PIC32MK0256GPG048-E/7MX - 32-bit 80MHz MCU, 256KB Flash, 48-VQFN | Microchip
MPN: PIC32MK0256GPG048-E/7MX ✓ Hoạt độngPIC32MK0256GPG048-E/7MX Tóm tắt
A 32-bit microcontroller (MCU) is an integrated circuit that combines a microprocessor core, program memory (Flash), data memory (SRAM), and programmable peripherals on a single silicon die. Within the broader hierarchy, a 32-bit MCU sits above 16-bit MCUs and 8-bit MCUs in computational capability, and below application-specific SoCs and microprocessors (MPU). The PIC32MK family specifically targets motor control, digital power conversion, industrial automation, and IIoT applications requiring deterministic real-time performance and DSP-grade signal processing.
Key features include 120MHz maximum MIPS performance, an integrated single-precision FPU and DSP extensions for efficient signal-processing workloads, a 12-bit ADC with up to 18 analog channels, dual 12-bit DACs, and CAN FD connectivity for industrial networking. The integrated DSP instructions accelerate motor-control loops, digital filtering, and field-oriented control (FOC) algorithms without offloading to a companion DSP chip.
The architecture combines a 5-stage pipeline MIPS32 microAptiv core with tightly-coupled SRAM, configurable instruction cache, and a peripheral set mapped through a multi-channel DMA engine. ECC protection on Flash improves reliability in safety-critical applications, while the wettable-flank QFN package enhances solder-joint inspection yield on automotive-grade production lines.
Typical applications include brushless DC (BLDC) and permanent-magnet synchronous motor (PMSM) control, industrial servo drives, solar micro-inverters, digital power conversion, CAN-FD networked sensors, and IIoT edge nodes. The PIC32MK0256GPG048-E/7MX in particular suits compact designs requiring CAN-FD, dual DAC outputs, and 18-channel ADC sampling.
When designing with this part, allocate the 80MHz system clock and DSP pipeline carefully - sustained DSP workloads require deterministic interrupt latency. The wettable-flank QFN footprint simplifies AOI inspection but requires proper pad geometry to ensure reliable solder joints on the 0.4mm pitch.

Ghi chú thiết kế
The PIC32MK0256GPG048-E/7MX requires a stable 2.3V-3.6V supply with low-noise regulation for reliable ADC operation. Place a 10 uF bulk capacitor and 0.1 uF decoupling capacitor close to each VDD pin (there are five VDD pins on the 48-VQFN). Estimated: at 80 MHz peripheral clock and full peripheral activation, the core draws approximately 30-40 mA; add 20 mA headroom for ADC sampling and CAN-FD bursts to size your LDO at 100 mA minimum.
The 48-VQFN package has an exposed thermal pad (EP) that must be soldered to a PCB thermal land with thermal vias to a bottom-layer ground pour for proper heat dissipation. Estimated: at full-load DSP operation with all peripherals active, junction temperature rise is approximately 15-20 C above ambient on a 4-layer FR4 board with 1 sq. inch copper pour. Industrial deployments should monitor junction temperature via the on-chip die-temperature sensor and derate appropriately above 85 C ambient.
The wettable-flank QFN package on the PIC32MK0256GPG048-E/7MX enables automated optical inspection of solder joints, but requires proper PCB pad design with 0.4 mm pitch. Use NSMD (non-solder-mask-defined) pads with 0.2 mm clearance to solder mask for reliable solder fillet formation. Place the 8 MHz primary crystal or oscillator within 5 mm of OSC1/OSC2 pins, with a guard ring around the crystal traces to reduce EMI coupling into analog ADC inputs.
Do not leave the MCLR pin floating; always tie MCLR to VDD through a 10 kohm pull-up resistor for normal operation, and provide a reset button for manual reset during development. Failure to configure the JTAG/Trace pins (RB0/RB1) properly will lock out ICSP programming - leave PGED1/PGEC1 accessible for in-circuit programming. The CAN-FD peripheral requires explicit configuration of bit-timing parameters; using defaults from code examples may not match your bus topology.
