DSPIC33FJ128MC710A-E/PF 概要
What is a Digital Signal Controller (DSC)? A DSC is a hybrid microcontroller that combines an MCU's deterministic interrupt-driven control peripherals with a DSP's single-cycle MAC instruction set and dedicated compute engine. In the broader taxonomy, a DSC sits above a microcontroller (MCU) but below a standalone DSP, occupying the real-time control niche where MCU alone lacks MAC throughput and DSP alone lacks deterministic I/O. The dsPIC33F family targets applications requiring both closed-loop control and on-the-fly signal processing, putting it in the same role as Infineon Aurix TC2 or TI C2000 families.
The device integrates up to 85 general-purpose I/O, two CAN modules, two UART/SPI/I2C modules each, a 12-bit 1.1 Msps ADC with up to 24 channels, six PWM outputs with flexible fault input, and a 16-bit timer/capture block. The DSP engine adds fractional and integer MAC, barrel shifter, and saturating arithmetic for tight inner-loop execution. 3.0 V to 3.6 V single-supply operation and an extended -40 C to +125 C junction range suit industrial motor drives.
Architecturally, the dsPIC33FJ128MC710A pairs a Harvard bus with a 40 MHz oscillator and PLL providing up to 80 MHz internal FCY (40 MIPS). This is more than double typical 16-bit MCU throughput and enables sensorless motor control loops to execute within 10 us. The integration of CAN and dedicated motor-control PWM with 14.5 ns resolution eliminates companion logic, reducing BOM and PCB area for inverter designs.
Typical applications include industrial BLDC/PMSM servo drives, robotic actuators, HVAC compressor controllers, e-bike controllers, and appliance motor inverters. Designers also deploy it in digital power conversion such as solar micro-inverters and telecom rectifiers where the DSP MAC accelerates control-loop math.
Key design consideration: place the device's analog and digital ground returns as separate nets joining only at a single point near the AGND pin, since the on-chip ADC's 1.1 Msps performance is sensitive to digital switching noise injected through shared ground.

主な用途
DSPIC33FJ128MC710A-E/PF の用途: 6 件s: Brushless DC (BLDC) Motor Drive, Three-Phase Induction Motor Inverter, PMSM Servo Drive (Field-Oriented Control), Digital Switching Power Supply, Industrial Robot Arm Controller, Solar Micro-Inverter / Residential Energy Storage.
Brushless DC (BLDC) Motor Drive
The DSPIC33FJ128MC710A-E/PF fits BLDC motor drives because its six 14.5 ns-resolution PWM channels drive three-phase inverter legs with center-aligned switching up to ~50 kHz, while the DSP engine executes sensorless back-EMF or FOC commutation within a 25 us loop period. The 12-bit dual-sample-and-hold ADC samples two shunt currents simultaneously, eliminating phase-delay distortion. The 128 KB Flash holds state-machine tables, sinusoidal commutation LUTs, and a CANopen stack without external memory, and the two CAN modules enable multi-axis networked drives. Compared with a discrete MCU+FPGA solution, the integration reduces BOM by ~5 components and shrinks PCB to ~25 cm sq.
おすすめ
Three-Phase Induction Motor Inverter
For industrial three-phase induction motor control, the DSPIC33FJ128MC710A-E/PF runs V/F, open-loop scalar, or indirect FOC algorithms at the full 40 MIPS. The 16 KB SRAM accommodates Clarke-Park transforms, PI controller states, and sinusoidal encoder feedback buffers without forced off-chip memory access, eliminating cycle-stealing wait states. The 85 GPIOs drive gate-driver bootstrap control signals, brake-FET control, and isolated I/O for end-of-line and emergency stop circuits, leaving dual CAN available for industrial-bus communications. Thermal performance at +125 C junction extends to outdoor drive cabinets and aerospace actuator housings.
おすすめ
PMSM Servo Drive (Field-Oriented Control)
In PMSM servo drives the DSPIC33FJ128MC710A-E/PF executes full vector (FOC) current control plus position-velocity loop in software, with the DSP's single-cycle MAC running the inverse Park transform and SVPWM modulator in <5 us. The 1.1 Msps 12-bit ADC with dual-sample-and-hold captures Ia and Ib currents synchronized to the PWM reload, removing the settling-time error that plagues single-channel sampling. 16 KB SRAM holds the full observer state space (Back-EMF estimator or sliding-mode observer), allowing shaft-sensorless operation at zero speed. The two CAN modules support CANopen DS402 and EtherCAT-to-CAN bridge protocols in the same chip.
おすすめ
Digital Switching Power Supply
For digitally controlled SMPS the DSPIC33FJ128MC710A-E/PF's 40 MIPS enables sub-microsecond voltage-mode or current-mode control loops at switching frequencies up to 1 MHz. The 12-bit ADC with 1.1 Msps sampling and sub-100 ns trigger-to-conversion latency supports output-voltage sense plus primary-current sense in single-cycle sampling. Three of the six PWM channels deliver complementary gate-drive signals with programmable dead-time, eliminating the external gate-driver timing chip. The 128 KB Flash absorbs digital-compensation look-up tables, soft-start ramps, and PMBus firmware in a single chip, reducing BOM and improving reliability versus analog controller implementations.
おすすめ
Industrial Robot Arm Controller
In multi-axis robot-arm controllers the DSPIC33FJ128MC710A-E/PF drives one or two servo axes per chip with full FOC, leaving two on-chip CAN nodes to daisy-chain axes and an external EtherCAT/EtherNet/IP master. The 85 GPIOs handle encoder-A/B/Z inputs, end-stop sensors, and servo-driver enable signals without external glue logic. 40 MIPS throughput per axis sustains 8 kHz torque loop with quadratic observers fitting entirely in 16 KB SRAM. The -40 to +125 C operating range handles ambient temperatures inside sealed robot-arm enclosures where continuous current draw pushes components to thermal edges.
おすすめ
Solar Micro-Inverter / Residential Energy Storage
The DSPIC33FJ128MC710A-E/PF handles single-panel MPPT + DC-AC inversion in micro-inverter designs. Its DSP engine runs perturb-and-observe or incremental-conductance MPPT at <1 ms update with current-loop tracking inline, while the 12-bit ADC samples PV voltage and current plus output AC-current in single-cycle sampling. The 6 PWM channels drive interleaved boost MPPT plus full-bridge 60 Hz inverter; the second CAN enables parallel-string communications. The 128 KB Flash hosts grid-safety (anti-islanding), reactive-power control, and Modbus over RS-485 firmware stacks with margin.

設計ノート
Use a star-ground topology where the DSPIC33FJ128MC710A-E/PF's AVSS and VSS pins connect independently to a single-point ground near the voltage regulator return. Route analog signals away from PWM switching traces; place a 0.1 uF + 10 uF capacitor pair on AVDD within 5 mm of the package to suppress ADC sampling transients. Add a ferrite bead between VDD and AVDD if high-current digital outputs share AVDD rail current.
Do not exceed AVDD or VDD above 3.6 V or below 3.0 V; the dsPIC33F core is not 5 V tolerant. The MCLR pin must have a 10 kohm pull-up to VDD - leaving it floating produces erratic resets on EMC events. When running the PLL at 8x multiplier, ensure the input crystal or clock source has <50 ps RMS jitter, otherwise the DSP MAC timing becomes marginal above 35 MIPS sustained throughput.
For ADC sampling at >500 ksps, use the on-chip simultaneous dual-sample-and-hold mode (S/H triggered from PWM), not sequential scanning, which introduces phase delay between Ia and Ib reading that corrupts FOC current loops at >5 kHz rotation. Tie unused ADC inputs to AVDD or AVSS through 100 kohm resistors - floating inputs cause ADC offset drift and increased noise.
At 80 MHz FCY the DSPIC33FJ128MC710A-E/PF draws ~120 mA from 3.3 V = ~400 mW typical dissipation. The 100-TQFP package has junction-to-ambient theta_JA around 50 C/W (4-layer PCB); with +85 C ambient a 4 W internal budget gives only 15 C headroom. Provide 4-layer PCB with full copper pour under the exposed pad thermal tie, or use external airflow at >1 m/s for enclosed motor-inverter housings.
