PIC32MK0256MCJ048-E/Y8X - 80MHz 32-bit MCU, 256KB Flash, CAN-FD | Microchip
MPN: PIC32MK0256MCJ048-E/Y8X ✓ Hoạt độngPIC32MK0256MCJ048-E/Y8X Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (RAM), and a rich set of peripherals onto one die. Within the semiconductor taxonomy, the PIC32MK sits as: microcontroller -> embedded processor -> 32-bit MCU -> motor-control/IIoT class. The "MC" in the part number designates the motor-control variant, while "J048" indicates 256 KB Flash / 64 KB RAM in a 48-pin TQFP. The "-E" suffix designates the -40C to +125C extended operating-temperature grade, and "Y8X" denotes 48-pin TQFP with tape-and-reel packaging.
Key features include 12-bit ADC with up to 18 analog inputs, 6 PWM channels suitable for 3-phase motor drive, 5 analog comparators, 11 timers, 8 DMA channels, CAN-FD, two I2C, two I2S, SPI, and two UART interfaces. The device also integrates ECC-protected Flash for high-reliability operation in industrial environments.
The PIC32MK silicon combines a deterministic MIPS32 microAptiv core with a hardware math accelerator and dual-bank Flash, enabling live firmware updates without CPU stall. Dedicated motor-control peripherals (high-resolution PWM, quadrature encoder interface, analog comparators with DAC references) allow sensorless or sensored FOC / six-step BLDC drive on the same chip, reducing BOM and PCB area.
Typical applications include field-oriented control (FOC) motor drives for BLDC/PMSM, industrial PLC modules, IIoT edge nodes with CAN-FD, multi-channel analog data acquisition, and digital power conversion. Its extended-temperature operation makes it suitable for factory-floor and automotive under-hood subsystems.
When designing with this part, ensure the CAN-FD transceiver is rated for the bus topology and that the 3.3V supply is decoupled with at least 100 nF + 10 uF ceramic capacitance placed within 100 mm of the VDD pins per the Microchip PIC32MK family datasheet DS60001570D.

Ứng dụng tiêu biểu
PIC32MK0256MCJ048-E/Y8X phù hợp cho 6 Áp dụngs: BLDC / PMSM Motor Drive (FOC), Industrial PLC / Automation Module, Industrial IoT Edge Node with CAN-FD, Multi-Channel Analog Data Acquisition, Digital Power Conversion / SMPS Control, Automotive Body / Chassis Subsystems.
BLDC / PMSM Motor Drive (FOC)
The PIC32MK0256MCJ048-E/Y8X is engineered for sensorless and sensored 3-phase motor control. Its 6 PWM channels with hardware dead-time insertion, 5 high-speed analog comparators with integrated DAC references, and 12-bit ADC with up to 18 channels allow a complete field-oriented control (FOC) loop on-chip. At 80 MHz the CPU executes a 10 kHz FOC cycle well within budget, leaving cycles for speed/torque PI loops and CAN-FD communication.
Được đề xuất
Industrial PLC / Automation Module
In industrial PLC and process-control modules the 256 KB ECC Flash stores ladder-logic interpreters or IEC 61131-3 runtimes, while 64 KB RAM handles process image and stack. CAN-FD connects to fieldbus networks, and dual UART/RS-485 ports link to legacy industrial sensors. The -40C to +125C extended grade supports unheated enclosures on the factory floor.
Được đề xuất
Industrial IoT Edge Node with CAN-FD
For IIoT edge nodes bridging sensor networks to cloud gateways, the PIC32MK0256MCJ048-E/Y8X facilitates CAN-FD aggregation from multiple motors or sensors, runs MQTT or OPC-UA stacks in 256 KB Flash, and uses its 12-bit ADC for direct analog sensor read-out. The DMA engine handles background data movement, allowing the CPU to focus on protocol processing.
Được đề xuất
Multi-Channel Analog Data Acquisition
With up to 18 channels of 12-bit ADC and 8 DMA channels, the PIC32MK0256MCJ048-E/Y8X is ideal for multi-channel analog front-ends. The DMA engine offloads ADC sample transfers, freeing the CPU for FFT, filtering, or threshold detection. CAN-FD or SPI serves as a fast data uplink to a host controller or display.
Được đề xuất
Digital Power Conversion / SMPS Control
The high-resolution PWM and 12-bit ADC enable digital control of switch-mode power supplies (SMPS). The PIC32MK0256MCJ048-E/Y8X can implement peak-current-mode control of a 500 kHz buck or PFC stage, while CAN-FD reports telemetry to a system controller. The math accelerator speeds up control-loop calculations.
Được đề xuất
Automotive Body / Chassis Subsystems
Beyond industrial use, the extended -40C to +125C grade suits automotive body and chassis subsystems where AEC-Q100-qualified variants are not strictly required (non-safety applications). CAN-FD integration simplifies body-network gateways, and the motor-control peripherals drive window lifts, seat adjusters, or HVAC flaps directly.

Ghi chú thiết kế
Per Microchip PIC32MK family datasheet DS60001570D, decouple every VDD/VSS pair with a 100 nF ceramic capacitor placed within 5 mm of the pin pair, plus a single 10 uF bulk capacitor on the main 3.3 V rail. Use low-ESR ceramic capacitors (X7R/X5R dielectric) with resonance frequency above 20 MHz. This decoupling strategy supports clean ADC sampling and stable oscillator operation during motor PWM switching transients.
The 48-TQFP (7x7 mm) package has a theta_JA of approximately 50-60 C/W on a 4-layer JEDEC test board. At maximum CPU activity the device dissipates under 0.5 W, giving junction temperature rise of 25-30 C above ambient - well within the -40C to +125C extended grade. For outdoor enclosures, ensure airflow or attach a small copper pour on the PCB beneath the TQFP exposed pad region.
Separate analog and digital ground planes, joining them at a single point near the VDD decoupling capacitor to avoid ground loops injecting noise into the 12-bit ADC. Keep motor PWM outputs physically separated from analog inputs by at least one ground trace; route current-sense amplifier outputs differentially to the ADC pins. Avoid routing high-current motor traces under the TQFP.
Do not leave unused I/O pins floating; configure them as outputs driven low or inputs with the internal weak pull-up enabled to avoid parasitic current and ADC channel crosstalk. Always invoke the bootloader or JTAG port configuration during initial prototype bring-up, since the PIC32MK shares the programming pins with analog functions (AN6/AN7/PGC/PGD).
