PIC32MX675F512HT-80I/PT Descripción general
A 32-bit microcontroller (MCU) is a microprocessor core integrated with program memory (Flash), data memory (SRAM), and peripherals (UART, SPI, I2C, timers, ADC, communication controllers) on a single chip. The PIC32MX family is positioned in the hierarchy as follows: PIC32MX -> 32-bit MCU -> microcontroller -> embedded processor -> semiconductor. Microchip's PIC32MX6xx/7xx sub-family specifically targets connectivity applications by integrating Ethernet and USB on-chip, eliminating the need for external controllers and reducing BOM and board area.
Key features of the PIC32MX675F512HT-80I/PT include an integrated 10/100 Mbit Ethernet MAC with RMII/MII PHY interface, USB 2.0 full-speed OTG, 16-channel 10-bit 1 Msps ADC, five 16-bit timers/counters, four UART, three SPI, two I2C, and 53 general-purpose I/O pins. The 80 MHz core delivers 1.56 DMIPS/MHz, supporting DSP extensions for signal-processing workloads.
The PIC32MX6xx architecture uses a 5-stage pipeline Harvard core with hardware multiply/divide and DSP ASE, allowing deterministic interrupt response and efficient C-language execution. The wide peripheral set and dual connectivity (Ethernet + USB) make it well suited for IoT gateways and industrial control where multiple communication interfaces are required.
Typical applications include industrial IoT gateways, USB-enabled embedded devices, Ethernet-attached sensor hubs, HMI touch panels, and consumer electronics with web configuration interfaces. The 512 KB Flash supports over-the-air (OTA) firmware updates with room for dual-image bootloaders.
When designing with this MCU, allocate at least 64 KB of Flash for the MPLAB Harmony framework if Ethernet/USB stacks are enabled. Use the integrated PHY clock to free an oscillator pin and add an external 25 MHz crystal directly between OSC1/OSC2 with appropriate load capacitors for Ethernet operation.

Aplicaciones típicas
PIC32MX675F512HT-80I/PT es adecuado para 6 aplicacións: Industrial IoT Gateway, USB-Enabled Embedded Device, Ethernet-Attached Sensor Hub, HMI Touch Panel Controller, Consumer Web-Configuration Device, Motor Control Front-End.
Industrial IoT Gateway
The PIC32MX675F512HT-80I/PT fits industrial IoT gateways thanks to its integrated 10/100 Ethernet MAC and USB 2.0 OTG, which eliminate external connectivity ICs. The 80 MHz MIPS M4K core runs the MPLAB Harmony TCP/IP stack with 124 DMIPS throughput, while 512 KB Flash holds the full Harmony framework plus application logic with room for OTA dual-image bootloaders. The 128 KB SRAM plus 64 KB auxiliary buffer RAM is sufficient for concurrent Ethernet, USB, and Modbus TCP workloads. Operating from 2.3 V to 3.6 V at -40 C to +85 C, it tolerates industrial supply rails and ambient temperatures without derating.
Recomendado
USB-Enabled Embedded Device
For USB peripherals such as HID controllers, data loggers, and CDC devices, the PIC32MX675F512HT-80I/PT provides USB 2.0 Full-Speed Host/Device/OTG directly on-chip. The 53 I/O pins drive user-interface buttons and LED indicators, while the 10-bit 1 Msps ADC samples analog sensors at high rate. Compared to PIC32MX5xx parts, this device adds the Ethernet MAC, but for USB-only designs the larger 512 KB Flash accommodates composite USB stacks plus vendor-specific class firmware in a single image.
Recomendado
Ethernet-Attached Sensor Hub
Sensor hubs that aggregate Modbus, analog, and digital I/O over Ethernet benefit from the PIC32MX675F512HT-80I/PT's 10/100 Ethernet MAC paired with the 16-channel 10-bit ADC. The 80 MHz core runs the Harmony TCP/IP server stack with concurrent web server handling, while 512 KB Flash stores HTTP configuration pages, JSON telemetry templates, and the sensor driver library. Industrial -40 C to +85 C operation supports outdoor or factory-floor enclosures, and the 64-TQFP package provides easy hand-solder rework for low-volume industrial runs.
Recomendado
HMI Touch Panel Controller
The PIC32MX675F512HT-80I/PT's 80 MHz core and 53 I/O pins are well matched to small HMI panels with TFT displays, capacitive touch ICs, and rotary encoders. Its 128 KB main RAM holds double-buffered framebuffers for QVGA displays, and the 512 KB Flash accommodates LVGL or emWin graphics libraries. The USB OTG port enables firmware updates from a USB stick during field service - a common requirement for installed HMI panels that lack Ethernet access.
Recomendado
Consumer Web-Configuration Device
Consumer products with embedded web configuration (printers, IP cameras, smart appliances) leverage the PIC32MX675F512HT-80I/PT's integrated Ethernet MAC plus USB 2.0 to provide both wired and USB interfaces without external controllers. The 80 MHz MIPS M4K core executes the Harmony HTTP server with AJAX-style configuration pages, while 512 KB Flash holds HTML assets and embedded JavaScript. The 2.3 V to 3.6 V supply range lets designers reuse the same MCU across 3.3 V-only and wide-tolerance 5 V USB-powered variants.
Recomendado
Motor Control Front-End
Although the PIC32MX675F512HT-80I/PT lacks dedicated motor-control PWMs, it serves as an Ethernet-connected supervisory front-end for industrial motor drives. It reads encoder feedback via SPI or quadrature input, monitors motor current via the 16-channel ADC, and reports status over Modbus TCP. Its -40 C to +85 C industrial temperature range and 2.3 V to 3.6 V supply let it mount adjacent to power stages with appropriate isolation.

Notas de diseño
The PIC32MX675F512HT-80I/PT 64-TQFP package requires a small PCB footprint but is hand-solderable with proper pad design. Provide a solid ground plane on the top layer directly under the device and stitch vias at 5 mm spacing around the perimeter to reduce EMI on the 80 MHz core clock. The 10x10 mm body allows compact routing but the inner-pin escape must use microvias or thin traces (4 mil/0.1 mm) to fan out all 53 I/O. Place the 25 MHz Ethernet PHY crystal within 5 mm of OSC1/OSC2 and guard-trace both signals to ground per the PIC32MX5XX/6XX/7XX family datasheet layout recommendations.
Estimated: The PIC32MX675F512HT-80I/PT active supply current at 80 MHz with Ethernet + USB active is approximately 80 mA typical, plus PHY and USB transceiver draw. Total 3.3 V rail budget should be at least 200 mA with 10 percent margin. Use a low-noise LDO (e.g., Microchip MCP1700 or MIC29150) followed by a ferrite bead and 10 uF ceramic + 100 nF decoupling at each VDD/VSS pair. Place 100 nF capacitors within 3 mm of every VDD pin; the 64-TQFP has multiple VDD pins that must each be decoupled independently to prevent logic-level glitches under high-speed switching.
Do not confuse the PIC32MX675F512HT-80I/PT (64-TQFP, tape-and-reel) with the PIC32MX675F512HT-80I/MR (64-QFN). Both share silicon but the QFN land pattern is not pin-compatible with the TQFP; using one footprint for the other will short adjacent pins. Also, the '675' sub-family has integrated Ethernet - do not waste PCB area routing an external MAC. Finally, do not exceed 80 MHz instantaneous needs convert the '80I' suffix to '80V' for 5 V-tolerant variants. Validate the temperature grade: 'I' = -40 C to +85 C industrial, not -40 C to +125 C extended.
The integrated Ethernet MAC uses RMII or MII to an external PHY; route the 50 MHz RMII clock as a length-matched group and keep RMII traces under 50 mm with 50 ohm characteristic impedance on a 4-layer stackup. For USB, the 12 MHz Full-Speed clock and DP/DM differential pair must be 90 ohm differential and length-matched within 150 mil (3.8 mm). Place common-mode chokes on DP/DM if the device is near switching noise sources. Keep the 25 MHz PHY crystal traces short and symmetric; ground the can to reduce radiated emissions.
