PIC32MX695F512HT-80I/MR Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O on one silicon die. The PIC32MX family belongs to the MIPS32 architecture lineage, scaling up from 8/16-bit PIC microcontrollers to 32-bit performance while keeping the same MPLAB X toolchain, Harmony framework and peripheral library. Within Microchip's portfolio the MCU hierarchy runs: PIC32MX6xx/7xx -> PIC32MX family -> 32-bit MCU -> microcontroller -> semiconductor IC.
Key features include 128 KB of SRAM, 53 general-purpose I/O pins, a 10-bit 1 Msps ADC with up to 16 channels, five 16-bit timers/counters, an RTCC, and a JTAG/ICSP debug interface. The MR suffix denotes the 64-lead QFN package, the H-speed grade supports 80 MHz operation, the T suffix indicates tape-and-reel packaging, and the I temperature grade covers -40C to +85C industrial operation.
Typical applications include industrial Ethernet PLCs, building automation controllers, USB device/host peripherals, CAN-connected sensor nodes, point-of-sale terminals, and medical patient monitoring equipment that need deterministic real-time performance with rich wired connectivity. The dual CAN and Ethernet MAC enable industrial fieldbus gateway designs, while USB OTG supports portable data loggers. Comprehensive mains voltage design support comes from the integrated PHY interface and the DMA-driven Ethernet MAC, which offloads packet handling from the CPU.
When designing with this device, ensure that the 2.5V to 3.6V supply rail is decoupled with 100 nF ceramic capacitors within 5 mm of every VDDCORE/VSS pair, and that the Ethernet PHY-to-MAC RMII traces are length-matched within 50 mils to preserve signal integrity. The device requires a 3.3V supply for full-speed operation - voltages below 2.5V will not guarantee the 80 MHz performance. The "T" suffix in the MPN denotes tape-and-reel packaging; the non-T tray variant is PIC32MX695F512H-80I/MR.

Typical Applications
PIC32MX695F512HT-80I/MR is suitable for 7 applications: Industrial Ethernet PLC, USB Device/Host Data Logger, Building Automation Controller, Medical Patient Monitor, CAN-Connected Sensor Hub, Point-of-Sale Terminal, Industrial HMI Controller.
Industrial Ethernet PLC
The PIC32MX695F512HT-80I/MR's integrated 10/100 Ethernet MAC, dual CAN modules, and 512 KB Flash are well-matched to industrial Ethernet PLC designs that must run Modbus TCP or EtherNet/IP stacks while also handling CAN fieldbus traffic. Placed as the main controller with an external LAN8720A PHY, the MCU's 80 MHz MIPS core delivers deterministic interrupt latency, while the eight DMA channels offload packet buffering. The -40C to +85C industrial grade and 64-VQFN thermal pad support enclosed cabinet deployment, and the 53 GPIO pins accommodate digital I/O expansion for relay and sensor interfaces.
Recommended
USB Device/Host Data Logger
The PIC32MX695F512HT-80I/MR integrates USB 2.0 full-speed OTG, which suits portable USB data logger designs that need to connect to PCs or USB mass storage without an external bridge IC. With 512 KB Flash and 128 KB SRAM, the MCU can buffer multi-megabyte log runs before flushing to a USB stick via the integrated USB controller, while the 10-bit 1 Msps ADC captures analog sensor data. The 64-VQFN (MR) package keeps the board under 25 mm x 25 mm, ideal for handheld instruments; the 80 MHz core sustains real-time file system operations without dropping ADC samples.

Medical Patient Monitor
The PIC32MX695F512HT-80I/MR fits medical patient monitor designs that need deterministic real-time response for ECG, SpO2, and temperature acquisition while also streaming data over Ethernet to a central nurse station. Its 10-bit 1 Msps ADC captures ECG waveforms at 500 sps, the 80 MHz MIPS core handles QRS detection algorithms, and the integrated Ethernet MAC streams waveform data. The 512 KB Flash stores protocol stacks and waveform libraries, and the 64-VQFN package with exposed thermal pad supports fanless medical enclosure designs that must comply with IEC 60601-1 EMI margins.
Recommended
CAN-Connected Sensor Hub
The PIC32MX695F512HT-80I/MR's dual CAN modules suit automotive and industrial sensor hub designs that aggregate data from up to two CAN buses simultaneously. With 512 KB Flash, the MCU can run CANopen or J1939 stacks alongside application code; the 80 MHz MIPS M4K core handles scheduled message transmission with deterministic latency. The 64-VQFN MR package supports compact IP67-rated enclosures, and the -40C to +85C industrial range handles engine bay or outdoor cabinet deployment.

With 512 KB Flash and 128 KB SRAM, the MCU runs TLS libraries for PCI-compliant payment flows; the integrated USB OTG connects to printer/scanner peripherals without external hub ICs. The 64-VQFN MR package enables slim POS terminal form factors, and the 53 GPIO pins drive keypad matrix, LCD, and magnetic-stripe reader interfaces.
Recommended
Industrial HMI Controller
The PIC32MX695F512HT-80I/MR supports industrial HMI controllers that drive TFT LCD panels via PMP and connect to PLC backbones via Ethernet or CAN. Its parallel master port interfaces directly to TFT displays up to 16-bit wide; the 80 MHz core refreshes QVGA displays at 30 fps; and the integrated Ethernet MAC streams recipe data to MES servers. With 512 KB Flash and 128 KB SRAM, the MCU stores multiple language fonts and graphic assets; the 64-VQFN MR package with thermal pad handles continuous backlight driver thermal load.

Key Differentiators
- Integrated 10/100 Ethernet MAC plus dual CAN modules in a single die (vs PIC32MX575F512HT-80I/MR)

- Maximum Flash density in the PIC32MX6xx family in 64-VQFN (vs PIC32MX664F064H-I/MR)
Design Notes
Decouple every VDD pin with a 100 nF ceramic capacitor placed within 5 mm of the pin, plus a bulk 4.7 uF tantalum or ceramic capacitor on the main 3.3V rail. The PIC32MX695F512HT-80I/MR draws up to 70 mA at full 80 MHz operation with all peripherals active; an estimated quiescent current of 40 mA plus active peripheral current must be considered for LDO sizing. Use a 3.3V LDO rated at 250 mA minimum to maintain regulation under DMA and Ethernet bursts.
Connect the exposed thermal pad (pin 64) directly to the VSS plane with multiple thermal vias (4-9 vias in a 3x3 array, 0.3 mm drill) for optimal heat dissipation. The 9x9 mm VQFN MR package requires a continuous ground plane under the IC with no signal traces crossing the thermal pad landing area. RMII traces between the MCU and the external LAN8720A PHY should be length-matched within 50 mils to preserve Ethernet timing margins.
Do not omit the decoupling capacitors on the AVDD pins if the ADC is used - ADC accuracy depends on low-impedance analog supply. Configure the JTAG/TCK/TCK pins to alternate function only after debug sessions complete, since floating debug pins during reset can cause unintended boundary-scan entry. Ensure that the MCLR pin is pulled high through a 10 kohm resistor and never left floating, as floating MCLR causes intermittent reset events.
The 80 MHz core clock generates harmonics into the 240-480 MHz band; place the crystal within 5 mm of the OSC1/OSC2 pins and guard the traces with a ground pour to prevent radiated emissions. For RMII Ethernet, source-terminate the 50 MHz reference clock trace with 33 ohm series resistance at the MCU end to dampen reflections. The USB DP/DM traces should be 90 ohm differential with no stubs and length-matched within 150 mils.
Compliance Information
RoHS compliant per Microchip product page. Industrial -40C to +85C temperature grade, not AEC-Q100 qualified (use PIC32MX695F512HT-80V/MR for automotive grade).
