What is a PIC32MX microcontroller? The PIC32MX family is Microchip's general-purpose 32-bit MCU line built on the MIPS M4K core. Within the broader taxonomy, a PIC32MX belongs to: 32-bit microcontroller -> RISC MCU -> embedded processor -> semiconductor IC. The M4K core executes the MIPS32 instruction set with optional MIPS16e code compression (up to 40% smaller code), a 5-stage Harvard pipeline, and a hardware multiplier/divider. This part targets "connectivity" applications (USB + Ethernet + CAN) that previously required external PHY or secondary MCUs.
Key features include 512 KB (512K x 8) Flash program memory, 128 KB SRAM, a 16-bit wide instruction path, and peripheral pin select for flexible I/O mapping. The integrated Ethernet MAC supports both MII and RMII interfaces to standard PHYs, while the USB-OTG controller supports device, host, and On-The-Go roles without an external PHY. Eight DMA channels (4 dedicated to USB/Ethernet plus 4 general-purpose) offload data movement from the CPU, sustaining high-throughput streaming at the 80 MHz core clock.
Typical applications include industrial Ethernet nodes (Modbus TCP, EtherNet/IP gateways), USB peripherals and embedded hosts (mass storage, HID, CDC), building automation controllers, point-of-sale terminals, and automotive infotainment/telematics prototypes. The combination of USB-OTG and Ethernet on a 100-pin TQFP makes the device attractive for retrofitting older 8/16-bit designs that need to add IP connectivity without moving to a Linux-class SoC.
When designing with this part, ensure the 2.5V/3.3V supply rails are properly decoupled (100 nF + bulk) and that the Ethernet PHY reference clock and magnetics meet IEEE 802.3 requirements. Programming is supported by MPLAB X IDE, MPLAB Harmony framework, and the PICkit/Snap/ICD debug probes; the device is pin-compatible across the PIC32MX5xx/6xx/7xx sub-families, simplifying board reuse.

典型應用
PIC32MX695F512L-80I/PF 適用於 6 應用s: Industrial Ethernet Gateway / Node, USB Device / Host / OTG Peripherals, Building Automation Controllers, Point-of-Sale (POS) Terminals, Data Acquisition & Industrial Sensor Hubs, Automotive Infotainment / Telematics Prototypes.
Industrial Ethernet Gateway / Node
The PIC32MX695F512L-80I/PF is well suited for industrial Ethernet nodes such as Modbus TCP gateways, EtherNet/IP adapters, and PROFINET slave controllers because it integrates a 10/100 Ethernet MAC with MII/RMII, 512 KB Flash for the TCP/IP stack, and 128 KB SRAM for socket buffers. The 80 MHz MIPS M4K core sustains 105 DMIPS which keeps latency low for real-time protocols. Engineers pair the MCU with an external PHY (e.g., KSZ8041 for RMII) plus an isolation transformer. Compared with a discrete Ethernet controller + 8-bit MCU solution, the single-chip design cuts PCB area roughly in half. The industrial -40C to +85C temperature grade supports cabinet and factory-floor deployment.

USB Device / Host / OTG Peripherals
The PIC32MX695F512L-80I/PF integrates USB 2.0 On-The-Go with PHY on-chip, eliminating the external PHY chip required by many competing MCUs. At 80 MHz with 8 DMA channels (4 dedicated to USB), it comfortably handles USB device class stacks (CDC, HID, MSD, vendor), USB host stacks (mass storage, keyboards, printers), and dual-role OTG negotiation. Typical use cases include USB data loggers, programmable USB test instruments, USB-to-UART bridges, and embedded host products such as USB-to-SD card copiers. With 512 KB Flash, full USB host stacks including mass-storage file systems fit without external boot ROM. The 100-pin TQFP gives designers all 85 I/O for control planes alongside the USB D+/D- pins.
推薦
Building Automation Controllers
Building automation controllers (BACnet MS-TP gateways, BACnet/IP nodes, KNX-to-IP bridges, smart thermostats, lighting controllers) benefit from the PIC32MX695F512L-80I/PF's combination of Ethernet, CAN, multiple UARTs, and 10-bit ADC for sensor front-ends. The 128 KB SRAM supports BACnet/IP concurrent connections, while the 512 KB Flash holds the full BACnet/IP or KNXnet/IP stack plus application logic. The on-chip 10-bit 1 Msps ADC with DMA scans thermistor or 4-20 mA current-loop inputs without CPU intervention. Industrial temperature grade and low power modes make it appropriate for 24/7 wall-mounted or DIN-rail controllers. CAN 2.0B permits direct interface to HVAC and lighting subsystems without a separate transceiver MCU.
推薦
Point-of-Sale (POS) Terminals
POS terminals integrate a magnetic-stripe reader, EMV smart-card controller, NFC reader, keypad, LCD, and Ethernet/Wi-Fi backhaul. The PIC32MX695F512L-80I/PF hosts USB-OTG for barcode scanners and receipt printers, plus Ethernet MAC for IP-based payment processing. Its 80 MHz MIPS core runs TLS handshakes for payment APIs within reasonable latency. The 512 KB Flash is sufficient for a small embedded web client, payment-payload queue, and LCD graphics library. The 85 I/O pins accommodate parallel LCD, keypad matrix, smart-card UART, and multiple serial peripherals simultaneously. PCI-PTS hardware certification belongs to the terminal manufacturer, but the MCU's hardware crypto offload is insufficient, so PIC32MX795 is preferred for higher-security POS designs.
推薦
Data Acquisition & Industrial Sensor Hubs
Industrial sensor hubs aggregate analog and digital signals from multiple sensors and forward them via Ethernet (MQTT, OPC-UA, or simple TCP). The PIC32MX695F512L-80I/PF offers a 10-bit ADC at 1 Msps with up to 16 channels plus dedicated DMA, enabling autonomous multi-channel scanning without CPU load. With 85 I/O pins, designers route UART, SPI, and I2C sensor buses simultaneously. The 128 KB SRAM buffers sampled data between Ethernet transmissions. Typical deployments include vibration monitoring nodes, multi-channel thermocouple loggers, and remote telemetry units (RTUs). The industrial temperature grade and wide 2.5V/3.3V tolerance suit 24V industrial supply rails with simple LDO regulation.
推薦
Automotive Infotainment / Telematics Prototypes
While the PIC32MX695F512L-80I/PF itself is not AEC-Q100 qualified, its 100-pin TQFP, integrated Ethernet, USB-OTG, and CAN 2.0B make it a popular prototyping platform for automotive infotainment research, fleet telematics, and OBD-II gateway prototypes. Designers use it to validate in-vehicle network architectures before moving to AEC-Q100 qualified PIC32 variants. The 80 MHz core and DMA channels sustain CAN bus logging plus Ethernet forwarding concurrently. The 512 KB Flash accommodates CANopen or J1939 protocol stacks, and the 85 I/O provide ample headroom for LCD interfaces and GPIO. Note: production automotive deployments should select Microchip's AEC-Q100 qualified PIC32MX equivalents from the same family.

- Same 100-TQFP footprint with optional hardware crypto engine for TLS (對比PIC32MX575F512L-80I/PF)

設計說明
The PIC32MX695F512L-80I/PF operates from a single 2.5V or 3.3V supply. Decouple the main VDD pins (multiple VDD/VSS pairs around the package) with 100 nF ceramic caps placed as close as possible to each pair, plus a 4.7-10 uF bulk capacitor at the regulator output. The internal core logic draws approximately 60-70 mA at 80 MHz with all peripherals active; add a 1 uF tantalum or ceramic cap on the VDDPLL pin to stabilize the 8 MHz internal PLL multiplier. For USB-OTG operation, the VBUS sense pin (pin 81) requires a voltage divider since 5V VBUS must be scaled to the MCU's 3.3V I/O domain.
For the 100-pin TQFP package, use a 4-layer PCB with continuous ground plane under the MCU and route high-speed signals (Ethernet RMII 50 MHz ref clock, USB D+/D- 480 Mbps) over an unbroken reference plane with controlled 90 ohm differential impedance for USB and 50 ohm single-ended for RMII. Keep Ethernet PHY traces under 50 mm, place the 1:1 isolation transformer within 12 mm of the PHY, and route RMII data/clock traces length-matched within 5 mm. Place a 22 ohm series ferrite bead or resistor on each USB D+/D- line near the connector for EMI suppression, matching the USB 2.0 high-speed specification.
Three common pitfalls: (1) Forgetting the external 8 MHz primary oscillator or relying solely on the internal FRC oscillator causes Ethernet USB-OTG timing jitter - for USB-OTG full-speed, the 48 MHz USB clock must be derived from the PLL, which requires a precise 8 MHz or 12 MHz crystal reference. (2) Configuring peripheral pin select (PPS) registers AFTER disabling the I/O - PPS must be unlocked, mapped, and then locked before peripheral use. (3) Exceeding the absolute maximum VDD of 3.6V during in-circuit serial programming (ICSP) burns the MCU; the ICD/PICkit programmer must source 3.3V, not 5V. Always populate the ICSP header with a 10 kohm pull-down on MCLR to prevent spurious resets.
