Microchip USB3340-EZK-TR: High-Speed USB 2.0 ULPI Transceiver for Embedded Systems
The increasing demand for high-speed data transfer in embedded applications has made robust USB interfaces more critical than ever. The Microchip USB3340-EZK-TR stands out as a highly integrated, low-power USB 2.0 transceiver designed specifically to meet these demands. Utilizing the ULPI (UTMI+ Low Pin Interface) standard, this IC provides a compact and efficient bridge between a USB host or device controller and the physical USB bus, making it an ideal solution for space-constrained and power-sensitive designs.
A key advantage of the USB3340 is its compliance with the USB 2.0 specification, supporting high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) operations. Its ULPI interface drastically reduces the number of signals required to connect to a system-on-chip (SoC) or microcontroller—from over 20 signals down to just 12. This significant pin-count reduction simplifies PCB layout, minimizes potential noise issues, and allows for the use of smaller, more cost-effective processors that lack a built-in USB PHY.
The device is engineered for exceptional signal integrity and robust performance. It features integrated termination resistors and sophisticated circuitry that ensures reliable data transmission even in electrically noisy environments common to embedded systems. Furthermore, its very low power consumption extends battery life in portable applications, and its advanced power management capabilities include multiple low-power states.
Typical applications are vast and include:

Consumer Electronics: Smartphones, digital cameras, and portable media players.
Industrial and IoT: Data loggers, industrial controllers, and IoT gateways.
Computing Peripherals: Printers, scanners, and external storage devices.
Automotive Infotainment Systems.
Housed in a compact 32-pin QFN package, the USB3340-EZK-TR offers a perfect blend of performance, integration, and physical size. Its design accelerates time-to-market by simplifying the implementation of high-speed USB functionality, reducing both development complexity and overall system cost.
ICGOODFIND: The Microchip USB3340-EZK-TR is a premier ULPI transceiver that delivers high-speed USB 2.0 connectivity with minimal design footprint. Its low pin count and low power operation make it an superior choice for developers seeking to add reliable, high-performance USB capabilities to their embedded designs efficiently.
