PIC32MX675F512H-80I/PT 概要
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory, RAM, and programmable peripherals. The PIC32MX family uses the MIPS32 M4K core (RISC architecture) paired with Microchip's PIC peripheral ecosystem, and falls into the broader hierarchy of microcontroller -> embedded processor -> semiconductor -> integrated circuit. 32-bit MCUs like this part are typically deployed where 8/16-bit devices lack the throughput for TCP/IP stacks, graphics, or audio DSP, while still offering low enough power for battery and bus-powered products.
Key differentiating features include 512 KB Flash and 64 KB SRAM (large enough for full TCP/IP stacks plus application code), an integrated 10/100 Ethernet MAC for connected products, USB OTG for device/host/On-The-Go roles, eight DMA channels that offload data movement from the core, and a parallel master port for external bus expansion. The 53 programmable I/O pins are 5V tolerant on selected pins, simplifying mixed-voltage interfacing. Brown-out reset, power-on reset, and a watchdog timer contribute to robust embedded firmware behavior.
The architecture pairs a 32-bit MIPS core (5-stage pipeline, single-cycle multiply) with Microchip's peripheral set, supporting MPLAB X IDE, MPLAB Harmony framework, and XC32 compiler toolchains. The 80 MHz clock rate delivers 1.56 DMIPS/MHz (approximately 125 DMIPS), giving roughly two to four times the headroom of PIC24 or PIC32MX1/2/3/4/5-series predecessors for protocol processing.
Typical applications include industrial Ethernet gateways, USB-to-UART bridges, building-automation controllers, point-of-sale terminals, embedded web servers, and any connected appliance that needs an HTTP/MQTT server or USB device role. The 512 KB Flash also supports rich GUIs and over-the-air firmware update schemes.
When designing with this part, verify the 2.3-3.6 V supply window (5V tolerant I/O does not mean 5V core operation) and follow Microchip's decoupling recommendations - 100 nF plus bulk capacitance near each VDD/VSS pair is typical for stable 80 MHz operation.

主な用途
PIC32MX675F512H-80I/PT の用途: 6 件s: Industrial Ethernet Gateway, USB Device and OTG Peripherals, Building Automation Controller, Point-of-Sale (POS) Terminal, Embedded Web Server / IoT Edge Node, Industrial Sensor Hub with USB Diagnostics.
Industrial Ethernet Gateway
The PIC32MX675F512H-80I/PT fits industrial Ethernet gateways because it integrates a 10/100 Ethernet MAC and a USB OTG controller alongside 512 KB Flash and 64 KB SRAM, which is enough memory for a full TCP/IP stack plus application logic. At 80 MHz the MIPS32 M4K core can sustain Modbus TCP, EtherNet/IP, or MQTT message handling while still servicing the serial UARTs used for RS-485 fieldbus. Designers add an external PHY (LAN8720A or DP83848) and an RJ45 with integrated magnetics; the MCU's DMA channels move Ethernet traffic with minimal CPU overhead. Industrial temperature grade and the 64-TQFP package suit DIN-rail mounted controller designs.
おすすめ
USB Device and OTG Peripherals
The integrated USB OTG full-speed controller makes this MCU a strong fit for USB peripherals such as USB-to-UART bridges, USB data loggers, and USB HID devices. The 80 MHz core handles USB protocol plus user application logic without dropping frames, while 64 KB SRAM accommodates USB ping-pong buffers and FIFO data. The PIC32MX675F512H-80I/PT's 6 UARTs can be bridged over USB to legacy RS-232/RS-485 industrial gear, and On-The-Go lets the device act as either host or device. Industrial temperature grade and lead-free TQFP packaging ease certification of industrial-grade USB products.
おすすめ
Building Automation Controller
In building automation hubs, the PIC32MX675F512H-80I/PT consolidates Ethernet (for BACnet/IP or Modbus TCP), USB (for commissioning/wifi dongles), and multiple serial channels to talk to HVAC, lighting, and access-control subsystems. The 53 I/O pins drive relays and read digital sensors, while the 10-bit 16-channel ADC handles analog inputs such as temperature, humidity, and 4-20 mA transducer loops. With 512 KB Flash the part fits a full BACnet/IP stack plus custom application code, and the watchdog plus brown-out reset keep fielded controllers reliable across long deployments.
おすすめ
Point-of-Sale (POS) Terminal
POS terminals benefit from the PIC32MX675F512H-80I/PT's mix of Ethernet (LAN backhaul), USB OTG (cash-drawer, printer, customer display), and 53 GPIOs for keypad and magnetic-stripe readers. The 80 MHz MIPS core and 512 KB Flash fit embedded web servers and TLS-lite libraries, while the 64 KB SRAM handles transaction buffering. The industrial temperature rating and lead-free TQFP package suit retail-environment reliability requirements, and the integrated peripherals cut BOM cost versus an MCU + external MAC + external USB chip solution.
おすすめ
Embedded Web Server / IoT Edge Node
The 512 KB Flash and 64 KB SRAM on the PIC32MX675F512H-80I/PT fit a lightweight HTTP server with REST endpoints, plus an MQTT or CoAP client for cloud telemetry. The integrated Ethernet MAC plus USB OTG give the node both wired IP connectivity and the option of a USB Wi-Fi or cellular dongle. The 80 MHz core comfortably runs Microchip's MPLAB Harmony TCP/IP stack with TLS handshakes for a few seconds, suitable for configuration portals and telemetry uplinks. 5V-tolerant I/O pins simplify connection to legacy industrial sensors.
おすすめ
Industrial Sensor Hub with USB Diagnostics
A multi-channel industrial sensor hub uses the PIC32MX675F512H-80I/PT's 16-channel 10-bit ADC to read analog transducers (4-20 mA, 0-10 V, thermocouples via front-end conditioning), the UARTs/SPI/I2C to read digital sensors, and USB OTG to expose live readings to a laptop or HMI. The 53 GPIOs handle alarm outputs, relay drivers, and keypad inputs. Industrial temperature grade (-40C to +85C) plus Microchip's brown-out reset and watchdog timer keep the hub reliable in factory floors.

設計ノート
Estimated: at 80 MHz, VDD = 3.3 V, all peripherals enabled, typical active current is about 70-90 mA for the PIC32MX675F512H-80I/PT. Use a 3.3 V LDO with at least 200 mA headroom (e.g., MCP1700-3302E for low-power or AP2112K-3.3 for higher current) plus a 100 nF decoupling capacitor on each VDD/VSS pair and a 10 uF bulk capacitor. Apply power-on reset discipline: keep VDD rise time within Microchip's specification (typically 0.05-10 ms) and ensure the brown-out reset voltage (BOR) is enabled in the configuration bits for field reliability.
Route the 80 MHz system traces (parallel master port, oscillator, USB D+/D-) with controlled impedance and length matching. USB D+/D- traces should be 45 ohm single-ended, 90 ohm differential, and kept as short as possible with a continuous ground reference plane underneath. Place the 32 kHz crystal (SOSC) and main oscillator (OSC1/OSC2) close to the MCU, with guard traces around the oscillator pins. The Ethernet RMII/MII signals to the external PHY should be length-matched (within 50 mils) and routed over a solid ground plane for EMI control.
Do not assume 5V tolerance across all I/O - only specific pins (shaded in the datasheet pin table) are 5V tolerant. Always enable the watchdog timer in firmware before deploying fielded products, and configure the brown-out reset to the lowest acceptable VDD threshold to avoid corruption on brown-out events. JTAG/ICSP pins (TMS, TCK, TDO, TDI, PGECx/PGEDx) must be left in their default mode or properly reconfigured if used as GPIO, otherwise debug access is locked. Verify configuration bits in code to avoid inadvertently disabling the PLL or USB clock.
