DSPIC33EP128MU206-H/MR 概要
A Digital Signal Controller combines the compute throughput of a DSP with the peripheral set and ease of use of a microcontroller. Within the power management hierarchy of embedded systems, the DSC sits between general-purpose MCUs and dedicated DSPs: it executes single-cycle MAC and DSP-enhanced instructions like a DSP, while retaining flash self-programming, rich timers, and communication peripherals typical of microcontrollers. The dsPIC33EP family is Microchip's high-performance 16-bit DSC generation, superseding the dsPIC33F series.
Key features include the 16-bit modified Harvard architecture with DSP engine, 128 KB flash and 16 KB RAM, a high-speed 12-bit ADC with multi-sample support, dual CAN 2.0B modules, USB 2.0 full-speed device capability, and multiple UART/SPI/I2C ports. The MU206 variant is distinguished by its USB and dual-CAN combination, which few other 64-pin dsPIC33EP parts offer, making it a natural fit for automotive and industrial gateway nodes.
Internally, the core achieves 70 MIPS at 3.3V with a 17-bit x 17-bit single-cycle hardware multiplier, 40-bit accumulator, and dual operands addressing for DSP kernels such as FIR filters and PID loops. Programmable PLL clocking allows low-cost crystals to synthesize the full-speed system clock.
Typical applications include motor control and power conversion, automotive gateways, USB-equipped industrial instruments, and digital power supplies where the 12-bit ADC feeds control loops at kHz rates.
For design, the -H/MR temperature grade (-40C to +125C) and thermally enhanced QFN exposed pad demand a solid ground pour; verify clock and PLL settings against the target MIPS before finalizing layout.

主な用途
DSPIC33EP128MU206-H/MR の用途: 6 件s: Motor Control (PMSM/BLDC FOC), USB-to-CAN Industrial Gateway, Digital Power Conversion, Automotive Subsystem Nodes, Portable and USB-Powered Instruments, Industrial Sensor Acquisition Nodes.
Motor Control (PMSM/BLDC FOC)
The dsPIC33EP128MU206-H/MR fits motor-control drives because its dedicated Motor Control PWM module produces complementary outputs with programmable dead time, while the 12-bit ADC samples phase currents synchronized to the PWM period - the exact topology required for field-oriented control. The 70 MIPS core with single-cycle 17x17 MAC executes Clarke/Park transforms and dual PI current loops comfortably at 20 kHz switching frequencies. In this application the DSC sits between gate drivers and the position sensor (encoder or resolver via QEI), closing torque loops in firmware. Design consideration: keep the ADC anti-aliasing filter and current-sense shunt layout close to the QFN pins, and exploit the -H grade (-40C to +125C) for hot drive enclosures.
おすすめ
USB-to-CAN Industrial Gateway
The MU206 is one of the few 64-pin dsPIC33EP parts combining a USB 2.0 full-speed device controller with dual CAN 2.0B modules, making it a natural single-chip bridge between a PC and two CAN buses. Typical firmware enumerates as a USB CDC device while running two independent CAN protocol stacks, with the 16 KB RAM buffering message queues and the 128 KB flash holding both stacks plus application logic. The 70 MIPS core leaves headroom for protocol translation (J1939, CANopen) without an external processor. Benefit: one chip replaces MCU + USB bridge + CAN controller, cutting BOM cost and board area in the 9x9 mm QFN.
おすすめ
Digital Power Conversion
In AC-DC and DC-DC converters the dsPIC33EP128MU206-H/MR implements voltage-mode or average-current-mode control digitally: the 12-bit ADC digitizes output voltage and inductor current, and the high-resolution PWM adjusts duty cycle each switching cycle. At 70 MIPS, control-loop update rates of 100 kHz and beyond are practical for LLC, boost-PFC, and synchronous-buck stages. The -H temperature grade suits power supplies inside sealed industrial enclosures reaching 125C ambient near hot components. Practical note: use the ADC interrupt-to-PWM trigger path (not polling) to keep control-loop jitter in the nanosecond range, and reserve flash headroom for firmware-field-upgrade routines.
おすすめ
Automotive Subsystem Nodes
Although not AEC-Q100 qualified in this exact suffix, the dsPIC33EP128MU206-H/MR's dual CAN 2.0B controllers, -40C to +125C grade, and 3.0-3.6 V supply align with many auxiliary automotive and off-highway electronic modules such as body controllers, pump controllers, and sensor aggregators. The 12-bit ADC reads analog sensor channels, timers generate PWM actuator drives, and both CAN ports link the node to vehicle networks - all in one chip. Designers targeting strict automotive qualification should verify the applicable PPAP-grade ordering options with Microchip, as commercial-grade dsPIC33EP parts may need formal qualification review before deployment in safety-relevant positions.
おすすめ
Portable and USB-Powered Instruments
For handheld test equipment, dataloggers, and USB accessories, the dsPIC33EP128MU206-H/MR offers full-speed USB device connectivity for data streaming and firmware update, while its DSP engine performs real-time FFT, filtering, or sensor-fusion math on the sampled data. The 12-bit ADC captures analog inputs at rates adequate for audio-band and industrial telemetry, and the 16 KB RAM holds ping-pong USB buffers plus DSP working arrays. Running from a single 3.3 V rail with modest peripheral current, the part integrates easily into battery-powered designs using a boost or LDO front end. The single-chip approach eliminates a separate USB-interface IC, saving board area in compact enclosures.
おすすめ
Industrial Sensor Acquisition Nodes
In distributed industrial monitoring, the dsPIC33EP128MU206-H/MR aggregates analog sensor channels through its 12-bit ADC (fronted by op-amp signal conditioning) and publishes processed values over UART, SPI, I2C, or CAN to a PLC or SCADA gateway. The 70 MIPS DSP engine applies digital filtering, RMS computation, or spectrum analysis locally, reducing bandwidth on the fieldbus and enabling edge decisions such as threshold alarms. The -H grade tolerates cabinet temperatures up to 125C, and the 128 KB flash accommodates firmware plus Modbus or CANopen stacks with room for field updates. The QFN-64 pin count supports multiple sensor channels plus two communication buses on one controller.

設計ノート
The /MR 64-QFN has a central exposed thermal pad that is the primary ground return. Define a solder-mask-defined window on the PCB with an array of thermal vias (typically 5x5, 0.3 mm drilled, plugged or tented) connecting to the internal ground plane. Without a solid pad connection, grounding of ADC references and CAN transceivers will be noisy and thermal performance degrades sharply. Follow Microchip's QFN layout appnotes for stencil aperture design (~70-80% coverage split into multiple apertures).
The device runs from a single 3.0-3.6 V rail. Decouple every VDD pin pair with 0.1 uF ceramics placed within 2 mm of the pins, plus one bulk 10 uF per supply group. If USB is used, the internal USB transceiver draws transient current during enumeration - provide local bulk capacitance and ensure the 3.3 V regulator can handle the combined core and USB load. Estimated: a typical running configuration draws a few tens of mA plus I/O loads; size the regulator for peak, not average, current.
Clock configuration is the most common bring-up failure: the PLL multiplier/divider must be programmed so the resulting Fcy does not exceed 70 MIPS (35 MHz instruction cycle at 3.3V, per family limits). Devices can lock up or draw excess current when over-clocked. Also confirm the correct ordering-code suffix before purchase - /MR (64-QFN) and /PT (TQFP-64) are electrically identical but NOT footprint-compatible, and -I vs -H temperature grades are not interchangeable in hot designs.
