PIC32MX795F512LT-80I/TL Présentation
A microcontroller unit (MCU) is a self-contained computer on a single chip that combines a processor core, program memory, data memory, and configurable peripherals. The PIC32MX795F512L sits in the 32-bit MCU class, above 8-bit and 16-bit devices, and below application processors such as the Cortex-A family. Within the Microchip PIC32MX5/6/7 series, it is the connectivity flagship, adding Ethernet MAC and dual CAN to the MIPS32 M4K pipeline.
Key differentiators include the integrated 10/100 Ethernet MAC with dedicated DMA, USB 2.0 full-speed OTG with an on-chip transceiver, dual CAN 2.0B modules, and 16-channel 10-bit ADC sampling at 1 Msps. The 512 KB Flash and 128 KB SRAM support RTOS-based applications and TCP/IP stacks without external memory.
The M4K core uses a 5-stage pipeline with a single-cycle 32x16 MAC, delivering 1.56 DMIPS/MHz. The peripheral pin select (PPS) feature remaps digital I/O to reduce PCB routing constraints, while the 8-channel DMA controller offloads data movement from the CPU.
Typical applications include industrial Ethernet gateways, CAN-to-Ethernet protocol bridges, motor control with field-oriented control, USB device/host instrumentation, and building automation controllers. The 2.3 V to 3.6 V operating range and -40C to +85C industrial temperature grade suit factory-floor environments.
When designing with this device, place the 0.1 uF decoupling capacitors within 5 mm of each VDD pin and keep the Ethernet differential pairs at 100 ohm impedance. The VTLA package requires a reflow profile matched to its exposed pad for reliable thermal and electrical grounding.

Applications typiques
PIC32MX795F512LT-80I/TL convient pour 6 applications: Industrial Ethernet Gateway, CAN-to-Ethernet Protocol Bridge, Motor Control with Field-Oriented Control, USB Device and Host Instrumentation, Building Automation Controller, Data Acquisition and Signal Processing.
Industrial Ethernet Gateway
The PIC32MX795F512LT-80I/TL fits industrial Ethernet gateways because its integrated 10/100 Mbit MAC with dedicated DMA handles packet traffic without CPU intervention, while 512 KB Flash and 128 KB SRAM accommodate a full TCP/IP stack and Modbus TCP server. The 80 MHz M4K core at 1.56 DMIPS/MHz processes protocol translation between Ethernet and serial fieldbus links. In a typical design, the MAC connects to an external PHY through the RMII interface, and the dual CAN controllers bridge to CANopen devices. The trade-off versus a Cortex-M7 gateway is lower raw throughput, but the on-chip Ethernet MAC eliminates an external controller and reduces BOM cost.
Recommandé
CAN-to-Ethernet Protocol Bridge
The PIC32MX795F512LT-80I/TL is ideal for CAN-to-Ethernet bridges because it integrates two CAN 2.0B controllers alongside the 10/100 Ethernet MAC, allowing simultaneous dual-bus CAN traffic and Ethernet uplink on one chip. The 8-channel DMA moves CAN and Ethernet frames without CPU load, and 128 KB SRAM buffers burst traffic during protocol conversion. In a bridge design, one CAN module connects to a vehicle bus and the other to a machine bus, while the Ethernet MAC forwards aggregated data to a supervisory system. The 2.3 V to 3.6 V supply and -40C to +85C rating suit factory-floor and automotive-adjacent environments.
Recommandé
Motor Control with Field-Oriented Control
The PIC32MX795F512LT-80I/TL supports motor control applications through its 16-channel 10-bit ADC sampling at 1 Msps, which captures three-phase current feedback for field-oriented control loops. The 80 MHz M4K core with single-cycle 32x16 MAC executes Park and Clarke transforms in real time, while the five 16-bit timers generate complementary PWM with dead-time insertion. In a typical servo drive, the ADC samples shunt currents synchronized to PWM, and the DMA transfers results to RAM without CPU overhead. The trade-off versus a dedicated motor-control MCU is the absence of on-chip op-amps, but the integrated Ethernet enables remote drive monitoring.
Recommandé
USB Device and Host Instrumentation
The PIC32MX795F512LT-80I/TL suits USB instrumentation because it integrates a USB 2.0 full-speed OTG controller with an on-chip transceiver, eliminating an external USB PHY. The 512 KB Flash stores firmware and data-logging buffers, while 128 KB SRAM supports USB endpoints and a command parser. In a data-acquisition instrument, the device enumerates as a CDC or HID device and streams ADC samples to a host PC. The 16-channel 10-bit ADC and 8-channel DMA allow continuous sampling without CPU intervention. The trade-off versus a dedicated USB MCU is higher power, but the integrated Ethernet and CAN add connectivity options.
Recommandé
Building Automation Controller
The PIC32MX795F512LT-80I/TL fits building automation controllers because it combines Ethernet, dual CAN, and six UART channels for BACnet/IP, CANopen, and Modbus RTU connectivity on a single chip. The 512 KB Flash holds a building management stack, and 128 KB SRAM buffers sensor and actuator data across multiple buses. In a typical HVAC controller, the Ethernet MAC connects to the building backbone while UARTs interface to zone sensors and CAN links to VAV boxes. The -40C to +85C industrial temperature range and 2.3 V to 3.6 V supply support reliable operation in mechanical rooms. The trade-off is higher cost than an 8-bit controller, justified by integrated networking.
Recommandé
Data Acquisition and Signal Processing
The PIC32MX795F512LT-80I/TL supports data acquisition because its 16-channel 10-bit ADC samples at 1 Msps and the 8-channel DMA streams results to SRAM without CPU intervention, enabling continuous multi-channel logging. The 80 MHz M4K core with single-cycle MAC executes FIR and IIR filters in real time, and 512 KB Flash stores calibration tables and firmware. In a typical DAQ node, the ADC digitizes sensor signals, DMA transfers blocks to RAM, and the core applies filtering before transmitting over Ethernet or USB. The trade-off versus a dedicated DSP is lower MIPS, but the integrated connectivity and memory reduce system cost.

Notes de conception
Decouple every VDD pin with a 0.1 uF ceramic capacitor placed within 5 mm of the pin, plus a 10 uF bulk capacitor near the package. The PIC32MX795F512LT-80I/TL draws transient current during 80 MHz operation; inadequate decoupling causes clock jitter and Ethernet packet errors. Use a solid ground plane under the device and connect the exposed pad to ground with multiple vias.
Route the Ethernet RMII signals (ETXD0/1, ERXD0/1, EREFCLK) as 50 ohm controlled-impedance traces and keep them matched in length within 5 mm. Place the external PHY within 25 mm of the MCU to minimize skew. Keep the USB D+/D- pair at 90 ohm differential impedance and avoid stubs. The 124-pin VTLA exposed pad must be soldered with adequate via stitching for thermal relief.
Do not exceed the 3.6 V maximum supply voltage; the PIC32MX795F512LT-80I/TL is not 5 V tolerant on all pins. Verify the VREF+ and VREF- connections for the ADC, as floating references cause inaccurate conversions. Ensure the MCLR pin has a 10 kohm pull-up and 0.1 uF capacitor to prevent spurious resets. Confirm the oscillator circuit matches the datasheet's recommended load capacitors for the selected crystal.
