DSPIC33EV32GM102-I/MM 概要
A digital signal controller combines the computational core of a digital signal processor (DSP) with the peripheral set and ease of use of a microcontroller (MCU). Within the power management hierarchy of embedded systems, a DSC sits between general-purpose MCUs and dedicated DSPs, offering multiply-accumulate (MAC) instructions and motor-control peripherals while retaining MCU-style flash, interrupts, and I/O. The dsPIC33EV family is Microchip's 5V-robust branch of this category, purpose-built for harsh electrical environments.
Key features include the 5V-tolerant 4.5V to 5.5V supply range, which eliminates the need for a separate 3.3V rail in automotive and industrial systems; 21 general-purpose I/O pins with Peripheral Pin Select (PPS) for flexible remapping; CAN, I2C, SPI, UART/USART, LINbus, and IrDA connectivity; and peripherals including DMA channels, motor-control PWM, brown-out detect/reset, power-on reset, and a watchdog timer.
The dsPIC33EV core integrates DSP engine features such as a 17-bit x 17-bit single-cycle hardware multiplier and dual 40-bit accumulators, enabling efficient execution of digital filters and field-oriented motor-control algorithms. Advanced analog integration, including on-chip op amps, SENT support, and a high-speed 12-bit ADC, reduces external component count in sensor and power-conversion front ends.
Typical applications include brushless DC and PMSM motor control, CAN-networked automotive body and powertrain nodes, industrial appliances, and switched-mode power supplies. The 5V noise immunity and wide -40C to +125C operating range (I temperature grade) make this device well suited to electrically noisy environments.
Design consideration: with only 32KB of Flash, budget code space carefully when adding a full CAN stack plus motor-control firmware; pin-to-pin larger-memory siblings in the same QFN-28 footprint provide an upgrade path without PCB redesign.

主な用途
DSPIC33EV32GM102-I/MM の用途: 6 件s: BLDC / PMSM Motor Control, Automotive CAN Network Nodes, Digital Power Supplies and Converters, Industrial Appliances, Sensor Signal Acquisition and Conditioning, Embedded Industrial Control and Automation.
BLDC / PMSM Motor Control
The DSPIC33EV32GM102-I/MM is purpose-built for brushless DC and permanent-magnet synchronous motor control: its motor-control PWM module generates complementary or independent PWM outputs with dead-time control, while the 70 MIPS DSP core with single-cycle 17x17 MAC executes field-oriented control (FOC) loops fast enough for high-speed drives. On-chip op amps amplify shunt current-sense signals, and DMA offloads ADC-to-PWM data paths to keep CPU load low. Because the 5V core tolerates the electrically noisy inverter environment directly, designers often skip level-shifting between the controller and gate-driver logic. The 32KB Flash is sufficient for a compact single-motor FOC stack with space for a small bootloader.
おすすめ
Automotive CAN Network Nodes
With its integrated CAN peripheral, 5V-tolerant I/O, and -40C to +125C operating range, the DSPIC33EV32GM102-I/MM fits automotive body-control, sensor-concentration, and actuator nodes that sit on a CAN bus. The 5V robustness directly addresses load-dump-adjacent transients common in 12V vehicle systems, and LINbus plus UART support covers lower-cost sub-networks alongside CAN. Peripheral Pin Select lets the CAN TX/RX pins be routed to the most convenient physical pins for the transceiver placement, simplifying PCB layout on space-constrained modules. The SENT peripheral further supports direct interfacing with SENT-protocol automotive sensors, reducing external signal-conditioning circuitry.
おすすめ
Digital Power Supplies and Converters
Switched-mode power supplies, PFC stages, and DC-DC converters benefit from the DSPIC33EV32GM102-I/MM's fast 12-bit ADC, flexible PWM with programmable dead time, and DSP throughput for compensation-loop math at 70 MIPS. The 5V core provides headroom against switching noise, and the on-chip op amps can condition current-shunt feedback without a separate amplifier stage, cutting BOM cost in cost-sensitive power designs. The 32KB Flash accommodates voltage-mode or average-current-mode control firmware with soft-start, protection state machines, and PMBus-style UART/I2C communication. Brown-out detect and watchdog peripherals add safety interlocking required in mains-powered conversion equipment.
おすすめ
Industrial Appliances
Microchip explicitly targets the dsPIC33EV family at harsh appliance environments, and the DSPIC33EV32GM102-I/MM delivers the combination these products need: a 5V noise-immune core for compressor and fan drives near relays and motors, PWM motor-control peripherals, and I2C/UART links to user-interface boards. The 32KB Flash is typically ample for a single appliance control law (washing-machine motor drive, HVAC blower, induction-heater control), while the watchdog timer and brown-out reset enforce safe recovery from mains disturbances. Surface-mount QFN-28 with exposed pad supports compact, thermally robust layouts on two-layer appliance control boards, keeping total system cost low.
おすすめ
Sensor Signal Acquisition and Conditioning
The on-chip 12-bit ADC, integrated op amps, and SENT support let the DSPIC33EV32GM102-I/MM condition and digitize analog sensor signals with minimal external circuitry. DSP instructions accelerate digital filtering (IIR/FIR) of raw ADC streams at up to 70 MIPS, improving effective resolution over the raw converter specification. Peripheral Pin Select allows flexible routing of SPI/UART links that stream processed data to a host ECU or gateway over CAN. This makes the device an economical intelligent sensor node for pressure, temperature, and position sensing in industrial and automotive systems where 5V sensor rails remain standard.
おすすめ
Embedded Industrial Control and Automation
In PLC-adjacent and machine-control applications, the DSPIC33EV32GM102-I/MM acts as a real-time control coprocessor: 21 I/O pins with remappable peripherals drive relays, read encoders, and communicate over CAN, SPI, or UART simultaneously. The DMA engine keeps multi-channel ADC sampling and PWM updates deterministic without CPU intervention, which matters for control-loop jitter. The 5V I/O connects directly to legacy 5V industrial sensors and logic without level translators - a persistent advantage over 3.3V Cortex-M parts in brownfield equipment. The QFN-28 6x6 footprint keeps controller area small on dense DIN-rail mounted boards.

設計ノート
The dsPIC33EV core requires a 4.5V to 5.5V supply with a nominal 5.0V. Place a 100nF ceramic decoupling capacitor at each VDD pin pair, as close to the package as possible, plus a 10uF bulk capacitor near the device. Because the exposed pad of the QFN-28 (MM) package is a thermal/electrical pad, solder it to a grounded copper pour to improve heat dissipation during 70 MIPS operation and to anchor the part mechanically. Avoid routing the 5V rail directly from switching loads; a ferrite bead plus local decoupling reduces conducted noise into the ADC reference.
The QFN-28 exposed-pad package requires a well-defined land pattern with via-fenced thermal pad (typical 4-6 via array) to the ground plane for reliable reflow soldering. Peripheral Pin Select (PPS) lets you place the CAN transceiver, SPI, and UART on the most layout-convenient RPn pins - finalize PPS mapping before routing to avoid cross-board jumpers. Keep the on-chip op-amp input traces short and guard them with ground pour when sensor signals are in the millivolt range. Reference Section 11.5 'Peripheral Pin Select' of the family data sheet (DS70005144H) for mapping limitations.
Verify the full MPN suffix when ordering: GM102 includes CAN while GM002 omits it, and the -I grade tops out at +125C versus +150C for the -H grade - a mismatch discovered after layout is costly. Flash is 32KB (11K x 24 instruction words); budget a CAN/J1939 stack plus FOC firmware carefully and keep a 64KB/128KB same-footprint upgrade path in the BOM qualification. MCLR programming requires the proper ICSP header (PGEC/PGED pairs); do not repurpose these pins without preserving a programming access route.
