PIC32MK0256MCJ048T-I/Y8X 概要
A 32-bit microcontroller is an integrated circuit that combines a high-performance processor core, program memory, data memory, and a rich set of peripherals on a single die. Within the broader taxonomy of microcontrollers, the PIC32MK family sits under the PIC32 umbrella (32-bit MIPS-based), which itself belongs to the microcontroller hierarchy within the embedded semiconductor product category. These devices are designed for applications that demand deterministic real-time response combined with substantial computational throughput, such as motor control, digital power conversion, and industrial IoT edge nodes.
Key features of the PIC32MK0256MCJ048 include 37 user I/O lines, 12 timers, 8 DMA channels, and an extensive communication peripheral set comprising CAN-FD, two I2C, two I2S, SPI, and two UART interfaces. The device integrates dedicated motor-control PWM peripherals with high-resolution capability, making it well suited for multi-axis field-oriented control (FOC) of PMSM/BLDC motors. Operating voltage spans 2.3V to 3.6V, and the industrial temperature range of -40C to +85C is supported on the -I grade.
The architecture leverages the MIPS32 microAptiv core with hardware multiply/divide and a 5-stage pipeline, achieving 1.53 DMIPS/MHz. DSP extensions are present for efficient signal processing of sensor data, and ECC protection on Flash improves reliability for safety-sensitive applications. The CAN-FD peripheral supports data rates up to 8 Mbps, enabling modern automotive and industrial network topologies.
Typical applications include brushless DC motor controllers, industrial automation PLCs, IIoT sensor hubs, and CAN-FD networked embedded systems. With its combination of motor-control PWMs, CAN-FD, and ample memory, the part is well aligned with multi-axis drives, robotic arm controllers, and battery management systems.
When designing with the PIC32MK0256MCJ048, ensure bypass capacitor selection uses low-ESR ceramics per the datasheet recommendation, with resonance frequency above 20 MHz. Verify that the motor-control PWM dead-time and fault-input mapping match your inverter topology during firmware bring-up to avoid shoot-through events.

主な用途
PIC32MK0256MCJ048T-I/Y8X の用途: 7 件s: Brushless DC Motor Controller, Industrial CAN-FD Network Node, Industrial IoT Sensor Hub, Robotic Arm Multi-Axis Controller, Solar Inverter Control Board, Battery Management System (BMS) Master, Programmable Logic Controller (PLC) Slice.
Brushless DC Motor Controller
The PIC32MK0256MCJ048T-I/Y8X is purpose-built for BLDC and PMSM motor control. Its dedicated high-resolution motor-control PWM modules, quadrature encoder interface, and fast 12-bit ADC for current sensing enable field-oriented control loops running at microsecond resolution. The 120 MHz MIPS microAptiv core executes FOC algorithms with low latency, while the 256 KB Flash accommodates MPLAB Harmony motor-control libraries with room for application customization. CAN-FD allows networked multi-axis drives in industrial equipment. Compared to a generic Cortex-M0 MCU, the PIC32MK's integrated analog comparators and fault input mapping shorten hardware design.
おすすめ
Industrial CAN-FD Network Node
With its integrated CAN-FD peripheral supporting data rates up to 8 Mbps, the PIC32MK0256MCJ048T-I/Y8X is ideal as a CAN-FD node in industrial automation and automotive networks. The 64 KB RAM buffers incoming CAN frames efficiently, while ECC-protected 256 KB Flash stores protocol stacks like CANopen or J1939. The wide -40C to +85C industrial temperature range and 2.3V to 3.6V supply tolerance suit 24V industrial bus systems with local regulation. Engineers pairing this MCU benefit from Microchip's free MPLAB X development environment and Harmony code configurator.
おすすめ
Industrial IoT Sensor Hub
The PIC32MK0256MCJ048T-I/Y8X serves as an IIoT edge node aggregating data from multiple sensors over its 2x I2C, 2x I2S, SPI, and UART interfaces. The 120 MHz core performs local DSP on vibration, temperature, and current signals before forwarding summaries via CAN-FD or UART to a gateway. With 256 KB Flash, it can hold TLS libraries, sensor fusion algorithms, and application firmware simultaneously. Its DMA-driven 8-channel controller offloads data movement from the CPU, leaving headroom for secure communications and over-the-air update logic.
おすすめ
Robotic Arm Multi-Axis Controller
The PIC32MK0256MCJ048T-I/Y8X suits multi-axis robotic arm controllers because each motor axis benefits from its high-resolution PWMs and QEI inputs, while the core's DSP extensions accelerate inverse-kinematics and trajectory-planning math. The 64 KB SRAM accommodates real-time control loops at kHz rates, and 256 KB Flash stores lookup tables for joint calibration. The 12 timers and 8 DMA channels orchestrate deterministic sampling across multiple axes without CPU intervention. CAN-FD provides a backbone to coordinate multiple PIC32MK controllers in larger robotic cells.
おすすめ
Solar Inverter Control Board
For solar micro-inverters and string inverters, the PIC32MK0256MCJ048T-I/Y8X offers the PWM resolution and ADC throughput needed for MPPT and grid-synchronization control loops. Its MIPS core executes DSP routines for sine-PWM generation at 50/60 Hz grid frequencies while simultaneously handling CAN-FD communications with the system controller. The 2.3V to 3.6V supply range aligns with auxiliary supplies derived from the high-voltage DC bus. The 256 KB Flash supports grid-code firmware variants per region.
おすすめ
Battery Management System (BMS) Master
The PIC32MK0256MCJ048T-I/Y8X acts as a BMS master in lithium-ion battery packs, using its CAN-FD interface to communicate with cell-monitoring modules while running balancing algorithms on the 120 MHz MIPS core. ECC-protected Flash enhances reliability for safety-critical state-of-charge calculations. The 12 timers handle cell-balancing PWM channels, and 8 DMA channels move ADC samples without CPU load. Wide temperature tolerance allows deployment in automotive and stationary storage enclosures.
おすすめ
Programmable Logic Controller (PLC) Slice
The PIC32MK0256MCJ048T-I/Y8X fits as a PLC slice I/O module, leveraging 37 I/O pins, 12 timers, and CAN-FD for backplane communications in industrial racks. The 256 KB Flash runs IEC 61131-3 runtime or proprietary ladder-logic interpreters, while the 64 KB RAM supports scan tables and process-image buffers. The deterministic interrupt latency of the MIPS microAptiv core suits hard-real-time PLC cycle times of 1 ms or less, and ECC Flash improves mean time between failures in continuous-operation plants.

設計ノート
Per the PIC32MK family datasheet, use low-ESR ceramic bypass capacitors with resonance frequency above 20 MHz on each VDD pin. Place a 100 nF decoupling capacitor as close as possible to every VDD/VSS pair, supplemented by a bulk 4.7 uF to 10 uF capacitor near the package. Analog supply AVDD requires its own filtered network to isolate ADC reference noise from digital switching transients.
Route crystal traces (OSCI/OSCO) symmetrically with short, parallel traces and a ground guard ring to minimize stray capacitance and EMI. Separate analog signal traces from PWM outputs and motor drive signals; cross at 90 degrees if necessary. Maintain a continuous ground plane beneath the MCU with stitching vias around the perimeter for high-current return paths when driving inverter stages.
When migrating from PIC32MX or other PIC32 families, verify the PPS (peripheral pin select) configuration explicitly - the PIC32MK remapping differs from older parts. Do not assume the ADC reference voltage defaults - configure VREF+/- properly before initiating conversions. Ensure motor-control PWM dead-time is configured to prevent shoot-through in your specific inverter topology.
コンプライアンス情報
RoHS compliant per Microchip product page and distributor listings; the -I temperature grade is industrial (-40C to +85C), the -E grade is extended (-40C to +125C) but is not AEC-Q100 qualified. Choose AEC-Q100-qualified PIC32 variants explicitly for automotive applications.
