Cypress' Full-Featured, High-Speed USB Controller for Mobiles
Cypress Semiconductor Corp. has introduced the world's first 1.8-volt high-speed USB 2.0 programmable microcontroller. The new MoBL-USB FX2LP18 controller delivers lightning-fast downloads of music files, photos and videos in mobile handsets. Without high-speed USB, it can take up to 30 to 40 seconds to download a typical music file; with the new Cypress solution, that same download takes about two to three seconds, depending on the cell phone architecture.
The new MoBL-USB FX2LP18 controller is part of an expanding family of MoBL-USB products from Cypress that includes the recently introduced MoBL-USB TX2 transceiver and future products with additional features. It has a 1.8-volt core and supports an I/O voltage range of 1.8 V to 3.3 V to interface seamlessly with several generations of baseband processors, application processors, ASICs and ASSPs. Offered in a 56-ball VFBGA (Very Fine Pitch Ball Grid Array) package that measures only 5 mm x 5 mm with 0.5-mm ball pitch, the new device takes advantage of Cypress's 0.13-micron C8 process technology to slash dynamic and standby power consumption by nearly 80 percent versus the nearest competitors, while offering much greater functionality.
The MoBL-USB FX2LP18 controller is qualified to operate with an industrial temperature rating of -40 degrees C to +85 degrees, a critical requirement for handsets. It has standby current consumption of just 20 uA, enabling customers to maximize battery life on their cell phones. Competing solutions typically consume 160 uA. The device is a fully integrated peripheral controller, including an 8051 microprocessor, a serial interface engine, a high-speed USB 2.0 transceiver, on-chip RAM and FIFO and a general programmable interface. Its unique architecture handles all basic USB functions, enabling the host system's processor to focus on application-specific functions and ensuring sustained high-performance data transfer rates. Featuring a data rate of 480 Mbps, 16 Kbytes of on-chip memory, and 24 programmable I/Os, Cypress's MoBL-USB FX2LP18 solution provides world-class design flexibility.
