DSPIC33FJ16MC102-E/SP 概要
A digital signal controller combines the computational architecture of a digital signal processor (DSP) with the peripheral set and ease of use of a microcontroller. Within the power-management hierarchy, the DSC sits above a general-purpose MCU and below a dedicated DSP: it executes DSP-class multiply-accumulate instructions while integrating motor-control peripherals such as high-speed PWM modules, making it the natural controller for brushless DC, permanent-magnet synchronous, and stepper motor systems.
Key features of this MC (Motor Control) family member include the Motor Control PWM (MCPWM) peripheral with complementary outputs and dead-time control, a 10-bit high-speed ADC capable of simultaneous sampling for current-loop closure, up to four high-speed analog comparators with direct PWM fault connections, and the Charge Time Measurement Unit (CTMU) for capacitive touch and time-domain measurements. Peripheral Pin Select (PPS) allows flexible digital peripheral remapping across I/O pins, easing PCB routing on the 28-pin footprint. The core runs at 40 MHz clock speed from a 3.0 V to 3.6 V supply.
Architecturally, the dsPIC33FJ core pairs a 16-bit modified Harvard pipeline with DSP engine features including a 17-bit by 17-bit multiplier, 40-bit accumulator, and dual operand fetch, enabling single-cycle MAC operations essential for field-oriented control (FOC) and other math-intensive motor algorithms. Flash program memory is self-programmable for field upgrades, and In-Circuit Serial Programming (ICSP) via PGECx/PGEDx pin pairs supports development with standard Microchip tools.
Typical applications include BLDC and PMSM motor drives, industrial automation sensors and actuators, automotive auxiliary motor control (the -E temperature variant is AEC-Q100 qualified per distributor data), and power conversion topologies requiring synchronized PWM and ADC sampling.
Design consideration: the 3.0 V to 3.6 V supply range requires a dedicated 3.3 V regulator; ensure all VDD/VSS pairs are decoupled with 0.1 uF ceramics placed close to the pins, and always drive the MCLR pin through a 10 kOhm pull-up for reliable ICSP debugging.

主な用途
DSPIC33FJ16MC102-E/SP の用途: 6 件s: BLDC Motor Control, Automotive Auxiliary Motor Drives, Industrial Automation and Pumps, Power Conversion and PFC, Capacitive Touch Interfaces, Embedded Sensing and Data Acquisition.
BLDC Motor Control
The DSPIC33FJ16MC102-E/SP fits BLDC motor drives because its MCPWM module provides complementary PWM outputs with programmable dead-time, directly driving a three-phase inverter gate-driver stage. The 10-bit high-speed ADC synchronizes current sampling with PWM centers, closing the current loop within one PWM period at 16 MIPS execution speed. Up to four high-speed comparators connect directly to PWM fault inputs for hardware overcurrent protection without CPU latency. Typical usage places the DSC between a shunt or Hall sensing front end and MOSFET gate drivers, implementing six-step or sensorless back-EMF commutation in firmware; the DSP engine's single-cycle MAC accelerates the observer mathematics. The trade-off versus a larger dsPIC is 16 KB Flash, sufficient for six-step schemes but tight for full sensorless FOC with complex compensation tables.
おすすめ
Automotive Auxiliary Motor Drives
Because the -E variant of the dsPIC33FJ16MC102 is AEC-Q100 qualified and rated -40C to +125C according to Microchip USA, it suits automotive auxiliary drives such as coolant pumps, HVAC blowers, throttle actuators, and window lifters. The 28-pin SPDIP through-hole package simplifies prototyping and low-volume service-friendly automotive subassemblies, while the 3.0 V to 3.6 V supply interfaces cleanly with 5 V automotive logic through the device's 5V-tolerant input pins. The MCPWM dead-time control protects the inverter during commutation of brushed or brushless loads, and the CTMU supports capacitive user interfaces such as touch controls on dashboard panels. Design consideration: automotive transients demand robust TVS protection and a qualified 3.3 V regulator on the supply rail.
おすすめ
Industrial Automation and Pumps
In factory automation, the DSPIC33FJ16MC102-E/SP drives conveyor motors, dosing pumps, and small spindle drives where its 16 MIPS DSP core executes PI current loops and speed ramps in firmware. Peripheral Pin Select (PPS) lets engineers route UART, SPI, or PWM functions to whichever of the available I/O pins best fits an existing backplane connector, reducing PCB rework on legacy through-hole platforms. The high-speed comparators implement cycle-by-cycle current limiting that operates even if firmware stalls - a critical safety behavior for unattended industrial equipment. The -40C to +125C operating range covers panel-mounted enclosures near heat sources. The 1 KB RAM constrains very long filter histories; industrial designs needing extensive buffering should step up to 32 KB Flash family members with 2 KB SRAM.
おすすめ
Power Conversion and PFC
The dsPIC33FJ16MC102 handles switch-mode power conversion such as boost power-factor-correction, LLC half-bridge control, and DC-DC conversion where its MCPWM center-aligned outputs and synchronized 10-bit ADC sample inductor current at the optimal instant. High-speed comparators feed cycle-by-cycle overcurrent limiting directly into the PWM hardware, providing microsecond-scale fault response that firmware alone cannot match. The DSP engine computes the PFC inner/outer loop mathematics with single-cycle MAC operations, maintaining stable control at loop bandwidths of several kilohertz. Designs needing sub-nanosecond PWM resolution for LLC resonant converters should instead consider the GS-family DSPIC33FJ16GS502, which offers a high-resolution PWM; the MC102 remains ideal for hard-switched topologies under 200 kHz.
おすすめ
Capacitive Touch Interfaces
The integrated Charge Time Measurement Unit (CTMU) makes the DSPIC33FJ16MC102-E/SP a capable host for capacitive touch buttons and sliders embedded in appliance panels, industrial keypads, and automotive trim. The CTMU measures charge time on sensing pads with consistent current injection, and the 16 MIPS core runs debounce and drift-compensation algorithms with headroom to spare while also managing motor or heater control in the same device - consolidating BOM cost in single-chip panel designs. Peripheral Pin Select allows touch channels and MCPWM outputs to coexist on the optimal pin assignments of the 28-pin package. Through-hole SPDIP mounting suits serviceable appliance boards where reflow constraints or field repairability favor DIP footprints over fine-pitch QFN/SSOP alternatives.
おすすめ
Embedded Sensing and Data Acquisition
With its 10-bit high-speed ADC, CTMU, and up to four analog comparators, the DSPIC33FJ16MC102-E/SP serves standalone acquisition nodes measuring sensor voltages, resistive elements, and time-domain signals. The CTMU enables precise resistance and capacitance measurement for level sensing, moisture detection, and ultrasonic transducer drive timing. The 16-bit DSP core applies IIR/FIR filtering and RMS computation in firmware at 16 MIPS, then streams results over UART or SPI configured anywhere on the pin map via PPS. The 5V-tolerant I/O pins simplify direct connection to legacy 5 V sensor outputs through simple dividers. For 12-bit resolution requirements, external delta-sigma ADCs pair over SPI; the on-chip 10-bit converter suffices for most monitoring and threshold-detection duties.

設計ノート
Supply the DSPIC33FJ16MC102-E/SP from a dedicated 3.3 V regulator within the 3.0 V to 3.6 V range. Decouple each VDD pin (pins 7 and 14) and the AVDD pin (pin 28) with 0.1 uF ceramic capacitors placed within 5 mm of the pins, plus one bulk 4.7 uF to 10 uF capacitor near the device. AVDD must be tied to VDD through its own decoupling - floating or sharing analog supply improperly is a common source of ADC noise. Estimated: at 16 MIPS full activity the core draws roughly 25 to 40 mA (per family electrical characteristics), so a 100 mA LDO provides comfortable margin.
ICSP programming requires PGECx/PGEDx pins to be used strictly as matched pairs: if PGEC2 carries ICSPCLK, ICSPDAT must connect to PGED2. Mixing pairs from different pairs will fail programming. Connect all VDD and VSS pins during programming and debugging. Keep MCLR pulled up with 10 kOhm and avoid large capacitors on MCLR - they slow reset and can block entry into programming mode. Reserved programming pins (PGEC1/PGED1 on pins 16/17) should not be loaded heavily in the final design.
For motor-control PWM outputs, route gate-drive signals away from the analog inputs (AN0-AN9) and keep the comparator current-sense traces short and paired with their ground returns. Synchronize ADC sampling to the MCPWM period using the ADC trigger feature rather than free-running sampling to avoid switching-noise corruption of current measurements. On through-hole SPDIP boards, add a local ground plane and place a small RC snubber on PWM edges if radiated emissions from long motor leads exceed limits.
