Cypress Semiconductor Corp. has introduced a high-speed USB 2.0 transceiver available in the industry's smallest package.

The MoBL-USB TX3LP18 transceiver is offered in a 20-pin WLCSP package that measures 2.2mm x 1.8mmalmost three times smaller than a standard golf ball dimple. In addition to having a footprint 20 percent smaller than any competitive solutions, the device offers ultralow power consumption. This combination saves board space and prolongs battery-life for portable applications such as mobile handsets, PDAs, PMPs and GPS units.

The MoBL-USB TX3LP18 transceiver is compliant with the UTMI (USB 2.0 Transceiver Macrocell Interface) + Low-Pin Interface (ULPI) standard. It delivers ultralow power consumption with a 0.5?A nominal sleep mode. In addition to its small size, the device integrates multiple passive components to further reduce boardspace usage and enable smaller end systems. It removes the need for a dedicated 3.3V power supply with a wide input supply voltage range from 3V to 5.8V, and features an integrated phase-locked loop (PLL) to supply USB clocking requirements without a dedicated crystal.

The MoBL-USB TX3LP18 transceiver offers a wide array of features and functions. These include a ULPI-compliant/USB-2.0-certified for device operation, supports for USB 2.0 high-speed (480Mbps) and full-speed (12Mbps), 8bit single data rate (SDR) ULPI data path and integrated regulator with 3- 5.775V. input.

The device operates within the industrial temperature range (-40C to 85C) and offers 13, 19.2, 24 or 26MHz reference for integrated PLL.

The CY7C68003 MoBL-USB TX3LP18 transceiver is available in 2.2mm x 1.8mm WLCSP and in 4mm x 4mm 24-pin QFN packages. The device is currently sampling and is expected to ship in production volumes later this year.
