PIC32MX775F512H-80I/PT 概要
A 32-bit microcontroller (MCU) is a single-chip processor with on-chip Flash, SRAM and peripherals that executes instructions on 32-bit data paths. PIC32 devices extend Microchip's PIC architecture into the MIPS32 M4K core, sitting at the high-performance end of the PIC family above 8-bit PIC16/PIC18 and 16-bit PIC24/dsPIC. They run C/C++ firmware with industry-standard toolchains and are supported by MPLAB X IDE and MPLAB Harmony framework.
Key features include a 5-stage pipeline core delivering 105 DMIPS at 80 MHz, hardware multiplier/divider for DSP-class math, USB 2.0 OTG with integrated PHY, parallel master port (PMP) for external bus/graphics, two I2C, two SPI, six UART, two CAN 2.0b modules, 16-bit timers/capture/compare/PWM and a 16-channel 10-bit ADC at 1 Msps. Operating voltage is 2.3 V to 3.6 V, junction temperature -40 °C to +105 °C (industrial).
Typical applications are industrial Ethernet nodes, CAN-bridge gateways, USB-OTG devices, multi-protocol sensor hubs, point-of-sale terminals, HVAC controllers and graphics HMI with PMP. Engineered for deterministic real-time performance, the integrated DMA offloads USB, Ethernet and CAN from the core, leaving headroom for the application stack.
Design tip: route Ethernet differential pairs (TPIN+/-, TPOUT+/-) with 100 Ω controlled impedance and place the 50 MHz RMII crystal within 10 mm of the OSCI/OSCO pins to meet IEEE 802.3 timing.

主な用途
PIC32MX775F512H-80I/PT の用途: 6 件s: Industrial Ethernet Sensor Node, CAN Bus Gateway with USB-OTG Diagnostic, USB-OTG Point-of-Sale Terminal, HVAC Controller with Touch HMI, Multi-Protocol IoT Gateway, Industrial Robotic Motion Controller.
Industrial Ethernet Sensor Node
The PIC32MX775F512H-80I/PT is a strong fit for industrial Ethernet sensor nodes thanks to its integrated 10/100 Mbps MAC with MII/RMII interfaces and 128 KB SRAM for packet buffers. With an external KSZ8041 PHY, the MCU sustains TCP/IP throughput while running Modbus/TCP and MQTT stacks on top. The 80 MHz MIPS32 M4K core leaves ~30% CPU headroom for application code, and the 8 dedicated DMA channels offload Ethernet, USB and CAN traffic from the core. Operating voltage 2.3-3.6 V lets the design run from a 3.3 V LDO powered by a 24 V industrial bus.
おすすめ
CAN Bus Gateway with USB-OTG Diagnostic
In a CAN gateway, the PIC32MX775F512H-80I/PT uses its two CAN 2.0b modules to bridge J1939 traffic to a host PC via USB 2.0 On-The-Go. The 512 KB Flash fits a full TCP/IP+J1939 stack with custom diagnostics, while the hardware crypto engine secures firmware updates. Designers route the CAN bus to physical-layer transceivers like MCP2551 and use the USB OTG with integrated PHY for plug-and-play host connectivity, eliminating an external PHY chip.
おすすめ
USB-OTG Point-of-Sale Terminal
The PIC32MX775F512H-80I/PT hosts USB 2.0 OTG with integrated PHY, eliminating the need for an external ULPI transceiver and reducing BOM cost in POS terminals. The 80 MHz core runs LCD graphics via the parallel master port (PMP) and processes EMV card transactions in real time. With 51 I/O pins, the MCU interfaces a thermal printer, NFC reader, keypad and 2.4-inch TFT without an I/O expander.
おすすめ
HVAC Controller with Touch HMI
For HVAC controllers, the PIC32MX775F512H-80I/PT drives a resistive-touch HMI via the PMP while reading thermistor inputs through the 16-channel 10-bit ADC at 1 Msps. The 105 DMIPS performance supports predictive HVAC control algorithms and BACnet MS/TP on UART. Industrial -40 °C to +105 °C temperature rating handles unconditioned mechanical-room environments.
おすすめ
Multi-Protocol IoT Gateway
The PIC32MX775F512H-80I/PT acts as a multi-protocol IoT gateway with USB OTG, Ethernet and CAN bridging Wi-Fi/BLE dongles to industrial backbones. With 512 KB Flash and 128 KB SRAM, the MCU runs TCP/IP, MQTT-SN and CoAP stacks concurrently while a FreeRTOS port manages task scheduling. The 8 DMA channels service USB, Ethernet and CAN data paths without CPU intervention, leaving headroom for OTA firmware updates.
おすすめ
Industrial Robotic Motion Controller
In robotic motion control, the PIC32MX775F512H-80I/PT generates up to 5 PWM channels with 16-bit resolution for servo drives while monitoring quadrature encoders via input capture. The deterministic 5-stage pipeline delivers predictable interrupt latency for safety-critical motion profiles. Dual CAN 2.0b interfaces connect to servo amplifiers in a daisy-chained topology, while Ethernet enables remote telemetry to a supervisory PLC.

設計ノート
Route Ethernet MII/RMII differential pairs (TPIN+/-, TPOUT+/- or RXD/RTXCLK/RXD0-1) as 100 Ω controlled-impedance traces with maximum length 50 mm to meet IEEE 802.3 timing margins. Place the 50 MHz RMII crystal within 10 mm of OSCI/OSCO (pins 31/32) and surround it with a ground pour stitched with vias every 3 mm. Decouple each VDD pin (13, 20, 30, 50, 64) with a 100 nF X7R ceramic placed within 3 mm of the pin, plus a bulk 10 µF tantalum near the package.
The PIC32MX775F512H-80I/PT draws up to 75 mA core current plus 30 mA I/O at 80 MHz with all peripherals active; use a 3.3 V LDO capable of at least 150 mA (e.g., MCP1825). Connect all five VDD pins (13, 20, 30, 50, 64) to the 3.3 V plane and all five VSS pins (19, 29, 49, 63 and pin 1 thermal pad equivalents) to a solid ground plane to minimize switching noise on the internal PLL. Add a ferrite bead between digital VDD and analog AVDD if driving sensitive ADC inputs.
Do not enable USB OTG pull-up resistors in firmware before VBUS is stable, otherwise the USB PHY can back-power the host port and damage the upstream device. Always deassert the chip select on the Ethernet PHY (e.g., KSZ8041) during boot-up and re-enable after the PLL is locked to avoid SPI/Ethernet bus contention. The MCLR pin (17) requires a 10 kΩ pull-up to VDD and a 100 nF cap to ground for clean reset; omitting the cap may cause sporadic brown-out resets in noisy industrial environments.
