MPN: PIC32MX775F512HT-80V/PT ✓ AktifPIC32MX775F512HT-80V/PT Ringkasan
A 32-bit MCU (microcontroller unit) is an integrated circuit containing a processor core, program memory (Flash), data memory (SRAM), and a rich mix of peripherals (USB, CAN, Ethernet, ADC, timers, GPIO). Compared with 8- or 16-bit MCUs, 32-bit parts execute instructions on wider registers, allowing faster arithmetic and more deterministic handling of communication stacks. The PIC32MX5/6/7 family specifically targets connected applications by integrating high-bandwidth peripherals (USB-OTG, Ethernet, dual CAN) that previously required an external MCU plus dedicated controller ICs.
Key features include 512KB Flash organized as 512K x 8, 64KB SRAM, 51 usable I/O pins, four-wire SPI, I2C, dual CAN 2.0b, USB-OTG, 10/100 Mbps Ethernet MAC, 16-channel 10-bit ADC at 1 Msps, a 16-bit parallel master port, and a 4-channel DMA. The part operates from 2.3V to 3.6V, supports industrial temperature range (-40C to +105C), and is pin-compatible with most PIC24/dsPIC DSC devices in the same package footprint.
The MIPS32 M4K core provides single-cycle multiplication, hardware divide, and a five-stage pipeline, delivering 1.56 DMIPS/MHz. Multiple power management modes (idle, sleep, deep sleep) and the Fail-Safe Clock Monitor reduce dynamic and standby power. Interrupt latency is deterministic and individually programmable in priority, which simplifies real-time fieldbus handling.
Typical applications include industrial Ethernet gateways, CAN-based automotive body controllers, USB-OTG medical peripherals, building-automation controllers, and connected sensors in IoT edge nodes. The combination of Ethernet MAC, dual CAN, and USB-OTG in a single MCU removes the need for external interface bridges and shortens BOM cost.
When designing with this part, plan the clock tree carefully - the 80MHz SYSCLK requires an 8MHz primary oscillator with on-chip PLL. Decouple VDDCORE pins with 1uF and 0.1uF ceramics close to the package and keep the analog AVdd rail separate to preserve ADC SNR.

Aplikasi Umum
PIC32MX775F512HT-80V/PT cocok untuk 6 aplikasis: Industrial Ethernet Gateway, CAN-Based Automotive Body Controller, USB-OTG Medical Peripheral, Building Automation Controller, Connected IoT Edge Sensor Node, Industrial HMI Touch Panel.
Industrial Ethernet Gateway
The PIC32MX775F512HT-80V/PT's integrated 10/100 Mbps Ethernet MAC and 80MHz MIPS32 M4K core make it ideal for industrial Ethernet gateways such as Modbus TCP and EtherNet/IP slave nodes. Placed between the fieldbus side (RS485 transceiver) and the network side (Ethernet PHY + RJ45), the MCU runs a TCP/IP stack in parallel with a real-time OS without external bridge ICs. Its 512KB Flash accommodates the full Microchip Harmony TCP/IP stack plus application logic, while the 4-channel DMA offloads Ethernet packet copies to keep CPU utilization below 60 percent. The 2.3V-3.6V industrial voltage range and -40C to +105C operating temperature support 24V factory-floor environments.

CAN-Based Automotive Body Controller
With dual CAN 2.0b controllers and 16-channel 10-bit ADC, the PIC32MX775F512HT-80V/PT fits CAN-based body controllers managing door modules, lighting clusters, or seat controllers. Each CAN channel drives a separate bus (for example, body CAN and chassis CAN), while the ADC samples battery voltage, lighting feedback, and temperature sensors at up to 1 Msps. The 64KB SRAM buffers complete CAN frames before forwarding to the gateway ECU. The part's industrial temperature grade (-40C to +105C) is sufficient for cabin-mounted ECUs; pair with an external CAN transceiver such as MCP2551 or TJA1050 for the physical layer.

USB-OTG Medical Peripheral
The PIC32MX775F512HT-80V/PT's USB 2.0 Full-Speed OTG controller supports both device and host roles on a single port, ideal for medical peripherals such as patient monitors, infusion pumps, or portable diagnostics. In device mode, the MCU streams patient data over USB CDC or vendor-class to a host PC; in host mode, it enumerates a USB flash drive for log export. The 51 GPIOs interface with LCDs, keypads, and sensor front-ends. The 10-bit ADC digitizes analog sensor channels at 1 Msps with adequate resolution for physiological-signal conditioning pre-filters.

Building Automation Controller
Building-automation controllers for HVAC, lighting, and access-control subsystems benefit from the PIC32MX775F512HT-80V/PT's mix of dual CAN, Ethernet, and USB-OTG on a single MCU. The Ethernet MAC links the controller to the building's BACnet/IP or Modbus TCP backbone, while dual CAN runs the field-level MS/TP device bus for distributed I/O. The 512KB Flash holds the BACnet stack plus graphical HMI logic, and the 16-bit PMP drives character or TFT LCDs. Industrial temperature grade permits unheated equipment-room installations.

Connected IoT Edge Sensor Node
For IoT edge nodes aggregating sensor data and pushing to a cloud gateway, the PIC32MX775F512HT-80V/PT integrates Ethernet and USB-OTG for both wired IP and cellular-modem attachment. The 4-channel DMA moves ADC samples into memory without CPU intervention, leaving the 80MHz MIPS core free for stack processing, JSON formatting, and TLS handshake acceleration. The 51 I/Os interface with multiple sensor buses (I2C, SPI, UART), and the 12KB boot Flash supports secure OTA firmware updates.
Direkomendasikan
Industrial HMI Touch Panel
The PIC32MX775F512HT-80V/PT supports industrial HMI touch panels through its 16-bit Parallel Master Port (PMP) for direct interface to TFT LCDs and resistive-touch controllers. The 80MHz core drives QVGA panels at 30 fps while running Modbus or EtherNet/IP. The 64KB SRAM holds double-buffered framebuffers, and the 4-channel DMA accelerates screen updates. The 51 GPIOs multiplex LED backlight, keypad, and rotary encoder inputs alongside the PMP data bus.

Catatan Desain
Decouple VDDCORE pins (one or more per package) with a 1uF X7R ceramic plus a parallel 0.1uF X7R ceramic placed within 3 mm of the pins. Keep the AVDD rail sourced through a ferrite bead from VDD, with its own 10uF + 0.1uF pair, to keep ADC noise below 1 LSB. ENVREG (pin 64) must be tied to VDD; do not leave it floating or the internal 1.8V regulator will not start.
Route the 80MHz SYSCLK source (8MHz crystal + PLL) on the shortest possible trace between the crystal load capacitors (typically 18 pF for 8 MHz fundamental) and pins 47-48. Place the EZCN crystal within 5 mm of the package and guard the traces with a ground pour. The Ethernet RMII traces to the LAN8742A PHY must be length-matched within 2 mm and routed over an unbroken ground plane to meet 100 Mbps signal-integrity margins.
At 80 MHz the PIC32MX775F512HT-80V/PT draws approximately 90 mA from VDD (3.3V), so steady-state dissipation is about 300 mW. The 64-pin TQFP theta_JA is around 50 C/W, so junction temperature rise is roughly 15 C above ambient at room temperature. Industrial-grade operation up to +105 C ambient is feasible without a heatsink, but above +85 C ambient consider routing additional copper pour on VDD/VSS planes.
Do not connect JTAG pins TMS/TCK/TDI/TDO to external pull-ups or pull-downs unless absolutely required; the on-chip pull-ups are enabled by default. The MCLR pin (54) requires a 10 kohm pull-up to VDD and a 100 nF cap to ground for in-circuit Serial Programming (ICSP). Forgetting the MCLR pull-up causes intermittent reset failures during programming.
USB-OTG differential pair (DP/DM) requires 90 ohm differential impedance and equal-length traces; place the 15 kohm pull-down on D+ for full-speed device mode. For host mode add a 15 kohm pull-up on D+ or D- (full/low speed detection). EMC compliance: place ferrite beads on VDD and AVDD near the MCU when designing for industrial EN 55022 Class B emissions.
