Overview
The STULPI01BTBR is a high-speed USB 2.0 transceiver developed by STMicroelectronics, compliant with ULPI (UTMI+ low pin interface) and OTG (On-The-Go) specifications. This component provides a complete physical layer solution for high-speed USB host, device, or OTG dual-role cores. It enables USB ASICs to interface with the physical layer of the USB through a 12-pin interface, incorporating features such as VBUS comparators, an ID line detector, USB differential drivers and receivers, and a complete ULPI register map and interrupt generator. The STULPI01BTBR is particularly suited for mobile and battery-powered applications due to its low-power consumption, power-down operating mode, and compact package dimensions.
