PIC32MX695F512HT-80V/MR Présentation
A 32-bit microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, and configurable peripherals around one bus matrix. Within the broader taxonomy, PIC32MX devices sit under MIPS-based RISC microcontrollers, which in turn are a subclass of microcontrollers within the embedded processor semiconductor family. The M4K core implements the MIPS32 instruction set with DSP extensions, giving PIC32MX parts a 5-stage pipeline and hardware multiply/divide suitable for digital signal processing at 80 MHz. Compared with 8-bit/16-bit MCUs, the PIC32MX695 family addresses designs that need TCP/IP stacks, USB stacks, or graphical user interfaces without offloading to an external controller.
Key features include 512 KB Flash / 128 KB SRAM (substantially larger than typical 8-bit MCUs), 53 digital I/O pins, four 16-bit timers, five input-capture and five output-compare/PWM modules, a parallel master port, and a real-time clock with calendar. The integrated Ethernet MAC and USB-OTG controllers allow single-chip networked and bus-powered designs, removing the need for an external PHY-less companion. The 10-bit ADC supports up to 16 channels with automatic channel scanning.
Typical applications include industrial Ethernet gateways, USB device or host peripherals, automotive telematics nodes, and consumer products that require CAN, USB, and Ethernet connectivity in a single footprint. The "V" temperature grade (-40C to +105C) makes the part acceptable for outdoor enclosures and under-hood adjacent zones, while the 9x9 mm QFN keeps the design compact. MPLAB Harmony and MPLAB X IDE provide the supported firmware toolchain with TCP/IP, USB, and graphics libraries.
When designing with this part, observe the 2.5V-3.6V supply range (3.3V typical), provide adequate bulk decoupling near the VDD/VSS pins, and connect the exposed pad to a solid ground plane for thermal and electrical performance. Use the integrated DMA channels to offload peripheral-to-memory transfers and free CPU cycles for application code. The Ethernet MAC requires an external PHY (such as a Microchip KSZ8041) and a 50 ohm magnetics-isolated RJ45.

Industrial Ethernet Gateway
The PIC32MX695F512HT-80V/MR's integrated 10/100 Mbit Ethernet MAC and 512 KB Flash make it ideal for industrial gateways that bridge Modbus/TCP or EtherNet/IP fieldbus to higher-level SCADA systems. The 80 MHz MIPS32 M4K core runs Microchip's free TCP/IP stack (TCP, UDP, DHCP, DNS, HTTP, FTP, SMTP, TFTP, SNMP) with headroom for application code, and 128 KB SRAM holds multiple concurrent socket buffers. An external Microchip KSZ8041 PHY plus magnetics-isolated RJ45 completes the link; the MCU provides RMII-style interface timing per the family datasheet. The 105C V grade allows operation inside unventilated control cabinets.
Recommandé
USB Device/Host Peripheral
The PIC32MX695F512HT-80V/MR integrates a USB-OTG full-speed controller, allowing a single chip to act as a USB device (CDC/HID/MSD) or USB host (mass storage, HID keyboard/mouse). Designers can build USB-to-UART bridges, USB audio class interfaces, or USB host mass-storage readers without an external ULPI/UTMI transceiver. The 53 GPIO plus 80 MHz headroom process USB enumeration and class driver stack efficiently, while 512 KB Flash accommodates full USB descriptors plus composite-device code. Typical companion devices include USB Type-C configuration channels and overvoltage protection ICs at the connector.
Recommandé

Principaux différenciateurs
- Combines USB-OTG, dual CAN, and 10/100 Ethernet MAC on a single 80 MHz MIPS32 M4K core (vs PIC32MX440F512HT-80V/MR)
- Higher 105C operating temperature vs typical 85C grade (vs PIC32MX695F512HT-80I/MR)
- 512 KB Flash and 128 KB SRAM integrated into the same die (vs PIC32MX350F256HT-V/MR)
Notes de conception
Operate the PIC32MX695F512HT-80V/MR from a regulated 3.3V rail within 2.5V-3.6V per Microchip's family datasheet. Place 100 nF decoupling on each VDD/VSS pin pair plus a bulk 4.7-10 uF tantalum or ceramic at the package. Add a ferrite bead plus 10 uF cap if the 3.3V is shared with a noisy switching regulator; Ethernet MAC activity can amplify supply ripple. The 105C V grade still requires the rail to stay within spec at worst-case ambient.
The 64-pin QFN has an exposed thermal pad that MUST be soldered to a copper ground plane with thermal vias for heatsinking, per Microchip's QFN PCB layout guidelines. Without proper thermal pad bonding, junction-to-ambient resistance rises dramatically and the part can throttle or fail under sustained 80 MHz operation. Use at least 4 thermal vias in a 0.3 mm pitch grid connecting the pad to a 1 square inch inner-plane copper pour.
Common pitfalls include: (1) leaving the unused Ethernet PHY interface pins floating - tie them per datasheet; (2) forgetting the external 25 MHz crystal or crystal-oscillator load capacitors on OSC1/OSC2 - Ethernet MAC requires stable 25 MHz reference; (3) routing analog ADC traces (AN12-AN15, VREF+, VREF-) over digital switching signals; (4) using a 5V supply - the part is NOT 5V tolerant. Configure USB DP/DN to use the dedicated USB pins, not remapped GPIO, and add USBLC6-2 ESD protection.
Route the Ethernet RMII interface traces length-matched within 50 mils to maintain 50 MHz timing margins. Keep RMII traces short (under 1 inch) and adjacent to a continuous ground plane. The USB DP/DN pair requires 90 ohm differential impedance with no stubs; route over a clean reference plane and add ESD protection (e.g., USBLC6-2SC6) near the connector. The exposed thermal pad must be soldered to a continuous ground pour for thermal and electrical performance.
Informations de conformité
RoHS compliant per Microchip product page and 64-pin QFN (MR suffix) lead-free designation. The V temperature grade is not AEC-Q100 qualified; for automotive designs requiring AEC-Q100, choose the Q-1 part variant.
