MPN: PIC32MX775F512HT-80I/MR ✓ פעילPIC32MX775F512HT-80I/MR סקירה
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, and a rich set of peripherals into one package. Within the broader taxonomy, the PIC32MX775 sits under 32-bit MCU -> RISC MCU -> microcontroller -> integrated circuit -> semiconductor. Compared with 8-bit and 16-bit MCUs, a 32-bit MCU executes instructions on 32-bit data paths, allowing larger address spaces, higher throughput, and richer peripheral integration for connected embedded applications.
Key features of the PIC32MX775F512HT-80I/MR include 80 MHz core speed, 512 KB Flash, 64 KB SRAM, integrated USB 2.0 Full-Speed device/host/OTG, two CAN 2.0b controllers, a 10/100 Mbit Ethernet MAC, 8-channel DMA, and 5 timers / 5 IC/OC / 5 I2C / 4 UART / 2 SPI peripherals. The 64-VQFN (9x9 mm) package exposes 53 digital I/O pins and supports industrial operating temperatures from -40C to +85C.
The device uses the MIPS32 M4K core with 5-stage pipeline and prefetch cache, executing most instructions in a single clock cycle. The dual Flash panel and live update partition allow firmware field updates via bootloader, while 8 DMA channels offload data movement between peripherals and RAM. USB, CAN, and Ethernet MACs share DMA, reducing CPU interrupt load in connected designs.
Typical applications include industrial Ethernet nodes, CAN-connected motor and building automation controllers, USB peripherals and embedded hosts, factory automation gateways, and connected medical or instrumentation devices. The PIC32MX5/6/7 series is fully supported by MPLAB Harmony and MPLAB X IDE for firmware development.
When designing, ensure the USB D+/D- trace impedance is 90 ohms differential and add a 1 uF bulk capacitor near the VBUS pin. Use the internal pull-up on D+ only in bus-powered designs; for self-powered devices, drive D+ through an external switchable resistor to avoid back-powering the host port.

יישומים טיפוסיים
PIC32MX775F512HT-80I/MR מתאים עבור 6 יישוםs: Industrial Ethernet Gateway, USB-Connected Embedded Peripherals, CAN Bus Industrial Nodes, Building Automation Controllers, Connected Medical Instrumentation, Multi-Protocol Sensor Hubs.
Industrial Ethernet Gateway
The PIC32MX775F512HT-80I/MR's integrated 10/100 Mbit Ethernet MAC and 80 MHz MIPS32 M4K core make it well suited for industrial Ethernet gateways that must run a lightweight TCP/IP stack (e.g., TCP/IP + MQTT or Modbus TCP) alongside application logic. Placed on the fieldbus side of a factory node, it bridges Ethernet to local CAN and UART sensors while the 8-channel DMA engine offloads packet movement from the CPU. The 64 KB SRAM comfortably holds a TCP/IP socket buffer plus application queues, and the 512 KB Flash is large enough for the Harmony 3 Net Preset plus user firmware without external program memory.
מומלץ
USB-Connected Embedded Peripherals
The PIC32MX775F512HT-80I/MR's USB 2.0 Full-Speed device/host/OTG controller, combined with 53 digital I/O pins and 64 KB SRAM, supports USB HID/CDC/MSC peripherals such as data loggers, human-interface panels, and instrument front-ends. A typical design places the MCU between a host PC and downstream UART/I2C/SPI sensors, presenting as a composite USB device. The 80 MHz core provides enough headroom for USB stack plus real-time sampling, and the 512 KB Flash lets Harmony 3 USB stacks fit alongside application firmware without an external boot-loader partition.
מומלץ
CAN Bus Industrial Nodes
With two independent CAN 2.0b controllers and a 80 MHz core, the PIC32MX775F512HT-80I/MR is well matched to industrial CAN nodes such as motor controllers, building-automation sensors, and automotive-bus gateways. Each CAN controller has its own DMA channel, so traffic on one bus does not block the other. The 53 I/O pins expose ample PWM/IC/OC channels for motor-drive interface, and the 64 KB SRAM holds CAN message queues without dropping frames under burst conditions.
מומלץ
Building Automation Controllers
The PIC32MX775F512HT-80I/MR's mix of Ethernet, dual CAN, USB, and 53 I/O pins serves BACnet/Modbus building-automation controllers that bridge multiple field buses. The 80 MHz M4K core handles BACnet/IP plus local control loops, while 64 KB SRAM maintains HVAC schedule tables and trend logs. Operating temperature -40 C to +85 C and the 64-VQFN (9x9) exposed-pad package make it thermally robust inside equipment rooms without requiring a heatsink above 0.5 W dissipation.
מומלץ
Connected Medical Instrumentation
The PIC32MX775F512HT-80I/MR provides 16-channel 10-bit ADC, USB, and ample I/O for connected medical instruments such as portable monitors and bench-top analyzers. The 80 MHz core runs USB CDC plus signal-processing loops, while 512 KB Flash holds firmware for waveform capture and on-screen UI. The 64-VQFN package's small footprint fits inside handheld enclosures, and the industrial -40 C to +85 C range supports hospital and field-clinic environments. Note: medical certification is system-level; this MCU itself is not FDA-cleared.
מומלץ
Multi-Protocol Sensor Hubs
The PIC32MX775F512HT-80I/MR aggregates UART, I2C, CAN, and SPI sensors into a single Ethernet or USB gateway. Five I2C buses support multiple sensor ICs without bus contention, while four UARTs bridge RS-485/Modbus devices. The 8-channel DMA engine handles simultaneous data streams without CPU interrupt load, and 64 KB SRAM buffers pre-aggregation payloads. The 64-VQFN 9x9 mm exposed-pad package allows compact PCB designs where the MCU sits at the heart of the sensor hub.

הערות תכנון
The 64-VQFN (9x9 mm) package has an exposed thermal pad on pin 64. The PCB land pattern MUST include a central pad with at least 9 thermal vias (0.3 mm drill, 0.6 mm pitch) tied to the ground plane. Without this thermal path, the junction temperature can exceed 125 C at full 80 MHz operation with all peripherals active. Solder paste stencil should use a 0.127 mm (5 mil) thickness with a 1:1 aperture ratio for the central thermal pad to avoid voids above 25 percent.
USB D+/D- traces must be routed as a 90 ohm differential pair with no splits or test points in the middle of the run. Add a common-mode choke near the connector and place the 15 kohm pull-down on D+ and D- to ensure a defined high-speed idle state. For self-powered USB designs, drive D+ through a switchable pull-up (e.g., VBUS-detect GPIO) instead of the internal pull-up to avoid back-powering the host port when the device is unpowered.
Place a 1 uF + 0.1 uF bulk-decoupling pair on every VDD/VSS pin combination, with the 0.1 uF as close as physically possible to the IC pin (under 1 mm trace length). The analog AVdd/AVss pins must be filtered with a ferrite bead and a 10 uF + 0.1 uF pair, and the AGND pin should return to a clean analog ground island that joins the digital ground at a single point near the PCB power entry.
Supply voltage range is 2.3 V to 3.6 V. The PIC32MX775F512HT-80I/MR consumes roughly 70 mA at 80 MHz with all peripherals active, so the 3.3 V LDO must supply at least 100 mA plus margin for digital I/O sourcing. For USB bus-powered designs, ensure VBUS detection GPIO is wired before the regulator enable so the MCU can hold the USB PHY in high-Z until a valid VBUS is present.
