The device delivers 1.56 DMIPS/MHz performance and integrates the PIC32MX5/6/7 series peripheral set including 4-channel DMA, multiple UART/SPI/I2C, and a 16-bit ADC.

A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program Flash, non-volatile data storage, RAM, and peripherals such as ADC, timers, and communication interfaces into one package. The PIC32MX6 family is Microchip's mid-range 32-bit MCU line, sitting between the PIC32MX1/2 entry-level parts and the PIC32MZ high-performance series, optimized for embedded connectivity applications.

Key features of the PIC32MX664F128HT-I/PT include 128 KB (128K x 8) Flash with self-programmable Flash, 32 KB SRAM, integrated full-speed USB 2.0 device/host/OTG, integrated 10/100 Mbit Ethernet MAC, 53 usable I/O lines, a 16-channel 16-bit ADC at 500 ksps, two I2C, two SPI, two UART, four 16-bit timers, a real-time clock, and 4-channel DMA. The device supports industrial temperature range of -40C to +85C.

Architecturally, the PIC32MX664F128HT-I/PT uses the MIPS32 M4K core with 5-stage pipeline, MMU-less flat memory map, and hardware multiply/divide. The peripheral set is interconnected via a peripheral bus matrix allowing simultaneous DMA and CPU access for high-throughput applications.

Typical applications include industrial Ethernet nodes, USB-based data loggers, embedded web servers, home automation gateways, and POS terminals. The combination of USB, Ethernet, and 16-bit ADC makes it a strong fit for connected sensing and protocol conversion designs.

When designing, allocate adequate decoupling near VDD/AVDD pins, follow Microchip's TQFP-64 land pattern, and use the MPLAB Harmony framework for peripheral drivers and TCP/IP stack.

Industrial Ethernet Gateway

The PIC32MX664F128HT-I/PT is well-suited for industrial Ethernet gateways because it combines an 80 MHz MIPS32 M4K core with an integrated 10/100 Mbit Ethernet MAC, 4-channel DMA, and 32 KB SRAM sufficient for an embedded TCP/IP stack. The 16-bit ADC and 53 I/O pins handle analog sensor reading and digital I/O for industrial sensors, while the -40C to +85C industrial temperature range supports factory-floor deployment. Paired with a Microchip KSZ8041 PHY, designers can build Modbus TCP, EtherNet/IP, or PROFINET nodes.

🧩

USB Data Logger

For USB data loggers, the PIC32MX664F128HT-I/PT's USB 2.0 Full-Speed device/host/OTG controller allows direct PC connection without an external bridge IC, while 128 KB Flash accommodates logging firmware and a 32 KB buffer for sensor records. The 16-channel 10-bit ADC samples sensor data at up to 500 ksps, and the DMA controller offloads ADC-to-RAM transfers to keep the CPU free for USB stack operations. The TQFP-64 footprint supports compact PCB designs for handheld data loggers.

🌐

Embedded Web Server / IoT Node

The PIC32MX664F128HT-I/PT supports embedded web server applications by running Microchip's MPLAB Harmony TCP/IP stack with HTTP server capability on the 80 MHz MIPS32 core. The integrated Ethernet MAC and 53 I/O pins let the device serve HTML/JSON to remote clients while reading sensors via I2C/SPI. With 128 KB Flash the stack, application logic, and a small web page can co-exist; with -40C to +85C operation the device is suited for outdoor IoT nodes.

📱

POS Terminal / Barcode Scanner

In POS terminals and barcode scanners, the PIC32MX664F128HT-I/PT provides the USB host controller for connecting USB-HID barcode scanners and printers, plus the Ethernet MAC for connecting to backend systems. The 80 MHz core and 4 DMA channels handle real-time barcode decoding (via firmware DSP) without breaking USB throughput. The 32 KB RAM is sufficient for transaction buffers, and the TQFP-64 package fits in slim terminal enclosures.

🏠

Home Automation Gateway

For home automation gateways, the PIC32MX664F128HT-I/PT combines Ethernet (for WAN/LAN uplink) and USB (for ZigBee/Z-Wave dongles) in a single chip, eliminating dual-MCU designs. The 2x UART interfaces support RS-485 or RS-232 wired sensor networks, while 4 timers and 4 DMA channels handle real-time protocol stacks. With 128 KB Flash the device can run a small embedded HTTP server plus a custom automation scheduler.

⚡

Industrial Sensor / Protocol Converter

The PIC32MX664F128HT-I/PT is ideal for protocol conversion modules (e.g. Modbus RTU to Modbus TCP, RS-485 to Ethernet) because the dual UART and Ethernet MAC are both integrated. The 80 MHz MIPS32 core sustains conversion latency below 1 ms with DMA-assisted buffer handling, while 32 KB SRAM holds incoming/outgoing packet buffers. The 16-bit ADC allows local analog sensing, and the TQFP-64 industrial-grade package supports -40C to +85C DIN-rail mounted enclosures.

설계 노트

Place a 0.1 uF decoupling capacitor as close as possible to each VDD pin (pins 8, 26) and a bulk 10 uF tantalum or aluminum electrolytic capacitor on the board-level VDD rail. The PIC32MX664F128HT-I/PT datasheet recommends VDD/VSS pairs to be bypassed at every pin pair to reduce switching noise that can affect the 10-bit ADC readings and the Ethernet MAC PHY interface.

Follow the TQFP-64 land pattern from Microchip's package specification (10x10 mm body, 0.5 mm pitch, 7.5x7.5 mm exposed pad not present - thermal pad not required). Route the USB D+/D- traces as a 90-ohm differential pair with matched length (within 150 mil) to the USB connector. Keep the 50 MHz RMII clock trace to the Ethernet PHY under 50 mm and well-spaced from switching signals.

Do not forget to enable the internal USB 3.3V regulator by leaving the VUSB3V3 pin floating (not grounded) and connecting a 0.1 uF decoupling capacitor. The Ethernet MAC requires an external PHY; the PIC32MX664F128HT-I/PT alone cannot drive an RJ45 jack. For RMII mode, ensure the 50 MHz reference clock is sourced from the PHY (not the MCU) to avoid timing skew.

When using the Ethernet MAC in MII mode (4-bit data bus at 25 MHz), the MCU outputs run at 25 MHz on EMDC/EMDIO/ETXD/ERXD - keep these within 25 mm and avoid running them parallel to the USB differential pair. For RMII mode the bus runs at 50 MHz - shorter traces and ground reference are essential. The MCLR pin should have a 10 kohm pull-up to VDD; do not leave it floating during operation.
