NXP Semiconductors recently announced the availability of its new generation UTMI+ Low-Pin Interface (ULPI) Hi-Speed USB transceivers, developed specifically for mobile phone designs.

With the smallest transceiver in the family measuring in at 2.2 x 2.25 x 0.6 mm, in a 0.4 mm ball pitch, NXP's transceiver solutions are the smallest in the market and address the specific needs of today's ultra-slim handset designs and other sleek portable devices. In addition, as the actual USB usage in mobile phones is low compared to overall talk and standby time, NXP's transceivers avoid battery drain by consuming only 0.5 (mu)A in power-down mode.

NXP's family of new generation ULPI Hi-Speed USB transceivers contains four members - ISP1504x1, ISP1508, ISP1702 and ISP1703, all of which are fully compliant with industry specifications, including ULPI Rev. 1.1, USB On-The-Go (OTG) Rev. 1.2 and USB Rev. 2.0. All transceivers support a mobile phone's wider range of input supply voltage of 3.0 V to 4.5 V. A new power-down mode conserves battery with an ultra low-power consumption of less than 0.5 uA when the USB transceiver is not in use.

NXP's ISP504x1, ISP1508 and ISP1702 devices are sampling now, with the first two products in mass production in March and April respectively. Pricing for each device is as follows: $1.30 (U.S.) for ISP1504x1, $1.20 (U.S.) for ISP1702, and $1.10 (U.S.) for ISP1508 and ISP1703.
