PIC32MX775F512LT-80I/PT Visão geral
A PIC32MX7xx microcontroller belongs to the MIPS32 M4K family of 32-bit RISC microcontrollers, a tier above the 8-bit PIC16/PIC18 families and below the Cortex-M class in code density. PIC32MX parts combine a 5-stage pipeline MIPS core with Microchip peripheral IP, MPLAB X IDE support, and Harmony/MLA firmware libraries. Within Microchip's PIC32 portfolio, the MX5/6/7 sub-families are differentiated by peripheral mix: MX5 lacks USB, MX6 adds USB, and MX7 adds Ethernet plus dual CAN plus parallel master port - making the MX7 the highest-integration variant of the original PIC32MX generation.
Key specifications include 1.56 DMIPS/MHz core performance, hardware Multiply/Divide unit, 16-channel 10-bit ADC at up to 1 Msps, 5 compare/PWM output modules, 5 timer/counters, four UART, two SPI, and two I2C. Internal oscillator blocks reduce BOM by allowing operation without an external crystal. The device supports industrial -40C to +85C operation, and the "80" speed grade pins maximum CPU frequency at 80 MHz.
Architecture depth: the PIC32MX7xx uses a Harvard-style bus with separate instruction and data paths into the Flash controller, allowing simultaneous fetch and read. The Ethernet MAC includes an MII/RMII interface that requires an external PHY (such as the Microchip LAN8720A or DP83848), and the USB OTG controller requires an external PHY or direct bus-powered device connection. The 16-bit PMP can interface to graphics controllers, external SRAM, or FPGA registers without an external bus bridge.
Typical applications include industrial Ethernet-connected sensor nodes, CAN-bridged HVAC controllers, USB device or embedded-host appliances, and HMI panels driving external TFT panels via PMP. Designers use PIC32MX775F512L parts whenever full-speed Ethernet, dual CAN, and USB must coexist with deterministic interrupt response.
Design tip: dedicate separate PCB layers to the Ethernet MII/USB differential pair to meet EMI/ESD targets; place the 32.768 kHz secondary oscillator crystal close to SOSC pins if using RTCC. The PT suffix indicates a 100-pin TQFP industrial-temperature variant supplied in tape and reel.

Aplicações típicas
PIC32MX775F512LT-80I/PT é adequado para 6 aplicaçãos: Industrial Ethernet PLC Nodes, CAN-Based Automotive Body Controllers, USB-OTG Industrial Data Loggers, HMI Panels with TFT Display, Smart Energy / Metering Gateways, Medical Point-of-Care Devices.
Industrial Ethernet PLC Nodes
The PIC32MX775F512LT-80I/PT is an excellent fit for industrial Ethernet PLC nodes because it integrates a 10/100 Ethernet MAC, dual CAN 2.0b, and 512 KB Flash in one 100-pin TQFP. At 80 MHz the M4K core can sustain 1.56 DMIPS/MHz for deterministic EtherNet/IP or Modbus TCP communication cycles, while the 128 KB SRAM is large enough to hold full TCP/IP stack buffers plus application tasks. The industrial -40 to +85 C rating lets it operate directly on the factory floor, and pairing it with a LAN8720A RMII PHY reduces BOM cost. Compared with discrete Ethernet MCU designs, the integration avoids an external bus-bridge ASIC and lowers PCB layer count.
Recomendado
CAN-Based Automotive Body Controllers
The PIC32MX775F512LT-80I/PT suits CAN-based automotive body controllers thanks to its two independent CAN 2.0b controllers, 85 GPIO pins, and 512 KB Flash for UDS/KWP2000 stacks. At 80 MHz the core handles CANoe-style traffic shaping with under 50 us response latency for 1 Mbps bus traffic, while 5 output-compare/PWM modules drive LED drivers, mirror actuators, or seat motors without extra timers. The 16-channel 10-bit ADC reads multiplexed sensor inputs (temperature, current, position) at 1 Msps aggregate. Compared with external-CAN-discrete designs, the dual on-chip CAN controllers cut BOM by 1-2 USD per board.
Recomendado
USB-OTG Industrial Data Loggers
The PIC32MX775F512LT-80I/PT is well suited to industrial data loggers that require USB OTG for local mass-storage offload alongside Ethernet for remote push to the cloud. Its full-speed USB 2.0 OTG controller connects to USB flash drives or hosts via the on-chip PHY, while the 512 KB Flash hosts both a USB MSD class driver and a TLS-capable TCP/IP stack. The 128 KB SRAM serves as a 60-second rolling buffer for 8 channels at 1 ksps before scheduled offload. Compared with two-chip USB+MCU solutions, the single-chip integration reduces board area by 30 percent and removes one I2C/SPI bus-bridge path.
Recomendado
HMI Panels with TFT Display
The PIC32MX775F512LT-80I/PT supports HMI panels with TFT display via its 16-bit Parallel Master Port (PMP), which connects directly to ST/Focaltech/Ilitek TFT controllers in i80 bus mode. At 80 MHz it can refresh QVGA panels at 30 fps for industrial touch interfaces while simultaneously handling Modbus TCP traffic on Ethernet. The 512 KB Flash stores fonts, bitmaps, and the touch calibration table without external storage, while 128 KB SRAM buffers a full screen at 16-bit color depth. Compared with Cortex-M0 designs, the MIPS M4K core executes LVGL GUI tasks 2-3x faster at the same clock rate.
Recomendado
Smart Energy / Metering Gateways
The PIC32MX775F512LT-80I/PT fits smart energy and metering gateways that need simultaneous Ethernet (utility LAN), USB (local config), and CAN (sub-meter bus) connectivity. Its 512 KB Flash stores MQTT-SN, DLMS/COSEM, or IEC 61850 lite stacks, and the 128 KB SRAM buffers pre-aggregation of meter telegrams before upstream publish. At 80 MHz the M4K core performs AES-128 hardware acceleration (via PIC32 peripheral libraries) for signed meter data. Compared with multi-MCU gateways, the single-chip approach reduces certification scope for IEC/UL compliance and shrinks PCB by 25 percent.
Recomendado
Medical Point-of-Care Devices
The PIC32MX775F512LT-80I/PT is used in medical point-of-care devices such as portable glucometers, infusion pump controllers, and small vital-signs monitors. Its 80 MHz MIPS core runs the signal-processing and user-interface tasks on a single chip, while the Ethernet MAC plus USB OTG enable connectivity to hospital EMR or clinician tablets. The 16-bit PMP drives 4.3-inch TFT displays with touch for patient readouts, and 16-channel 10-bit ADC samples electrochemical or optical sensors. Compared with discrete ADC+MCU designs, integration reduces FDA submission documentation scope and BOM by 2-3 USD per unit.

Notas de projeto
Decouple the PIC32MX775F512LT-80I/PT with one 10 uF bulk capacitor and one 100 nF decoupling cap on each VDD/VSS pair, placed within 5 mm of the IC pins. The analog supply AVDD requires its own 10 uF + 100 nF filter, ideally isolated from VDD by a ferrite bead to keep ADC readings clean. The internal voltage regulator requires a 10 uF capacitor on the VCAP pin (if exposed).
Route the Ethernet MII/RMII traces with controlled 50 ohm impedance on the outer layer and keep total length under 50 mm to meet 100 Mbps timing margins. The USB D+/D- pair needs 90 ohm differential impedance and matching within 0.15 mm. Place the LAN8720A RMII PHY within 25 mm of the MAC pins to minimize skew between REF_CLK and data lines.
Do not leave the ICSP pins (PGEC1/PGED1) floating - add 4.7 kohm pull-ups for production boards so programming tools work without rework. The Ethernet MAC requires an external 50 MHz oscillator or PHY-derived clock; the internal 8 MHz FRCDIV cannot source REF_CLK directly. Always run the Microchip bootloader for field firmware upgrades via Ethernet or USB rather than via ICSP.
The 100-pin TQFP has a thermal resistance (theta_JA) of approximately 39 C/W on a 4-layer JEDEC test board. At 80 MHz full load the core typically dissipates under 200 mW, keeping junction temperature rise below 8 C above ambient - no heatsink is needed. For high-ambient industrial enclosures above 70 C, verify the SoC timing margin over voltage and temperature per datasheet DC characteristics.
