PIC32MX775F512HT-80V/MR - 80MHz 512KB Flash MCU | Microchip
MPN: PIC32MX775F512HT-80V/MR ✓ Hoạt độngPIC32MX775F512HT-80V/MR Tóm tắt
A 32-bit microcontroller (MCU) is a programmable processor core built on a wider data path than legacy 8/16-bit parts, allowing a single instruction to operate on 32-bit words. Within the broader taxonomy, this device sits as: microcontroller -> embedded MCU -> 32-bit MCU -> MIPS-based MCU -> PIC32 family. The PIC32MX5/6/7 series specifically targets embedded connectivity applications where on-die Ethernet plus USB and CAN reduce BOM and board area.
Key features include 512 KB Flash program memory, 64 KB SRAM data memory, 53 digital I/O pins, 80 MHz core clock (the 50 MHz figure sometimes cited refers to peripheral bus), 2.3 V to 3.6 V supply, on-chip 10-bit ADC, DMA controller, and industrial-grade -40 C to +105 C operating range. The T-suffix denotes tape-and-reel delivery for high-volume assembly.
Architecturally, the device combines a MIPS32 M4K RISC core with dedicated peripheral engines for USB-OTG, CAN 2.0, and 10/100 Ethernet MAC, allowing real-time communication workloads to run without CPU saturation. The integrated DMA offloads memory-to-peripheral transfers, leaving the core free for application logic.
Typical applications include industrial Ethernet gateways, USB-OTG device controllers, CAN-based automotive or industrial sensor nodes, embedded web servers, and home/building automation. The combination of integrated Ethernet and USB-OTG makes the PIC32MX775 particularly attractive for IoT edge nodes that must speak both protocols concurrently.
When designing, allocate sufficient decoupling on each VDD pin and connect the exposed die pad (EP) to a low-impedance ground plane for thermal dissipation and EMI performance. Verify that MPLAB Harmony stack configuration matches the exact silicon revision to avoid driver mismatches.

Ứng dụng tiêu biểu
PIC32MX775F512HT-80V/MR phù hợp cho 6 Áp dụngs: Industrial Ethernet Gateway, USB-OTG Device Controller, CAN-Based Industrial Sensor Node, Embedded Web Server, Home/Building Automation Controller, IoT Edge Gateway with Ethernet Backhaul.
Industrial Ethernet Gateway
The PIC32MX775F512HT-80V/MR is well suited for industrial Ethernet gateways thanks to its integrated 10/100 Ethernet MAC, USB-OTG, and dual CAN controllers. The 80 MHz MIPS32 M4K core processes TCP/IP stacks including lwIP and Microchip's Harmony TCP/IP lite, with the 64 KB SRAM holding typical receive/transmit buffers. The 512 KB Flash stores the application firmware and a substantial web interface. Operating from -40 C to +105 C, it handles factory-floor temperatures. Engineers commonly pair it with a Microchip LAN8720A or DP83848 PHY plus an external 25 MHz oscillator. Compared with discrete MCU plus external Ethernet controller solutions, this part reduces BOM by 2-3 components.

USB-OTG Device Controller
The integrated USB-OTG controller on the PIC32MX775F512HT-80V/MR supports both host and device modes at full-speed and high-speed USB 2.0, removing the need for an external USB controller. The 80 MHz core easily handles USB class stacks (CDC, HID, MSD) plus application logic concurrently. The 53 available I/O pins support key matrices, LCD interfaces, and sensor inputs in USB peripherals. The 64 KB SRAM provides buffer headroom for USB descriptors and bulk transfers. Engineers commonly pair it with the MCP2200 USB-UART bridge for legacy serial devices. Compared with MCUs lacking USB-PHY integration, this part saves $0.50-$1.00 BOM per node.

CAN-Based Industrial Sensor Node
The dual CAN 2.0 controllers on the PIC32MX775F512HT-80V/MR enable redundant-bus sensor node designs common in industrial automation and chassis systems. The 80 MHz MIPS32 M4K core runs CANopen and DeviceNet stacks with deterministic latency. With 53 I/O pins, the device interfaces directly to analog sensors via the 10-bit ADC and to digital sensors via SPI or I2C. The 512 KB Flash accommodates bootloader, application, and stack can handle up to 2 independent CAN networks. Industrial -40 C to +105 C temperature range meets factory and chassis deployment. Compared with MCUs having single CAN, this part enables redundant CAN topologies without an external CAN controller.

Embedded Web Server
The PIC32MX775F512HT-80V/MR's 512 KB Flash and 64 KB RAM are well matched to embedded web server designs running Microchip Harmony's HTTP server or lwIP + libhttpd stacks. The integrated Ethernet MAC eliminates the cost of an external WIZnet or Microchip ENC28J60 controller. The 80 MHz MIPS32 core serves static pages at typical Ethernet rates without saturating. The 53 I/O pins control external relays, LEDs, and analog sensors via the 10-bit ADC. Industrial -40 C to +105 C operation supports remote installations. Compared with external-Ethernet-controller solutions, this part reduces BOM by $1.50-$2.00 per node.

Home/Building Automation Controller
Building automation controllers using the PIC32MX775F512HT-80V/MR leverage USB-OTG for commissioning, Ethernet for IP-based control, and CAN for HVAC and lighting bus integration. The 80 MHz core runs a TCP/IP server, BACnet or KNX gateway, and real-time control loops concurrently. The 512 KB Flash accommodates bootloader, application, and multiple protocol stacks. The 53 I/O pins support triac controls, opto-isolated inputs, and PWM outputs for lighting dimming. Operating from -40 C to +105 C, the device handles plenum and outdoor enclosure environments. Compared with multi-chip solutions, this single MCU replaces MCU + Ethernet controller + USB controller.

IoT Edge Gateway with Ethernet Backhaul
The PIC32MX775F512HT-80V/MR is a strong fit for IoT edge gateways that aggregate sensor data over USB, CAN, or SPI and forward it to the cloud via Ethernet. The 80 MHz MIPS32 M4K core runs MQTT or HTTP client stacks plus sensor processing. With 512 KB Flash and 64 KB SRAM, the device handles TLS handshakes using mbedTLS without dropbear reservations. The integrated DMA offloads high-throughput sensor reads, leaving the core free for protocol work. The -40 C to +105 C temperature range supports outdoor enclosures. Compared with ARM Cortex-M3/M4 alternatives, this part provides integrated Ethernet + USB-OTG at lower BOM cost.

Ghi chú thiết kế
Place 0.1 uF decoupling capacitors on each VDD pin and a single bulk 10 uF tantalum or aluminum polymer capacitor close to the MCU. Connect the exposed die pad (EP) of the VQFN-64 package to a low-impedance ground plane using at least 9 thermal vias (0.3 mm diameter) for heat removal and EMI suppression. Estimated: this configuration typically yields theta_JA below 30 C/W.
PIC32MX silicon is revision-sensitive; verify the device ID with the pic32mx_get_device_id() function at boot to ensure your firmware matches the silicon revision. Microchip ships revision A3 and later revisions with subtle errata affecting the ADC and I2C peripherals. According to Microchip errata documents, using the wrong revision's firmware can lock up the USB peripheral or cause ADC drift on certain channels.
Route the USB-OTG D+ and D- traces as a 90-ohm differential pair with continuous ground reference. Keep the pair length-matched within 150 mils and avoid any via stubs. Per the Microchip PIC32MX5XX/6XX/7XX family datasheet, USB signal integrity requires a series 27-ohm resistor on each line near the MCU pin plus an external ESD protection diode array. The Ethernet MAC differential traces also require 100-ohm differential impedance to the RJ45 magnetics.
