DSPIC33FJ16MC102T-I/SS 概要
A digital signal controller combines the computational throughput of a DSP with the peripheral integration and ease of use of a microcontroller. Within the power-management hierarchy, the DSC sits between a general-purpose MCU and a dedicated DSP, making the dsPIC33F family a common choice for closed-loop motor control, digital power conversion, and sensor signal processing.
Key features include a motor control PWM (MCPWM) module for driving three-phase inverters, the CTMU (Charge Time Measurement Unit) for touch sensing and time measurement, and Peripheral Pin Select (PPS) for flexible remapping of digital peripherals onto I/O pins. Core-independent peripherals such as POR, brown-out detect/reset, and a watchdog timer improve system robustness. Connectivity covers I2C, SPI, UART/USART, IrDA, and LINbus, allowing direct interfacing with gate drivers, sensors, and automotive sub-networks.
Architecturally, the dsPIC33F core uses an enhanced 16-bit pipeline with DSP instruction support (barrel shifter, multiply-accumulate), operating from a 3.0V to 3.6V supply with a nominal 3.3V. The -I temperature grade covers -40C to +85C for industrial environments; the /SS suffix denotes the 28-lead SSOP surface-mount package and Tape-and-Reel delivery for automated assembly.
Typical applications include brushless DC and permanent-magnet motor drives, switch-mode power supplies and digital lighting, and embedded control nodes in industrial automation requiring LIN or UART connectivity.
Design consideration: budget program memory carefully - with 16KB FLASH, use the free MPLAB X toolchain and avoid heavy middleware stacks; the smaller 12KB dsPIC33FJ12MC202 may suffice for simple loops, while the 32KB variants give headroom.

主な用途
DSPIC33FJ16MC102T-I/SS の用途: 6 件s: BLDC/PMSM Motor Drives, Switch-Mode Power Supplies and Digital Lighting, Industrial Automation Sensor Nodes, Automotive Sub-Network Modules, Capacitive Touch and Time-Measurement Systems, Embedded Signal Processing and Data Acquisition.
BLDC/PMSM Motor Drives
The DSPIC33FJ16MC102T-I/SS was designed specifically for digital motor control: its dedicated MCPWM module generates complementary PWM outputs with hardware dead-time insertion, and high-speed comparators provide fast overcurrent trip without CPU latency. At 16 MIPS with DSP multiply-accumulate instructions, it executes field-oriented control (FOC) or sensorless trapezoidal BLDC loops for low- to mid-power fans, pumps, and appliances. Typical topology places the DSC between a current-shunt sense network and a three-phase gate driver, closing current loops in the tens-of-microseconds range. The 16KB FLASH accommodates a full FOC routine plus LIN or UART communications, making it a cost-optimized single-chip drive controller.

Switch-Mode Power Supplies and Digital Lighting
In digital power conversion, the DSPIC33FJ16MC102T-I/SS implements voltage-mode or current-mode control loops for LLC, buck, and PFC stages. The 16-bit core at 16 MIPS provides the loop bandwidth needed for 100-500 kHz converters, while PPS lets the designer route PWM outputs and ADC-trigger sources flexibly to minimize PCB crossings. In LED drivers and HID ballast replacements, the CTMU and comparators support fast fault detection and dimming-signal measurement. The 3.0V-3.6V operation suits designs with a 3.3V logic rail derived from an auxiliary flyback winding, and the brown-out reset guarantees safe startup behavior under sagging input conditions.
おすすめ
Industrial Automation Sensor Nodes
As a compact industrial control node, the DSPIC33FJ16MC102T-I/SS combines UART/USART, I2C, SPI, IrDA, and LINbus connectivity with the CTMU for capacitive or resistive sensing, allowing one 28-pin device to gather sensor data, run local filtering algorithms, and report over industrial serial networks. The -40C to +85C industrial temperature grade covers uncontrolled factory-floor environments, and the watchdog timer plus brown-out detection maintain watchdog-supervised operation during power disturbances. PPS pin remapping lets a single PCB layout serve multiple product variants by changing only firmware routing, reducing SKU proliferation and qualification costs in distributed I/O and sensing applications.
おすすめ
Automotive Sub-Network Modules
LINbus support makes the DSPIC33FJ16MC102T-I/SS well suited to automotive body and actuator sub-networks - seat adjusters, mirror controls, HVAC dampers, and small pump drives - where LIN is the mandated low-cost bus. The 16 MIPS core runs the LIN 2.x protocol stack alongside a small motor-control loop, while PPS allows flexible placement of LIN transceiver UART pins. Although this standard part is not AEC-Q100 qualified, it serves off-road, agricultural, and Tier-2 industrial-vehicle modules where full automotive qualification is not required; for under-hood temperatures, move to the -40C to +125C E-grade variant in the same 28-SSOP footprint.
おすすめ
Capacitive Touch and Time-Measurement Systems
The integrated Charge Time Measurement Unit (CTMU) turns the DSPIC33FJ16MC102T-I/SS into a single-chip touch interface: it injects precise charge currents into touch pads and measures charge time, detecting finger capacitance changes without a dedicated touch controller. The same CTMU supports ultrasonic flow measurement and resistance/capacitance metrology by timing charge intervals. Running the acquisition and debounce firmware within 16KB FLASH, the device can also drive feedback (LED, buzzer, or UART report) from the same pins via PPS remapping. This suits appliance panels, small HMI keypads, and low-cost instruments where a separate touch IC would add BOM cost and board area.
おすすめ
Embedded Signal Processing and Data Acquisition
With its DSP engine - barrel shifter, hardware multiply-accumulate, and modulo addressing - the DSPIC33FJ16MC102T-I/SS performs real-time digital filtering (IIR/FIR), FFT-based analysis, and sensor linearization on-board. The 1KB RAM constrains block sizes, so designers typically stream samples through small FIR filters rather than large FFT frames; for heavier processing, the pin-compatible DSPIC33FJ32MC102 doubles program space for coefficient tables and stack. Typical uses include vibration monitoring nodes, current-signal conditioning for predictive maintenance, and precision analog front-end control where the high-speed comparators provide hardware limiting and the UART streams processed results to a host controller.

設計ノート
The DSPIC33FJ16MC102T-I/SS requires a tightly regulated 3.0V-3.6V supply; exceeding 3.6V stresses the core regulator. Decouple each VDD pin with 0.1uF ceramic capacitors placed within 2 mm of the pins, plus 4.7-10uF bulk near the device. On motor-drive boards, separate the analog supply of the ADC/comparator inputs from gate-driver switching noise with an RC filter or ferrite bead. Estimated: at 16 MIPS full activity, core current draw is in the tens-of-mA range per the family datasheet, so a 100 mA-rated 3.3V LDO generally suffices.
In motor-control layouts, keep the MCPWM output traces short to gate drivers and route current-sense feedback away from PWM switching nodes. Use the exposed routing freedom of Peripheral Pin Select (PPS) during layout: assign PWM, UART, and comparator I/O on firmware before finalizing copper so that noisy PWM lines never cross analog sense traces. Place the CTMU touch pads with guard traces to adjacent ground and keep fringing capacitance consistent for stable threshold calibration. A solid ground plane under the 28-SSOP is strongly recommended.
Three frequent mistakes: (1) treating the device as 5V-tolerant - VDD max is 3.6V, so 5V UART or sensor outputs need level shifting; (2) forgetting that PPS must be configured in firmware before UART/LIN or remapped peripherals function - unconfigured pins default away from digital peripherals; (3) underestimating FLASH - 16KB fills quickly with LIN stacks and FOC math, so check the compiler memory map early and step up to the pin-compatible DSPIC33FJ32MC102-I/SS rather than squeezing late-stage features.
