DSPIC33FJ64GP310AT-I/PT 概要
A Digital Signal Controller combines the compute engine of a microcontroller with DSP capability - a 16-bit modified Harvard architecture with a DSP instruction set, hardware multiply-accumulate (MAC), barrel shifter, and fast interrupt handling. In the system hierarchy, the DSC sits between a general-purpose MCU (such as the PIC24) and a dedicated DSP, and the dsPIC33F family offers seamless migration to PIC24F, PIC24H MCUs and dsPIC30F DSCs in similar packages.
Key features include 40 MIPS operation at 3.0-3.6V, an industrial temperature rating of -40C to +85C (I suffix), and In-Circuit Serial Programming (ICSP) via PGECx/PGEDx pins for field programming and debugging. The device integrates general-purpose peripherals typical of the dsPIC33FJXXXGPX10 family, including UART, SPI, I2C and ADC resources for mixed analog-digital designs.
Architecturally, the dsPIC33F core executes C compiler-friendly code with DSP extensions, supporting both control loops and signal-processing tasks - such as FIR/IIR filtering - in a single chip. CMOS process technology keeps power manageable, and low-power modes support battery-adjacent designs.
Typical applications include industrial control, motor control and power conversion, automotive subsystems, consumer electronics, and medical devices - domains explicitly cited by distributors for this part.
Design consideration: supply the 3.0-3.6V rail with proper decoupling on all VDD/VSS pairs, and route ICSP programming pins to a header for in-system updates.

主な用途
DSPIC33FJ64GP310AT-I/PT の用途: 6 件s: Industrial Control and Automation, Motor Control and Power Conversion, Automotive Subsystems, Consumer Electronics, Medical Devices and Diagnostics, Test, Measurement and Data Acquisition.
Industrial Control and Automation
The DSPIC33FJ64GP310AT-I/PT is engineered for industrial control, a domain explicitly cited by distributors for this part. Its 40 MIPS 16-bit core executes PID loops and sequencing logic with deterministic interrupts, while 64KB FLASH accommodates protocol stacks (Modbus, CAN-based schemes) and 16KB RAM buffers sensor data. The -40C to +85C industrial temperature rating survives cabinet environments without component derating, and the 100-pin TQFP exposes enough I/O for relays, encoders, and multiple UART/SPI/I2C channels. Used as the main controller between field sensors and actuators, its DSP MAC instructions offload filtering tasks that would otherwise require a companion DSP, reducing board cost and firmware complexity in PLC-style nodes and process-control equipment.
おすすめ
Motor Control and Power Conversion
Digital motor control demands fast deterministic math - exactly what the dsPIC33F's hardware multiply-accumulate and barrel shifter provide. At 40 MIPS, the DSPIC33FJ64GP310AT-I/PT computes space-vector modulation and current-loop compensation at PWM-carrier rates, while its ADC resources sample phase currents synchronously. The 3.0-3.6V supply and CMOS process keep gate-drive interface logic simple, and the 100-pin TQFP offers sufficient PWM outputs and communication ports (UART/SPI) for driving inverters in HVAC blowers, pumps, and small servo drives. Compared with a pure MCU, the integrated DSP engine removes the need for an external DSP chip, cutting BOM cost while sustaining the loop bandwidth required for smooth torque control.
おすすめ
Automotive Subsystems
Distributor data explicitly lists automotive among the target applications for the DSPIC33FJ64GP310AT-I/PT. In 12V-vehicle environments the controller typically sits behind a regulated 3.3V rail, using its -40C to +85C rating to cover passenger-compartment and under-dash conditions. The 64KB FLASH holds LIN/CAN-style communication stacks and diagnostic routines, while the DSP engine handles sensor signal conditioning such as averaging and notch filtering on noisy analog inputs. Its ICSP pins (PGECx/PGEDx) allow end-of-line reprogramming on the production fixture. Typical uses include body-control nodes, sensor hubs, and small actuator controllers where a full automotive-qualified MCU is unnecessary but robust 16-bit processing is still required.
おすすめ
Consumer Electronics
In consumer products the DSPIC33FJ64GP310AT-I/PT balances cost and capability: 64KB FLASH supports feature-rich firmware, while the 3.3V single-rail supply simplifies power-tree design alongside common consumer ICs. Applications include appliance control panels, small displays and user interfaces, battery chargers with smart algorithms, and audio accessory processing, where the DSP MAC unit performs equalization or tone-control filtering without an external codec DSP. The 100-pin TQFP provides the I/O breadth needed for keypads, LED matrices, and multiple serial peripherals in one chip, reducing PCB layer count. Its active lifecycle and multi-distributor availability (DigiKey ships today per listing) also de-risk ongoing production for consumer product lifecycles.
おすすめ
Medical Devices and Diagnostics
Medical device classifications cited by distributors for this part include portable diagnostics and monitoring equipment. The DSPIC33FJ64GP310AT-I/PT's 16-bit ADC path and DSP instructions support biopotential filtering (ECG/EMG-style IIR and FIR chains) at deterministic latency, while 64KB FLASH stores calibration tables and communication firmware for USB/UART links to host systems. The 100-pin TQFP integrates enough GPIO to multiplex sensor arrays and drive displays in handheld instruments, and low-power modes extend battery life in portable designs. Designers should implement proper isolation and follow applicable medical electrical safety standards in the surrounding system; the controller itself provides the deterministic compute core and in-field firmware update capability via ICSP.
おすすめ
Test, Measurement and Data Acquisition
Bench and embedded data-acquisition systems benefit from the DSPIC33FJ64GP310AT-I/PT's combination of synchronous ADC sampling and fast post-processing. The barrel shifter and MAC accelerate windowing and decimation filters ahead of UART or SPI transmission to a host PC, and 16KB RAM supports multi-channel sample buffering. The 100-pin TQFP dedicates generous I/O to parallel sensor interfacing, relays, and front-panel controls, while boundary-scan support aids production test of the assembled board. Because the family is supported long-term by Microchip with the XC16 toolchain and MPLAB X debugging over PGECx/PGEDx, instruments built around this DSC can be serviced and firmware-updated across a multi-year field lifetime.

設計ノート
Provide a clean 3.0-3.6V rail with a 0.1uF ceramic decoupling capacitor at every VDD/VSS pair of the 100-pin TQFP, plus bulk 10uF near the supply entry. The full 40 MIPS rating is only guaranteed across the entire 3.0-3.6V operating range per the datasheet, so avoid marginal LDOs that sag below 3.0V under load transients. All I/O is 3.3V logic - level-shift any 5V peripheral interfaces.
Route one PGECx/PGEDx pair from the microcontroller to a 5-pin ICSP header (MCLR, VDD, GND, PGEC, PGED) at the board edge for in-circuit programming and debugging, per the datasheet ICSP pins section. Keep crystal traces (OSC1/OSC2) short and guard them with ground. The 12x12 mm TQFP has 0.5 mm pitch - specify a solder-mask-defined land pattern per Microchip's package outline drawing and inspect with AOI for bridging.
The '/PT' suffix means Tape & Reel packaging - order the correct suffix for your pick-and-place process. Do not confuse the AT (revised) part with the base 310A part when qualifying: verify the exact temperature suffix (-I industrial vs -E extended) on incoming labels. MCLR must be pulled up (typically 10k to VDD) and never driven above the rail, or programming and normal reset behavior will be compromised.
Estimated: the dsPIC33F at 40 MIPS with peripherals enabled typically draws tens of milliamps at 3.3V (on the order of 100-200 mW), so junction temperature rise over ambient in the 100-TQFP is small and no heatsink or thermal pad is required. Nevertheless, allow natural convection around the 12x12 mm body and avoid placing the device adjacent to hot power components in motor-drive layouts to protect long-term reliability.
