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
