PHILIPS is distributing a low pin, high speed, USB transceiver interface.
UTMI+ Low Pin Interface (ULPI) enables chip and system designers to connect a high speed USB transceiver to USB core logic embedded in application-specific integrated circuits (ASICs) and systems on chip (SoCs). The ULPI specification covers USB host, device and on the go (OTG) implementations.
By using the ULPI standard interface instead of proprietary interfaces, ASIC and SoC designers will reduce design time, simplify testing and ensure interoperability with USB transceivers. ULPI specifies a 12-pin interface between host, device, and OTG functionality on an ASIC or SoC, and an external USB transceiver. As a result, more USB functionality can be integrated, leading to a reduction in the pin-count of the transceiver from 100 to about 30.
USB is the most widely deployed connection interface for quick transfers of information on PCs, printers, digital cameras, personal digital assistants (PDAs), MP3 players, mobile phones, monitors, and other digital consumer electronics. Using USB, consumers can easily establish high-speed connections between products to transfer digital files like pictures and multimedia content.
The transceiver is endorsed by USB providers including ARC International, Conexant, Mentor Graphics, Philips, Standard Microsystems, and TransDimension.
