PIC32MX695F512LT-80I/TL Overview
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (flash), data memory (RAM), and programmable peripherals designed to be embedded inside a larger electronic system. Within the system hierarchy, PIC32MX sits between 8/16-bit PIC16/PIC24 MCUs and 32-bit Cortex-M devices, offering a balance of deterministic real-time performance, generous peripheral integration, and free MPLAB® Harmony firmware support for TCP/IP, USB, and graphics stacks.
Key features include a five-stage pipelined Harvard architecture with MIPS16e® mode (up to 40% smaller code), 16 channels of 10-bit ADC at 1 Msps, five 16-bit timers, two I²C, two SPI, and two UART/USART interfaces, plus 83 general-purpose I/O pins. The device runs from 2.3 V to 3.6 V with an industrial -40 °C to +85 °C operating range, making it suited to connected industrial and consumer systems.
Typical applications include Ethernet-connected industrial sensors, USB HID/CDC peripherals, building-automation gateways, networked home appliances, and embedded web-server designs. The combined USB-OTG + Ethernet MAC, four DMA channels, and 512 KB flash allow a single chip to host both the protocol stack and the application layer without an external PHY companion.
When designing with this part, plan oscillator- and PLL-mode settings carefully: the 80 MHz core requires an 8 MHz or 10 MHz primary oscillator multiplied by the internal PLL, and any Ethernet RMII link needs a 50 MHz reference. The 9x9 VTLA lands demand a PCB footprint with tightly controlled thermal vias to keep the junction within the 125 °C maximum.

Typical Applications
PIC32MX695F512LT-80I/TL is suitable for 6 applications: Ethernet-Connected Industrial Sensors, USB HID / CDC Peripherals, Building-Automation Gateways, Embedded Web-Server Designs, Networked Home Appliances, Industrial Data-Acquisition Modules.
Ethernet-Connected Industrial Sensors
The PIC32MX695F512LT-80I/TL integrates a 10/100 Ethernet MAC with MII/RMII and four dedicated DMA channels, enabling a single-chip Modbus TCP / EtherNet/IP / PROFINET node for industrial sensor aggregation without an external PHY companion. The 80 MHz MIPS32 M4K core delivers 105 DMIPS, comfortably running the free Microchip Harmony TCP/IP stack plus application-level data processing at 1 kHz sample rates. The 16-channel 10-bit ADC handles up to 16 analog sensor inputs at 1 Msps aggregate, while 512 KB flash and 128 KB RAM host both stack and user code. Designers should use an RMII-equipped 50 MHz reference oscillator to keep the BOM minimal.
Recommended
USB HID / CDC Peripherals
The PIC32MX695F512LT-80I/TL's integrated USB 2.0 On-The-Go controller with on-chip PHY makes it a strong fit for USB Human Interface Device and Communication Device Class peripherals - HID keyboards, mice, game controllers, CDC virtual COM ports, and custom vendor-class instruments. The USB PHY removes the need for an external ULPI transceiver, shrinking PCB area and BOM cost. Four dedicated DMA channels offload USB packet movement, freeing the 80 MHz core to handle device-class drivers and host-side command processing. Industrial temperature range (-40 to +85 °C) and 3.3 V operation suit both consumer and industrial USB accessories.
Recommended
Building-Automation Gateways
Building-automation gateways benefit from the PIC32MX695F512LT-80I/TL's combined Ethernet MAC + USB OTG + 16-channel ADC in a single chip. The Ethernet MAC uplinks to a BACnet/IP or Modbus TCP building network while the USB OTG port serves as a service / commissioning interface. The 83 GPIO pins and two UART interfaces connect to multiple downstream field buses (RS-485 sensors, I²C peripherals, SPI displays), and the 128 KB RAM hosts BACnet objects for typical small-to-medium buildings. MPLAB® Harmony provides reference BACnet/IP stacks to shorten firmware development.
Recommended
Embedded Web-Server Designs
The PIC32MX695F512LT-80I/TL is well-suited to embedded web-server designs (configuration portals, diagnostic dashboards, simple REST APIs) where the Ethernet MAC, 80 MHz CPU, 512 KB flash, and 128 KB RAM can host an lwIP or Microchip Harmony TCP/IP stack plus a small HTTP server. The four DMA channels keep TCP/IP packet movement off the CPU, while 16 channels of 10-bit ADC expose sensor data via JSON endpoints. Industrial temperature range allows deployment in unheated equipment closets. The VTLA 9x9 mm footprint is small enough for DIN-rail-mountable gateways.
Recommended
Networked Home Appliances
Smart washing machines, refrigerators, and HVAC controllers benefit from the PIC32MX695F512LT-80I/TL's USB-OTG service interface plus Ethernet MAC for cloud connectivity, paired with 16-channel ADC for temperature / pressure / flow sensing. The 83 GPIO pins handle motor-control signals, relay drivers, and user-interface buttons / LEDs. The 512 KB flash stores the Wi-Fi/Ethernet protocol stack plus appliance-specific firmware, while 128 KB RAM supports HTTP and MQTT client buffers. Industrial -40 to +85 °C operation survives compressor-closet deployments.
Recommended
Industrial Data-Acquisition Modules
The PIC32MX695F512LT-80I/TL's 16-channel 10-bit ADC at 1 Msps aggregate sampling rate supports multi-channel industrial data acquisition modules (vibration monitoring, process control, energy metering). The Ethernet MAC streams samples to a host PC or PLC over Modbus TCP / EtherNet/IP, while the USB OTG port serves as a local service interface for firmware updates. 512 KB flash stores calibration tables and protocol stack, and 128 KB RAM serves as a circular sample buffer. The five 16-bit timers capture PWM inputs from flow meters or quadrature encoders alongside the ADC scan.

Design Notes
The 124-VTLA (9x9 mm) land-grid-array package requires a PCB footprint with non-solder-mask-defined (NSMD) lands, a 0.4 mm pitch, and an array of thermal vias under the center pad to the internal ground plane. Per IPC-7351, the via diameter should be 0.25 mm with 0.5 mm pitch and the center pad should have a 0.2 mm larger stencil aperture than the land. This maximizes thermal conduction and minimizes solder voiding during reflow. Estimated: assuming a 0.5 W dissipation at 80 MHz and 2.3-3.6 V supply, the 9x9 VTLA with thermal vias achieves a junction-to-ambient thermal resistance (θJA) in the 25-30 °C/W range - adequate for industrial deployments without external heatsinking.
The PIC32MX695F512LT-80I/TL requires a dedicated 3.3 V rail capable of delivering 100 mA peak with <50 mV ripple for proper USB OTG PHY operation. According to the Microchip datasheet section on power considerations, place a 10 µF tantalum or ceramic bulk capacitor plus three 0.1 µF ceramic capacitors within 5 mm of the VDDCORE pins to suppress switching transients during peripheral DMA bursts. A ferrite bead between the USB 3.3 V supply and the digital 3.3 V rail is recommended to isolate USB PHY noise from the ADC analog reference.
A common mistake is configuring the Ethernet MAC in MII mode without supplying a 25 MHz reference clock - MII requires a 25 MHz PHY-side clock, while RMII requires a 50 MHz reference. The 80 MHz core cannot be derived from the same oscillator; an external 8 MHz or 10 MHz crystal multiplied by the PLL yields the 80 MHz SYSCLK. Estimated: if the RMII 50 MHz reference and the 8 MHz primary oscillator share the same ground via path, Ethernet packet errors can occur from ground bounce - separate analog and digital ground returns under the chip.
