DSPIC33EP128MU202T-I/MM 概要
A digital signal controller combines the peripherals and ease-of-use of a microcontroller with the computational throughput of a digital signal processor. Within Microchip's portfolio, the dsPIC33E family sits between general-purpose 16-bit PIC24 MCUs and high-performance 32-bit MCUs, offering single-cycle MAC, DSP multiply-accumulate instructions, and dual 40-bit accumulators, making it a power management IC-controller class device for real-time control systems.
Key differentiating features include the integrated USB 2.0 Full-Speed module (a capability the pin-compatible GP and MC variants lack), dual I2C, dual SPI, and dual UART peripherals for rich connectivity, up to 35 general-purpose I/O, and a 12-bit 1.1 Msps analog-to-digital converter. The 70 MIPS core executes from zero-wait-state Flash, and the device supports multiple switch-mode clock sources and PLL options for deterministic timing.
Architecturally, the dsPIC33EP core implements an enhanced Harvard pipeline with 16-bit data path, 40-bit wide accumulators, and X and Y data memories that allow concurrent fetch of two operands for DSP instructions. Peripheral Pin Select (PPS) lets developers remap digital functions to available pins, easing PCB routing in compact QFN-28 layouts.
Typical applications include motor control systems, digital power supplies, USB-connected industrial sensors, and real-time monitoring nodes where DSP math and USB communication are required on one chip.
A key design consideration: the internal core regulator requires a low-ESR VCAP capacitor on the VCAP pin for stable 1.8V core generation; omitting or misplacing it causes intermittent brownouts.

主な用途
DSPIC33EP128MU202T-I/MM の用途: 6 件s: USB-Connected Industrial Sensors, Digital Power Supplies, Motor Control Systems, Portable Instruments and Handheld Test Devices, Audio Signal Processing Nodes, IoT Gateways and Real-Time Monitoring Nodes.
USB-Connected Industrial Sensors
The DSPIC33EP128MU202T-I/MM fits USB-connected industrial sensor nodes because it is one of the few dsPIC33E parts that integrates a USB 2.0 Full-Speed device controller with a 70 MIPS DSP core on the same die. A sensor node can sample an analog input with the 12-bit 1.1 Msps ADC, apply digital filtering or FFT processing using the DSP multiply-accumulate engine, and stream results over USB to a host PC without any external USB interface chip. The dual SPI and I2C interfaces connect additional digital sensors simultaneously. Compared with adding a discrete USB-UART bridge, the integrated USB saves board area in compact QFN-28 designs and enables firmware-updatable devices via a USB bootloader.
おすすめ
Digital Power Supplies
Digital power supply controllers benefit from the DSPIC33EP128MU202T-I/MM's 70 MIPS execution rate, which allows control-loop update periods in the microsecond range with single-cycle MAC instructions for PI/PID compensation. The 12-bit ADC can sample output voltage and current with 1.1 Msps capability, and PWM peripherals generate switching signals for buck, boost, or LLC stages. The DSP core processes the compensation loop deterministically from zero-wait-state Flash. Typical deployment is a 100-500 W auxiliary or telecom power stage where firmware-defined control thresholds, soft-start curves, and fault responses outperform fixed analog control, while USB enables field configuration of setpoints by a host controller.
おすすめ
Motor Control Systems
The dsPIC33E family is positioned by Microchip for high-performance, precision motor control, and the DSPIC33EP128MU202T-I/MM implements field-oriented control (FOC) for BLDC and permanent-magnet synchronous motors using its 70 MIPS DSP core and hardware MAC unit. Current and position feedback arrives through the 12-bit ADC and quadrature encoder inputs, while PWM peripherals drive a three-phase inverter. For designs needing dedicated motor-control PWM hardware, the pin-compatible DSPIC33EP128MC202 is the stronger choice; the MU202 fits USB-connected drives where commissioning and telemetry run over USB. Typical ratings span 24V to 48V industrial servo and actuator platforms.
おすすめ
Portable Instruments and Handheld Test Devices
Battery-powered instrumentation benefits from the DSPIC33EP128MU202T-I/MM's combination of low-power run modes, a 3.0V-3.6V single-rail supply, and USB device charging/data path in a 6x6 mm QFN-28 footprint. Signal capture uses the 12-bit 1.1 Msps ADC with the DSP engine performing windowing, filtering, or spectrum analysis locally; results are displayed on SPI or parallel-connected LCDs and uploaded via USB. Compared with an MCU-plus-external-DSP two-chip solution, the single-die integration reduces BOM count and sleep-current leakage paths, directly extending battery life in handheld multimeters, environmental meters, and portable diagnostic tools operating over -40C to +85C.
おすすめ
Audio Signal Processing Nodes
The DSP multiply-accumulate architecture of the DSPIC33EP128MU202T-I/MM suits embedded audio processing: 16-bit sample streams from a codec over I2S-compatible SPI or DCI interfaces can be filtered, mixed, or level-controlled with single-cycle MAC instructions at 70 MIPS, leaving headroom for a control interface on the second UART or USB. USB Full-Speed device support allows the same node to appear as a USB audio or HID device to a PC host. The 128 KB Flash accommodates substantial filter coefficient tables and multiple presets. While a dedicated audio DSP achieves higher channel counts, this single-chip DSC is economical for one- or two-channel industrial audio intercoms and alarm processors.
おすすめ
IoT Gateways and Real-Time Monitoring Nodes
The DSPIC33EP128MU202T-I/MM serves as the real-time acquisition element in IoT gateways: dual SPI and dual I2C buses aggregate multiple sensor ICs, the 12-bit ADC handles direct analog channels, and the USB device port provides a commissioning or firmware-update path to a laptop or host gateway. The 70 MIPS core pre-processes vibration or power-quality data (RMS, FFT) locally, transmitting summaries instead of raw streams to the cloud - reducing radio duty cycle and energy use. Peripheral Pin Select simplifies pin budgeting in the 28-pin QFN when several buses are active simultaneously, and the -40C to +85C industrial rating covers unconditioned edge deployments.

設計ノート
The dsPIC33EP core voltage is generated by an internal regulator; a low-ESR ceramic capacitor (on the order of 10 uF per Microchip family datasheet guidance) must be connected at the VCAP pin with a short, direct trace to VSS. Estimated guidance: keep VCAP trace inductance low because regulator instability here manifests as random resets under load transients, not clean brownouts. Do not drive any external load from VCAP. Supply the VDD pins from a 3.0V-3.6V rail; a 3.3V LDO with at least 100 mA headroom is typical for this device plus its I/O budget.
In the 6x6 mm QFN-28, place 0.1 uF decoupling capacitors within 2 mm of each VDD pin pair, and treat AVDD separately: an RC filter (e.g., 10 ohm + 1 uF, estimated values per common Microchip analog layouts) from VDD to AVDD measurably improves 12-bit ADC noise performance. The exposed die paddle should be soldered to a grounded array of vias for thermal and signal-integrity reasons. Keep the PGEC/PGED programming pads on accessible test points since USB cannot serve as the initial programming path.
Peripheral Pin Select (PPS) must be explicitly unlocked and configured before most digital peripherals route to pins - firmware that assumes fixed pin mapping (as on older PIC24) will appear 'dead'. MCLR must be pulled up (approximately 10 kohm, estimate) and not grounded during USB enumeration. The 'T' suffix denotes tape-and-reel packaging, not a die revision; ensure the ordering code matches temperature grade (-I = -40C to +85C). Confirm configuration bit settings for oscillator PLL before relying on the 70 MIPS maximum rating.
