PIC32MX675F512LT-80I/PF Visão geral
What is a PIC32MX microcontroller? The PIC32MX family is Microchip's MIPS-based line of 32-bit microcontrollers, sitting above the 16-bit PIC24/dsPIC and below the Cortex-M class in computational throughput. PIC32MX devices combine a Harvard architecture with single-cycle flash access, a rich peripheral set, and are programmed using MPLAB X IDE with MPLAB XC32 compilers. The 'MX5/6/7' sub-family specifically targets connected-embedded applications by integrating Ethernet MAC and USB on-chip.
Key features of the PIC32MX675F512LT-80I/PF include 53 general-purpose I/O pins, two I2C, two SPI, and four UART interfaces, a 16-channel 10-bit ADC at 1 Msps, five 16-bit timers/counters, and a parallel master port for external bus expansion. The on-chip Ethernet MAC requires an external PHY (such as the LAN8720A or DP83848) to complete an MII/RM10 interface, while the USB OTG controller can operate in Host, Device, or On-the-Go mode with an external PHY-less transceiver.
Architecturally, the PIC32MX675F512L series employs a five-stage MIPS pipeline, prefetch cache to mask flash wait states, and a separate bus for peripherals. The device operates from a single 2.5-3.6 V supply, includes a 32 kHz low-power secondary oscillator for RTCC, and supports five low-power sleep modes for battery-backed designs.
Typical applications include industrial Ethernet gateways, building-automation controllers, point-of-sale terminals, embedded web servers, USB peripherals, and CAN-connected sensor nodes. The combination of deterministic interrupt latency, large SRAM for TCP/IP stacks, and dual connectivity interfaces makes it well suited to connected industrial designs.
When designing with this part, ensure the Ethernet PHY RM10 reference clock is sourced correctly and that the 25 MHz or 50 MHz main oscillator is used, not the internal 8 MHz RC. Decouple AVDD and VDD separately with 0.1 uF and 10 uF capacitors placed within 5 mm of the package pins.

Aplicações típicas
PIC32MX675F512LT-80I/PF é adequado para 7 aplicaçãos: Industrial Ethernet Gateway, USB HID / Device Peripheral, Building Automation Controller, POS Terminal / Embedded Payment Device, Embedded Web Server / IoT Edge Node, CAN-Connected Sensor Hub, Audio / Voice over IP Endpoint.
Industrial Ethernet Gateway
The PIC32MX675F512LT-80I/PF is well suited to industrial Ethernet gateways because it combines an integrated 10/100 Ethernet MAC with 128 KB of SRAM, which is sufficient to run Microchip's MPLAB Harmony TCP/IP stack alongside an RTOS. With 80 MIPS of throughput, the device can route Modbus/TCP, EtherNet/IP, or MQTT messages while servicing CAN, SPI sensors, and GPIOs simultaneously. The 8 DMA channels offload memory-to-memory and peripheral-to-memory transfers, reducing CPU load in high-traffic gateway designs.
Recomendado
USB HID / Device Peripheral
The PIC32MX675F512LT-80I/PF integrates USB 2.0 Full-Speed OTG, allowing it to act as USB device, host, or On-the-Go without an external transceiver IC. The 80 MHz MIPS core and 128 KB RAM comfortably handle USB stacks, HID class drivers, and CDC ACM bridges, while the 53 GPIOs provide ample headroom for buttons, LEDs, and segment-LCD interfaces. The device's small-footprint TQFP-100 package suits compact USB peripherals such as HID input devices, custom instrumentation, and USB-to-UART bridges.
Recomendado
Building Automation Controller
In building automation the PIC32MX675F512LT-80I/PF handles BACnet MS-TP or Modbus RTU over two CAN channels and four UART interfaces, while the Ethernet MAC provides BACnet/IP or web-server connectivity. The 16-channel 10-bit ADC at 1 Msps reads thermistor, humidity, and analog sensor channels, while the parallel master port drives external LCD or segment displays. Industrial-grade -40C to +85C operation and 2.5-3.6 V supply support 24V-bus systems via a step-down LDO.
Recomendado
POS Terminal / Embedded Payment Device
POS terminals benefit from the PIC32MX675F512LT-80I/PF's Ethernet MAC for IP-based payment connectivity, USB OTG for PIN-pad or printer peripherals, and 128 KB SRAM for transaction buffers and TLS handshakes. The 512 KB Flash accommodates encrypted firmware images with Microchip's secure-boot extensions, while the 80 MHz MIPS core supports AES/SHA acceleration in software. The TQFP-100 package fits compact POS form factors.
Recomendado
Embedded Web Server / IoT Edge Node
The PIC32MX675F512LT-80I/PF can host a small embedded web server using Microchip's Harmony Net Services, exposing REST endpoints or MQTT topics without external memory. 128 KB RAM is sufficient for a typical HTTP server with TLS lite, while the Ethernet MAC and 8 DMA channels offload TCP/IP packet handling. Industrial -40C to +85C operation and a 2.5-3.6 V supply suit factory-floor installations, while the 53 onboard ports interface directly to sensors and actuators.
Recomendado
CAN-Connected Sensor Hub
With two independent CAN modules, the PIC32MX675F512LT-80I/PF acts as a CAN hub bridging sensor arrays on one bus with actuator controllers on another, or providing CAN-to-Ethernet/CAN-to-USB bridging. The 80 MHz MIPS core and 8 DMA channels handle CAN-FD payloads at 1 Mbps, while 16 ADC inputs digitize analog sensor data before forwarding on the bus. Industrial -40C to +85C operation and 2.5-3.6 V supply support vehicle and factory CAN bus environments.
Recomendado
Audio / Voice over IP Endpoint
The PIC32MX675F512LT-80I/PF's 80 MIPS performance and 128 KB RAM are sufficient to run VoIP signaling stacks (SIP) and small audio buffering, while the integrated Ethernet MAC provides IP connectivity and the 16-bit ADC could digitize microphone inputs at voice sample rates. The 2.5-3.6 V supply and small TQFP-100 package suit compact desk-phone or intercom form factors. Designers should pair with an external audio codec such as the AIC23B for full-duplex voice.

Principais diferenciais
- Integrated 10/100 Ethernet MAC plus dual CAN modules in a single TQFP-100 device (vs PIC32MX575F512LT-80I/PF)
- Tape and reel packaging for high-volume SMT assembly (vs PIC32MX675F512L-80I/PF)
- Industry-standard MIPS32 M4K core with mature MPLAB Harmony software stack (vs PIC32MX664F128LT-I/PF)
Notas de projeto
The PIC32MX675F512LT-80I/PF requires separate analog and digital supply pins (AVDD/AVSS, VDD/VSS). AVDD must be tied to the same 3.3 V rail as VDD, but a ferrite bead plus 10 uF + 0.1 uF decoupling network on AVDD is recommended to keep ADC reference clean. A common-mode choke between AVDD and VDD reduces ADC noise coupling by 10-15 dB. Decouple each VDD pin with its own 0.1 uF ceramic placed within 5 mm of the pin - never share a single decoupling capacitor across multiple VDD pins.
For the TQFP-100 (PF) 14x14 mm package, use a 4-layer PCB stack-up with a continuous ground plane on layer 2 to provide both thermal dissipation and controlled impedance for high-speed signals. The Ethernet RMII traces must be 50 ohm single-ended, length-matched within 50 mils, and routed on the top layer with the ground plane 0.2 mm below. Use a 1:1 Ethernet transformer on the MDI lines with center taps tied to a clean 2.5 V or 3.3 V via a 49.9 ohm + 0.1 uF network per IEEE 802.3.
Do not enable the on-chip Ethernet MAC without a 50 MHz or 25 MHz reference clock on the ERCLK pin - the MAC requires an external PHY reference and will not lock without it. Setting OSCCON for the primary oscillator with PLL must follow the unlock sequence in Section 6 of the PIC32MX5XX6XX7XX datasheet; failures typically show as a runaway clock rather than a clean error. Pin 99/100 (OSC1/OSC2) should drive a fundamental-mode crystal with load capacitors sized per crystal datasheet, typically 22 pF for an 8 MHz crystal.
