PIC32MX695F512H-80V/MR - 80MHz 32-bit MCU USB-OTG Ethernet 512KB | Microchip
MPN: PIC32MX695F512H-80V/MR ✓ Hoạt độngPIC32MX695F512H-80V/MR Tóm tắt
A 32-bit microcontroller (MCU) is a microprocessor core with on-chip Flash, RAM, and peripherals designed for embedded control. The PIC32 family sits at the high end of Microchip's MCU portfolio, with an architecture borrowed from MIPS and a peripheral set aimed at connected, industrial, and graphical embedded applications. Within the PIC32 hierarchy, PIC32MX is the mainstream line; the 5xx/6xx/7xx subfamily adds integrated connectivity (USB, Ethernet, CAN), positioning it above the 1xx/2xx/3xx/4xx/5xx general-purpose parts and below the PIC32MZ higher-performance family.
Differentiating specifications for the PIC32MX695F512H-80V/MR include: 16-bit parallel master port, 4 dedicated DMA channels for USB-OTG and Ethernet, 5 UART, 4 SPI, 5 I2C, and 2 CAN interfaces, plus a CTMU for touch and a PMP for graphics or external memory. The -80V speed grade runs up to 80 MHz; the V suffix denotes the -40C to +105C industrial operating range.
Typical applications include industrial Ethernet nodes, USB-OTG device/host controllers, CAN-based automotive subsystems, and HMI/gateway products. The integrated 10-bit ADC and rich serial peripheral mix reduce external component count for sensor hubs and protocol bridges. Design considerations include thermal management of the 9x9 mm QFN exposed pad, careful power-rail sequencing (2.3-3.6V core), and trace-length matching for the Ethernet MII/RMII signals. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes not found in the standalone manufacturer datasheet.

Ứng dụng tiêu biểu
PIC32MX695F512H-80V/MR phù hợp cho 6 Áp dụngs: Industrial Ethernet Sensor Node, USB-OTG Data Logger / Industrial Dongle, CAN-Based Automotive Body Controller, HMI / Graphical Gateway with Parallel Master Port, Wireless Gateway with Wi-Fi/BLE SPI Radio, Embedded Web-Server / SCADA Node.
Industrial Ethernet Sensor Node
The PIC32MX695F512H-80V/MR is well matched to industrial Ethernet sensor nodes because it integrates a 10/100 Ethernet MAC with MII/RMII interfaces, 128 KB of RAM for a full TCP/IP stack (e.g., Microchip Harmony Net), and 4 dedicated DMA channels that offload packet handling from the 80 MHz MIPS32 M4K core. The -40C to +105C operating range (V grade) supports factory-floor enclosures without active cooling. Designers place the MAC's MII lines to the RJ-45 magnetics with controlled-impedance 50 ohm traces and connect the integrated USB-OTG to a diagnostic port for firmware updates. The 512 KB Flash accommodates OTA bootloaders plus application code. Trade-off: 64-pin QFN limits I/O to 53 GPIO, so choose PIC32MX795 (100-pin TQFP) if you need more parallel I/O.

USB-OTG Data Logger / Industrial Dongle
The PIC32MX695F512H-80V/MR's integrated USB 2.0 OTG controller with PHY (no external PHY needed) makes it a strong fit for USB host, device, and dual-role dongles used as data loggers or field-service tools. The 80 MHz core and 4 DMA channels sustain USB Full-Speed throughput (12 Mbps) without CPU stall, while 128 KB RAM buffers bursts of data from sensors connected over UART/SPI/I2C. Use the CTMU for temperature measurement and the 10-bit ADC for analog inputs. Design note: USB DP/DM traces must be 90 ohm differential and routed within 2 mm of each other; place the ESD protection array near the connector. The 64-pin QFN 9x9 mm exposed pad must be soldered to a continuous ground plane for thermal dissipation.

CAN-Based Automotive Body Controller
The PIC32MX695F512H-80V/MR integrates 2 CAN 2.0b controllers alongside Ethernet and USB-OTG, which suits body and chassis control modules that bridge CAN-FD vehicle networks to off-board Ethernet diagnostic or telematics links. The 512 KB Flash holds CAN stack plus J1939/CANopen libraries, and the 80 MHz/105 DMIPS core processes multiple CAN frames per millisecond while running an Ethernet TCP/IP stack concurrently. The 5 UART channels interface to legacy RS-485 / RS-232 sensors. The V-grade temperature option supports under-dash and engine-bay periphery placements. Design note: add a CAN transceiver such as the MCP2561 between the MCU CAN pins and the bus, plus a common-mode choke for EMI robustness.

HMI / Graphical Gateway with Parallel Master Port
The PIC32MX695F512H-80V/MR integrates a Parallel Master Port (PMP) that interfaces to external SRAM, NOR Flash, or graphic LCD controllers without a CPLD, simplifying HMI gateway designs that bridge Ethernet to a local display. The 128 KB RAM is shared between TCP/IP buffers and frame buffer slices for a small TFT. The 5 UART, 4 SPI, and 5 I2C mix allows multi-protocol sensor aggregation. Use the 10-bit ADC for backlight current sensing. Trade-off: 53 GPIO in 64-pin QFN constrains simultaneous TFT data + Ethernet + USB; if more I/O is required, step up to the PIC32MX795F512L in TQFP-100.

Wireless Gateway with Wi-Fi/BLE SPI Radio
Pair the PIC32MX695F512H-80V/MR with an SPI-attached Wi-Fi or BLE module (e.g., MRF24WG0MA or ATWINC1500) to build a wireless IoT gateway that bridges cloud Ethernet to local sensor radios. The 4 dedicated DMA channels and 80 MHz MIPS core manage SPI radio traffic plus a TCP/IP cloud connection concurrently. USB-OTG enables a fallback tethered connection during commissioning. The 10-bit ADC monitors battery voltage on battery-backed gateways. Design note: SPI lines to the radio must be length-matched and routed over a continuous reference plane; isolate the radio antenna keep-out from the MCU's switching Vdd plane.

Embedded Web-Server / SCADA Node
The PIC32MX695F512H-80V/MR's 128 KB RAM and 512 KB Flash comfortably host an HTTP server plus a real-time control loop for SCADA nodes and remote telemetry units. The integrated 10/100 Ethernet MAC eliminates external MAC chips; 4 dedicated DMA channels ensure low-latency TCP frame handling. With 5 UART, 4 SPI, 5 I2C, and 2 CAN, the MCU aggregates field-sensor traffic from Modbus, SPI peripherals, and CAN J1939 buses. The -40C to +105C industrial temperature (V grade) supports outdoor enclosures. Design note: enable the hardware crypto engine and use MPLAB Harmony's TCP/IP stack with mbedTLS for secure remote management.

Ghi chú thiết kế
The 64-pin VQFN (9x9 mm) exposes a thermal pad (EPAD) on the underside that must be soldered to a continuous ground plane on the top layer with thermal vias to inner ground planes. Without EPAD soldering, junction-to-ambient thermal resistance (theta_JA) rises dramatically and the device may throttle or fail at sustained 80 MHz / full-peripheral loads. Use an array of 4x4 thermal vias (0.3 mm drill, 0.6 mm pitch) under the pad. Estimated: at 80 MHz with full USB + Ethernet + 2 CAN active, expect ~150 mA core current; PDISSIPATION = 3.3 V x 0.15 A = 0.495 W, well within the VQFN-64 ~30 C/W theta_JA when EPAD is properly soldered.
Place decoupling capacitors (100 nF X7R 0402) as close as possible to every Vdd/Vss pair. Add one 10 uF X5R bulk cap near the main Vdd pin and one 10 uF on the Vbus pin if USB device mode is used. Route the 80 MHz crystal traces symmetrically within 5 mm of the MCU with a continuous ground reference plane beneath; the two crystal traces should be matched within 1 mm. Ethernet MII/RMII signals to the PHY must be 50 ohm controlled-impedance and length-matched within 50 mil; keep these away from switching DC-DC nodes.
Three common pitfalls: (1) Do not exceed 3.6 V on any I/O; the PIC32MX6xx is NOT 5 V tolerant. Use level shifters for legacy 5 V peripherals. (2) The PGECx/PGEDx ICSP pins must be accessible for in-circuit programming; do not strap them permanently. (3) USB DP/DM traces must be 90 ohm differential with matched length; failing to do so causes USB compliance failures and intermittent enumeration. (4) The 2.3 V minimum Vdd must be observed; brown-out below this causes Flash corruption if write protection is not enabled in the DEVCFG fuse.
Keep high-speed signals (USB DP/DM, Ethernet MII/RMII, SPI to radio) on the top layer over a continuous ground plane on layer 2; do not route signals over power-plane splits. The 80 MHz main oscillator traces must be guarded by ground traces to prevent crosstalk into adjacent ADC inputs. Place the 10-bit ADC inputs (ANx) away from switching regulators and digital clocks; add a small RC filter (100 ohm + 100 nF) at the ADC pin to reduce digital switching noise coupling.
