PIC32MX675F512L-80V/BG Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O on one die. PIC32MX devices are Microchip's MIPS-based 32-bit MCU line, positioned above the 16-bit PIC24/dsPIC families and below the Cortex-M class in raw Dhrystone throughput, while offering competitive class peripheral density. They sit within the broader taxonomy: microcontroller -> embedded controller -> semiconductor -> integrated circuit. The 'MX675' sub-family specifically integrates 10/100 Ethernet and USB-OTG to target connected embedded designs.
Key differentiating features of the PIC32MX675F512L include: 512 KB Flash / 64 KB RAM (sufficient for full TCP/IP stacks such as Microchip's MPLAB Harmony), integrated 10/100 Ethernet MAC with RMII/MII interface (eliminating external PHY control logic for many designs), and USB-OTG full-speed support. It also includes DMA, a 16-bit Parallel Master Port for external graphics memory or bus expansion, and 5 16-bit timers plus 5 input-capture and 5 output-compare modules for motor and PWM control.
Architecturally, the PIC32MX675 uses a MIPS32 M4K core with a 5-stage pipeline and hardware multiply/divide, enabling 1.56 DMIPS/MHz (1.08 mW/MHz). The 80 MHz '80V' speed grade ensures 80 MIPS peak throughput. The device supports an industrial -40C to +105C operating range and operates from 2.3-3.6 V (the BG package variant). The peripheral set is biased toward connectivity rather than analog precision, making it a fit for industrial gateways, home/building automation, and embedded web-server designs.
Typical applications include industrial Ethernet nodes (Modbus TCP / EtherNet/IP gateways), USB-OTG device/host bridges (mass storage, HID, CDC), home automation controllers with Web UI, point-of-sale terminals, and low-resolution graphics HMI with the integrated PMP. Its 0.8 mm ball pitch BGA keeps the footprint small for handheld connected products, while exposing enough I/O for keypad scanning and display driving.
When designing with this part, ensure your PCB supports 0.8 mm pitch BGA fanout and that the supply voltage stays within 2.3-3.6 V on VDDCORE/VDDIO. Use the on-chip LDO mode to simplify dual-rail designs. The MPLAB Harmony framework ships with TCP/IP, USB, and Graphics stacks pre-validated for the PIC32MX675F512L, materially reducing firmware development time.

Typical Applications
PIC32MX675F512L-80V/BG is suitable for 6 applications: Industrial Ethernet Gateway, USB-OTG Device/Host Bridge, Home/Building Automation Controller, Point-of-Sale (POS) Terminal, Low-Resolution Graphics HMI, Connected Sensor Data Logger.
Industrial Ethernet Gateway
The PIC32MX675F512L-80V/BG's integrated 10/100 Ethernet MAC with RMII/MII interface plus 512 KB Flash / 64 KB SRAM make it a strong fit for industrial Ethernet gateway designs such as Modbus TCP / EtherNet/IP / PROFINET node controllers. The 80 MHz MIPS32 M4K core sustains wire-speed processing of TCP/IP and Modbus frames, while DMA offloads memory copies to keep the CPU available for application logic. Microchip's MPLAB Harmony TCP/IP stack is pre-validated on this exact die, removing a key firmware development risk. The 121-ball TFBGA keeps the gateway footprint small enough for DIN-rail enclosures, and -40C to +105C operation covers unheated control cabinets.

USB-OTG Device/Host Bridge
With integrated USB-OTG full-speed (Host + Device + On-The-Go role swap), the PIC32MX675F512L-80V/BG serves as a USB bridge MCU for embedded products that need to expose mass storage, HID, or CDC interfaces to a host PC or USB flash drive. The 64 KB SRAM comfortably holds USB HID report buffers plus Mass Storage sector caches. Six UARTs allow the same MCU to act as a USB-to-multi-UART bridge for legacy serial peripherals, a common industrial use case. Harmony's USB stack includes pre-validated class drivers (CDC, HID, MSD), and the BGA package fits handheld industrial terminals and POS designs.
Recommended
Home/Building Automation Controller
The PIC32MX675F512L-80V/BG's connectivity mix (Ethernet, USB-OTG, 2x I2C, 4x SPI, 6x UART) targets home and building automation controllers that need to bridge KNX/Modbus RS-485 to BACnet/IP or to expose a Web UI. The 80 MIPS throughput sustains an embedded webserver plus concurrent RS-485 polling, while the Parallel Master Port can drive a small LCD for local HMI. Six UARTs comfortably handle multiple isolated RS-485 channels for HVAC and lighting subsystems. The 53 GPIO are sufficient for keypad, LED status, and relay outputs, and the industrial -40C to +105C rating covers boiler-room and rooftop enclosures.
Recommended
Point-of-Sale (POS) Terminal
The PIC32MX675F512L-80V/BG supports POS terminal designs that need a USB-connected payment device controller plus Ethernet for back-office sync. USB-OTG can attach a PIN pad or NFC reader, while the Ethernet MAC connects to the merchant LAN. The 16-channel 10-bit ADC reads battery voltage and thermal sensor inputs on the terminal. 64 KB SRAM holds TLS handshake state plus the application event queue without external memory. The 121-ball BGA enables the compact hand-held form factor required for retail terminals.
Recommended
Low-Resolution Graphics HMI
The integrated Parallel Master Port (PMP) on the PIC32MX675F512L-80V/BG drives small TFT displays (QVGA/WQVGA) for embedded HMI panels in industrial equipment. Microchip's MPLAB Harmony Graphics Suite ships reference designs for PMP-based displays, including touch-controller drivers for the I2C/SPI peripherals. The 80 MHz throughput sustains reactive UI updates without dedicated graphics acceleration. The industrial temperature grade and 121-ball BGA footprint fit behind a small TFT in ruggedized operator panels. The Ethernet MAC also enables remote firmware update of the HMI over the network.
Recommended
Connected Sensor Data Logger
The PIC32MX675F512L-80V/BG integrates 16 ADC channels plus DMA, enabling multi-channel sensor data logging with Ethernet push of captured data to a server. DMA transfers ADC samples to RAM without CPU intervention, freeing the 80 MHz core to handle TCP/IP framing. The 64 KB SRAM buffers ~32,000 10-bit ADC samples, sufficient for short-term buffering before Ethernet transmission. Six UARTs attach to external sensor front-ends, and USB-OTG allows direct dump of logged data to a USB flash drive in field service scenarios. The -40C to +105C industrial grade supports outdoor deployment.

Key Differentiators
- Pin-compatible temperature grade flexibility (vs PIC32MX675F512L-I/BG)
- Double the Flash on same footprint (vs PIC32MX675F256L-80I/BG)
- Retains Ethernet/USB where lower-tier parts drop connectivity (vs PIC32MX664F128LT-V/BG)
Design Notes
The 121-ball TFBGA uses a 0.8 mm ball pitch, which requires microvia (laser-drilled) PCB technology for fanout. Use a 4-layer or 6-layer stack-up with the inner layers as solid ground/power planes. Place at least 4 ground balls directly under the die as thermal vias to the inner ground plane; do not rely on thermal pads in the BGA for primary heat sinking. Match trace lengths on RMII lines to the external Ethernet PHY within 50 mils to keep skew within the RMII spec.
The PIC32MX675F512L-80V/BG accepts 2.3 V to 3.6 V on VDD, but the core voltage is internally regulated. Decouple each VDD/VDDIO ball pair with a 100 nF ceramic cap placed within 2 mm of the ball, plus a bulk 4.7 uF tantalum or polymer cap. Add a ferrite bead in series with VDDIO if the board shares power with a noisy analog rail. Power-on reset requires a minimum 10 ms VDD rise time; slower rises may require an external RC reset circuit on MCLR.
Do not confuse the PIC32MX575 (no Ethernet) with the PIC32MX675 (Ethernet + USB-OTG); the two are footprint-compatible on BGA but the 575 cannot run Ethernet. Also verify the 'V' suffix means -40C to +105C, NOT automotive AEC-Q100; AEC-Q100 automotive parts are suffixed differently. The JTAG TCK pin has an internal weak pull-up - if using JTAG boundary-scan, disable the pull-up to avoid contention with the debugger. Finally, ensure VUSB is supplied when using USB-OTG in host mode.
Compliance Information
RoHS/lead-free compliant per Microchip product page. Industrial grade only; not AEC-Q100 qualified - choose AEC-Q100 variants for automotive.
