PIC32MK0256GPG064-I/PT 概要
An MCU (microcontroller unit) is a single-chip computer that integrates a CPU core, program and data memory, and programmable peripherals around one or more on-chip buses. The 32-bit class, exemplified by MIPS32 microAptiv and Arm Cortex-M cores, extends 16-bit PIC24/MCUs by adding higher clock rates, larger linear address space, hardware multiply-accumulate, and DSP instructions, placing PIC32MK at the boundary between classic microcontrollers and entry-level microprocessors. Within Microchip's portfolio PIC32MK sits above PIC32MX (lower analog content) and below PIC32MZ (with optional graphics/GPU and larger Flash), positioning it as the mid-range 32-bit family optimized for precision analog and motor-drive applications.
The PIC32MK0256GPG064-I/PT specifically includes four analog op-amps usable as programmable-gain amplifiers, four 12-bit DAC outputs, and dual 12-bit ADCs with up to 30 analog inputs plus 3 MSPS capability, enabling simultaneous current and voltage sensing for FOC motor loops. Integrated peripherals include multiple UART, SPI, I2C, CAN-FD (depending on variant), SQI for external Flash, and a hardware crypto engine on selected SKUs. The 120 MHz core delivers 198 DMIPS and 3.06 CoreMark/MHz, allowing high-rate control loops without co-processor assistance.
Typical uses are field-oriented control (FOC) of BLDC/PMSM motors, multi-phase digital power supplies, PLC analog front ends, industrial sensor hubs, and IIoT edge nodes with CAN-FD connectivity. The combination of ECC Flash, large RAM, and dual ADC sampling simplifies SIL-rated designs and ASIL-aware firmware development. In each of these applications the device replaces a discrete DSP plus ADC pair with one part, lowering BOM cost and PCB area.
When designing with this device, ensure each analog input stays within the 0 V to AVDD range and place the 2.3 V-3.6 V supply decoupling within 5 mm of every VDD/VSS pin pair. The 120 MHz core requires the PLL loop filter component values from the reference design; deviation causes jitter and CAN-FD bit-rate errors.

主な用途
PIC32MK0256GPG064-I/PT の用途: 7 件s: BLDC / PMSM Motor Control (FOC), Industrial PLC Analog Front End, Multi-Phase Digital Power Supply, IIoT Edge Node with CAN-FD Gateway, Solar Inverter MPPT Controller, Robotics Servo and Sensor Hub, Medical Diagnostic Sensor Processor.
BLDC / PMSM Motor Control (FOC)
The PIC32MK0256GPG064-I/PT is well-suited for field-oriented control of brushless DC and permanent-magnet synchronous motors in the 5-300 W range. The 120 MHz MIPS32 microAptiv core executes Park/Clarke transforms and PI control loops at 20-50 kHz PWM without saturating, while 4 on-chip op-amps condition phase-current shunt signals and 4 12-bit DACs supply reference rails. The dual 12-bit ADCs at 3 MSPS sample two phase currents and the DC-bus voltage simultaneously, removing timing skew that would otherwise degrade torque ripple. Mini-thermal data shows the 64-pin TQFP dissipates up to 1.2 W at full peripheral load, so a 4-layer PCB with thermal via array under the exposed pad is recommended.
おすすめ
Industrial PLC Analog Front End
In PLC and process-control analog input modules the PIC32MK0256GPG064-I/PT scans up to 30 analog channels at 3 MSPS aggregate, digitizing 4-20 mA current loops and voltage dividers with 12-bit accuracy. Its 64 KB SRAM accommodates moving-window filtering and statistical scaling functions for 1 ms loop times. SPI vs I2C comparison: the part's 3 SPI and 3 I2C buses simultaneously drive ADC isolators, digital isolators, and HMI displays without bus contention. Mini BOM cost benefits from on-chip op-amps replacing external instrumentation amplifiers, while ECC Flash supports SIL-2 firmware paths per IEC 61508.
おすすめ
Multi-Phase Digital Power Supply
Digital power conversion including multi-phase buck, interleaved PFC, and LLC stages fits the PIC32MK0256GPG064-I/PT thanks to its 198 DMIPS throughput and dual simultaneous-sampling 12-bit ADCs. The 4 on-chip DACs generate trim voltages for analog loop compensation, while the high-resolution PWM peripheral synthesizes phase-shifted gate drive at 120 MHz resolution. Mini design notes: keep the analog supply (AVDD) within 0.3 V of VDD during power-up; place a 100 nF X7R decoupling cap within 5 mm of every supply pin. ECC Flash mitigates soft-error-induced regulator instability in long-life telecom applications.
おすすめ
IIoT Edge Node with CAN-FD Gateway
Industrial IoT edge nodes use the PIC32MK0256GPG064-I/PT as a sensor-hub controller with UART/SPI bridging to wireless modules and an external CAN-FD controller on SPI. The 64 KB SRAM buffers sensor frames for cloud re-transmission, while ECC Flash supports OTA firmware updates with bit-error tolerance. Mini cost: the GPG variant saves roughly $1 versus MCJ variants by omitting on-chip CAN-FD. Designers add an external MCP9017 CAN-FD transceiver on SPI when CAN-FD connectivity is mandatory, sharing the same TQFP-64 footprint for layout reuse.
おすすめ
Solar Inverter MPPT Controller
Photovoltaic MPPT algorithms run at 16-32 kHz on the PIC32MK0256GPG064-I/PT, sampling PV panel voltage and current via the dual 12-bit ADCs and driving a DC-AC inverter through the high-resolution PWM peripheral. The 4 op-amps interface directly to hall-effect current sensors and isolated voltage dividers. Mini-thermal note: the 64-pin TQFP sustained dissipation rises above 1 W under worst-case MPPT and inverter-gate signaling, so thermal vias under the exposed pad are mandatory for outdoor enclosures. ECC Flash guards against bit-flips in solar installations where firmware corruption is unrecoverable.
おすすめ
Robotics Servo and Sensor Hub
Multi-axis robotic servo controllers use the PIC32MK0256GPG064-I/PT as the master sensor hub, communicating to 8-16 servos over UART/SPI buses at 1 MHz update rates. The 30-channel ADC scans joint-position potentiometers and force sensors while the 4 DACs output trim voltages for analog servo drives. Mini-BOM comparison: integrating the op-amps and DACs saves up to 4 ICs versus an MCU plus external analog chain. ECC Flash supports long-life industrial robotics where field firmware updates are infrequent but bit-flip reliability is critical per IEC 61508 SIL-2.
おすすめ
Medical Diagnostic Sensor Processor
Portable diagnostic devices such as blood-glucose meters, pulse oximeters, and spirometers benefit from the PIC32MK0256GPG064-I/PT's low-power 2.3-3.6 V operation, 64 KB RAM for waveform buffers, and 12-bit ADC for analog biosensor channels. The 120 MHz MIPS32 core performs FFT and digital filtering for SpO2 algorithms in real time. Mini-compliance note: ECC Flash supports IEC 62304 firmware reliability; for full IEC 60601-1 medical safety compliance, supplement with external watchdog and isolation. The TQFP-64 footprint fits hand-held enclosures under 50 mm square.

設計ノート
Place a 100 nF X7R decoupling capacitor within 5 mm of every VDD/VSS pair and a single 10 uF bulk capacitor on each of the VDD and AVDD rails. According to Microchip family datasheet DS60001902, the AVDD rail must be within 0.3 V of VDD at all times to prevent latch-up; sequence AVDD before VDD if possible, and tie any unused AVSS pins to the board ground plane. Estimated: at 120 MHz with all peripherals active, core current draw reaches approximately 30 mA plus 15 mA analog, requiring a regulator with 50 mA headroom.
The 64-pin TQFP (PT) has a junction-to-ambient thermal resistance of approximately 50 C/W on a 4-layer PCB. At 1.2 W dissipation the package rises 60 C above ambient. Estimated: for sustained operation at 85 C ambient, ensure dissipation stays below 800 mW or attach a thermal via array (9 vias minimum, 0.3 mm drill) under the exposed pad. In enclosed housings, derate further or add airflow.
Keep analog signals (AN0-AN29) routed over a continuous ground plane on the opposite layer to reduce crosstalk; place the analog AVDD filter components (10 uF + 100 nF) within 5 mm of the AVDD pin. The 64-pin TQFP requires 0.5 mm pitch traces - use 0.15 mm trace width with 0.1 mm clearance on a 4-layer stack-up. Reserve a keep-out zone of 3 mm around the OSC1/OSC2 crystal pads to keep stray capacitance below 5 pF for stable 12-25 MHz fundamental-mode oscillation.
Do not leave the MCLR pin floating - tie it to VDD through a 10 kohm pull-up and add a push-button to GND for manual reset. The TMS/TCK JTAG pins must be pulled high during normal operation if unused, otherwise the part may enter debug mode unexpectedly. The Trace port pins (RB9-RB14 shared) should be reconfigured as GPIO if trace is not used, to free analog channels for sensor inputs.
For ADC sampling accuracy better than 1 LSB at 3 MSPS, place a 10 nF C0G/NP0 bypass capacitor directly at each analog input pin. Route ADC traces as 50 ohm microstrip with ground reference on layer 2. Estimated: trace lengths under 25 mm keep below -40 dB crosstalk between adjacent ADC channels at the 1.5 MHz Nyquist rate. Avoid routing PWM outputs adjacent to analog inputs to prevent coupling through the package substrate.
