PIC32MX675F512HT-80V/MR 개요
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and a rich set of peripherals (UART, SPI, I2C, ADC, timers, I/O). The PIC32 family extends this concept into the 32-bit MIPS M4K domain, delivering 1.56 DMIPS/MHz instruction throughput with deterministic interrupt latency. PIC32MX5/6/7 series parts are differentiated from smaller PIC32 variants by their integrated Ethernet MAC, making them a sub-category of connected/IoT-ready 32-bit microcontrollers within the broader microcontroller taxonomy.
Key specifications include 80 MHz core clock with up to 80 MIPS performance, 512 KB Flash (512K x 8), 64 KB SRAM, 53 digital I/O pins, and a 2.5 V to 3.6 V single-supply voltage range with industrial-grade -40C to +105C operating range. The 64-VQFN (MR) package exposes an integrated Ethernet MAC, USB-OTG full-speed PHY interface, two I2C, two SPI, and six UART modules, plus a Parallel Master Port (PMP). The wide peripheral set lets designers drop this MCU into industrial, consumer, and IoT nodes without external connectivity silicon.
Architecturally, the device uses the MIPS M4K core with a 5-stage pipeline, hardware multiply/divide, and tightly-coupled peripherals. DMA channels offload data movement for Ethernet, USB, and SPI traffic, freeing the CPU for application code. The 10-bit ADC runs up to 1 Msps with multiple internal references, while the on-chip Ethernet MAC implements MII/RMII PHY interfaces, accelerating TCP/IP stacks in MPLAB Harmony and TCP/IP Lite libraries.
Typical applications include industrial Ethernet nodes (Modbus TCP, EtherNet/IP gateways), USB device/host peripherals (barcode scanners, HID), CAN-connected automotive accessories, IoT edge gateways, and graphical HMI controllers. The 'T' suffix denotes tape-and-reel packaging, '-80V' designates 80 MHz speed at -40C to +105C, and '/MR' identifies the 64-pin VQFN package.
Designers should allocate a 10uF + 0.1uF decoupling pair near the VDDCORE/VDDIO pins and keep the analog AV+ traces short to maximize ADC accuracy. The Ethernet MAC requires a 25 MHz or 50 MHz reference clock fed to the PHY, so crystal selection and trace routing must respect MII timing budgets.

설계 노트
Place a 10uF tantalum or ceramic bulk capacitor plus a 0.1uF ceramic decoupling capacitor on each VDD pin pair (e.g., pins 17/18 and 35/36). Route power traces wider than 0.5 mm and keep the analog AV+ pin decoupling isolated from digital switching returns. The internal 1.8V regulator powering VDDCORE requires a 10uF + 0.1uF pair with low-ESR ceramics placed within 5 mm of the pin to meet load-step transients under DMA bursts.
The 64-VQFN exposed thermal pad (EP) MUST be soldered to a PCB ground plane with at least 4 thermal vias (0.3 mm drill) connecting to an internal ground layer for proper heat dissipation. Without EP soldering, junction temperature can exceed the +105C limit at full 80 MHz operation. Keep high-speed Ethernet MII/RMII trace lengths matched within 50 mil tolerance and route the 25 MHz PHY clock away from switching power sections.
The Ethernet MII/RMII interface runs at 25 MHz or 50 MHz - keep MII data and clock trace lengths matched to within 100 mil and route over a continuous ground reference plane. The USB-OTG D+/D- pair requires 90 ohm differential impedance and a maximum length of 50 mm. Avoid routing USB and Ethernet signals parallel to each other or near switching regulator inductor nodes to minimize EMI coupling.
Do not exceed VDD = 3.6 V absolute maximum or apply voltage to any I/O pin before the VDD rail is stable, which can trigger latch-up via the ESD protection diodes. Configure unused I/O pins as outputs (driven low) or inputs with internal pull-ups enabled - never leave them floating to avoid shoot-through current. The MCLR reset pin requires a 10 kohm pull-up to VDD and a 100 nF capacitor to ground for reliable in-circuit programming.
Place the 8 MHz primary crystal or resonator within 10 mm of the OSC1/OSC2 pins and guard the traces with a ground ring to suppress noise coupling. Keep the analog AV+/AV- traces short and isolated from digital I/O. If using the on-chip Ethernet MAC with an external PHY, place the PHY within 50 mm of the MCU and route RMII traces on the top layer with no vias to maintain 50 ohm impedance control.
