PIC32MK0512GPG048-I/7MX 概要
A 32-bit microcontroller (MCU) is a single-chip computer that integrates a 32-bit CPU core, Flash program memory, SRAM data memory, and a rich peripheral set on one die. The PIC32MK family is positioned in Microchip's PIC32 lineup as a high-performance general-purpose and motor-control platform, sitting architecturally above the PIC32MX and PIC32MM lines. Within the PIC32MK taxonomy, the GPG family adds CAN FD and ECC, and the 0512GPG048 sub-variant specifically targets 512 KB Flash / 64 KB RAM / 48-pin compact designs. Compared with an 8-bit MCU such as PIC16, a 32-bit MIPS core offers 4-byte instruction throughput, hardware FPU single-precision floating-point, and DSP-oriented MAC units.
Key features include a hardware Floating Point Unit (FPU) for IEEE-754 single-precision math, DSP extensions for signal processing, 5V-tolerant I/O with up to 22 mA source/sink, selectable internal pull-ups, pull-downs, and open-drain modes, five programmable edge/level-triggered interrupt pins, and external interrupts on all GPIO. The 48-VQFN package supports surface-mount manufacturing with a small 6x6 mm footprint and an exposed pad for thermal dissipation.
The PIC32MK0512GPG048-I/7MX combines a MIPS32 microAptiv core with deterministic interrupt response, hardware FPU, and DSP MACs. The ECC-protected Flash improves reliability in industrial environments by detecting and correcting single-bit errors in program memory, reducing the risk of firmware corruption in long-lifecycle deployments. The integrated CAN FD peripheral enables higher-bandwidth automotive and industrial networking than classic CAN 2.0B.
Typical applications include industrial motor control (BLDC/PMSM/servo drives), industrial automation and PLC I/O modules, Industrial Internet of Things (IIoT) edge nodes, multi-channel ADC-based sensor conditioning, and automotive body/comfort modules requiring CAN FD. The combination of FPU and DSP MACs accelerates field-oriented control (FOC) loops commonly used in motor drives.
When designing with this part, ensure the exposed thermal pad is properly soldered to a sufficient copper pour for heat dissipation. Decouple VDD/VSS pairs with 100 nF ceramic capacitors placed as close as possible to the IC pins. For CAN FD networks, terminate the bus with 120 ohm resistors at each end and verify the CAN transceiver slew rate is configured for the chosen bitrate.

主な用途
PIC32MK0512GPG048-I/7MX の用途: 6 件s: BLDC/PMSM Motor Control (FOC), Industrial CAN FD Node, IIoT Edge Gateway / Sensor Node, Multi-Channel ADC Data Acquisition, Automotive Body/Comfort Module, Programmable Logic Controller (PLC) I/O Module.
BLDC/PMSM Motor Control (FOC)
The PIC32MK0512GPG048-I/7MX fits BLDC and PMSM motor control applications because of its 120 MHz MIPS core with hardware IEEE 754 single-precision FPU and DSP MAC extensions, which accelerate field-oriented control (FOC) loops by 30-50% versus software-emulated floating-point. The 512 KB ECC Flash holds motor control firmware plus fault handling state machines, and the 64 KB SRAM accommodates Park/Clarke transform buffers and current-loop sample arrays. Its 5V-tolerant 22 mA GPIO directly drives gate-driver optocouplers and PWM signals up to 120 MHz peripheral bus speeds. The 48-VQFN footprint is compact enough for integrated motor-drive PCBs under 50x50 mm, where the exposed pad dissipates 1-2 W from the MCU itself. This makes it ideal for compact FOC servo drives, drone ESCs, and appliance motor controllers.
おすすめ
Industrial CAN FD Node
The PIC32MK0512GPG048-I/7MX is well suited for industrial CAN FD nodes thanks to its integrated CAN FD peripheral supporting bitrates up to 5 Mbit/s in the data phase and 64-byte payloads versus 8-byte classic CAN. The 512 KB Flash stores CANopen or J1939 protocol stacks, and the 64 KB SRAM buffers message queues for sub-millisecond deterministic response. The 5V-tolerant GPIO interfaces directly with industrial 24V sensor bridges via external transceivers like the MCP2558FD. ECC Flash prevents single-bit corruption in long-lifecycle factory deployments, critical for Industry 4.0 predictive-maintenance nodes. This makes the part ideal for programmable logic controllers (PLCs), distributed I/O blocks, and industrial sensor hubs.
おすすめ
IIoT Edge Gateway / Sensor Node
The PIC32MK0512GPG048-I/7MX fits Industrial IoT (IIoT) edge node applications because of its combination of 120 MHz core with FPU, 512 KB ECC Flash, and 64 KB SRAM. These resources support on-device TCP/IP stacks, TLS handshake buffers, and sensor-fusion algorithms without an external MPU. The DSP extensions accelerate FFT and digital filtering on vibration or acoustic sensors, reducing cloud bandwidth by 50-70%. The 48-VQFN package enables compact edge-node PCBs that fit inside sensor housings, and the -40C to +85C industrial temperature range covers factory-floor deployments. This makes it ideal for predictive-maintenance vibration nodes, IIoT gateways aggregating Modbus TCP and CAN FD, and remote telemetry units.
おすすめ
Multi-Channel ADC Data Acquisition
The PIC32MK0512GPG048-I/7MX suits multi-channel ADC data acquisition because of its high-speed 12-bit ADC and DSP extensions for real-time signal conditioning. With 512 KB of flash and 64 KB of SRAM, the MCU can buffer ADC samples and run DSP-based filtering on vibration, acoustic, or current measurements. The 5V-tolerant GPIO directly interfaces with industrial 4-20 mA or 0-10 V sensor signals via external signal conditioning, and the 120 MHz core sustains deterministic sampling rates up to hundreds of kHz per channel. ECC Flash improves long-term data integrity for logging applications.
おすすめ
Automotive Body/Comfort Module
The PIC32MK0512GPG048-I/7MX fits automotive body and comfort modules thanks to its CAN FD support, 5V-tolerant GPIO (matching 5V automotive rails), and 22 mA source/sink capability to drive LED drivers and relay coils directly. The 512 KB Flash holds CAN FD body-domain stacks (door modules, seat controllers, lighting), while the 64 KB SRAM supports multi-channel LIN-to-CAN gateway tasks. ECC Flash prevents firmware corruption in long-lifecycle vehicle deployments. For under-hood or harsh-environment designs, the -E/7MX extended-temperature variant is preferred over the -I industrial variant. This makes the part ideal for body control modules, HVAC panels, and lighting controllers.
おすすめ
Programmable Logic Controller (PLC) I/O Module
The PIC32MK0512GPG048-I/7MX supports PLC I/O module designs because of its 120 MHz core, deterministic interrupt response, and 5V-tolerant GPIO with 22 mA drive for direct relay and optocoupler interfacing. The 512 KB ECC Flash stores ladder-logic interpreters or IEC 61131-3 runtime firmware, while the 64 KB SRAM buffers scan-engine memory maps. The CAN FD peripheral enables backplane communication with the PLC processor at multi-Mbit/s rates. The 48-VQFN footprint is suitable for slice I/O modules mounted on DIN rails. This makes it ideal for digital-input modules, analog-output modules, and high-density I/O slices.

設計ノート
The 48-VQFN (6x6 mm) package requires careful PCB layout. The exposed thermal pad (pin 48) MUST be soldered to a ground copper pour with multiple thermal vias (typically 4-9 vias at 0.3 mm drill) to dissipate heat and provide a low-impedance ground return. Decouple each VDD pin (pins 5, 21, 37) with a 100 nF ceramic capacitor placed within 5 mm trace distance, plus a bulk 10 uF tantalum or ceramic capacitor nearby. For CAN FD signals, route the bus as a 120 ohm differential pair with controlled impedance and keep stub lengths under 1/10 of the rise time to avoid reflections at 5 Mbit/s.
Estimated: at 120 MHz core clock and full peripheral activity (CAN FD, ADC, PWM all running), the PIC32MK0512GPG048-I/7MX typically draws 60-80 mA from VDD. For a 3.3V rail, this implies 200-265 mW of MCU power dissipation. Under automotive load-dump conditions (transient up to 40V on 12V rails), add a TVS diode and common-mode choke on the supply input. Use a low-dropout regulator rated for at least 200 mA with 100 mV max dropout to ensure regulation during cold-crank events on 12V battery systems.
Common pitfalls with the PIC32MK0512GPG048-I/7MX include: (1) failing to solder the exposed pad, causing thermal runaway and unreliable ground; (2) omitting the VBAT decoupling capacitor (pin 47) when using the RTC, which causes RTC drift and corruption; (3) routing OSC1/OSC2 traces over noisy signal lines, leading to PLL jitter; (4) using a single ground plane without splitting analog/digital returns, which couples ADC reference noise into the digital logic; (5) forgetting to set the JTAG/ICSP pins to GPIO mode in code, leaving them disabled after programming. Refer to the PIC32MK Family Data Sheet section on configuration bits for full details.
