NXP Semiconductor unveils ULPI Hi-speed USB transceiver for mobile phone | Tech Femina

NXP Semiconductors has unveiled its new generation UTMI+ Low-Pin Interface (ULPI) Hi-Speed USB transceivers for mobile phones. The size of the smallest USB transceiver is 2.2×2.25×0.6 mm, which fulfills the specific needs of ultra-slim handset designs and other portable devices. NXP’s transceivers consumes only 0.5 μA current only in power down mode to avoid battery drain. The NXP’s transceiver contains four members, including ISP1504x1, ISP1508, ISP1702 and ISP1703 with industry specifications, including ULPI Rev. 1.1, USB On-The-Go (OTG) Rev. 1.2 and USB Rev. 2.0. All transceivers support wide range of input supply voltage of 3.0V to 4.5V for mobile phones. It has host, peripheral and OTG functionality. ISP1508, ISP1702 and ISP1703 address lower system voltage levels with their VCC (I/O) of 1.4V to 1.95V, while some can be pin-selected for data rate (SDR) or double data rate (DDR) interface operation. In addition, all transceiver support USB charger detection, and external charge pump for OTG function. The ULPI transceiver interface allow chips and systems designers to connect a Hi-Speed USB transceiver to USB core logic embedded in Application-Specific Integrated Circuits (ASICs) and Systems-on-Chip (SoCs). Even, ASIC and SoC designers can reduce design time and also simplify testing and ensure interoperability with USB transceivers Via: Digit Times
