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, ID line detector, USB differential driver and receivers and 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.
