DSPIC30F4011T-30I/ML 概要
A Digital Signal Controller (DSC) is a hybrid between a microcontroller (MCU) and a digital signal processor (DSP). DSCs such as the dsPIC30F4011 combine deterministic interrupt-driven MCU peripherals with a single-cycle MAC DSP engine, allowing control algorithms (PI/PID, space-vector modulation, Kalman filtering, FFT) to execute in hardware-firmware co-design without a separate DSP chip. Within the broader hierarchy, the dsPIC30F sits under DSC -> microcontroller -> embedded processor -> semiconductor.
Key features of the DSPIC30F4011 include a 30 MIPS modified Harvard architecture core, 48KB Flash with 4KB boot Flash, 2KB RAM, 1KB EEPROM, 30-channel 10-bit ADC @ 1 Msps, dedicated motor-control PWM (6-channel, complementary outputs with 14-bit resolution), 4-channel 16-bit timers, quadrature encoder interface, CAN 2.0B, I2C, SPI, UART (with IrDA), and a 16-bit parallel slave port for external memory or FPGA connectivity. The DSP engine executes one MAC per instruction cycle.
Architecturally, the DSPIC30F4011 uses a 16-bit native datapath with a 24-bit instruction word, providing high code density while preserving DSP precision. The device operates from industrial-grade -40C to +85C, includes a 5V-tolerant digital I/O bus for legacy mixed-signal designs, and provides on-chip oscillator support with PLL up to 120 MHz. The DSP engine with dual 40-bit accumulators enables single-cycle MAC and barrel-shifter operations.
Typical applications include BLDC/PMSM/switched-reluctance motor control (sensored and sensorless), uninterruptible power supplies (UPS), digital power conversion (PFC, LLC, full-bridge), variable-frequency drives (VFDs), sensorless field-oriented control (FOC), automotive actuator control, and industrial servo drives. The 6-channel PWM plus QEI make it particularly suited to three-phase inverter control.
When designing with this device, allocate the 30 MIPS budget explicitly: DSP routines such as Clarke/Park transforms and SVPWM typically consume 8-12 MIPS; the remainder handles control loops and communication. Always validate MCU clock vs. ADC/PWM timing constraints in the electrical characteristics section of the manufacturer datasheet before committing to PWM frequency.

主な用途
DSPIC30F4011T-30I/ML の用途: 7 件s: BLDC / PMSM Motor Control, Digital Power Conversion (PFC, LLC, Full-Bridge), Uninterruptible Power Supplies (UPS), Variable-Frequency Drives (VFDs) and Servo Drives, Sensorless Field-Oriented Control (FOC), Automotive Actuator and Pump Control, Industrial Sensor Signal Processing.
BLDC / PMSM Motor Control
The DSPIC30F4011T-30I/ML is purpose-built for three-phase brushless DC and permanent-magnet synchronous motor control, integrating a 6-channel 14-bit PWM module with complementary outputs and programmable dead-time, plus a quadrature encoder interface for rotor-position feedback. Its 30 MIPS DSP engine executes Clarke/Park transforms and space-vector PWM in a single cycle, leaving ample MIPS for FOC loops running at 20-40 kHz. The 10-bit 1 Msps ADC samples phase currents within the PWM cycle for precise torque control.
おすすめ
Digital Power Conversion (PFC, LLC, Full-Bridge)
Digital power supplies benefit from the DSPIC30F4011T-30I/ML's DSP engine, which implements average-current-mode control, peak-current-mode control, and adaptive dead-time compensation in firmware. The 30 MIPS budget supports a 100 kHz control loop with margin for soft-start, MPPT, and telemetry. The high-resolution 14-bit PWM module with 7.4 ns resolution provides fine-grained duty-cycle adjustment for PFC and LLC topologies, while 5V-tolerant I/O simplifies gate-driver interface.
おすすめ
Uninterruptible Power Supplies (UPS)
A UPS inverter controller benefits from the DSPIC30F4011T-30I/ML's deterministic interrupt latency and DSP performance, which generate 50/60 Hz sine PWM with low total harmonic distortion (THD typically <3%) under varying load. The on-chip CAN 2.0B peripheral enables UPS-to-UPS communication and remote monitoring, while UART supports Modbus RTU to SCADA systems. The 2 KB RAM is sufficient for waveform lookup tables and state-machine control.
おすすめ
Variable-Frequency Drives (VFDs) and Servo Drives
The DSPIC30F4011T-30I/ML's integrated quadrature encoder interface, 6-channel PWM with dead-time control, and 30 MIPS DSP throughput make it a single-chip solution for industrial variable-frequency drives controlling induction motors and servo systems. Closed-loop torque control runs at 16 kHz; speed and position loops run at 4 kHz with ample MIPS margin. The CAN 2.0B interface supports CiA 402 servo drive profiles, enabling networked multi-axis motion control.
おすすめ
Sensorless Field-Oriented Control (FOC)
Sensorless FOC motor control relies on the DSPIC30F4011T-30I/ML's ADC and DSP to estimate rotor position from back-EMF or sliding-mode observers. The 30 MIPS budget supports a sliding-mode observer at 20 kHz plus the FOC loop at the same rate, with room for space-vector modulation and weak-field-weakening regions. The DSP's single-cycle MAC keeps the estimator inner loop under 5 microseconds, enabling smooth low-speed torque control down to 5% of rated speed.
おすすめ
Automotive Actuator and Pump Control
Although the DSPIC30F4011T-30I/ML is industrial-grade (-40C to +85C), its 5V-tolerant I/O and CAN 2.0B peripheral make it well-suited to 12V automotive actuator systems such as water pumps, oil pumps, and HVAC blowers. The QFN package provides good thermal performance for under-hood or chassis-mounted enclosures. Designers should evaluate the AEC-Q100 requirements carefully; for AEC-Q100 qualified parts, choose dsPIC33F or PIC32 automotive variants.
おすすめ
Industrial Sensor Signal Processing
The DSPIC30F4011T-30I/ML's 16-bit DSP engine and 30 MIPS throughput enable on-chip digital filtering, FFT analysis, and PID control for industrial sensors such as load cells, pressure transducers, and flow meters. Its 5V analog and digital I/O interface directly with legacy 4-20 mA transmitters and bridge sensors without level shifters, while the CAN 2.0B peripheral publishes processed data to plant networks.

設計ノート
Estimated: at 30 MIPS in 44-QFN (theta_JA approximately 28 C/W on JEDEC 4-layer test board), full-load DSP activity, and 5V supply, the junction temperature rise above ambient is roughly 8-10 C. The QFN's exposed pad must be soldered to a ground pour of at least 1 square inch for the thermal specification to hold. In enclosed motor-drive enclosures with limited airflow, consider heatsinking the PCB or de-rating ambient spec.
The 44-QFN exposed pad (EP) is the primary thermal and electrical ground return for the dsPIC30F4011; it must be soldered to a low-impedance ground plane using an array of thermal vias (8-12 vias, 0.3 mm diameter) to inner layers. Place 100 nF decoupling capacitors on every VDD/VSS pair within 5 mm of the pins, plus 10 uF bulk capacitors near the package. Keep analog AVSS traces separate from noisy digital VSS until they join at the ground plane.
Route the 30 MHz external crystal traces (OSC1/OSC2) symmetrically with guard traces to ground; keep total trace length under 5 mm. Analog ADC inputs (AN0-AN5, AN8-AN13) must be isolated from digital switching traces; do not cross or route parallel to PWM outputs. Use a ferrite bead or pi-filter on AVDD to reduce switching noise coupling into the ADC reference. For sensorless motor control, route current-sense traces as a matched pair (Kelvin connection) to the ADC.
Do not exceed the 5.5V absolute maximum on any I/O pin; the dsPIC30F4011 is 5V tolerant only within the operating range and is damaged above 5.5V. The MCLR pin must have a 10 kohm pull-up to VDD for normal operation; do not leave it floating. Configuration bits must be set before code execution; an unconfigured device will execute only the default bootloader. Use ICSP pins PGEC1/PGED1 as the programming interface and never wire them to other signals during programming.
