PIC32MK1024MCF064-I/MR 概要
A 32-bit microcontroller (MCU) is an integrated circuit that combines a 32-bit processor core, program memory (Flash), data memory (RAM), and a rich set of programmable peripherals on a single die. The PIC32MK family sits within the broader hierarchy of microcontroller -> embedded controller -> semiconductor device, and the microAptiv core provides deterministic interrupt response suited to closed-loop control loops. ECC-protected Flash is increasingly important for industrial safety certifications such as IEC 61508 SIL-2 paths.
Key differentiating features of the PIC32MK1024MCF064-I/MR include six I2S channels (versus four on most PIC32MX parts), four I2C ports, CAN 2.0B, USB Full-Speed, a 12-bit multi-channel ADC, dedicated motor-control PWMs with complementary outputs and dead-time insertion, and 1 MB of Flash that allows substantial field-upgradeable firmware. The 120 MHz core delivers 198 DMIPS and 3.75 CoreMark/MHz class performance for real-time control math.
Architecturally, the device uses the MIPS32 microAptiv M4K-class core with single-cycle MAC, hardware multiply/divide, and tightly-coupled peripherals such as the 12-bit 6.4 Msps ADC and the motor-control PWM (MCPWM) with up to 1.04 ns resolution at 120 MHz. ECC on Flash and parity on RAM support functional-safety designs.
Typical applications include field-oriented control (FOC) of 3-phase PMSM and BLDC motors, industrial PLC I/O modules, IIoT sensor nodes with CAN or USB connectivity, multi-axis servo drivers, and digital power conversion stages.
When designing with this MCU, allocate sufficient PCB copper under the exposed pad for thermal dissipation, since high PWM switching can drive significant core current. Decouple AVDD and VDD separately with 100 nF + 10 uF ceramic capacitors placed within 3 mm of the package pins.

主な用途
PIC32MK1024MCF064-I/MR の用途: 6 件s: Field-Oriented Control (FOC) of PMSM/BLDC Motors, Industrial PLC and Remote I/O Modules, Industrial IoT (IIoT) Sensor Hubs, Digital Power Conversion and PFC Stages, Multi-Axis Servo and Stepper Motor Controllers, Automotive Auxiliary Motor Controllers.
Field-Oriented Control (FOC) of PMSM/BLDC Motors
The PIC32MK1024MCF064-I/MR is purpose-built for 3-phase field-oriented control of PMSM and BLDC motors. Its integrated motor-control PWM provides complementary outputs with programmable dead-time insertion at 1.04 ns resolution at 120 MHz, while the 12-bit multi-channel ADC samples phase currents at up to 6.4 Msps for closed-loop current feedback. The MIPS32 microAptiv core executes Park/Clarke transforms with single-cycle MAC, sustaining FOC loop rates well below 10 us. Microchip's MPLAB Harmony motor-control framework (AN1078, AN1292) provides validated firmware building blocks directly targeting this device, reducing time-to-market for servo drives, drone ESCs, and e-bike traction controllers.
おすすめ
Industrial PLC and Remote I/O Modules
The PIC32MK1024MCF064-I/MR fits industrial PLC digital and analog I/O modules because of its 120 MHz core, 1 MB ECC Flash for boot-loader and field-upgrade image storage, and rich connectivity (4x I2C, 6x I2S, USB FS, CAN 2.0B). ECC-protected Flash supports functional-safety paths to IEC 61508 SIL-2, which is increasingly required for process-control hardware. The 64-QFN exposed-pad package simplifies thermal management in sealed IP67 enclosures. Microchip's MPLAB Harmony 3 includes validated PLC framework middleware that maps digital I/O, Modbus RTU, and CANopen DS301 to this MCU with example projects and driver stacks.
おすすめ
Industrial IoT (IIoT) Sensor Hubs
The PIC32MK1024MCF064-I/MR enables IIoT edge sensor hubs aggregating multi-sensor data over I2C, SPI, and I2S, then forwarding it via CAN or USB. Its 256 KB RAM buffers time-series sensor data before transmission, while the 1 MB Flash stores the TCP/IP or CANopen stack plus over-the-air (OTA) firmware images. The USB Full-Speed port supports both device and embedded-host modes for tethering to gateways or local HMI panels. ECC on Flash reduces the risk of silent bit-flips corrupting firmware during long field deployments, which is critical for predictive-maintenance nodes operating unattended for years.
おすすめ
Digital Power Conversion and PFC Stages
The PIC32MK1024MCF064-I/MR runs digital PFC and full-bridge LLC/LLC resonant converter control loops where its 120 MHz microAptiv core delivers the math throughput for predictive dead-time optimization and adaptive zero-voltage switching (ZVS). The 12-bit ADC samples inductor current and output voltage at high rates, while the motor-control PWM outputs are repurposed as high-resolution complementary PWMs for the power stage. Microchip's AN1330 reference design targets this MCU directly for 1-3 kW telecom rectifiers and server PSUs, where 1 MB Flash and 256 KB RAM are sufficient for control loops plus telemetry stack.
おすすめ
Multi-Axis Servo and Stepper Motor Controllers
The PIC32MK1024MCF064-I/MR coordinates multiple stepper or servo axes when its dedicated motor-control PWMs are time-multiplexed to drive dual-axis stepper drivers or up to three BLDC axes in current-mode. The 256 KB RAM holds 4 PID loops plus trajectory planner state, while 1 MB Flash stores the kinematics library and CANopen DS402 (CiA 402) drive profile stacks. The industrial -40C to +85C temperature range supports factory-floor cabinet mounting. Engineers migrating from PIC32MX can reuse most peripheral drivers due to register-level compatibility within the PIC32 family.
おすすめ
Automotive Auxiliary Motor Controllers
The PIC32MK1024MCF064-I/MR drives auxiliary automotive loads such as HVAC blower motors, electric water pumps, and electric oil pumps when paired with an external gate driver. The industrial-grade temperature rating supports under-hood non-safety applications; for safety-relevant drivetrain or ADAS loads, Microchip sells AEC-Q100-qualified variants in the same PIC32MK family (ordering code suffix -Q1). CAN 2.0B integration simplifies body-network integration with the vehicle CAN bus, and the 1 MB ECC Flash supports AUTOSAR-style bootloader plus secure firmware update over CAN.

設計ノート
The 64-QFN 9x9 mm package relies on the exposed pad (EP) for primary thermal and ground return. The Microchip datasheet specifies theta-JA of approximately 31 C/W on a JEDEC 4-layer test board; in a real motor-control board with only 2 layers or limited inner copper, expect theta-JA of 40-50 C/W. Place at least 9 thermal vias (0.3 mm drill, 0.6 mm pad) under the EP on a 1.0 mm grid to drop junction-to-ambient resistance below 25 C/W. The MCU draws up to ~70 mA active at 120 MHz with all peripherals on, so worst-case junction rise is roughly 1.7 C above ambient on a properly designed board.
Decouple AVDD and VDD with separate 100 nF + 10 uF ceramic capacitor pairs within 3 mm of the package pins. The PIC32MK1024MCF064 datasheet shows AVDD sensitivity to high-current PWM switching; route PWM traces away from AVDD and place a ferrite bead between digital VDD and analog AVDD supplies if they share a regulator. Use a low-noise LDO (such as Microchip MCP1755) for AVDD if the upstream rail is a switching regulator, since the 12-bit ADC ENOB drops when supply noise exceeds 1 mVrms.
Route the motor-control PWM traces (PWM1H/L through PWM3H/L) as differential pairs with 8-10 mil trace width and 8 mil spacing, keeping them under 25 mm total length to limit ringing. The 1.04 ns PWM resolution at 120 MHz is meaningless if the gate-driver input capacitance causes 5-10 ns of edge ringing. Place the MCP8024 or equivalent gate driver within 15 mm of the MCU PWM outputs and use a ground guard trace between PWM outputs and analog ADC inputs to keep dV/dt noise out of current-sense amplifiers.
Estimated: do not program the configuration bits to source the system clock from the internal FRC at default reset without verifying the PLL multiplier and FRC postscaler settings - many FOC field returns trace to a misconfigured PLL that drops the core to 30 MHz instead of 120 MHz. Use the MPLAB Harmony Clock Manager or the MCC graphical configurator instead of manually setting OSCCON/SPLLCON registers. Also, do not leave unused GPIO pins floating; configure them as outputs low or inputs with the internal weak pull-up enabled to avoid parasitic ADC channel crosstalk.
Place the 12-bit ADC reference decoupling (100 nF + 10 uF) directly at the VREF+/VREF- pins with the shortest possible trace to AVSS - the reference pin is the dominant noise injection path on PIC32MK ADC measurements. Keep digital switching traces (PWM, SPI clock) at least 5 mm away from the VREF+ trace, or guard it with ground on both sides. For shunt-resistor current sensing, use a 4-wire Kelvin connection from the shunt to the dedicated analog pins (AN0/AN1 typically) to avoid ground-loop errors of several ADC counts.
コンプライアンス情報
Standard -I/MR variant is industrial-grade (-40C to +85C) and not AEC-Q100 qualified. AEC-Q100 Grade 1 qualified variants are available in the PIC32MK family with -Q1 suffix; verify exact ordering code with Microchip for automotive designs.
