PIC32MX675F256LT-80V/PT Übersicht
A 32-bit microcontroller (MCU) is a programmable system-on-chip that integrates a high-performance processor core, program and data memory, and a rich set of peripherals into a single IC. The PIC32MX675 series sits within Microchip's PIC32 family, which targets embedded applications requiring connectivity (USB, Ethernet), graphical HMI (via PMP/parallel master port), and real-time control. In the broader product hierarchy, an MCU is a type of microcontroller -> embedded processor -> semiconductor IC. The "MX" naming convention indicates the MIPS-based M4K core family.
Key differentiating specifications include: 256KB (256K x 8) Flash program memory, 64KB SRAM, 83 general-purpose I/O lines, a 16-channel 10-bit ADC at up to 1 Msps, five 16-bit timers, two I2C, two SPI, two UART, USB-OTG (host/device/On-The-Go), 10/100 Mbps Ethernet MAC with MII/RMII interface, two I2S/SPDIF audio interfaces, a Parallel Master Port (PMP) for graphics/parallel memory, and DMA with 8 channels. Supply voltage is 2.3V to 3.6V (nominal 3.3V), and operating temperature range is -40C to +105C (industrial grade "V" suffix). The "T" suffix denotes tape-and-reel packaging, while "80" denotes 80 MHz max frequency.
The architecture combines a Harvard-style bus with separate instruction and data paths to Flash/SRAM, allowing simultaneous fetch and data access. Peripherals are connected via a peripheral bus matrix with DMA support, offloading data movement from the core. The 10/100 Ethernet MAC integrates an MII/RMII interface that connects to an external PHY such as the Microchip KSZ8041 or DP83848, eliminating the need for an external network processor. USB-OTG support enables both host and device roles, useful for embedded peripherals that must act as either.
Typical applications include industrial Ethernet gateways and PLCs, USB-enabled data acquisition modules, embedded web servers, home automation controllers, medical telemetry devices, point-of-sale terminals, and graphical HMI panels. The combination of Ethernet, USB-OTG, and PMP graphics support makes this MCU particularly suited to networked HMI products where a single chip must handle both communications and display.
When designing with this MCU, ensure that the 3.3V supply is well regulated with low noise to avoid corruption of ADC and Ethernet signals. The Ethernet MAC requires an external PHY (e.g., KSZ8041), 25 MHz reference clock, and proper MII/RMII termination. JTAG/ICSP programming requires the standard Microchip 4-wire interface plus a dedicated programming header footprint.

Wichtigste Unterscheidungsmerkmale
- Integrated 10/100 Ethernet MAC plus USB-OTG in one MCU (vs. PIC32MX575F512L-80V/PT)
- Larger SRAM and Flash vs MX460 family (vs. PIC32MX460F512L-80V/PT)
- Tape-and-reel packaging ("T" suffix) for SMT production (vs. PIC32MX675F256L-80V/PT)
Designhinweise
The PIC32MX675F256LT-80V/PT requires a regulated 3.3V supply within the 2.3V to 3.6V range. Use an LDO such as the Microchip MCP1700-3302E (250 mA) for low-noise, low-quiescent applications, or a switching regulator for higher efficiency. Place the regulator output bypass with a 10 uF tantalum or ceramic cap in parallel with a 0.1 uF ceramic cap within 5 mm of the VDD pins. Analog supply AVDD should be filtered through a ferrite bead and bypassed with 10 uF + 0.1 uF to minimize ADC and Ethernet noise.
Place the 20 MHz or 8 MHz external crystal within 5 mm of the OSC1/OSC2 pins, with short traces and a ground plane cutout to minimize stray capacitance. Route the Ethernet MII/RMII signals as 50 ohm controlled-impedance traces, length-matched within 50 mils of each other to satisfy the IEEE 802.3 timing spec. Place the KSZ8041 PHY close to the MCU and add 49.9 ohm 1% termination resistors on the differential TX/RX pairs to ground.
Do not assume USB-OTG VBUS current is sufficient - the device cannot power a USB peripheral without external 5V boost circuitry; use a load switch or boost regulator for bus-powered USB designs. Ethernet RMII mode requires a 50 MHz reference clock, not 25 MHz, on the REFCLKO pin when using the PIC32MX675 MAC in RMII configuration. Always enable the JTAG/ICSP pins for in-circuit programming during layout - leaving them unbonded makes field firmware updates impossible.
The 10/100 Ethernet MAC's MII interface runs at 25 MHz and RMII at 50 MHz; ensure all MII/RMII traces are length-matched to within 1 cm to avoid timing violations. Series-terminate the MII/RMII data lines with 33 ohm resistors near the MCU driver pins to damp reflections. USB-OTG D+/D- traces should be 90 ohm differential impedance and length-matched to within 150 mils to meet USB 2.0 full-speed signal-integrity requirements.
