PIC32MX575F512H-80I/MR Visão geral
A PIC32MX microcontroller is a high-performance 32-bit MCU family from Microchip built on the MIPS M4K core. PIC32 sits in the broader taxonomy: microcontroller -> 32-bit MCU -> MIPS MCU -> PIC32MX family -> embedded SoC. The 32-bit datapath, dedicated USB 2.0 full-speed On-The-Go (OTG) controller, hardware CAN 2.0B module, and integrated 10/100 Ethernet MAC make PIC32MX5XX/6XX/7XX devices well suited to connected embedded designs that previously required external PHY/bridges or a separate communication companion chip.
Key features of the PIC32MX575F512H variant include 512 KB Flash, 64 KB SRAM, 51 general-purpose I/O pins, a 16-channel 10-bit ADC at up to 1 Msps, two UARTs, two SPI/I2S ports, two I2C ports, four 16-bit timers plus one 32-bit RTCC timer, five PWM/OC channels, and a parallel master port (PMP) for off-chip memory or graphics interfacing. The device operates from 2.3 V to 3.6 V, has a maximum CPU clock of 80 MHz, and supports 105 DMIPS throughput with single-cycle MAC hardware.
The architecture combines a Harvard-style 5-stage pipeline, prefetch cache to mitigate Flash wait states, and a rich peripheral set. The USB OTG controller with integrated PHY eliminates external USB transceivers, the CAN module complies with CAN 2.0B active, and the Ethernet MAC supports RMII/MII for 10/100 Mbps networking. Code is developed in MPLAB X IDE with MPLAB Harmony and programmed via ICSP or JTAG.
Typical applications include industrial USB/CAN gateways, factory automation nodes, embedded web servers, USB peripherals, point-of-sale terminals, motor control inverters, and medical instrumentation requiring USB connectivity. The integrated peripherals allow a single chip to handle communication, user I/O, and modest signal processing without external bridges.
Design with PIC32MX575F512H by first allocating a 3.3 V LDO with adequate decoupling (100 nF plus 4.7 uF bulk), then route the 8 MHz primary crystal with short traces and a guard ring to keep the PLL stable. Enable the prefetch cache module in your startup code to compensate for Flash wait states at 80 MHz.

Aplicações típicas
PIC32MX575F512H-80I/MR é adequado para 7 aplicaçãos: Industrial USB/CAN Gateway, Embedded Web Server / Ethernet Node, USB Barcode Scanner / HID Peripheral, Point-of-Sale Terminal Controller, Motor Control Inverter / PFC Front-End, Medical Data Acquisition / USB Patient Monitor, Automotive Diagnostic Dongle (CAN-to-USB).
Industrial USB/CAN Gateway
The PIC32MX575F512H-80I/MR fits industrial USB-to-CAN gateways because it integrates USB 2.0 FS OTG with on-chip PHY alongside a hardware CAN 2.0B active controller, eliminating external transceivers and bridges. Running at 80 MHz (105 DMIPS) and offering 512 KB Flash with 64 KB SRAM, it can host both USB CDC and CANopen or J1939 stacks simultaneously. Engineers typically implement the USB device or host port on one side and a CAN node on the other, using the dedicated DMA channels to offload USB endpoint transfers. The industrial -40C to +85C temperature grade and 2.3-3.6 V operation match 24 V factory-bus systems stepped down to 3.3 V.
Recomendado
Embedded Web Server / Ethernet Node
The PIC32MX575F512H-80I/MR suits embedded web servers and 10/100 Ethernet nodes because it integrates a 10/100 Ethernet MAC supporting RMII/MII, requiring only an external PHY (such as a Microchip KSZ8041) and magnetics. The 512 KB Flash accommodates a TCP/IP stack plus an HTTP server with custom pages, while 64 KB RAM holds sockets and packet buffers. At 80 MHz the M4K core can service HTTP requests, SNMP polling, and Modbus TCP concurrently. Engineers typically pair this MCU with the FreeRTOS or Microchip Harmony TCP/IP stack to deliver a sub-$15 BOM web-enabled device.
Recomendado
USB Barcode Scanner / HID Peripheral
The PIC32MX575F512H-80I/MR is well-matched to USB barcode scanners and HID peripherals thanks to its integrated USB 2.0 full-speed OTG controller with on-chip PHY, which removes the need for an external ULPI bridge. Operating at 80 MHz, the MCU can decode 1D/2D barcodes, manage HID reports, and handle button debouncing with cycle budgets under 1 ms. The 64 KB SRAM comfortably buffers scan images and HID report queues. Industrial temperature rating supports warehouse and retail point-of-sale deployments.
Recomendado
Point-of-Sale Terminal Controller
The PIC32MX575F512H-80I/MR serves as the main controller in point-of-sale (POS) terminals because it provides USB host for peripherals (barcode, printer), CAN or UART for back-office comms, and a parallel master port (PMP) for driving a character or graphic LCD. The 512 KB Flash hosts the application logic and payment stack shim, while 64 KB RAM handles transient transaction buffers. The 80 MHz CPU easily services USB polling and PMP refresh simultaneously. Industrial temperature grade and RoHS compliance suit retail deployments.
Recomendado
Motor Control Inverter / PFC Front-End
The PIC32MX575F512H-80I/MR fits digital motor control and PFC front-end designs because it delivers five 16-bit PWM channels with complementary outputs and dead-band control, plus a 1 Msps 10-bit ADC for current/voltage sampling. At 80 MHz, the M4K core can run field-oriented control (FOC) loops at 20 kHz with margin for housekeeping. The 64 KB SRAM absorbs single-cycle MAC operations and PID state without stalling. CAN 2.0B enables integration into industrial drive networks.
Recomendado
Medical Data Acquisition / USB Patient Monitor
The PIC32MX575F512H-80I/MR is well suited to medical data-acquisition front ends that need USB device connectivity to a host PC, thanks to its 16-channel 10-bit ADC at 1 Msps and integrated USB OTG. At 80 MHz, it can oversample ECG/EMG channels and stream via USB isochronous endpoints. The 512 KB Flash stores USB descriptors, signal-processing firmware, and small lookup tables, while 64 KB RAM holds sample buffers. Industrial temperature grade and RoHS compliance ease IEC 60601 integration.
Recomendado
Automotive Diagnostic Dongle (CAN-to-USB)
The PIC32MX575F512H-80I/MR enables compact CAN-to-USB diagnostic dongles for automotive service and fleet telematics by combining one CAN 2.0B channel with USB 2.0 FS OTG in a single chip. Operating at 80 MHz, it can run OBD-II parsing at full bus loads (1 Mbit/s) while streaming decoded frames over USB CDC or HID. The 512 KB Flash accommodates ISO-TP5 transport layer plus UDS stacks, and 64 KB RAM absorbs incoming frame bursts. Industrial temperature rating supports under-dash mounting.

Notas de projeto
The PIC32MX575F512H-80I/MR requires a clean 3.3 V supply capable of delivering peak transient currents up to 75 mA during PLL/USB activity. Place a 4.7 uF bulk tantalum or ceramic capacitor next to each VDD pin pair, plus a 100 nF decoupling capacitor within 2 mm of every supply pin. The USB transceiver supply (VUSBUVDD) requires its own 100 nF plus 4.7 uF capacitor to comply with USB 2.0 FS bus-power specifications.
Route the 8 MHz primary crystal traces symmetrically and within 10 mm of the OSCI/OSCO pins, surrounded by a ground guard ring tied to VSS at one point. The exposed thermal pad (EP) MUST be soldered to a 5x5 mm copper pour on the top layer with at least 6 thermal vias to inner ground planes for 80 MHz operation. Keep USB D+/D- traces as a 90 ohm differential pair with matched length within 2 mm.
At 80 MHz operation the prefetch cache module MUST be enabled in startup code (CHECONbits.PFMWS = 0, PREFEN = 11) to insert the correct Flash wait states; otherwise firmware may execute unreliably. Avoid mapping critical ISRs to shadow register sets without enabling the SRLOCK sequence. Do not drive the USB D+/D- pins before enabling the OTG module or 48 MHz USB clock, or the bus enumeration will fail.
Estimated: at 80 MHz CPU load and 3.3 V supply, the VQFN-64 (MR) package dissipates approximately 240 mW (3.3 V x 73 mA typical IDD). With 4-layer PCB copper-pour thermal pad, theta_JA is approximately 28 C/W, yielding a junction-to-ambient rise of 7 C above ambient. Industrial grade (-40C to +85C) gives adequate margin in most enclosed enclosures without forced airflow.
