed within 2 mm of the pin, plus one 4.7-10 uF bulk capacitor. Power AVDD through an RC or ferrite filter from the digital rail; ADC reference quality directly sets 12-bit conversion accuracy. Estimated: at 100 MIPS typical core current of roughly 40-50 mA (verify exact value in the datasheet electrical characteristics section), a 3.3 V/100 mA LDO provides adequate margin with PWM-driven GPIO loads.
ICSP pairing errors are the most common bring-up failure: the DSPIC33CK64MC102 has multiple PGECx/PGEDx pairs, and the debugger clock and data must come from the SAME pair (e.g., PGEC2 with PGED2). Additionally, connect ALL VDD and VSS pins - leaving one floating causes erratic resets. Reserved pins (e.g., VCAP) must have the specified capacitor to ground; do not repurpose them as GPIO. Always verify the configuration-bit settings for oscillator startup, as the default FRC may differ from your intended crystal/PLL configuration.
On a 28-SSOP (0.65 mm pitch) footprint, route PWM outputs away from analog sense traces feeding the Op Amp/ADC channels to prevent switching noise coupling into the 12-bit ADC. Use a solid ground plane and keep the analog ground return for AVSS separate from high-current motor or power-conversion grounds, tying them at a single star point. For motor-control boards, add small series resistors (22-33 ohm) on gate-driver outputs driven by the high-resolution PWM to damp ringing at the package pins.
The SSOP-28 plastic package dissipates little heat at typical operating currents, but extended-temperature designs should be checked: Estimated - at 50 mA core current plus 20 mA of I/O current on 3.3 V, dissipation is roughly 0.23 W; with SSOP-28 theta_JA typically around 100 C/W on a minimal 2-layer board, junction rise is about 23 C above ambient, keeping a +125C ambient design near the limit. Use 2-oz copper and thermal vias near the package for -40C to +150C applications, and derate to 70 MIPS per the datasheet in that range.
