DSPIC33CK128MC106T-I/PT 概要
A Digital Signal Controller combines the compute architecture of a microcontroller with the mathematical throughput of a digital signal processor. In the embedded hierarchy, the dsPIC33CK family sits between general-purpose MCUs and dedicated DSPs: it executes a single-cycle MAC-style DSP instruction set while retaining MCU-class peripherals, interrupts, and C-code development workflows, making it a natural fit for power conversion and real-time control loops.
Key features of the DSPIC33CK128MC106T-I/PT include the 100 MHz single dsPIC DSC core, high-speed PWM peripherals for switching power stages, on-chip 12-bit ADCs for multi-channel current and voltage sensing, and integrated operational amplifiers that reduce external component count in motor-control and digital-power designs. According to the Mouser listing, the part is summarized as a 16-bit DSC with 128KB Flash, 16KB RAM, OpAmps, 12-bit ADC, and PWM peripherals.
Technical depth comes from the dsPIC33C core architecture, which pairs the 16-bit CPU with zero-overhead DSP instructions and deterministic interrupt response, enabling closed-loop control frequencies well into the hundreds of kilohertz. The device family also supports CAN Flexible Data-Rate (CAN FD) communication, as described in the Microchip family datasheet for the dsPIC33CK128MC106 series, which totals 984 pages and covers 16-bit Digital Signal Controllers with High-Speed PWM and CAN FD.
Typical applications include brushless DC and PMSM motor control, digital power supplies (LLC, totem-pole PFC), solar micro-inverters, and industrial automation nodes that need CAN FD connectivity. The integrated op-amps and high-speed PWM make it especially attractive where a single chip must sense, compute, and drive a power stage.
A key design consideration is thermal and supply design: the 10x10 mm TQFP must dissipate heat through its copper land pattern, and the ADC/PWM clocking scheme should be planned early, since the 100 MHz core requires careful decoupling and a stable clock source.

主な用途
DSPIC33CK128MC106T-I/PT の用途: 6 件s: BLDC / PMSM Motor Control, Digital Power Supplies (LLC, Totem-Pole PFC), Solar Micro-Inverters, CAN FD Industrial Automation Nodes, Power Factor Correction (PFC) Stages, Embedded Control in Industrial Equipment.
BLDC / PMSM Motor Control
The DSPIC33CK128MC106T-I/PT fits sensorless and sensored field-oriented control (FOC) of brushless DC and permanent-magnet synchronous motors because its 100 MHz dsPIC33C core executes the Clarke/Park transforms and PI current loops with deterministic latency, while the high-speed PWM module generates complementary outputs with dead-time insertion. The on-chip 12-bit ADCs sample phase currents and the DC bus synchronously with the PWM carrier, and integrated op-amps amplify shunt-resistor signals without external amplifiers, reducing BOM cost. Placed as the single controller driving a three-phase inverter, it supports switching frequencies well above 20 kHz for audible-noise-free operation; the main design consideration is layout of the current-sense path to the ADC inputs to preserve accuracy.

Digital Power Supplies (LLC, Totem-Pole PFC)
The DSPIC33CK128MC106T-I/PT suits digitally controlled power conversion such as LLC resonant converters and totem-pole PFC stages. Its 100 MHz core closes voltage and current loops at high bandwidth, the high-speed PWM module supports frequency and phase-shift modulation with fine duty resolution, and the 12-bit ADCs provide the fast feedback sampling that digital power demands. Integrated op-amps condition current-shunt and voltage-divider signals on-chip, removing external error amplifiers. In a typical design the DSC replaces a dedicated analog PWM controller, adding programmability, telemetry, and adaptive startup. The key performance consideration is ADC-to-PWM trigger synchronization to minimize control-loop delay, and software-based protection (over-current, over-voltage) must be validated against worst-case transient response.
おすすめ
Solar Micro-Inverters
The DSPIC33CK128MC106T-I/PT is well matched to solar micro-inverter control, where a single low-cost DSC must run maximum-power-point-tracking (MPPT), grid-synchronization, and protection firmware concurrently. The 100 MHz 16-bit DSP core handles the arithmetic load of MPPT sampling and sinusoidal reference generation, while the high-speed PWM drives both the DC-DC boost stage and the DC-AC H-bridge with interlocked sequencing. On-chip 12-bit ADCs sample panel voltage/current and grid voltage with PWM-synchronized triggers, and the integrated op-amps reduce signal-conditioning component count in the compact, sealed micro-inverter enclosure. The -40C to +85C industrial rating of the -I grade supports outdoor installation environments without conformal-cooling measures.
おすすめ
CAN FD Industrial Automation Nodes
The DSPIC33CK128MC106T-I/PT serves as an intelligent CAN FD node in industrial automation systems. The dsPIC33CK128MC106 family datasheet describes these 16-bit DSCs as integrating CAN Flexible Data-Rate (CAN FD), enabling payloads up to 64 bytes at higher bit rates than classical CAN. Combined with the 100 MHz core and 16 KB RAM, the device can run local closed-loop control (for actuators, pumps, or sensor fusion) while streaming diagnostics and receiving setpoints over the CAN FD bus. The 128 KB Flash accommodates protocol stacks alongside control firmware, and the 64-pin TQFP provides enough I/O for local digital and analog functions. Design consideration: plan the peripheral pin selection (PPS) early so CAN FD and PWM functions do not conflict on desired pins.

Power Factor Correction (PFC) Stages
The DSPIC33CK128MC106T-I/PT is a strong fit for boost and totem-pole PFC controllers in server and telecom power supplies. The 100 MHz dsPIC33C core executes the average-current-mode control loop with sufficient bandwidth, and the high-speed PWM generates the switching waveform with programmable dead time and cycle-by-cycle current limiting. On-chip 12-bit ADCs sample inductor current and input/output voltages synchronized to the PWM period, giving predictable sampling delay for loop stability, while integrated op-amps condition the current-shunt signal directly. Digital implementation enables adaptive gain scheduling across the AC line cycle and compliance-friendly telemetry over CAN FD or other communication links. The main pitfall is software protection latency; hardware comparator-based limits should complement firmware supervision.
おすすめ
Embedded Control in Industrial Equipment
The DSPIC33CK128MC106T-I/PT works as the main embedded controller in industrial equipment such as welding machines, HVAC compressors, and robotics actuators, where motor or power control plus industrial communication are both required. The 100 MHz core with DSP instructions handles control algorithms and signal processing, the 128 KB Flash holds application firmware with room for field-updatable code, and CAN FD integration connects the equipment to factory networks. The 12-bit ADCs and op-amps support on-board sensing of temperatures, currents, and positions without additional analog ICs. The -40C to +85C industrial rating matches factory floor conditions. For equipment exposed to sustained temperatures above 85C, the -E/PT extended-temperature drop-in variant should be specified instead during design-in.

設計ノート
The 64-TQFP (10x10 mm) package requires a well-defined land pattern with thermal relief via the center of the footprint is not applicable (no exposed pad), so heat exits primarily through the leads. Provide solid ground planes on layer 2 connected at multiple pins, and keep the power PWM outputs away from the analog ADC inputs and op-amp pins to protect the 12-bit converter accuracy from switching transients. Follow the layout guidance in the dsPIC33CK family datasheet for decoupling each supply pin with 100 nF ceramics placed within a few millimeters.
Do not assume the ordering-code suffixes are interchangeable in purchasing systems: the 'T' suffix controls Tape & Reel delivery only, while '-I' and '-E' designate industrial versus extended temperature grade. Ordering DSPIC33CK128MC106-I/PT instead of the T version for a reel-based SMT line will break feeder setups. Also verify Peripheral Pin Select (PPS) mappings before finalizing schematic net assignments, because CAN FD, PWM, and communication functions compete for the same physical pins on the 64-pin device.
Estimated: plan the supply decoupling and power budget around the 100 MHz core clock. While exact core current is [DATA_NEEDED: core current at 100 MHz], dsPIC33C-class parts typically draw tens of milliamps at full speed; budget regulator headroom accordingly and verify against the family datasheet electrical specifications table. Sequence the analog supply for the ADC/op-amps cleanly with an RC or dedicated LDO if ultimate 12-bit accuracy is needed in electrically noisy motor-drive environments.
When driving an inverter bridge from the high-speed PWM outputs, add appropriate gate-driver buffering between the DSC pins and power MOSFET/IGBT gates - the TQFP pins are logic-level outputs and must never drive power-stage gates directly. Route PWM pairs as matched-length traces to the gate driver inputs to preserve dead-time symmetry, and place current-shunt sensing close to the DSC op-amp inputs with short, guarded traces to prevent offset errors at 12-bit resolution.
