PIC32MX675F256L-80V/PF Présentation
A 32-bit microcontroller (MCU) is a microprocessor-on-a-chip that integrates a CPU core, Flash program memory, SRAM data memory, and a range of peripherals into a single package. The PIC32 architecture uses a MIPS32 M4K core with 5-stage pipeline, sitting in the hierarchy: microcontroller -> embedded MCU -> 32-bit MCU -> MIPS-based processor -> semiconductor IC. Compared with 8-bit or 16-bit MCUs, 32-bit devices like the PIC32MX675F256L execute instructions in fewer cycles, support larger memory spaces, and enable more sophisticated firmware stacks (TCP/IP, USB, graphics).
Key features of this variant include 256 KB on-chip Flash, 64 KB SRAM, USB-OTG full-speed peripheral, 10/100 Mbps Ethernet MAC with MII/RMII interface, a 16-channel 10-bit ADC with 1 Msps conversion rate, up to 53 general-purpose I/O, and two I2C, two SPI, and two UART interfaces. The -80V speed grade specifies 80 MHz maximum CPU clock, while the -V operating range covers -40C to +105C industrial temperatures. The 100-pin TQFP (PF) package provides ample I/O for graphics and parallel buses.
The device also includes a 4-channel DMA controller, five 16-bit timers/counters, an RTCC with calendar mode, JTAG and 2-wire ICSP debug interfaces, and a peripheral pin-select mechanism that maps digital functions to any remappable pin. The integrated Ethernet MAC and USB-OTG eliminate the need for external controllers in networked embedded designs.
Typical applications include industrial Ethernet gateways, USB-OTG enabled human-machine interfaces (HMI), networked sensors with web servers, building-automation controllers, and embedded point-of-sale terminals. Its 80 MHz performance and large SRAM also make it suitable for graphical LCD and small TFT control.
When designing with this part, pay attention to the brown-out-reset voltage selection (2.5 V to 3.6 V supply range), add a 10 uF bulk + 0.1 uF ceramic decoupling pair close to each VDD/VSS pin pair, and ensure the Ethernet PHY reference clock meets the MII/RMII timing requirements in the datasheet. Allocate dedicated PCB layers for the analog AV+/AV- supply pair to minimize ADC noise coupling.

Applications typiques
PIC32MX675F256L-80V/PF convient pour 6 applications: Industrial Ethernet Gateway, USB-OTG Human-Machine Interface, Networked Sensor with Web Server, Building Automation Controller, Embedded Point-of-Sale Terminal, Graphical LCD / Small TFT Controller.
Industrial Ethernet Gateway
The PIC32MX675F256L-80V/PF fits industrial Ethernet gateway designs because its integrated 10/100 MAC with MII/RMII eliminates external controllers and the 256 KB Flash/64 KB SRAM pair holds a TCP/IP stack (TCP, UDP, HTTP) plus an RTOS. At 80 MHz the M4K core sustains wire-speed HTTP request handling while leaving headroom for application firmware. The -40C to +105C grade supports factory cabinet environments. Connect a standard PHY to the MII/RMII pins, add a 25 MHz reference oscillator, and provide the 2.5 V to 3.6 V supply rail; the chip dissipates roughly 150 mW typical at 80 MHz so a small copper-pour heatsink is sufficient.
Recommandé
USB-OTG Human-Machine Interface
The PIC32MX675F256L-80V/PF suits USB-OTG HMI panels because it integrates both USB-OTG full-speed controller and 53 general-purpose I/O for driving keypads, LCDs, and indicator LEDs. The 80 MHz CPU executes USB HID class handlers and graphics refresh concurrently, while 64 KB SRAM accommodates USB descriptor buffers and frame buffers. The 100-pin TQFP package exposes enough pins for parallel RGB or SPI displays up to 3.5 inches. Add a USBLC6-2SC6 ESD array on D+/D-, a 12 MHz crystal with on-chip PLL configured to 80 MHz, and a 3.3 V LDO sized for the 250 mA peak USB enumeration current.
Recommandé
Networked Sensor with Web Server
The PIC32MX675F256L-80V/PF supports networked sensors with embedded web servers because the 256 KB Flash stores the Microchip Harmony TCP/IP stack (TCP, UDP, HTTP, SNMP) plus application code, and the 64 KB RAM holds socket buffers and Modbus registers. The integrated 10/100 MAC removes the need for an external controller, while the 10-bit ADC reads sensor inputs at up to 1 Msps for vibration or strain gauges. The -40C to +105C industrial temperature grade handles outdoor enclosures. Add a 25 MHz Ethernet PHY clock, 32.768 kHz crystal for the RTCC timestamp, and provision JTAG pads for in-field firmware updates.
Recommandé
Building Automation Controller
The PIC32MX675F256L-80V/PF enables building automation controller designs because it combines Ethernet, USB-OTG, and the 16-channel 10-bit ADC required for HVAC, lighting, and access-control I/O. The 80 MHz MIPS M4K core runs BACnet or Modbus TCP stacks alongside local control loops. With 53 GPIO the MCU can drive relay boards, dimmers, and 4-20 mA current-loop sensors directly. The 100-pin TQFP and -40C to +105C operation suit DIN-rail enclosures. Provide isolated RS-485 transceivers on UART lines, a 16 KB external SPI EEPROM for log storage, and adequate bulk capacitance for the 2.5 V to 3.6 V supply rail.
Recommandé
Embedded Point-of-Sale Terminal
The PIC32MX675F256L-80V/PF serves embedded POS terminal designs because USB-OTG supports barcode scanners and printers, Ethernet enables LAN payment processing, and the 53 I/O drive a 2-line-by-16-character customer display plus a thermal printer head. The 256 KB Flash stores a custom RTOS plus EMV/PCI firmware modules, while 64 KB RAM holds encryption buffers and transaction logs. At 80 MHz the MIPS M4K core achieves <100 ms card read latency. Connect an external MagTek or IDTech card reader over UART, a thermal printer stepper driver on GPIO, and an isolated Ethernet PHY for surge protection.
Recommandé
Graphical LCD / Small TFT Controller
The PIC32MX675F256L-80V/PF drives small TFT displays up to 3.5 inches because the 80 MHz MIPS M4K core refreshes QVGA framebuffers at 30 Hz and the 53 I/O exposes 8-bit PMP or SPI interfaces to common ILI9341 / ST7789 controllers. The 64 KB RAM holds a 320x240x16-bit double-buffer (153 KB) when supplemented with an external SPI SRAM. The integrated USB-OTG enables touch-screen firmware updates. Use a 20 MHz SPI clock for display refresh, an external 23LC1024 SPI SRAM for frame storage, and add a TPS65100 boost supply if the TFT requires +15 V and -10 V rails.

Notes de conception
Estimated: at 80 MHz with all peripherals enabled, core current is approximately 60 mA from VDD plus 20 mA on AVDD, for a total 3.3 V supply demand near 250 mW to 350 mW. Place a 10 uF tantalum or ceramic bulk capacitor plus a 0.1 uF ceramic decoupling capacitor on every VDD/VSS pair (typically 4 VDD pins on this 100-pin TQFP). Connect VBAT to a 3 V coin cell if RTCC timestamping is required across power cycles.
Route the 50 ohm USB D+/D- pair as a 90 ohm differential with matched length within 50 mil, and add a USBLC6-2SC6 ESD array as close to the USB connector as possible. Place the 25 MHz Ethernet reference crystal within 5 mm of the OSC1/OSC2 pins with a ground guard ring, and route RMII/MII traces as 50 ohm controlled impedance on the outer layer. Keep the AV+/AV- analog supply star-connected to a single ferrite bead off the digital 3.3 V rail to minimise ADC noise coupling.
Do not leave MCLR floating: add a 10 kohm pull-up to VDD and a 100 nF cap to ground for noise immunity. Configure the peripheral pin select (PPS) lock register before remapping digital peripherals to alternate I/O, otherwise PPS writes are silently ignored. Always read the device errata document for silicon revision A1 or A2 ADC reference issues before finalising firmware timing budgets.
