SAN JOSE, Calif.,Cypress Semiconductor Corp.'s high-speed MoBL-USB TX2 transceiver for mobile handsets now offers a mode that allows all input/output (I/O) pins on its UTMI (USB 2.0 Transceiver Macrocell Interface) interface to be tri-stated.
The MoBL-USB TX2 transceiver, part number CY7C68000A, is optimized for Intel's newest handheld applications processor family (codenamed Monahans) based on the third generation Intel XScale architecture. The MoBL-USB TX2 transceiver is compliant with the UTMI standard, and has been tested in collaboration with Intel Corporation, Santa Clara, Calif.
The new feature allows handset manufacturers to share baseband or application processor general-purpose I/O (GPIO) pins between high-speed USB and other features, such as the camera module, GPS, and DVB-H.
The MoBL-USB TX2 device is put into a "suspend" state when USB is not in use, dropping the typical power consumption to just 8 microamps and allowing the UTMI I/O pins to be tri-stated. This allows the processor to reuse and share the limited GPIO pins for other functions across two or more devices, while extending battery life with the industry's lowest standby power consumption for a USB transceiver, according to the company.
Further details on this feature can be found in a Cypress application note available at www.cypress.com/handsets/MoBL-USBTX2/AN6065.pdf.
The MoBL-USB TX2 transceiver (CY7C68000A) is available now in both 56-ball VFBGA and 56-lead QFN packages. Pricing in 10,000-unit volumes for the MoBL-USB TX2 transceiver starts at $1.49.
