PIC32MX664F064HT-I/PT 개요
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, data RAM, and programmable peripherals. The PIC32MX family specifically uses the MIPS32 M4K core - a 32-bit RISC architecture running at up to 80 MHz - and sits within Microchip's broader portfolio of PIC microcontrollers. MCUs in this class bridge the gap between 8/16-bit controllers and full application processors, and they typically operate without an external memory bus or operating system. The PIC32MX5/6/7 series with integrated Ethernet and USB targets connected-node designs that previously required a separate network processor or external PHY.
Key features include 64 KB (64K x 8) Flash program memory, 32 KB SRAM, 51 digital I/O pins, four DMA channels, two I2C, two SPI, two UART, five 16-bit timers, five input-capture and five output-compare modules, an RTCC, and a 10-bit 1 MSPS ADC with up to 16 channels. The integrated 10/100 Ethernet MAC with RMII/MII interface and USB 2.0 Full-Speed OTG reduce external component count, while the parallel master port (PMP) supports external bus expansion. Hardware crypto/hash is not included on this part.
Architecturally, the M4K core executes most instructions in a single cycle, achieving 1.56 DMIPS/MHz, and the dual-set shadow register file enables fast interrupt response. The 64 KB Flash is organized for self-programming under firmware control, and the 32 KB RAM is large enough for full TCP/IP stacks such as Microchip's MPLAB Harmony networking services.
Typical applications include industrial Ethernet nodes, USB peripherals and device/host/OTG bridges, home-automation gateways, and M2M/IoT connected sensors. Designers use this part when they need a single-chip solution that combines an MCU with deterministic real-time control and Ethernet/USB connectivity.
When designing, ensure the external Ethernet PHY magnetics and 25 MHz oscillator meet the RMII/MII timing budget; for USB-OTG operation, add a 100 uF bulk capacitor on VBUS to meet inrush-current requirements. Keep analog and digital grounds separated under the IC and tie them at a single point near the chip.

일반적인 애플리케이션
PIC32MX664F064HT-I/PT 적합 용도: 7 애플리케이션s: Industrial Ethernet Node, USB Device/Host/OTG Peripheral, Home Automation Gateway, M2M / IoT Connected Sensor, USB-to-UART / USB-to-SPI Bridge, Audio Streaming over Ethernet (Dante/AES67 Lite), Industrial HMI / Control Panel.
Industrial Ethernet Node
The PIC32MX664F064HT-I/PT is well suited for industrial Ethernet nodes thanks to its integrated 10/100 Mbit MAC (RMII/MII), 80 MHz MIPS32 core, and -40C to +85C industrial temperature rating. The on-chip MAC eliminates an external network controller, leaving only a PHY, isolation transformers, and an RJ45 jack external to the MCU. With 64 KB Flash and 32 KB RAM, the part runs Microchip's MPLAB Harmony TCP/IP stack alongside a Modbus TCP, EtherNet/IP, or PROFINET application layer. The four DMA channels offload packet-copy and ADC operations so the CPU can service the real-time control loop deterministically.
추천
USB Device/Host/OTG Peripheral
The PIC32MX664F064HT-I/PT integrates USB 2.0 Full-Speed OTG, making it ideal for USB peripherals such as data loggers, HID devices, and CDC-class virtual COM ports. The OTG controller supports both host and device roles, enabling dual-role designs like USB memory-stick data transfer or smartphone charging ports. The 32 KB SRAM comfortably holds USB descriptors and ring buffers, while the DMA channels handle bulk transfer endpoints without CPU intervention. Designers only need an external 100 uF bulk capacitor on VBUS to meet USB-OTG inrush requirements.
추천
Home Automation Gateway
The PIC32MX664F064HT-I/PT acts as a low-cost home-automation gateway connecting Wi-Fi/Zigbee/Z-Wave bridges to Ethernet backhaul. Its 80 MHz MIPS32 core and 32 KB RAM run a TCP/IP stack plus application logic for sensor aggregation or cloud MQTT publishing. The 51 GPIO and multiple UART/SPI/I2C peripherals give designers a wide margin for connecting multiple radios and user-interface buttons/LEDs. Industrial temperature rating ensures reliable operation in attic or garage enclosures.
추천
M2M / IoT Connected Sensor
For machine-to-machine (M2M) and IoT sensor nodes, the PIC32MX664F064HT-I/PT provides on-chip Ethernet and USB, removing the need for an external MCU+network processor stack. The 10-bit 1 MSPS ADC with up to 16 channels samples analog sensors at high speed, and the four DMA channels stream ADC results into memory without CPU load. Low-cost sensor hubs use this part to publish temperature, pressure, or flow telemetry over Ethernet to a SCADA or cloud server. The 2.3 V to 3.6 V supply range matches battery-backed or PoE-powered designs.
추천
USB-to-UART / USB-to-SPI Bridge
Designers commonly use the PIC32MX664F064HT-I/PT as a USB-to-UART or USB-to-SPI bridge, taking advantage of its USB device controller and dual UART/SPI peripherals. The 80 MHz core handles USB enumeration and protocol conversion with low latency, and the 64 KB Flash allows on-chip firmware update via USB DFU. Industrial temperature rating and small TQFP footprint simplify integration inside cable assemblies or compact dongles.
추천
Audio Streaming over Ethernet (Dante/AES67 Lite)
The PIC32MX664F064HT-I/PT can serve as a low-channel-count audio-over-IP endpoint thanks to its Ethernet MAC, DMA channels, and I2S peripheral. The 32 KB SRAM buffers compressed audio packets, while the DMA engines move audio samples between I2S and network memory autonomously. Industrial-grade temperature and deterministic interrupt response make this part suitable for fixed-install audio nodes.
추천
Industrial HMI / Control Panel
For human-machine interface (HMI) panels and operator-control displays, the PIC32MX664F064HT-I/PT drives character or graphical LCDs via its parallel master port (PMP) and reads keypads through GPIO. The Ethernet MAC enables remote HMI configuration and SCADA connectivity, while the USB-OTG port supports firmware updates from a service laptop. Designers appreciate the 51 GPIO, five 16-bit timers, and 10-bit ADC for backlight control, buzzer drive, and analog sensor readout.

설계 노트
Estimated: At 80 MHz full operation with Ethernet MAC and USB active, the PIC32MX664F064HT-I/PT typically draws 60-80 mA from the 3.3 V rail. Place a 10 uF bulk capacitor plus 0.1 uF decoupling on each VDD pin pair (pins 12/11, 20/19, 32/31, 40/39, 52/51, 60/59) to suppress switching noise. For USB-OTG host mode, add a 100 uF bulk capacitor on VBUS to meet inrush-current requirements per the USB specification.
Route the 50 ohm Ethernet RMII/MII traces with controlled impedance (typically 50 ohm single-ended to ground) and keep total trace length below 50 mm. Match the 25 MHz reference oscillator trace length to the ETH_CLK pin to within 2 mm of the PHY to avoid duty-cycle distortion. Place the PHY close to the RJ45 jack with the magnetics between them to minimize EMI and common-mode noise.
Do not assume the H (high-pin-count) and L (low-pin-count) variants of the PIC32MX664 family share identical pinout - the L variant reduces pin count by removing dedicated peripherals. When migrating between H and L parts in the same 64-pin TQFP, verify pin function remapping in MPLAB X. Also, the MCLR pin (pin 64) must be pulled up to VDD via a 10 kohm resistor; do not leave it floating.
Separate analog and digital ground planes under the PIC32MX664F064HT-I/PT to prevent ADC noise coupling. Place the ADC reference decoupling capacitor (0.1 uF) as close as possible to the AVSS/AVDD pins if used. For best ADC performance, use the lowest pin-count analog input channel possible and avoid routing high-frequency digital traces adjacent to analog traces.
