DSPIC33FJ64MC710AT-I/PF 概要
A digital signal controller combines the computational power of a DSP with the peripheral integration and control architecture of a microcontroller, sitting in the system hierarchy between a general-purpose MCU and a dedicated DSP chip. DSCs are optimized for control loops that need fast multiply-accumulate operations, such as field-oriented motor control, digital power conversion, and sensor signal processing.
Key features include the dsPIC 16-bit core running at 40 MIPs, 8-channel DMA for low-CPU-overhead data movement, 9 timers, and 4 dedicated serial I/O ports. Connectivity is extensive: CANbus, I2C, IrDA, LINbus, SPI, and UART/USART interfaces cover automotive networking, industrial field buses, and general serial links. The CMOS process keeps power draw reasonable at full clock speed.
Architecturally, the dsPIC33F core pairs a pipelined 16-bit MCU datapath with DSP-engine instructions (MAC, dual operand fetch), enabling deterministic single-cycle multiply-accumulate within the control ISR. Multiple PGECx/PGEDx pin pairs support in-circuit serial programming (ICSP); PGEC2 must be paired with PGED2 when used for ICSPCLK/ICSPDAT.
Typical applications include brushless DC motor control, single- and 3-phase induction motor drives, switched reluctance motor systems, digital power supplies, and CAN-networked industrial nodes - exactly the use cases Microchip targets with the dsPIC33FJ64MC710A family.
Design-wise, plan pin selection early: because multiple PGECx/PGEDx pairs exist, choose one pair and route it to the programming header during layout to avoid costly respins.

主な用途
DSPIC33FJ64MC710AT-I/PF の用途: 6 件s: Brushless DC Motor Control, 3-Phase Induction Motor Drives, Switched Reluctance Motor Systems, CAN-Networked Industrial Nodes, Digital Power Conversion, General Embedded Control with DSP.
Brushless DC Motor Control
The dsPIC33FJ64MC710A family is explicitly targeted by Microchip at brushless DC (BLDC) motor applications. The 40 MIPS dsPIC core executes commutation and field-oriented control algorithms using single-cycle multiply-accumulate instructions, while the 8 DMA channels move ADC current-sampling results to RAM without CPU intervention, keeping the current loop deterministic even at high PWM frequencies. The 9 timers generate complementary PWM outputs with dead-time insertion for the three-phase inverter. The AT-I/PF industrial temperature rating of -40C to +85C suits factory automation drives, and the CAN interface lets the motor controller join a higher-level automation network without an additional CAN controller chip.
おすすめ
3-Phase Induction Motor Drives
Single- and 3-phase induction motor control is a listed target application of the dsPIC33FJ64MC710A family per the Microchip product page. The 40 MIPs, 16-bit core provides the headroom for voltage/frequency control or sensorless field-oriented control, and the DSP engine handles the coordinate transforms efficiently. Abundant UART/USART and LINbus interfaces support human-machine-interface panels and industrial field wiring, while the 8-channel DMA services ADC feedback in the background. The 64KB FLASH accommodates full V/Hz and FOC firmware stacks with diagnostics, and the 100-TQFP package supplies enough I/O for gate-driver control, encoder/Resolver feedback and safety interlocks in one controller.
おすすめ
Switched Reluctance Motor Systems
Microchip lists switched reluctance (SR) motor control among the dsPIC33FJ64MC710A family target applications. SR drives demand precise, asymmetric phase-current profiling and rapid torque reversal - tasks that benefit from the dsPIC33F core's deterministic interrupt response and single-cycle MAC math. The 9 timers support multi-channel PWM phase excitation, and the 4 serial I/O ports plus CAN/I2C/SPI/UART connectivity integrate the drive into factory networks. The 16KB RAM buffers phase-current waveforms for diagnostic analytics via DMA. With the AT-I/PF rated -40C to +85C in CMOS at 3.3V, the part suits industrial SR pumps, compressors, and fans where sensorless control reduces BOM cost.
おすすめ
CAN-Networked Industrial Nodes
With integrated CANbus alongside I2C, SPI, UART/USART, IrDA and LINbus, the DSPIC33FJ64MC710AT-I/PF serves as a single-chip gateway and control node on CAN-based industrial networks. The CAN peripheral handles frame buffering autonomously, while the 8 DMA channels stream sensor data from SPI or UART peripherals into the 16KB RAM without CPU loading. The 4 serial I/O ports allow simultaneous bridge operation - for example CAN-to-RS485 protocol conversion - within one 40 MIPs controller. The 100-TQFP provides ample I/O for local relays and sensors, and the -40C to +85C rating covers unconditioned factory-floor enclosures per the Microchip USA product data.
おすすめ
Digital Power Conversion
The dsPIC33F Motor Control family is well-suited for digital power supplies, PFC stages and inverters, per Microchip product documentation. The 40 MIPS core closes voltage and current loops fast enough for 100+ kHz switching stages, the ADC-DMA-PWM interconnect achieves minimal sample-to-update latency, and the 9 timers generate phase-shifted or complementary PWM topologies. 64KB FLASH holds compensation networks, soft-start state machines, and PMBus/UART telemetry in one image. The 3.3V CMOS device interfaces directly with gate-driver logic, and the 100-TQFP 14x14 mm body fits standard half-bridge power-board footprints, making the AT-I/PF a strong fit for server and telecom power stages.
おすすめ
General Embedded Control with DSP
Beyond motors and power, the DSPIC33FJ64MC710AT-I/PF fills the gap between general-purpose PIC24 MCUs and dedicated DSPs in applications such as sensor signal processing, audio processing, and instrumentation front ends. The 16KB RAM and 8 DMA channels support continuous block-based filtering (FIR/IIR) of sensor streams, while UART/IrDA/SPI/I2C cover legacy field interfaces and IrDA-enabled handheld links. Multiple PGECx/PGEDx pairs enable convenient in-circuit reprogramming in deployed systems - just remember ICSPCLK and ICSPDAT must come from the same PGEC/PGED pair. At 3.3V, 40 MIPs and -40C to +85C, it consolidates signal chain plus control into a single 100-pin device.

設計ノート
The dsPIC33FJ64MC710 has more than one PGECx/PGEDx programming pair, and ICSP requires matched pairs: if PGEC2 carries ICSPCLK, ICSPDAT must connect to PGED2. Mixing pins across pairs is one of the most common bring-up failures and typically manifests as a programming-voltage verification error. Route the selected pair to a 5-pin ICSP header (MCLR, VDD, GND, PGECx, PGEDx) during initial PCB layout rather than relying on bed-of-nails fixtures, which struggle with the 14x14 mm TQFP pin pitch.
The device runs from a 3.3V nominal CMOS supply. Provide independent decoupling: at least one 100 nF ceramic directly at each VDD/VSS pin pair plus 4.7-10 uF bulk capacitance near the corner supply entries of the 100-TQFP. When switching from a 5V system bus, use a proper LDO or buck regulator with adequate transient response - DMA bursts driving all serial ports and PWM simultaneously create fast load transients. Verify actual 40 MHz operating current against the datasheet current-consumption tables rather than estimating from idle figures.
For motor-control use, keep the ADC input traces (current-shunt feedback) short, symmetric, and away from the PWM gate-driver nets to minimize crosstalk into current-loop sampling; use the device's simultaneous-sampling capability and DMA ping-pong buffers so the control ISR operates on a coherent sample set. Ground the exposed thermal behavior of the TQFP with a solid internal ground plane and multiple stitching vias. Reserve the CAN bus with proper split termination and place the transceiver within 20 mm of the CAN TX/RX pins for signal integrity at 1 Mbps.
コンプライアンス情報
The provided verified data does not state RoHS/REACH/lead-free status for this MPN specifically; Microchip typically marks commercial dsPIC33FJ parts as RoHS-compliant, but this must be confirmed on the Microchip product page. The AEC-Q100 qualified variant is the DSPIC33FJ64MC710ATE/PF, not this part.
