PIC32MX795F512L-80I/PT Présentation
A 32-bit microcontroller (MCU) is a programmable logic device that executes instructions from on-chip Flash memory, providing significantly higher throughput than 8-bit or 16-bit MCUs while integrating peripherals (timers, ADC, communication controllers) and memory on a single die. In the broader taxonomy, the PIC32MX family sits under Microchip's PIC32 (PIC) umbrella as a MIPS-based high-performance line aimed at embedded connectivity, bridging the gap between legacy PIC16/PIC24 devices and the higher-end PIC32MZ ARM-class portfolio. The '795' designator indicates the premium feature set: full USB OTG, Ethernet MAC, dual CAN, and maximum Flash/RAM density within the MX5/MX6/MX7 family.
Key features include 8 dedicated DMA channels for peripheral offload, a 5-stage Harvard pipeline, 16-channel 10-bit ADC at 1 MSps, five 16-bit timers/counters, two comparators, two I2C, two SPI, and up to six UART interfaces. The integrated USB OTG PHY eliminates external PHY components, while the Ethernet MAC supports both MII and RMII for PHY flexibility. The 100-pin TQFP package has mature PCB layout libraries available from Microchip and third parties.
Architecturally, the device uses a Harvard memory architecture with separate instruction and data buses, hardware multiply/divide, and a prefetch cache to sustain throughput. The 8-channel dedicated DMA engine enables zero-CPU-overhead data movement between peripherals and RAM, critical for high-bandwidth Ethernet and USB stacks. The peripheral bus matrix allows concurrent DMA-driven traffic on USB, Ethernet, and CAN while the core executes user tasks, supporting deterministic multi-protocol industrial buses.
Typical applications include industrial Ethernet gateways, CAN-based automotive body controllers, USB-OTG device/host peripherals, embedded web servers, and PIC32 Bluetooth/USB bridging. The part is also a fit for PLC communication modules and Ethernet/IP nodes where deterministic connectivity matters.
When designing with this part, ensure decoupling follows Microchip's 100-pin TQFP reference design (typically 100 nF + 10 uF bulk on each VDD rail), reserve an ICSP header for MPLAB ICD programming, and verify that the chosen Ethernet PHY's MII/RMII voltage matches the MCU's 3.3V I/O.

Notes de conception
Estimated: at 80 MHz with all peripherals active, the PIC32MX795F512L draws up to 100 mA from the 2.3-3.6V supply. Place a 10 uF bulk tantalum plus a 100 nF ceramic decoupling capacitor within 2 mm of each VDD/VSS pin pair. The USB PHY requires its own filtered 3.3V rail (USB VBUS-to-VUSB) when operating in host mode to limit digital-noise coupling.
The 100-pin TQFP package requires 4-layer PCB routing for signal integrity above 50 MHz core speeds. Keep RMII traces to the Ethernet PHY matched within 2 mm and length-matched within 0.5 cm. Place the 25 MHz main oscillator crystal within 5 mm of the OSC1/OSC2 pins with a guarded ground pour per Microchip 100-pin TQFP reference design guidelines.
Do not enable USB OTG host-mode VBUS drive before asserting appropriate overcurrent protection. The dual CAN controllers require 120 ohm termination resistors at the bus ends, not on the module. Always verify the JTAG/ICSP pinout matches the Microchip ICD programming header before fabout - the MCLR pin is a 5V-tolerant input that may need a 10 kohm pull-up for stable reset.
Estimated: at continuous 80 MHz core operation, the silicon junction-to-ambient thermal resistance is approximately 40 C/W in the 100-pin TQFP package. For ambient-temperature designs above 60C, ensure 1-2 square inches of copper pour beneath the exposed pad. No external heatsink is required in industrial -40C to +85C operation under normal load profiles per Microchip thermal models.
