PIC32MX575F256L-80V/PF - 80MHz 32-bit MCU 256KB Flash | Microchip
MPN: PIC32MX575F256L-80V/PF ✓ Hoạt độngPIC32MX575F256L-80V/PF Tóm tắt
A 32-bit microcontroller (MCU) is a single-chip computer that integrates a 32-bit processor core, program memory (Flash), data memory (SRAM), and peripherals such as timers, communication controllers, and analog blocks. The PIC32MX575 belongs to the PIC32 family which occupies the high-performance tier of Microchip's MCU portfolio, sitting above PIC24/dsPIC and below the SAME70/SAM Cortex-M7 series in terms of capability.
Key differentiating features include USB-OTG with on-chip transceiver (no external PHY required), a dedicated CAN 2.0B module for industrial networking, five 16-bit timers/captures, four UART/SPI/I2C pairs, a 16-channel 10-bit 1 Msps ADC, and a Parallel Master Port for external bus expansion. The integrated DMA controller offloads data movement from the CPU, enabling deterministic throughput for USB and CAN traffic. JTAG and 2-wire trace ports are provided for the MPLAB REAL ICE / ICD 3 debug ecosystem.
Typical applications span industrial automation (CAN nodes, sensor hubs), USB peripherals (human-interface devices, data loggers, instrumentation), and embedded networking gateways that benefit from the simultaneous USB device/host and CAN support. The PIC32MX575F256L is also a strong fit for point-of-sale terminals and medical instrumentation where deterministic performance and ample code space are required.
Designers should note the 2.5V/3.3V dual-rail requirement (core on VCAP/VDD, I/O on VDDIO), the need for proper 8 MHz primary oscillator configuration in MPLAB Harmony, and that the V variant indicates -40C to +105C operation. Compared to the lower-density PIC32MX360/PIC32MX440 series, this device adds USB-OTG, full CAN, and a parallel master port at similar clock rates.

Ứng dụng tiêu biểu
PIC32MX575F256L-80V/PF phù hợp cho 6 Áp dụngs: Industrial CAN Node / Factory Automation, USB Human Interface Device (HID) Peripheral, Embedded Data Logger with USB Mass Storage, Medical Instrumentation Controller, Point-of-Sale (POS) Terminal, USB Host Mass Storage Bridge.
Industrial CAN Node / Factory Automation
The PIC32MX575F256L-80V/PF's integrated CAN 2.0B controller with DMA support makes it well suited for industrial CANopen and DeviceNet slave nodes. At 80 MHz on the MIPS M4K core, the device handles CAN message handling at 1 Mbit/s with predictable latency, leaving CPU headroom for application logic. The 256 KB Flash accommodates full CANopen stack libraries, while the -40C to +105C temperature range (V grade) tolerates factory-floor thermal stress. Placed on a CAN transceiver like MCP2551 or TJA1050, the MCU forms a complete node requiring only a 3.3V LDO and bypass capacitors, reducing BOM cost versus discrete CAN solutions.

USB Human Interface Device (HID) Peripheral
With an integrated USB 2.0 Full-Speed OTG transceiver, the PIC32MX575F256L-80V/PF eliminates the need for an external PHY, simplifying USB HID designs such as keyboards, custom input devices, and HID-class data loggers. The 83 GPIO pins accommodate button matrices, encoders, and LED feedback, while 64 KB SRAM supports HID report buffers and protocol stacks. Microchip's MPLAB Harmony USB stack includes ready-to-use HID class drivers, reducing firmware development time. The 80 MHz MIPS core easily handles HID polling rates above 1 kHz with deterministic interrupt latency, and the 14x14 mm TQFP package supports through-hole-friendly prototyping.

Embedded Data Logger with USB Mass Storage
The PIC32MX575F256L-80V/PF combines 256 KB Flash, 64 KB SRAM, USB-OTG host mode, and the Parallel Master Port (PMP) to implement a self-contained data logger. The 10-bit 1 Msps ADC captures sensor data into SRAM, while the PMP bus interfaces to an external SD card or NAND flash via an FSMC-style interface. USB host mode enables direct file transfer to USB thumb drives without a host PC, ideal for field-deployed instrumentation. The DMA controller offloads ADC-to-memory transfers, and the 80 MHz core processes data formatting in real time, all within a compact 100-pin TQFP footprint.

Medical Instrumentation Controller
The PIC32MX575F256L-80V/PF serves as a low-cost controller in medical devices such as portable spirometers, infusion pump monitors, and patient-side display controllers. Its deterministic 80 MHz MIPS M4K core executes control loops with predictable timing, while 256 KB Flash holds safety-critical application code and self-test routines. The 10-bit ADC at 1 Msps digitizes analog sensor outputs (pressure, flow, temperature), and the integrated CAN interface communicates with adjacent medical equipment. Although not AEC-Q100 qualified, the device's documentation, traceability, and Microchip's longevity program support long-life medical product cycles.

Point-of-Sale (POS) Terminal
For POS terminals, the PIC32MX575F256L-80V/PF delivers the right combination of USB device connectivity (for PC host link), UART/SPI for peripheral I/O (magnetic-stripe readers, NFC modules), and ample GPIO for keypad scanning. The 256 KB Flash and 64 KB SRAM host a TCP/IP stack via the integrated Ethernet MAC (on compatible PIC32MX variants) or USB CDC networking, while the parallel master port drives graphical LCDs. The 80 MHz core processes payment transactions within strict latency budgets, and the 100-pin TQFP package leaves headroom for future feature expansion without PCB redesign.
Được đề xuất
USB Host Mass Storage Bridge
USB host mode on PIC32MX575F256L-80V/PF enables mass-storage class bridges that copy data between USB thumb drives and embedded systems. The integrated DMA and 64 KB SRAM buffer sustain USB transfers at full-speed rates (12 Mbit/s), while the parallel master port pushes data to external storage. The 80 MHz core handles USB enumeration and FAT file system operations. Compared to discrete USB host controllers, the integrated OTG controller reduces the BOM by $1-2 and frees board space, making the device ideal for industrial backup modules and edge data gateways that need portable storage support.

Ghi chú thiết kế
The PIC32MX575F256L-80V/PF requires two supply rails: a 2.5V core voltage generated internally from the 3.3V VDD via an on-chip LDO (decoupled on VCAP with 10uF + 0.1uF ceramic), and a 3.3V I/O rail on VDDIO/VDD pins. Place a 10uF bulk + 0.1uF bypass near each VDD pin pair, plus a ferrite bead if analog/digital grounds are separated. Total quiescent current is typically 30-40 mA at 80 MHz with all peripherals enabled, peaking to 70 mA during Flash programming.
The 100-pin TQFP (14x14 mm, /PF suffix) has 0.5 mm pitch leads and requires careful PCB layout. Use a 4-layer stack-up with continuous ground plane beneath the IC for thermal dissipation and EMI control. Keep the 8 MHz primary oscillator traces short and surrounded by ground pour; place load capacitors within 3 mm of the OSC1/OSC2 pins. The USB D+/D- traces should be 90 ohm differential and length-matched to within 2 mm; route them on the top layer only with reference ground beneath.
Do not confuse the /PF (14x14 mm) and /PT (12x12 mm) TQFP variants - they share the same pinout but require different PCB land patterns. Also note that the PIC32MX575 family has a complex configuration word set; for 80 MHz operation the PLL must be configured with the correct FRC postscaler, and an external 8 MHz crystal with appropriate load capacitance (typically 20-33 pF) is mandatory for USB full-speed operation due to its 0.25% clock accuracy requirement. Failing to enable the JTAG/trace port correctly will prevent ICD 3 / REAL ICE debugging.
