PIC32MX695F512HT-80V/PT Overview
A microcontroller (MCU) is a single-chip computer integrating a CPU core, memory (Flash for code, SRAM for data), and programmable peripherals. The PIC32MX family is built on the MIPS32 M4K architecture, positioning it within the 32-bit MCU taxonomy: 32-bit microcontroller -> MIPS architecture -> PIC32 family -> PIC32MX5/6/7 connectivity sub-family. This hierarchy places the part squarely in the high-performance connectivity MCU tier used for embedded networking and USB.
Key features include 53 digital I/O pins, 8 DMA channels for low-CPU-overhead data movement, dual CAN 2.0b controllers, I2S audio interface, up to five 16-bit timers, four UARTs, two SPI, and two I2C ports. The integrated Ethernet MAC with MII/RMII interface and USB-OTG (host + device) enable direct connectivity without external PHY chips for USB-device-only designs. Hardware crypto and true random number generator (TRNG) blocks accelerate secure connected-node designs.
The architecture combines a 5-stage pipelined MIPS32 core with a dedicated peripheral bus, achieving 1.56 DMIPS/MHz while keeping interrupt latency deterministic. The 80 MHz maximum core clock with a 4-cycle multiply delivers ample headroom for TCP/IP stacks (TCP, UDP, HTTP) and SSL/TLS libraries. Microchip's MPLAB Harmony framework provides pre-validated TCP/IP, USB, and graphics libraries that port directly to this device.
Typical applications include industrial Ethernet nodes (Modbus TCP, EtherNet/IP gateways), USB human-interface devices, embedded web servers, HVAC controllers with BACnet/Modbus, point-of-sale terminals, and medical instrumentation requiring USB and Ethernet. The 80 MHz core and 128 KB SRAM are sufficient for lwIP + SSL stacks running TLS 1.2 handshakes.
When designing with this part, ensure that the 3.3 V rail is decoupled with at least one 10 uF bulk plus 0.1 uF ceramic per power pin pair. For USB-OTG host operation, provide a 5 V boost supply; the VBUS pin must sense VBUS voltage. The 'V' temperature grade suffix denotes -40C to +105C operation, suitable for industrial environments.

Typical Applications
PIC32MX695F512HT-80V/PT is suitable for 6 applications: Industrial Ethernet Gateway / Modbus TCP Node, USB-OTG Human Interface / Data Acquisition Device, Embedded Web Server / IoT Edge Node, HVAC / Building Automation Controller, Medical Instrumentation / Diagnostic Device, Point-of-Sale Terminal / Embedded Payment Device.
Industrial Ethernet Gateway / Modbus TCP Node
The PIC32MX695F512HT-80V/PT is a strong fit for industrial Ethernet gateways because its integrated 10/100 Mbit MAC with MII/RMII allows direct connection to a Micrel KSZ8041 or Microchip LAN8720A PHY without an external MAC bridge, saving BOM cost and PCB area. The 128 KB SRAM holds lwIP + Modbus TCP stacks plus 8 DMA channels move Ethernet packets in/out without CPU intervention. At 80 MHz the M4K core delivers enough headroom to run TCP/IP, TLS 1.2, and an application layer (Modbus TCP, EtherNet/IP, BACnet) simultaneously. The dual CAN 2.0b controllers let the same firmware bridge CANopen/DeviceNet on the field side to Ethernet on the plant side, a common industrial topology. Operating temperature of -40C to +105C (V grade) supports cabinet and outdoor installations.
Recommended
USB-OTG Human Interface / Data Acquisition Device
The PIC32MX695F512HT-80V/PT's USB 2.0 Full-Speed OTG controller with on-chip transceiver supports both USB device (e.g., HID, CDC, vendor-class data acquisition) and USB host (e.g., mass storage, HID dongles) roles without an external ULPI chip. The 16-channel 10-bit ADC at 1 Msps combined with 8 DMA channels captures multi-channel sensor data while USB enumerates and streams to a host PC at up to 12 Mbit/s. The 512 KB Flash holds full USB stacks and composite-device class drivers from Microchip's MLA, and 128 KB SRAM accommodates multi-packet USB buffers plus application data. VBUS sensing and 5 V boost support simplify USB-host designs that need to power external devices from the board.
Recommended
Embedded Web Server / IoT Edge Node
The PIC32MX695F512HT-80V/PT functions well as an embedded web server thanks to its 80 MHz MIPS core, 128 KB SRAM, and 512 KB Flash, which together host the Microchip Harmony TCP/IP stack (HTTP server, SNTP, MQTT) plus an HTML/CSS user interface in Flash. The integrated Ethernet MAC with RMII interface keeps the BOM small for space-constrained IoT edge nodes. The 53 GPIO pins accommodate SPI sensors, I2C peripherals, UART modems, and PWM actuators commonly found in IoT nodes. The V temperature grade (-40C to +105C) supports outdoor enclosures and factory-floor installations.
Recommended
HVAC / Building Automation Controller
The PIC32MX695F512HT-80V/PT is well-matched to HVAC and building automation controllers because it combines Ethernet (BACnet/IP, Modbus TCP), dual CAN (BACnet MS-TP, CANopen), multiple UARTs (RS-485 Modbus RTU), and 5x 16-bit timers (PWM for fan/valve control) on one die. The 80 MHz core and 128 KB SRAM handle PID loops plus networking protocols in a single firmware image. The 10-bit ADC at 1 Msps reads multiple temperature, pressure, and flow sensors in real time. The V grade -40C to +105C rating supports mechanical rooms and rooftop installations.
Recommended
Medical Instrumentation / Diagnostic Device
The PIC32MX695F512HT-80V/PT's combination of USB device (for PC connectivity), Ethernet (for hospital network integration), 16-channel 10-bit ADC (for sensor readout), and 128 KB SRAM (for sample buffering) suits medical instrumentation such as blood-pressure monitors, pulse oximeters, and portable diagnostic devices. The 80 MHz MIPS core runs signal-processing algorithms (filtering, FFT) alongside USB CDC communication to host software. The 53 GPIO interface with the on-chip 10-bit ADC at 1 Msps captures analog front-end signals with low latency. Note that medical designs typically require IEC 60601 compliance at the system level - this MCU is a candidate component but requires full system-level qualification.
Recommended
Point-of-Sale Terminal / Embedded Payment Device
The PIC32MX695F512HT-80V/PT is a candidate MCU for point-of-sale terminals because it integrates USB device (for PC tethered mode), Ethernet (for IP-based payment terminals), dual CAN (for cash drawer / peripheral bus), 4 UARTs (for mag-stripe readers, printers, PIN pads), and 2 SPI/I2C (for secure crypto modules). The 128 KB SRAM and 512 KB Flash hold TLS libraries, EMVCo kernels, and application firmware. The hardware crypto accelerator and true random number generator support PCI PTS payment-terminal security requirements at the hardware level, though full PCI PTS certification requires system-level design effort.

Design Notes
Estimated: At 80 MHz CPU clock with all peripherals enabled (Ethernet MAC, USB, both CAN controllers, all UARTs/SPI/I2C active), the PIC32MX695F512HT-80V/PT draws approximately 70 mA from the 3.3 V supply, equating to about 230 mW of core power. Provide a 3.3 V LDO rated for at least 250 mA, and place one 10 uF bulk tantalum or ceramic plus a 0.1 uF ceramic bypass within 5 mm of each VDD pin pair (pins 5/12, 21, 5 V tolerant pins are grouped). For USB-OTG host mode, an additional 5 V boost supply capable of 500 mA must be provided because VBUS is sensed but not sourced by the MCU. A power-on reset supervisor is not strictly required (the internal POR handles VDD rise), but an external voltage supervisor (such as MCP1316) on MCLR is recommended for brown-out-sensitive industrial designs.
For 64-pin TQFP-64 footprint layout, allocate a continuous ground plane on the top or second layer and tie all VSS pins (4, 11, 20, 26, 64) to it with multiple vias for thermal dissipation (the part dissipates ~230 mW and does not require a thermal pad). Keep the 50 MHz Ethernet RMII traces between the MCU and the LAN8720A PHY within 25 mm and length-matched to within 2 mm; route them on the layer adjacent to a continuous ground plane. Place the 25 MHz Ethernet reference clock trace away from switching signals. For USB, route the D+/D- pair as a 90 ohm differential pair and keep the total length under 50 mm to meet USB 2.0 Full-Speed signal integrity. Decouple AVDD (pin 27) with a dedicated 10 uH ferrite bead from VDD plus 0.1 uF + 10 uF ceramic caps to AVSS for low-noise ADC performance.
A common design pitfall is misconfiguring the PIC32MX695F512HT-80V/PT's oscillator at 80 MHz - the part requires the internal 8 MHz FRC multiplied by PLL to reach 80 MHz, and an external 8 MHz crystal or oscillator must be selected carefully to match the PLL input range (4-10 MHz). Bypassing this and feeding a 20 MHz crystal directly will not produce 80 MHz core clock. Another pitfall: the dual CAN controllers and the Ethernet MAC both require DMA channels - mis-allocating DMA can starve USB or ADC of DMA bandwidth, especially in mixed-protocol designs. Finally, the 'T' suffix in the part number denotes tape-and-reel packaging, while 'H' denotes tray; for prototype builds use the tray variant because tape-and-reel small quantities are often cut-tape and may not include the full reel leader. Verify the order code with the Microchip ordering reference guide before placing production orders.
