MPN: PIC32MX675F256HT-80V/PT ✓ Hoạt độngPIC32MX675F256HT-80V/PT Tóm tắt
A 32-bit microcontroller (MCU) is a programmable processor built around a 32-bit data path, typically with on-chip Flash program memory, SRAM, peripherals, and interrupt controller. The PIC32MX series sits in the hierarchy: 32-bit MCU -> embedded processor -> MIPS M4K core -> Microchip PIC32 portfolio. Compared with 8-bit/16-bit MCUs, 32-bit parts provide higher throughput, larger address spaces, and richer peripherals for connected embedded designs.
Key features include 256 KB Flash, 64 KB RAM, USB-OTG (host/device/OTG), 10/100 Ethernet MAC with MII/RMII interface, two I2C, two SPI, two UART, five 16-bit timers, five input-capture and five output-compare modules, a 10-bit 1 Msps ADC with up to 16 channels, and a parallel master port (PMP). The 64-pin TQFP footprint exposes 53 general-purpose I/O pins, leaving several pins dedicated to oscillator, JTAG, and analog functions.
The M4K core executes most instructions in one cycle, providing 1.56 DMIPS/MHz and integer DSP extensions. The Ethernet MAC integrates an MII/RMII interface and the USB-OTG controller adds full-speed and low-speed USB with on-chip transceiver, removing the need for an external PHY for USB. DMA channels offload data movement between peripherals and memory, freeing the CPU for application code.
Typical applications include industrial Ethernet nodes, USB-OTG peripherals (HID, CDC, mass storage, audio), Ethernet-enabled PLCs, HVAC and building automation controllers, and graphical user interfaces using PMP to drive LCDs. Its combination of Ethernet, USB, and 80 MHz MIPS core suits connected industrial and consumer designs.
When designing with the PIC32MX675F256HT-80V/PT, ensure the 2.3-3.6V supply is decoupled with 100 nF + bulk ceramic placed near the VDD/VSS pairs. Configure the JTAG/ICSP pins (TMS, TCK, TDI, TDO) carefully so production programming is not blocked. Use the Ethernet MAC with an external PHY qualified for the target EMI environment.

Ứng dụng tiêu biểu
PIC32MX675F256HT-80V/PT phù hợp cho 7 Áp dụngs: Industrial Ethernet Node / PLC, USB-OTG Peripheral (HID / CDC / Audio), HVAC and Building Automation Controller, Graphical User Interface with PMP LCD, Connected Sensor Hub (IoT Gateway), Audio Streaming over USB or Ethernet, Test & Measurement Front-End with USB.
Industrial Ethernet Node / PLC
The PIC32MX675F256HT-80V/PT fits industrial Ethernet nodes because it integrates a 10/100 MAC with MII/RMII, 80 MHz MIPS32 M4K core, and 64 KB SRAM - enough headroom for lwIP or Microchip TCP/IP stacks alongside application code. Engineers pair it with an external PHY such as the LAN8720A or DP83848 and a 50 MHz oscillator to drive industrial protocols like Modbus TCP, EtherNet/IP, or PROFINET. The 105C temperature rating supports cabinet-mounted PLCs without active cooling.
Được đề xuất
USB-OTG Peripheral (HID / CDC / Audio)
The PIC32MX675F256HT-80V/PT suits USB-OTG peripherals because it integrates a USB-OTG controller with on-chip transceiver, eliminating an external ULPI chip and reducing BOM. With 80 MHz of CPU and 64 KB SRAM, it can run USB stacks plus class drivers for HID, CDC-ACM, or USB audio class 1.1 - useful for industrial input devices, configuration tools, or USB audio interfaces. Add a USB micro-B connector with ESD protection such as USBLC6-2SC6.
Được đề xuất
HVAC and Building Automation Controller
The PIC32MX675F256HT-80V/PT is well-suited for HVAC controllers because it provides 53 GPIO pins for triac/relay drives, keypads, and sensor inputs, plus 16 ADC channels for temperature and pressure monitoring. The 105C rating handles rooftop or boiler-room enclosures. Use a PMP interface to drive character or graphic LCDs for wall thermostats, and rely on the UART/I2C ports for external sensor and transceiver modules.
Được đề xuất
Graphical User Interface with PMP LCD
The PIC32MX675F256HT-80V/PT can drive graphical LCDs because the Parallel Master Port (PMP) interfaces to TFT panels and OLED modules up to 16-bit wide with DMA offload. Combined with 80 MHz of CPU, the part handles anti-aliased text and small widget refreshes without external graphics accelerators. Pair with a 3.5" QVGA TFT and an SPI touchscreen controller for a complete HMI module.
Được đề xuất
Connected Sensor Hub (IoT Gateway)
The PIC32MX675F256HT-80V/PT fits IoT gateways because it offers Ethernet or Wi-Fi IP, multiple UARTs for sensors, and a 10-bit ADC for analog channels - all from a single chip. With 64 KB SRAM it can buffer JSON payloads and TLS lite handshakes before forwarding over MQTT to the cloud. Add a sub-GHz radio via SPI for battery-backed remote sensor nodes.
Được đề xuất
Audio Streaming over USB or Ethernet
The PIC32MX675F256HT-80V/PT can act as a USB audio class 1.1 device or Ethernet-AV bridge because the DMA channels offload sample movement while the 80 MHz core runs the audio stack. With 64 KB SRAM it can buffer several ms of 48 kHz/16-bit stereo, and the 10-bit ADC can sample auxiliary analog inputs. Useful for intercoms, networked speakers, or USB audio adapters.
Được đề xuất
Test & Measurement Front-End with USB
The PIC32MX675F256HT-80V/PT fits USB-CDC-based test instruments because the 10-bit 1 Msps ADC samples waveforms while the USB-OTG port streams data to a PC. Engineers use the DMA to sustain sample rates above 500 ksps without CPU intervention. Combined with the 80 MHz core, the part supports on-the-fly FFT and decimation for compact bench tools.

Bảo phân biệt quan trọng
- Higher temperature ceiling (105C) for harsh industrial environments (vsPIC32MX675F256H-80V/PT)
- Integrated Ethernet MAC and USB-OTG in a single chip (vsPIC32MX460F512L-80V/PT)
- More RAM (64 KB) than 460F family (32 KB) (vsPIC32MX460F512L-80V/PT)
Ghi chú thiết kế
Place a 100 nF ceramic bypass capacitor directly next to each VDD pin and a bulk 10 uF tantalum or ceramic on the main 3.3V rail. The PIC32MX675F256HT-80V/PT has six VDD pins distributed across the 64-pin TQFP; pairing each one with local decoupling prevents supply droop during DMA and Ethernet bursts that could otherwise trip voltage monitors.
Route the Ethernet MII/RMII traces with 50-ohm controlled impedance and length-match the data/clock pairs within 50 mils. Place the external PHY integrated within 25 mm of the MAC pins to keep signal integrity intact, and provide a clean analog ground island for the PHY. JTAG TMS/TCK/TDI/TDO lines should be pulled up or routed with care so they do not block production programming.
Do not exceed the 3.6V absolute maximum on any I/O pin or the USB D+/D- pins, or the part will be damaged. Ensure the MCLR pin has a proper 10 kohm pull-up and a 100 nF cap to ground for noise immunity. The USB-OTG VBUS pin requires a 5V-tolerance circuit; do not feed 5V directly into a non-5V-tolerant GPIO. Verify oscillator loading capacitors against the chosen crystal ESR to avoid start-up failure at low temperatures.
Estimated: at 80 MHz CPU, 3.3V supply, typical industrial workloads (no Ethernet), ICC is approximately 70 mA so power dissipation is around 0.23 W. The TQFP-64 package has a theta_JA of approximately 35 C/W on a 4-layer JEDEC PCB, resulting in roughly 8C rise above ambient. At 105C ambient, this leaves 67C headroom - safe for the extended industrial grade.
Thông tin tuân thủ
