PIC32MK1024MCM064T-E/MR 概述
A 32-bit microcontroller (MCU) is a programmable system-on-chip integrating a CPU core, non-volatile program memory (Flash), volatile working memory (SRAM), and a rich set of analog and digital peripherals on a single die. The PIC32MK family uses the MIPS32 microAptiv core, which fits into the broader taxonomy: microcontroller -> 32-bit MCU -> MIPS-based MCU -> PIC32MK series. These MCUs sit between simple 8/16-bit controllers and high-end application processors, optimized for deterministic real-time control with DSP extensions and motor-control-oriented peripherals.
Key differentiating features include a 120 MHz operating frequency with DSP instructions, hardware multiply/divide and MAC unit, dual 12-bit ADC modules supporting up to 42 analog inputs at 3.75 MSPS, four 16-bit Compare/PWM outputs optimized for motor-drive switching, dual CAN-FD controllers for industrial networking, USB Full-Speed OTG, and 1 MB ECC Flash plus 256 KB SRAM. The 64-QFN (9x9 mm) package exposes a thermal pad enabling dissipation of roughly 1.5 W without external heatsinking for typical motor-control duty cycles.
Architecturally, the device pairs a microAptiv core with Microchip's peripheral set including dedicated PWM, quadrature encoder interface, and high-resolution 12-bit ADC capable of simultaneous sampling for field-oriented control. The 1 MB ECC Flash enhances reliability for industrial and automotive-style applications by detecting and correcting single-bit errors during runtime, reducing field-return risk.
Typical applications include BLDC and PMSM motor drives (field-oriented control), industrial PLC modules, multi-channel data acquisition front-ends, IIoT edge nodes with CAN-FD connectivity, and consumer appliance motor control. The wide peripheral mix supports both power conversion and real-time communication on a single chip, reducing BOM and PCB area.
Designers should allocate 100 nF + 4.7 uF decoupling near the VDDCORE and VDDIO pins, route the analog AVSS/AVDD pair with a low-impedance ground plane, and follow Microchip AN2685 for QFN PCB land pattern and thermal via design. The E temperature grade (-40C to +125C) requires derating of junction temperature under sustained high-core-activity workloads.

典型应用
PIC32MK1024MCM064T-E/MR 适用于 7 应用s: BLDC and PMSM Motor Control, Industrial PLC and Field I/O Modules, Multi-Channel Data Acquisition, Industrial IoT Edge Nodes, Consumer Appliance Motor Drives, Power Conversion and PFC Front-Ends, Robotics and Servo Drives.
BLDC and PMSM Motor Control
The PIC32MK1024MCM064T-E/MR is purpose-built for BLDC and PMSM field-oriented control. Its 120 MHz MIPS32 microAptiv core with DSP ASE executes FOC algorithms in under 10 us loop time, while four 16-bit PWM outputs with hardware dead-band generation drive half-bridges at up to 100 kHz. Dual 12-bit ADCs sample phase currents simultaneously at 3.75 MSPS, eliminating the delay between current measurements that causes torque ripple. The 1 MB ECC Flash supports multiple motor profiles and application firmware with field-upgrade capability.
推荐
Industrial PLC and Field I/O Modules
With dual CAN-FD controllers and USB Full-Speed OTG, the PIC32MK1024MCM064T-E/MR serves as the main MCU on industrial PLC digital and analog I/O modules. CAN-FD provides high-bandwidth deterministic communication between modules at 5 Mbit/s, while the 1 MB Flash allows the module firmware to host IEC 61131-3 runtime, communication stacks, and diagnostic logs. The 256 KB SRAM accommodates protocol buffers and dual-port communication state. The -40C to +125C E temperature grade supports cabinet-free deployment.
推荐
Multi-Channel Data Acquisition
The dual 12-bit ADC modules in the PIC32MK1024MCM064T-E/MR provide up to 42 analog input channels, well-suited to multi-channel data-acquisition front-ends for vibration, strain gauge, and thermocouple arrays. Simultaneous conversion across the two modules preserves phase relationships between channels, critical for power-quality analyzers and condition-monitoring systems. The 1 MB Flash hosts calibration tables and DSP filter coefficients, while the 256 KB SRAM buffers sample streams before post-processing or upload over USB or CAN-FD.
推荐
Industrial IoT Edge Nodes
The PIC32MK1024MCM064T-E/MR is well-suited to IIoT edge nodes that aggregate sensor data and forward it over CAN-FD or USB. The 120 MHz core runs TCP/IP stacks and local analytics, while 1 MB ECC Flash stores firmware, configuration, and cryptographic keys. The dual CAN-FD ports act as bridges between legacy CAN networks and modern Ethernet/USB uplinks. ECC Flash protects against bit flips in electrically harsh factory environments, reducing field-return risk for IIoT deployments.
推荐
Consumer Appliance Motor Drives
Washing machines, dishwashers, and HVAC blowers increasingly use variable-speed BLDC motors for efficiency, all of which can be driven by the PIC32MK1024MCM064T-E/MR. The four dedicated 16-bit PWM channels and quadrature encoder interface handle direct-drive drum or compressor motors. The 1 MB ECC Flash provides space for application code plus multiple motor calibration profiles. The QFN-64 9x9 mm package keeps BOM cost low while supporting high switching frequencies for silent drive operation.
推荐
Power Conversion and PFC Front-Ends
The PIC32MK1024MCM064T-E/MR's high-resolution PWM and fast 12-bit ADC make it suitable for digital power factor correction (PFC) and LLC resonant converter control. The 120 MHz core executes digital average-current-mode PFC loops in under 5 us, while four PWM outputs drive boost and auxiliary FETs. CAN-FD connectivity enables telemetry reporting to a system controller for solar inverters and UPS front-ends. The 256 KB SRAM holds oscilloscope-style debug buffers for firmware development.
推荐
Robotics and Servo Drives
Multi-axis robotic arms and CNC servo drives require deterministic motor control and high-speed communication. The PIC32MK1024MCM064T-E/MR drives a single BLDC servo axis, with four 16-bit PWM channels for H-bridge control and quadrature encoder interface for position feedback. Multiple PIC32MK1024MCM064T-E/MR MCUs can be coordinated over CAN-FD for multi-axis systems. The 1 MB Flash allows field-upgradeable firmware and application-specific motion profiles without external memory.

设计说明
The 64-QFN package has an exposed thermal pad (EP) that must be soldered to a ground-plane thermal land with at least a 6x6 via array (0.3 mm vias, 1.2 mm pitch) for adequate heat dissipation. Estimated: at 120 MHz full-speed operation with all peripherals active, the MCU draws ~80 mA from 3.3V, dissipating ~0.26 W. The exposed pad keeps junction-to-ambient thermal resistance around 25 C/W, well within the 125C max junction for industrial applications.
Place a 100 nF X7R 0402 ceramic decoupling capacitor within 2 mm of each VDD pin and a single 4.7 uF X5R bulk capacitor at the package entry. Connect analog AVDD1/AVDD2 through a ferrite bead to VDD to isolate ADC reference noise. Power-on reset is automatic at VDD > 1.8V; ensure VDD rise time is < 50 ms to avoid POR timing issues. The MCU operates from 2.5V or 3.3V; do not exceed 3.6V absolute maximum on any pin.
Route the analog ANx inputs as guard-traced differential pairs to the ADC pins, keeping analog traces away from PWM switching nets by at least 3 mm. The USB D+/D- traces require 90 ohm differential impedance and should be length-matched within 2 mm; place a common-mode choke within 5 mm of the connector. The crystal oscillator traces (OSC1/OSC2) should be short, surrounded by a ground ring, and isolated from switching signals.
Do not leave the OSC1/OSC2 pins floating when using an external clock - configure the OSCCON register correctly for the chosen source. The ADC inputs can be damaged by voltages above AVDD + 0.3V; add external clamp diodes if the input can exceed this. The CAN-FD bus requires 120 ohm termination at both ends of the bus; missing termination causes bit errors at high data rates. Finally, configure unused I/O pins as outputs driven low to minimize supply current.
