DSPIC33FJ64GP310A-E/PT 概要
A digital signal controller combines the compute architecture of a microcontroller with the mathematical acceleration of a digital signal processor. Within the power-management hierarchy of embedded systems, the dsPIC33F sits between general-purpose MCUs and dedicated DSPs, integrating a 16-bit modified Harvard RISC core, DSP engine (multiply-accumulate, barrel shifter), and rich peripherals in a single chip. Microchip positions the dsPIC33FJXXXGPX10A family for applications that must execute digital filter algorithms and high-speed precision control loops.
Key features include the 40 MIPS core operating from an internal PLL, 64KB Flash with self-programming capability, an extensive analog portfolio (12-bit ADC with multiple sample-and-hold channels), and multiple UART, SPI, I2C, and CAN communication interfaces. According to the family datasheet (dsPIC33FJXXXGPX06A/X08A/X10A, published 2012-06-11), the device is pin compatible with the PIC24H family and shares a high degree of compatibility with the dsPIC30F family, enabling easy migration between device families.
The dsPIC33FJ64GP310A is Automotive AEC-Q100 graded per distributor listing data (Hotenda), making it suitable for harsh environments. The -E/PT ordering code denotes the extended temperature grade in the 100-TQFP tray package.
Typical applications include motor control (FOC, BLDC, PMSM), digital power supplies and inverters, automotive body and convenience modules, industrial sensing and instrumentation, and audio signal processing where DSP MAC instructions accelerate FIR/IIR filtering.
When designing, connect every VDD/VSS pin pair and pair PGECx/PGEDx correctly for ICSP programming - the device has multiple PGEC/PGED pairs and any pair works, but the pair must be used together.

主な用途
DSPIC33FJ64GP310A-E/PT の用途: 6 件s: Three-Phase Motor Control, Digital Power Supplies and Inverters, Automotive Body and Control Modules, Industrial Sensing and Instrumentation, Audio Signal Processing, Embedded Control and IoT Nodes.
Three-Phase Motor Control
The DSPIC33FJ64GP310A-E/PT fits motor control because Microchip engineered the dsPIC33F family specifically to execute high-speed precision digital control loops and digital filter algorithms. At 40 MIPS, the core runs field-oriented control (FOC) for BLDC and PMSM motors with PWM frequencies in the tens of kilohertz while leaving headroom for current-loop FIR/IIR filtering accelerated by the DSP multiply-accumulate engine. In a typical topology the controller generates complementary PWM pairs through external gate drivers, samples phase currents with its high-speed ADC, and closes the current and speed loops in software. The 100-pin TQFP provides abundant GPIO for encoder, Hall-sensor, and protection inputs, and the AEC-Q100 qualification plus -40C to +125C E-grade supports automotive traction and pump applications.
おすすめ
Digital Power Supplies and Inverters
The DSPIC33FJ64GP310A-E/PT is well suited to digitally controlled AC-DC, DC-DC, and solar-inverter stages because its 40 MIPS core and deterministic instruction timing support control-loop periods below 20 microseconds. The high-speed ADC samples voltage and current feedback near the PWM trip point, enabling peak-current-mode control, power-factor correction, and resonant-converter phase management entirely in firmware. The DSP MAC instructions accelerate compensator (PID/3p3z) and notch-filter computation with minimal cycle cost. In practice the device drives PWM outputs into isolated gate drivers while communicating setpoints and telemetry over UART, SPI, or I2C to a host. With the extended -40C to +125C grade and AEC-Q100 qualification, it also suits automotive on-board charger and industrial inverter environments where thermal margin is essential.
おすすめ
Automotive Body and Control Modules
With AEC-Q100 qualification and the -E extended temperature rating of -40C to +125C, the DSPIC33FJ64GP310A-E/PT addresses automotive body electronics, HVAC blowers, fuel-pump drivers, and lighting modules that see under-hood temperature excursions. The 100-pin package supplies the I/O count for multiple switch matrices, relay and LED outputs, and LIN/CAN-class communication channels needed in body controllers. Its 64KB Flash accommodates a full application plus bootloader, and self-programming capability supports field firmware updates. In a typical module the DSC reads sensor and switch inputs through filtered ADC channels, drives loads via low-side drivers, and reports diagnostics on the vehicle network. Designers should still verify the specific order code grade against the OEM's PPAP requirements before committing to production.
おすすめ
Industrial Sensing and Instrumentation
The DSPIC33FJ64GP310A-E/PT serves industrial data-acquisition nodes that must sample analog sensors, apply digital filtering, and stream results over serial links. Its ADC front end converts pressure, temperature, and current-sense signals, while the DSP engine performs noise rejection and linearization (look-up-table interpolation) at 40 MIPS - fast enough for kHz-rate control or condition-monitoring tasks. Multiple UART/SPI/I2C ports connect RS-485 transceivers, external precision ADCs, and local HMI displays simultaneously. The wide -40C to +125C operating range tolerates cabinet and rooftop installations, and the 3.3V supply simplifies integration with modern level translators. For front-end precision beyond the internal converter, pair the device with an external delta-sigma ADC over SPI to reach sub-millivolt measurement resolution in weigh scales and process transmitters.
おすすめ
Audio Signal Processing
The GP (general purpose) peripheral set of the DSPIC33FJ64GP310A-E/PT, combined with its DSP multiply-accumulate instructions at 40 MIPS, makes it practical for embedded audio functions: sample-rate conversion, biquad equalization, dynamic range compression, and simple active noise-control loops. The 100-pin device offers enough I/O to bit-bang or hardware-interface audio codecs over I2S-style serial links alongside control SPI/I2C. Its 64KB Flash holds coefficient tables and a modest filter chain; memory-heavy reverberation or multi-channel processing may warrant the 128KB/256KB pin-compatible family members instead, which is a key selection trade-off. Typical products include powered-speaker protection, automotive audio subsystem control, and pro-audio accessory processors where a full DSP is oversized and the E-grade thermal rating adds reliability margin.
おすすめ
Embedded Control and IoT Nodes
As a general 16-bit embedded controller, the DSPIC33FJ64GP310A-E/PT supervises pumps, valves, chargers, and networked sensor nodes that need more math throughput than a PIC18-class MCU. The 40 MIPS RISC core handles state machines and protocol stacks concurrently, while self-programmable 64KB Flash supports field-updatable firmware with a resident bootloader. Interfaces across the 100 pins connect to Ethernet/MAC-over-SPI modules, WiFi or LoRa radios over UART/SPI, and local sensing via I2C. The device is supported by the Explorer 16/32 Development Board with a PIM socket for fast prototyping, and ICSP via any PGECx/PGEDx pair simplifies in-system programming on the final board. For battery-powered designs, verify the low-power sleep currents against system budgets during design review.

設計ノート
Connect every VDD/VSS pin pair on the 100-TQFP - the dsPIC33FJ64GP310A has multiple supply pairs and omitting any decoupling causes brown-out resets and ADC noise. Place a 100 nF ceramic capacitor within 2 mm of each VDD pin plus one bulk 4.7-10 uF per supply domain. Per the family datasheet, the device is pin compatible with PIC24H, so reusing an existing PIC24H layout is feasible, but verify the AVDD/AVSS analog supply isolation and VCAP/VDDCORE connection against this die revision before fabrication.
ICSP programming uses paired clock/data pins: the device exposes multiple PGECx/PGEDx pairs, and per programming documentation (NSDSP summary) any pair works but the two pins of a pair must be used together - for example PGEC2 for ICSPCLK with PGED2 for ICSPDAT. Routing a programmer header to PGEC1/PGED3 will fail to connect. Reserve a 5-pin header (MCLR, VDD, GND, PGECx, PGEDx) on every production board and keep series resistors on PGD to allow sharing with application circuitry.
Estimated: budget the 3.3V rail using the 40 MIPS core current plus I/O load. With roughly 50-70 mA typical active core current at full speed (verify exact figure in the datasheet electrical characteristics table) plus 10-20 mA of I/O, a 150 mA headroom LDO such as the MCP1700-class parts is marginal - specify 250-300 mA capability. Add a ferrite bead plus 1 uF on AVDD to isolate the ADC reference from digital switching noise; measured noise on AVDD directly appears in ADC codes.
For motor-control or digital-power PWM outputs, route each PWM pair (high/low side) as matched-length traces to the gate drivers and keep the gate-drive loop away from analog sense lines. Use the remappable peripheral pin select (PPS) feature early in schematic capture to cluster digital functions on one side of the package and analog on the other, minimizing crossing under the ADC input traces. A solid ground plane under the TQFP with no splits beneath the ADC inputs gives the best effective-number-of-bits results.
