ULPI (UTMI + Low Pin Interface)

SMSC has joined with other leading connectivity providers to develop the Universal Transceiver Macrocell + Low Pin Interface (ULPI). By enabling low pin count transceiver connectivity, ULPI technology will allow designers to aggressively drive process technology advancements without redesigning analog blocks, serving to reduce overall systems costs.

SMSC supports the royalty-free ULPI specification and is proud to offer the industry's first ULPI transceiver to achieve the USB-IF's Hi-Speed certification. The ULPI specification is now available publicly on the ULPI Working Group Web Site. For further information, please contact
