PIC32MX695F512H-80I/MR Visão geral
A microcontroller (MCU) is an integrated circuit that combines a CPU core, program memory (Flash), data memory (RAM), and a rich set of peripherals (UART, SPI, I2C, USB, timers, ADC, GPIO) on a single silicon die. The PIC32 family uses the MIPS32 M4K core with 5-stage pipeline and Harvard architecture, supporting MIPS16e mode for up to 40% smaller code, positioning PIC32MX as a mid-range 32-bit MCU family within the broader semiconductor hierarchy of microcontroller -> 32-bit MCU -> embedded processor.
Key features include an integrated USB 2.0 Full-Speed On-The-Go (OTG) peripheral with on-chip PHY, a 10/100 Ethernet MAC with MII/RMII interface, 8 DMA channels (4 dedicated to USB/ENET), 53 general-purpose I/O pins, two I2C ports, two UART ports, two SPI ports, a CAN module, and a 16-channel 10-bit ADC. The device operates from 2.5V to 3.6V supply.
The architecture delivers 105 DMIPS at 80 MHz with a 5-stage pipeline, 32-bit MIPS M4K core and MIPS16e code compression. Dedicated DMA channels offload Ethernet and USB traffic from the CPU, enabling high-throughput connected applications without saturating core cycles.
Typical applications include industrial Ethernet gateways, USB-enabled embedded devices, CAN-connected automotive ECUs, IoT edge nodes with TCP/IP stacks, and graphical HMI controllers with parallel master port. The integrated USB OTG PHY and 10/100 Ethernet MAC make it suited for connected-node designs that previously required an external PHY or communications controller.
Design consideration: ensure the bottom exposed pad (EP) of the 64-VQFN is soldered to a continuous VSS copper plane for thermal dissipation; missing the EP connection can raise junction temperature by 15-20C under full USB + Ethernet load.

Aplicações típicas
PIC32MX695F512H-80I/MR é adequado para 6 aplicaçãos: Industrial Ethernet Gateway, USB Device and Host Application, CAN-Based Automotive ECU, IoT Edge Sensor Node, Graphical HMI Controller, Connected Medical Monitoring Device.
Industrial Ethernet Gateway
The PIC32MX695F512H-80I/MR's integrated 10/100 Ethernet MAC with MII/RMII interface eliminates the need for an external Ethernet controller, enabling compact industrial gateways. With 8 DMA channels (4 dedicated to Ethernet and USB), TCP/IP packet transfer occurs without CPU intervention, freeing the M4K core for protocol conversion tasks like Modbus TCP to Modbus RTU bridging. The 512 KB Flash accommodates full TCP/IP stacks such as Microchip MLA or Harmony, while 128 KB RAM handles socket buffers and packet queues. Industrial -40C to +85C operation covers factory-floor deployment without additional thermal management. The 53 GPIO pins support multiple serial ports for legacy fieldbus integration alongside Ethernet connectivity.
Recomendado
USB Device and Host Application
The PIC32MX695F512H-80I/MR integrates a USB 2.0 Full-Speed On-The-Go (OTG) controller with on-chip PHY, removing the cost and PCB area of an external USB transceiver. This enables USB device, host, or dual-role OTG applications including USB-to-UART bridges, USB mass-storage readers, USB HID controllers, and USB device chargers. The 4 dedicated DMA channels for USB offload packet transfer at 12 Mbps full-speed, while the 80 MHz M4K core handles application logic. With 128 KB RAM, USB descriptors, HID report buffers, and CDC class state machines all fit in RAM. The 16-channel 10-bit ADC supports battery monitoring in USB charger applications where input voltage must be measured to control charging current.
Recomendado
CAN-Based Automotive ECU
The PIC32MX695F512H-80I/MR's integrated CAN 2.0B module with 1 Mbps bit rate makes it suitable for non-safety-critical automotive body and comfort ECUs such as seat controllers, mirror adjusters, lighting modules, and HVAC blend-door actuators. The 80 MHz core runs 105 DMIPS, sufficient for CANopen or J1939 protocol stacks with 128 KB RAM for receive buffers and 512 KB Flash for protocol libraries. Operating from -40C to +85C covers cabin environments. The 53 GPIO handle multiple motor-driver PWM channels, position-feedback ADCs, and LIN/UART slaves. Designers targeting AEC-Q100 qualified parts should evaluate the automotive-graded PIC32MX variants; the standard -80I/MR is industrial-grade and not AEC-Q100 certified.
Recomendado
IoT Edge Sensor Node
The PIC32MX695F512H-80I/MR's combination of Ethernet MAC, USB OTG, CAN, and dual UART/SPI/I2C peripherals enables IoT edge nodes that aggregate data from multiple sensor buses and forward it to a cloud gateway. The 16-channel 10-bit ADC reads analog sensors directly, while the 53 GPIO handle digital interrupts and PWM actuator control. 512 KB Flash runs MQTT-SN, CoAP, or lightweight TLS libraries. 128 KB RAM accommodates TLS session keys and message queues. The 2.5V-3.6V supply range supports battery-powered designs with switching regulators. The industrial -40C to +85C range covers outdoor enclosure deployments in shade and direct sun when properly derated.
Recomendado
Graphical HMI Controller
The PIC32MX695F512H-80I/MR's Parallel Master Port (PMP) interfaces directly to graphical LCDs and TFT displays up to QVGA resolution without an external graphics controller. With 80 MHz core speed and 128 KB RAM, the MCU can drive small monochrome or color TFT panels while running keypad scan, menu logic, and communication tasks. The 512 KB Flash stores fonts, bitmaps, and multi-language strings. The 53 GPIO handle keypad scanning, LED indicators, and rotary encoder inputs. The 16-channel 10-bit ADC reads backlight brightness and ambient light sensors for adaptive display dimming. The dual UART/SPI/I2C peripherals connect to wireless modules like Wi-Fi or Bluetooth for cloud-connected HMIs.
Recomendado
Connected Medical Monitoring Device
The PIC32MX695F512H-80I/MR is suited for connected medical monitoring peripherals such as pulse oximeters, blood pressure cuffs, and digital thermometers that transmit data to a host PC or mobile gateway. The USB device capability connects to a host computer with CDC ACM class for virtual COM port data streaming, while the integrated Ethernet MAC enables wired connectivity for bedside monitors. The 16-channel 10-bit ADC captures analog sensor signals from optical pulse sensors or pressure transducers with 4.88 mV LSB at 3.3V VREF. The 128 KB RAM buffers waveform data before USB transmission. The -40C to +85C range covers clinical and home environments. Medical IEC 60601 compliance is the system integrator's responsibility.

Principais diferenciais
- Higher RAM capacity in same 64-VQFN footprint (vs PIC32MX675F512H-80I/MR)
- Integrated USB OTG PHY (vs PIC32MX470F512H-I/MR)
- Integrated 10/100 Ethernet MAC (vs PIC32MX470F512H-I/MR)
Notas de projeto
Estimated: the 64-VQFN (MR) 9x9 mm package bottom exposed pad (EP) MUST be soldered to a continuous VSS copper plane of at least 1 square inch to meet the -40C to +85C industrial temperature spec under full USB + Ethernet load. The datasheet's theta_JA of approximately 28 C/W assumes the EP is properly soldered. Missing the EP connection can raise junction temperature by 15-20C and may cause thermal shutdown during sustained USB OTG host operation.
Place all VDD pins (8, 27, 44) and VSS pins (7, 28, 45, 60) with 100 nF decoupling capacitors within 3 mm of each pin. Use a 4.7 uF bulk capacitor near the package. Route the 80 MHz crystal traces (OSC1 pin 61, OSC2 pin 62) symmetrically with short stubs and guard them with a ground plane. For MII/RMII Ethernet routing, keep traces under 50 mm and use 50 ohm controlled impedance. Place the optional Ethernet PHY clock within 25 mm of the MCU's ERCLK pin.
Do not confuse the 64-VQFN (MR) footprint with the 64-TQFP (PT) footprint; they are pin-compatible electrically but require different PCB land patterns. Ensure the bootloader and configuration bits are set to use the internal 8 MHz RC oscillator with PLL to reach 80 MHz before USB or Ethernet enumeration. Watchdog timer must be enabled in production firmware and reset periodically; without WDT, a single code lockup can permanently stall the connected device. The MCLR pin (63) requires a 10 kohm pull-up to VDD.
