PIC32MX775F512L-80V/PT Présentation
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, and a rich set of on-chip peripherals. PIC32MX7xx devices sit in Microchip's PIC32 family, which is positioned between 8-bit PIC MCUs and 32-bit ARM Cortex-M parts. Within that family, PIC32MX775 specifically adds an integrated 10/100 Ethernet MAC, USB-OTG, and dual CAN controllers - features normally requiring external components on simpler MCUs.
Key features include USB-OTG full-speed host/device, two CAN 2.0B modules, a 10/100 Mbps Ethernet MAC with MII/RMII interface, 16-channel 10-bit ADC at 1 Msps, five 16-bit timers, two I2C, two SPI, and a parallel master port. The PIC32MX775 implements the MIPS32 M4K core with single-cycle multiply, hardware multiply-accumulate, and a five-stage pipeline, enabling up to 1.56 DMIPS/MHz. A dedicated DMA controller offloads memory transfers from the CPU across peripherals.
Architecturally, the part is built on a 0.25 µm flash process, with prefetch cache to hide Flash latency at high CPU clock rates. Peripherals are connected to the CPU via a multi-layer bus matrix that allows concurrent DMA and CPU traffic to SRAM and peripheral FIFOs.
Typical applications include industrial Ethernet gateways, CAN-based automotive body controllers, USB peripherals (HID, CDC, MSD, audio class), PLCs, building-automation nodes, embedded web servers, and POS terminals. The combination of integrated Ethernet, USB-OTG, dual CAN, and 512 KB Flash removes the need for external PHY or interface ICs in many designs.
Design tip: at 80 MHz and 3.3 V, full Flash read requires the prefetch cache enabled and one wait state. Place a 100 nF decoupling capacitor on every VDD/VSS pair and a 10 µF bulk capacitor near the regulator. The Ethernet MAC still requires an external PHY (e.g., LAN8720A, DP83848); the PIC32MX775 provides only the MAC layer.

Applications typiques
PIC32MX775F512L-80V/PT convient pour 7 applications: Industrial Ethernet Gateway / SCADA Node, USB-OTG Industrial Peripheral (Data Logger, Programmer), Automotive CAN Body Controller / Gateway, Embedded Web Server / IoT Edge Node, POS Terminal / Payment Kiosk Controller, Building Automation Controller (BACnet/Modbus), Medical Data Acquisition Front-End.
Industrial Ethernet Gateway / SCADA Node
The PIC32MX775F512L-80V/PT is a strong fit for industrial Ethernet gateways because it integrates both a 10/100 Ethernet MAC and dual CAN 2.0B controllers in a single 100-pin TQFP. With 512 KB of Flash it can host a full TCP/IP stack (Microchip Harmony or lwIP) plus a CANopen or J1939 handler simultaneously. Placed between an external LAN8720A RMII PHY and two CAN transceivers (e.g., MCP2562), the MCU terminates Modbus TCP, EtherNet/IP, or PROFINET on one side and CANopen on the other. The 80 MHz M4K core sustains ~1.56 DMIPS/MHz, adequate for sub-10 ms scan cycles typical of SCADA polling. The V-grade -40C to +105C rating supports unconditioned industrial cabinets.
Recommandé
USB-OTG Industrial Peripheral (Data Logger, Programmer)
The PIC32MX775F512L's integrated USB 2.0 Full-Speed OTG controller with on-chip transceiver eliminates external USB PHY chips, reducing BOM cost by ~$1.50. For a USB data-logger or field-programmer, 512 KB Flash is sufficient for MSD + CDC + HID composite device stacks, while 64 KB RAM supports dual-buffered FAT32 SD-card writes via the Parallel Master Port. Operating from 2.3 V to 3.6 V allows direct Li-ion battery power. The -80V industrial temperature grade supports outdoor or factory-floor enclosures. Compared to an external FTDI bridge plus a smaller MCU, this single-chip solution saves PCB area and reduces firmware complexity.
Recommandé
Automotive CAN Body Controller / Gateway
The PIC32MX775F512L-80V/PT's dual independent CAN 2.0B controllers (each supporting 1 Mbps per ISO 11898-1) make it well-suited as a body-controller gateway between chassis and powertrain CAN buses. With 512 KB Flash it runs both a J1939 stack and a CANopen stack simultaneously, bridging messages between the two buses. The 80 MHz M4K core handles real-time filtering of 1 kHz message streams with negligible CPU load. An external MCP2561/MCP2562 transceiver converts the digital CAN TX/RX to the differential physical layer. Note: this part is not AEC-Q100 qualified - for full automotive qualification, evaluate the PIC32MX1/2 series or move to PIC32MK with automotive PPAP documentation.
Recommandé
Embedded Web Server / IoT Edge Node
For an embedded web server serving HMI pages or REST/Modbus endpoints over Ethernet, the PIC32MX775F512L provides 512 KB Flash (enough for an HTTP server + lwIP + application logic) and 64 KB RAM (sufficient for 4-6 simultaneous TCP sockets). The Ethernet MAC paired with an RMII PHY enables 100 Mbps connectivity without external network processors. Combined with the USB-OTG port for local configuration and the dual CAN ports for fieldbus, the MCU serves as a single-chip IoT gateway. A typical design consumes ~150 mA at 3.3 V during full Ethernet activity with CPU at 80 MHz, allowing PoE Class 1 (4 W) operation.
Recommandé
POS Terminal / Payment Kiosk Controller
The PIC32MX775F512L-80V/PT suits POS terminals and self-service kiosks because it combines USB-OTG (for peripherals: barcode scanner, NFC reader, receipt printer), Ethernet (for payment processing and cloud sync), and the Parallel Master Port (for TFT/LCD display interface). 512 KB Flash hosts the application plus a TLS library for secure communications; 64 KB RAM supports display framebuffer slices. The 100-pin TQFP exposes sufficient I/O for keypad matrix, status LEDs, and a thermal printer UART. Wide-temperature operation supports indoor retail and outdoor kiosk deployments.
Recommandé
Building Automation Controller (BACnet/Modbus)
In a building automation controller (HVAC, lighting, access control), the PIC32MX775F512L-80V/PT provides dual CAN for BACnet MS/TP or KNX-style buses, plus Ethernet for IP-based BACnet/IP or Modbus TCP uplink to a building management system. The 100-pin TQFP drives local relays, triac interfaces, and analog sensor inputs through its 16-channel 10-bit ADC. 512 KB Flash holds the full BACnet stack plus application logic for HVAC scheduling and zone control. Operating from -40C to +105C supports unconditioned mechanical rooms and rooftop installations.
Recommandé
Medical Data Acquisition Front-End
For non-life-support medical instrumentation (patient monitors, lab analyzers, physiotherapy devices), the PIC32MX775F512L-80V/PT provides 16 channels of 10-bit ADC at 1 Msps for sensor signal acquisition, plus USB-OTG for tethered PC connectivity and Ethernet for networked lab integration. 512 KB Flash supports firmware DSP filters for ECG/EMG signal processing at modest sampling rates. The industrial temperature grade handles instrument-warming conditions in clinical environments. Note: this part does not carry IEC 60601 medical safety certification - designers must still implement required isolation and creepage/clearance per the equipment's target classification.

Notes de conception
Estimated: At 80 MHz, 3.3 V, full peripheral activity (Ethernet MAC + USB + dual CAN), core current consumption is approximately 80 mA plus ~25 mA for I/O toggling, totaling ~105 mA (0.35 W). Place a 10 µF bulk tantalum or ceramic capacitor near VDD pins 11, 28, 50, 56, 85 and a 100 nF ceramic on each VDD/VSS pair (six total: pins 10/11, 28/29, 50/51, 54/56, 85/86, 89/90). VDDCAP (pin 89) requires a 10 µF + 100 nF capacitor pair for the internal 1.8V regulator. Power-on ramp must be monotonic from 0V to 3.3V within Microchip-specified limits to avoid BOR (Brown-Out Reset) lockups.
The 100-pin TQFP (12x12 mm, 0.5 mm pitch) requires 4-layer PCB routing for the high-pin-count design. Use a dedicated ground plane on layer 2 and a 3.3V power plane on layer 3; route signals on outer layers. Ethernet MII/RMII traces to the external PHY must be length-matched within 50 mils for the data group and 100 mils for the clock to meet 100 Mbps timing. Keep USB DP/DM traces 90-ohm differential, length-matched within 2 mm, and routed over an unbroken ground plane. Crystal traces (OSC1/OSC2, pins 97/98) must be short, symmetric, and guarded by ground.
Common pitfalls: (1) Forgetting that the Ethernet MAC requires an external PHY - the PIC32MX775F512L does not include 10/100BASE-TX physical layer. (2) Configuring USB without the required 48 MHz clock accuracy (±0.25%) - the PLL must be tuned or an external 48 MHz oscillator used for USB compliance. (3) At 80 MHz from Flash, the prefetch cache module must be enabled with one wait state or code execution slows ~40%. (4) The MCLR pin (pin 18) is mandatory for reset - leaving it floating causes spurious resets; use a 10 kohm pull-up to VDD and a 100 nF capacitor for noise immunity.
Estimated: At 105 mA / 3.3 V (0.35 W) and TQFP-100 with theta_JA approximately 38 C/W on a 4-layer JEDEC test board, junction temperature rise is ~13C above ambient. At maximum +105C ambient the junction reaches ~118C, below the +125C maximum. For continuous operation at +105C, ensure at least 4 thermal vias under the exposed pad area (even though TQFP-100 does not have an exposed pad, the lead frame provides some thermal dissipation) and minimize switching I/O loading. For higher-power designs, migrate to the LQFP-100 or BGA-121 PIC32 variants which offer better thermal dissipation.
