MPN: PIC32MK1024GPK064-I/MR ✓ Hoạt độngPIC32MK1024GPK064-I/MR Tóm tắt
A 32-bit microcontroller (MCU) is a programmable processor that integrates a CPU core, Flash program memory, SRAM data memory, and a rich set of peripherals (ADC, PWM, communication interfaces, timers) on a single silicon die. Within the broader system hierarchy, an MCU sits below an MPU (microprocessor) and above DSPs and ASSPs for embedded control; in the PIC32MK family the core is augmented with a microAptiv pipeline, hardware multiply/divide, optional FPU, and a DSP extension that allows C-code motor-control loops to execute at deterministic latency.
Key features include 120MHz CPU clock, 1MB ECC Flash with live update, 256KB SRAM, USB Full-Speed (Host/Device/OTG), CAN-FD, four 12-bit ADCs with up to 42 analog inputs and 2MSPS aggregate sampling rate, multiple 16-bit PWM channels with 100ps resolution for high-resolution motor control, and Microchip's MPLAB Harmony ecosystem support. MicroMIPS mode delivers up to 40% smaller code size for the same functionality.
Architecturally, the dual-panel Flash allows live-update firmware (running from one panel while programming the other), and the four 64-bit accumulators enable single-cycle MAC operations on 16-bit fixed-point data. This combination makes the device attractive for FOC (field-oriented control) of PMSM/BLDC motors, multi-channel power conversion, and DSP-augmented IIoT edge nodes.
Typical applications include BLDC/PMSM motor drives (FOC with HRPWM), industrial sensor hubs, multi-channel data acquisition systems, IIoT edge controllers, and USB/CAN-FD connected industrial nodes. The 64-QFN MR package provides a compact thermal-efficient footprint suited to space-constrained industrial PCBs.
When designing with this device, prioritize MPLAB X IDE + XC32 compiler + Harmony framework, ensure VDD/AVDD decoupling per the datasheet reference circuit, and confirm the 9x9 mm QFN land pattern supports your PCB process window (the exposed pad must be soldered to a continuous ground plane for thermal dissipation).

Ứng dụng tiêu biểu
PIC32MK1024GPK064-I/MR phù hợp cho 7 Áp dụngs: BLDC / PMSM Motor Drive (FOC), Industrial IoT Edge Controller, Multi-Channel Data Acquisition System, Solar / Power Conversion MPPT Controller, Industrial Sensor Hub / Transmitter, USB-Connected Industrial Diagnostics Tool, Building Automation / HVAC Controller.
BLDC / PMSM Motor Drive (FOC)
The PIC32MK1024GPK064-I/MR is purpose-built for field-oriented control of brushless DC and permanent-magnet synchronous motors. Its four integrated 12-bit ADCs enable simultaneous sampling of the three phase currents and DC-bus voltage, which is essential for the Clarke/Park transform feedback loop in FOC. The 120MHz microAptiv + DSP engine executes the FOC math at sub-microsecond latency; the integrated 16-bit high-resolution PWM (100ps edge placement) keeps torque ripple low even at low RPM. The 1MB Flash holds field-weakening and MTPA tables for sensorless control, while ECC protects against bit-flip corruption in industrial environments. A typical 3-phase FOC implementation fits comfortably in <40KB of Flash, leaving headroom for communication stacks (CAN-FD for multi-node drives, USB for commissioning).
Được đề xuất
Industrial IoT Edge Controller
The PIC32MK1024GPK064-I/MR fits Industrial IoT edge nodes that aggregate multiple sensor inputs and forward pre-processed data to the cloud via USB or CAN-FD. Four 12-bit ADCs digitize up to 42 analog sensor channels at 2MSPS aggregate, while USB Full-Speed (Host/Device/OTG) provides local console and modem connectivity. The 256KB SRAM supports TCP/IP stacks (e.g., MPLAB Harmony Net) without external memory. The DSP MAC accelerates on-device analytics (FFT, RMS) before transmission, reducing WAN bandwidth. ECC Flash keeps field-deployed firmware integrity intact despite industrial EMI. Industrial -40C to +85C operation covers most factory floor environments.

Multi-Channel Data Acquisition System
With 42 analog inputs across four 12-bit ADCs running up to 2MSPS aggregate, the PIC32MK1024GPK064-I/MR serves as a compact multi-channel data acquisition front-end. USB Full-Speed streams digitized samples to a host PC at >1MSPS sustained, while CAN-FD delivers deterministic real-time data to industrial controllers. The DSP MAC performs on-chip filtering (FIR, decimation) to reduce host-side processing. ECC Flash and 256KB SRAM buffer transient bursts without loss. This combination replaces discrete ADC + FPGA + MCU three-chip designs with a single MCU, reducing BOM cost and PCB area in test-and-measurement and process-control equipment.

Solar / Power Conversion MPPT Controller
Maximum Power Point Tracking (MPPT) solar charge controllers and bidirectional DC-DC converters benefit from the PIC32MK1024GPK064-I/MR's 100ps-resolution PWM, four simultaneous ADCs (PV voltage, PV current, battery voltage, battery current), and DSP FPU math for perturb-and-observe or incremental-conductance MPPT algorithms. The 1MB Flash holds multiple MPPT profiles for varied PV module configurations. ECC protection preserves firmware reliability in outdoor enclosures. The 64-QFN package fits compact solar-harvesting PCBs where power density per cubic centimeter matters. USB enables on-site firmware updates during commissioning and field service.

Industrial Sensor Hub / Transmitter
The PIC32MK1024GPK064-I/MR integrates multi-sensor processing in a compact 64-QFN footprint: 4x 12-bit ADCs digitize temperature, pressure, flow, and level sensors; the DSP MAC runs compensation algorithms (linearization, RTD/Pt100 polynomial fit, thermistor beta compensation); USB and CAN-FD communicate with PLCs and SCADA hosts. The 1MB Flash supports multiple sensor calibration profiles and on-device HART or IO-Link protocol stacks. Industrial -40C to +85C operation and ECC Flash integrity are critical for process-industry sensor hubs that must operate maintenance-free for years in hazardous-area enclosures.

USB-Connected Industrial Diagnostics Tool
Handheld industrial diagnostic and commissioning tools benefit from the PIC32MK1024GPK064-I/MR's USB Full-Speed Host/Device/OTG plus four ADCs and high-resolution PWM. The device can drive a small HMI display (USB graphics), excite a sensor under test with calibrated PWM, sample its response with the ADCs, and stream the result over USB to a host laptop. The 1MB Flash holds calibration certificates and unit-specific data. ECC Flash keeps the unit's calibration constants intact over years of field service. The 64-QFN 9x9 mm package fits compact handheld enclosures with adequate thermal headroom.
Được đề xuất
Building Automation / HVAC Controller
The PIC32MK1024GPK064-I/MR supports HVAC variable-air-volume (VAV) controllers and building-automation nodes. Four 12-bit converters read temperature, humidity, CO2, and air-flow sensors simultaneously; the DSP engine runs filter and trend algorithms; USB and CAN-FD integrate with BACnet/MS-TP and Modbus building networks. ECC protection guards against the inrush noise of HVAC relay switching. The 1MB Flash supports multiple building-floor profiles and time-of-day scheduling. Industrial temperature grade and the compact 64-QFN package allow installation inside ceiling-mounted VAV boxes where space is constrained.

Ghi chú thiết kế
Decouple all VDD/VSS pairs of the PIC32MK1024GPK064-I/MR with 100nF X7R ceramic capacitors placed within 3 mm of each supply pin; place a bulk 10uF X5R ceramic near the IC and a 10-22uF tantalum or polymer aluminum capacitor on the same net. Use separate analog and digital ground planes tied at a single-point near the IC's exposed pad. AVDD must be tied to VDD or driven by a low-noise LDO (e.g., MCP1700) when ADC performance below 1 LSB noise is required; do not share AVDD with switching-node voltages.
The 64-QFN 9x9 mm package dissipates up to ~1.0 W with theta-JA around 28 C/W per the family datasheet thermal data. Solder the exposed thermal pad (EP, pin 65) to a continuous top-layer ground copper pour of at least 1 square inch with multiple thermal vias to inner ground planes. Without the EP soldered, junction temperature can rise above the +85C industrial limit at high CPU activity. The Microchip family datasheet provides PCB land-pattern and via-array guidance for the 64-QFN (MR) footprint.
Route all analog ADC traces as differential pairs with a continuous ground reference underneath, and keep them >5 mm away from switching-node traces (PWM outputs, gate-driver lines, inductor switching). Use guard rings around sensitive analog inputs. Place the 4x ADCs' reference bypass capacitor (4.7uF X7R + 100nF NP0) within 5 mm of the AVREF pin. For USB Full-Speed, the D+/D- traces must be 90-ohm differential with length-matched within 150 mil; place the 27-ohm series resistors within 2 mm of the IC.
Do not connect any VDD pin to a different rail than VDD (some pinout maps label VDD/VDDIO separately in microA/B families, but on PIC32MK all VDD pins share the 2.3-3.6 V core rail). Ensure all unused I/O are configured as outputs driven low (not left floating) to reduce power consumption and ADC noise coupling. When programming via ICSP, the PGECx/PGEDx pair must be dedicated and not shared with JTAG or peripherals during programming.
Spread-spectrum clock configuration and peripheral clock gating reduce EMI in industrial environments. Configure PWM outputs with complementary mode and dead-time insertion per motor-control requirements to prevent shoot-through in the external gate driver. Add common-mode chokes on USB D+/D- and CAN-FD bus lines for CE/EN 55011 Class A EMI compliance. The on-chip FCR (Frequency Change Register) PLL allows CPU operation from a low-frequency crystal to minimize radiated emissions.
