PIC32MX775F256LT-80I/BG Visão geral
A 32-bit microcontroller (MCU) is a programmable processor with on-chip Flash program storage, SRAM data memory, and integrated peripherals such as timers, ADC, communication controllers and DMA. Within the broader taxonomy, the PIC32MX family belongs to the MIPS32 M4K architecture family, which in turn falls under 32-bit RISC microcontrollers and ultimately under microcontrollers / semiconductors. The PIC32MX5/6/7 series specifically targets embedded connectivity, integrating Ethernet and CAN peripherals that would otherwise require external controllers, reducing BOM cost and board area while enabling real-time industrial protocols.
Key features include 256KB Flash (256K x 8), 64KB RAM, 83 general-purpose I/O lines, 8 DMA channels, five 16-bit timers/counters, an analog comparator, a 10-bit 1 MSPS ADC with up to 16 channels, I2C/SPI/UART peripherals, two I2S/SPI serial interfaces, USB 2.0 Full-Speed OTG, two CAN 2.0b modules, 10/100 Ethernet MAC with MII/RMII interfaces, and an RTCC. The 121-ball TFBGA package provides a compact 10x10 mm footprint at 0.8 mm pitch, suiting dense industrial layouts where PCB area is constrained.
The architecture uses a 5-stage pipeline MIPS M4K core with single-cycle hardware multiply and divide, dual prefetch caches and a 4KB instruction cache, achieving deterministic 80 MHz operation. Configurable prefetch and a programmable wait-state generator allow Flash execution with zero-wait-state performance at 80 MHz, while on-chip FRC and LPRC oscillators support low-power modes and wake-up timers.
Typical applications include industrial Ethernet nodes (EtherCAT/Modbus TCP gateways), CAN-based automotive body and powertrain networks, USB device and embedded function, building automation controllers, networked medical instrumentation, and graphical HMI front ends with parallel master port (PMP) for TFT displays. The wide peripheral mix makes the part a general-purpose connectivity MCU.
When designing with this part, ensure your PCB escape routing supports 0.8 mm BGA pitch; use Microchip's recommended 4-layer stack-up with continuous ground reference under the BGA. Plan for proper decoupling (0.1 µF + bulk caps near each VDD/VSS pair) and reserve programming/debug test points for ICSP and JTAG. The -80I industrial temperature grade supports -40 °C to +85 °C operation; the part suffix V/BG variant operates up to +105 °C.

Notas de projeto
The 121-ball TFBGA package uses 0.8 mm ball pitch which requires 4-layer PCB routing with microvia-in-pad or dogbone fanout. Use Microchip's recommended 0.4 mm escape traces, 0.2 mm via drill and 0.4 mm via pad. Place 0.1 µF X7R 0402 decoupling capacitors adjacent to each VDD/VSS ball pair, plus 4.7 µF bulk capacitors near each corner. Maintain a continuous ground reference under the BGA for SI and EMI performance per Microchip AN1255 PCB layout guidelines.
Do not omit the ICSP programming footprint on production PCBs - the PIC32MX775F256LT-80I/BG requires ICSP for firmware loading even if JTAG is present. Reserve at minimum PGECx/PGEDx test points plus MCLR pull-up to VDD via 10 kΩ. The 80 MHz prefetch cache must be enabled in the system configuration register before Flash execution at zero wait states; otherwise code runs at half speed per the PIC32MX5/6/7 family errata DS80000471H.
Estimated: at maximum core activity (80 MHz, all peripherals active, 3.6 V VDD) the PIC32MX775F256LT-80I/BG draws approximately 70-110 mA total. Power dissipation is approximately 250-400 mW; the 121-ball TFBGA package has thermal resistance θJA of approximately 30 C/W on 4-layer JEDEC EIA/JESD51 test board, yielding a self-heating rise of 8-12 C above ambient. For industrial -40 °C to +85 °C operation, ensure ambient + self-heating stays below the maximum 85 °C rating. Operational decoupling to minimum 2.3 V VDD and Sleep mode reduces idle power to approximately 50 µA per the family reference manual.
Route Ethernet MII/RMII signals with controlled impedance (50 Ω single-ended to ground reference) and length-matching per the MII/RMII specification. Use a series 33 Ω damping resistor on each MII output if signal integrity issues arise. Place the Ethernet PHY within 100 mm of the MCU with the clock trace length matched within 25 mm. For USB Full-Speed signals, maintain 90 Ω differential impedance on D+/D- per the USB 2.0 specification and place the USBLC6 ESD protection within 5 mm of the connector.
