PIC32MK0512MCF064 - 120MHz 32-Bit MCU with FPU | Microchip
MPN: PIC32MK0512MCF064 ✓ פעילPIC32MK0512MCF064 סקירה
A 32-bit MCU combines a processor core, memory, and programmable peripherals on a single integrated circuit. With a 32-bit data path, it delivers greater performance and memory addressing than 8-bit or 16-bit MCUs. The PIC32MK family sits in the microcontroller hierarchy as a general-purpose and motor-control application MCU, positioned for industrial control and IIoT systems.
Key features include seven 12-bit ADCs each running at up to 3.75 MSPS, multiple CAN 2.0B controllers, USB FS device support, four I2C and six I2S interfaces, PWM modules, and quadrature encoder interfaces (QEI). The integrated FPU accelerates single-precision floating-point math while DSP instructions speed filtering and control loops. Operating voltage spans 2.3V to 3.6V with industrial temperature grades of -40C to +85C (I suffix) or -40C to +125C (E suffix).
The MIPS32 microAptiv core uses a 5-stage pipeline delivering 1.5 DMIPS/MHz, so at 120 MHz the device achieves roughly 180 DMIPS. A DMA controller offloads data movement between ADCs, communication peripherals, and SRAM, keeping the CPU free for control algorithms. In-Circuit Serial Programming (ICSP) via PGECx/PGEDx pin pairs simplifies field programming, and SEGGER debug tools are supported.
Typical applications include field-oriented control (FOC) of brushless DC motors, multi-channel CAN gateways, and IIoT edge nodes requiring real-time sensing and control. The high-channel-count ADC plus PWM makes it well suited to closed-loop multi-phase motor drives.
Design tip: decouple the 3.3V supply carefully at every VDD pin and pair PGECx/PGEDx pins correctly for programming. Pricing as of 2026-08-29 starts around $11.48 at LCSC.

יישומים טיפוסיים
PIC32MK0512MCF064 מתאים עבור 6 יישוםs: BLDC/PMSM Motor Control (FOC), Multi-Channel CAN Gateway, IIoT Edge Node, Industrial Control and Automation, Digital Audio / Multi-Channel I2S Systems, Power Conversion / Digital Power Supplies.
BLDC/PMSM Motor Control (FOC)
The PIC32MK0512MCF064 fits sensorless and sensored FOC motor drives because its seven 12-bit ADCs sample at up to 3.75 MSPS, enabling simultaneous multi-phase current sensing without external sample-and-hold circuitry. The FPU and DSP instructions execute Clarke/Park transforms and PI loops at 20 kHz+ PWM rates, while dedicated PWM and QEI peripherals handle commutation. Place it between gate drivers and current shunt amplifiers; the DMA moves ADC results to SRAM with no CPU intervention, cutting loop latency. Its 120 MHz core leaves ample headroom for protocol handling in the same chip.
מומלץ
Multi-Channel CAN Gateway
Multi-channel CAN 2.0B controllers plus a 120 MHz MIPS32 core with DMA make this MCU ideal for routing frames between CAN buses in vehicles and industrial machines. Message filtering and routing occur in hardware, keeping CPU load low even at high bus utilization, and the 512 KB Flash holds large routing tables and diagnostic stacks (UDS/OBD). Pair each CAN controller with a transceiver such as the TCAN1042GVDRQ1; the 3.3V I/O simplifies level-compatible integration. The extended temperature E-grade option covers under-hood environments up to +125C.
מומלץ
IIoT Edge Node
The PIC32MK0512MCF064 serves as an IIoT edge node combining sensor acquisition and connectivity: seven ADCs read analog sensors at up to 3.75 MSPS while USB FS and multiple UART/SPI/I2C ports link to radios and displays. The 512 KB Flash and 128 KB SRAM host protocol stacks and local analytics, and DSP instructions accelerate FFT-based vibration or power-quality analysis at the edge. Operating from 2.3V to 3.6V suits battery-buffered and industrial 3.3V rails; ICSP enables field firmware updates without removing the board from its enclosure.
מומלץ
Industrial Control and Automation
In PLC I/O modules and industrial controllers, this MCU provides deterministic 120 MHz processing with a rich peripheral set: multiple PWM outputs drive actuators, quadrature encoder interfaces read position feedback, and several CAN/UART channels link to field networks. The seven ADCs enable multi-loop monitoring of currents, voltages, and temperatures in a single device, reducing BOM count versus discrete front ends. With -40C to +85C (I) or +125C (E) grades and 2.3V to 3.6V operation, it tolerates harsh cabinet environments with supply sag.
מומלץ
Digital Audio / Multi-Channel I2S Systems
With six I2S interfaces, the PIC32MK0512MCF064 can aggregate several audio streams simultaneously, making it suitable for automotive audio amplifiers, mixers, and DSP front ends. The 120 MHz core and DSP instructions perform volume, EQ, and mixing operations, while DMA streams I2S data with minimal jitter contribution. The 512 KB Flash stores configuration and DSP coefficient tables. Use it alongside audio codecs or amplifiers such as the TAS6754QDKQRQ1; the multiple I2S ports eliminate external stream-muxing glue logic that smaller MCUs require.
מומלץ
Power Conversion / Digital Power Supplies
Digital power supplies and solar/charger controllers benefit from this MCU's fast simultaneous ADC sampling and flexible PWM outputs. Phase currents and output voltage are sampled at up to 3.75 MSPS per ADC, feeding control loops executed with FPU precision at switching frequencies up to hundreds of kHz. Multiple CAN/UART links support telemetry and PMBus-style host communication, and 512 KB Flash holds compensation tables for wide operating ranges. Combine with a wide-VIN buck such as the TPS54360QDDARQ1 for auxiliary power and gate drivers like the UCC21710-Q1 for isolated stages.

הערות תכנון
Decouple every VDD pin with 100 nF ceramic capacitors placed within 2 mm of the pin, plus a 10 uF bulk capacitor near the 3.3V entry point. The VDDCORE/VCAP pin requires the datasheet-specified low-ESR capacitor for the internal core regulator - omitting it prevents startup. Keep AVDD/AVSS on a separate filtered 3.3V rail with an LC filter (ferrite bead + 1 uF) to preserve 12-bit ADC accuracy when switching loads share the supply.
Use multiple PGECx/PGEDx pairs wisely: route your chosen programming pair (e.g., PGEC2/PGED2) to a standard ICSP header on every production board, avoiding pull-ups >10k on these pins during programming. Keep USB D+/D- as a 90-ohm differential pair, length-matched within 1 mm. Place CAN controller pin routing to transceivers short and direct; series-terminate at 22-33 ohms if traces exceed 5 cm to control reflections.
Do not drive the MCLR pin from push-pull logic during ICSP - use open-drain or a resistor to allow the programmer to apply VPP. Configure unused I/O as outputs driving low or inputs with pull-ups to prevent floating-node EMI. When migrating from the -I/PT to the -E/PT grade, re-verify derating of ADC accuracy at +125C per the datasheet analog tables, not just digital timing.
