PIC32MX695F512H-80I/PT Descripción general
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, and a rich set of peripherals (timers, ADCs, communication interfaces, GPIO) into one IC. The PIC32MX695 sits within the hierarchy: MCU -> 32-bit MCU -> MIPS-based MCU -> PIC32 family -> PIC32MX5/6/7 sub-family -> connected-MCU segment. Connected MCUs combine deterministic real-time control with on-chip wired networking, eliminating the need for an external network processor.
Key differentiating specifications include 80 MHz core clock delivering 105 DMIPS, hardware USB 2.0 OTG with integrated PHY (eliminating external transceiver cost), full 10/100 Ethernet MAC with MII/RMII, dedicated DMA channels for USB and Ethernet, and 53 user I/O pins with 5V-tolerant inputs on select pins. The 2.3V to 3.6V operating range and industrial -40C to +85C temperature grade make it suitable for industrial control and harsh embedded environments.
The device uses a Harvard architecture with separate instruction and data buses and a 5-stage pipeline, supporting MIPS16e code compression for up to 40% smaller code footprint. On-chip peripherals include a 16-bit parallel master port for external bus expansion, multiple UART/SPI/I2C controllers, a 16-channel 10-bit ADC, and five 16-bit timers plus two 32-bit timers.
Typical applications include industrial Ethernet gateways, USB device controllers, embedded web servers, building-automation controllers, point-of-sale terminals, and networked sensor hubs. The integrated USB+ENET combination uniquely targets connected-device designs where discrete USB or Ethernet implementation would otherwise require a companion network IC.
When designing with this MCU, ensure USB PHY external components (precision reference resistor and ESD protection) follow the USB 2.0 specification; for Ethernet, provide a 25 MHz reference clock for MII or 50 MHz for RMII. Use the PIC32 64-pin USB/Ethernet starter kit and MPLAB Harmony framework as reference designs for firmware structure and middleware integration.

Notas de diseño
Decoupling the PIC32MX695F512H-80I/PT requires at least one 100 nF ceramic capacitor within 3.1 mm of each VDD pin (pins 2, 17, 44) and a bulk 10 uF tantalum or ceramic capacitor at the board-level supply entry. Per Microchip datasheet section 'Electrical Characteristics', each VDD/VSS pair must be decoupled individually. Place a ferrite bead on analog AVDD (pin 16/49) supply if analog peripherals are active, to suppress digital switching noise from corrupting ADC readings.
The PIC32MX695F512H-80I/PT requires a precision 12.4 kohm reference resistor on the VUSB3V3 pin to bias the internal USB PHY. Per the Microchip datasheet, omitting this resistor or using the wrong value (typically +/- 1%) causes USB enumeration failures or non-compliance with USB 2.0 signaling eye pattern. Also ensure the VBUS sense pin (RF3) is connected to VBUS through a divider for proper OTG voltage detection. For Ethernet, do not forget the 25 MHz MII reference clock or 50 MHz RMII reference clock.
The 64-pin TQFP package has 0.5 mm pitch, requiring fine-pitch PCB layout. Per IPC-2221, use 0.15 mm trace/space with 0.25 mm via lands. Keep USB DP/DM traces (RF4/RF5) at 90 ohm differential impedance and length-matched within 1.5 mm, with a ground reference plane on layer 2. Ethernet MII/RMII traces should be length-matched within 2.5 mm and routed over a continuous ground plane to maintain signal integrity per IEEE 802.3.
At 80 MHz full activity, the PIC32MX695F512H-80I/PT typically dissipates under 100 mW, well within the 64-pin TQFP thermal envelope (theta_JA approximately 50 C/W on a 4-layer JEDEC test board). No external heatsink is required for typical industrial applications. However, for high-IO-toggle designs with all 53 I/O pins driving 10 mA loads, package self-heating can reach 10C above ambient; verify with a thermal probe in worst-case firmware states.
