Product overview
Description
The STULPI01 is a high-speed USB 2.0 transceiver compliant with ULPI (UTMI+ low pin interface) and OTG (On-The-Go) specifications, providing a complete physical layer solution for any high-speed USB host, device or OTG dual-role core. It allows USB ASICs to interface with the physical layer of the USB through a 12-pin interface. It contains VBUS comparators, an ID line detector, USB differential drivers and receivers and a complete ULPI register map and interrupt generator. The STULPI01 transceiver is suitable for mobile applications and battery-powered devices because of its low-power consumption, Power-down operating mode and minimal die/package dimensions.
