DSPIC33FJ64MC710AT-I/PT 概要
A digital signal controller combines the compute architecture of a microcontroller with the DSP engine of a digital signal processor. In the power-management hierarchy, the dsPIC33F family sits between general-purpose MCUs (such as the PIC24) and dedicated DSPs, adding a DSP multiply-accumulate engine, 8-channel DMA, and motor-control-specific peripherals (PWM with dead-time insertion, quadrature encoder interface) to a familiar MCU toolchain.
Key features include a 16-bit dsPIC33F core executing up to 40 MIPS, 64KB self-programmable Flash with in-circuit programming, and 16KB data RAM. The device integrates a 10-bit high-speed ADC, multiple UART, SPI and I2C serial ports, CAN 2.0B for industrial networking, and DMA channels that offload data movement from the CPU. According to Microchip product pages, the family targets brushless DC, single and 3-phase induction, and switched reluctance motor control.
Technical depth: the dsPIC33FJ64MC710A core supports 40 MHz maximum clock operation (40 MIPS at 3.3V supply), with DSP instructions including 40-bit accumulators, dual operand fetch, and modulo/bit-reversed addressing. The 8-channel DMA and nine timers support deterministic real-time control loops, while the Output Compare/PWM modules generate complementary waveform pairs for inverter bridges. Per the Microchip USA listing, the related ATH grade variant is built on CMOS technology meeting AEC-Q100 automotive requirements.
Typical applications include brushless DC (BLDC) and PMSM motor drives, solar inverters, digital UPS and power-factor-correction converters, and industrial automation nodes requiring CAN connectivity alongside DSP-class control loops.
Design consideration: at 40 MIPS the device is sensitive to supply integrity; place 0.1 uF decoupling at all VDD/VSS pairs and keep the switching nodes of the power stage away from the analog front end to protect ADC accuracy.

主な用途
DSPIC33FJ64MC710AT-I/PT の用途: 6 件s: Brushless DC (BLDC) Motor Drives, Solar Inverters and MPPT Converters, Uninterruptible Power Supplies (UPS), Industrial Automation and CAN Networking Nodes, Switched Reluctance and Induction Motor Control, Digital Power Supplies and PFC Converters.
Brushless DC (BLDC) Motor Drives
The DSPIC33FJ64MC710AT-I/PT is purpose-built for BLDC control: its complementary PWM outputs with programmable dead time drive a three-phase inverter bridge directly, while the high-speed 10-bit ADC samples phase currents and the DC bus for closed-loop commutation. The 40 MIPS DSP engine executes trapezoidal or field-oriented control (FOC) algorithms with deterministic latency, supported by 8 DMA channels that transfer ADC results without CPU intervention. The quadrature encoder interface or sensorless back-EMF estimation provides rotor position feedback. With 64KB Flash, sensorless FOC plus a CAN or UART host protocol fits comfortably in program memory, and the -40C to +85C industrial rating covers factory floor environments.

Solar Inverters and MPPT Converters
In grid-tied and off-grid solar inverters, the DSPIC33FJ64MC710AT-I/PT performs maximum power point tracking (MPPT), DC-DC stage control, and DC-AC modulation in a single 40 MIPS controller. Its 10-bit ADC, boosted by DMA, samples PV voltage, current, and grid waveforms fast enough for perturb-and-observe or incremental-conductance MPPT loops running in parallel with PWM generation. Complementary PWM outputs with dead-time insertion drive the power stage safely, and the CAN 2.0B module links the inverter to plant monitoring networks. The 100-pin TQFP provides ample I/O for gate-drive isolation control, relays, and protection sensing, while 64KB Flash stores MPPT algorithms plus communication stacks.
おすすめ
Uninterruptible Power Supplies (UPS)
The dsPIC33FJ64MC710A family is explicitly identified by Microchip as well-suited for uninterruptible power supply applications. In a digital UPS, the DSPIC33FJ64MC710AT-I/PT controls the AC-DC rectifier, battery charger, and DC-AC inverter stages with its complementary PWM modules, while the 10-bit ADC and DMA monitor battery voltage, current, and output waveform quality. Its 40 MIPS DSP throughput executes sinusoidal reference generation and closed-loop voltage regulation in real time, and the 100-pin TQFP supplies enough I/O for bypass relay control, LCD interface, and multi-input protection logic. UART connectivity supports SNMP or RS-232 management cards common in rack UPS systems.
おすすめ
Industrial Automation and CAN Networking Nodes
For industrial automation nodes, the DSPIC33FJ64MC710AT-I/PT combines a CAN 2.0B controller with UART, SPI, and I2C ports on a 40 MIPS 16-bit core, letting one device run a real-time control loop and fieldbus communication simultaneously. Its 8 DMA channels stream sensor data and communication buffers without CPU overhead, and nine timers coordinate event scheduling across actuators and sensors. The 100-pin TQFP exposes abundant GPIO for digital I/O banks, encoder inputs, and analog front ends, making the part suitable for motion controllers, process sensors, and distributed I/O modules on factory networks. The -40C to +85C rating withstands panel-mounted industrial conditions.
おすすめ
Switched Reluctance and Induction Motor Control
Beyond BLDC drives, Microchip identifies the dsPIC33FJ64MC710A family for single and 3-phase induction motors and switched reluctance (SR) motors. For induction control, the 40 MIPS DSP core runs V/Hz or sensorless vector algorithms using its 40-bit accumulator DSP instructions, while complementary PWM pairs with dead time drive IGBT or MOSFET bridges. SR motor control benefits from precise ADC sampling of phase currents and flexible PWM shaping to handle the torque-ripple-sensitive commutation of SR machines. The quadrature encoder interface supports closed-loop speed feedback, and 16KB RAM accommodates control states plus modest communication buffering without external memory.
おすすめ
Digital Power Supplies and PFC Converters
In digital power supplies, power factor correction stages, and DC-DC converters, the DSPIC33FJ64MC710AT-I/PT replaces analog control loops with firmware: its high-speed 10-bit ADC plus 8-channel DMA samples input/output voltage and inductor current each switching cycle, and the PWM module adjusts duty cycle at 40 MIPS response speed. Complementary outputs with programmable dead time suit half-bridge and full-bridge topologies, and the CAN/UART links enable digital telemetry to system controllers. The 100-pin TQFP supports multi-rail designs needing many feedback and sequencing signals. For SMPS-dedicated features, Microchip's dsPIC33FJ64GS610 digital power family is a migration path in the same toolchain.

設計ノート
The dsPIC33FJ64MC710A operates from a single 3.3V supply. Decouple every VDD/VSS pair of the 100-pin TQFP with a 0.1 uF ceramic capacitor placed within 2 mm of the pin, and add bulk capacitance (10-47 uF) near the device. Because the 40 MHz core switches all I/O simultaneously during PWM updates, ground bounce on shared VSS pins can corrupt ADC readings - use a solid ground plane rather than ground traces, and separate the analog supply path with an LC filter or ferrite bead if ADC accuracy is critical to your control loop.
In motor drive and inverter boards, keep the high dv/dt switching nodes and gate-drive return paths away from the dsPIC's analog inputs and crystal/oscillator traces. Route the phase-current sensing lines differentially or as short shielded runs to the ADC pins, and place the reference (VREF) decoupling directly at the pins. For the 0.5 mm pitch 100-TQFP, use NSMD pads with solder-mask defined dams to prevent bridging, and design an inspection-friendly fanout - escape at least one via per signal on inner layers to simplify rework of this high-pin-count controller.
Check the Microchip silicon errata document for your device revision before finalizing firmware - the dsPIC33FJ64MC710 family has published errata affecting peripheral behaviors, and the 'A' revision (DSPIC33FJ64MC710A) addresses many of them. Also mind programming voltage and debug-tool compatibility: this family programs via ICSP with tools such as ICD 3/PICkit series, and MCLR must not be tied directly to VDD without the recommended resistor network, or in-circuit programming will fail. Plan Flash endurance for applications with frequent self-write logging.
