Do you ever get the feeling you could produce a video quicker than the time it takes to download one to your mobile phone? With Cypress Semiconductor's latest MoBLUSB chip, you can just say no to snailpaced downloads and greet up to 480 Mbits/s with open arms.
"The ability to download music at the snap of a finger will accelerate the integration of MP3 players into cell phones," says Rajiv Nema, Cypress's product marketing manager for highspeed USB.
Previously, consumers could use one of three choices for downloading: their cell carrier, a local wireless protocol like infrared or Bluetooth, or a wired solution like full-speed USB. Full-speed USB is the best of the bunch, offering download speeds up to 12 Mbits/s. Bluetooth, which is a distant second, provides 1 Mbit/s.
The 1.8-V MoBL-USB brings highspeed USB integration to mobile phones, with download speeds up to 480 Mbits/s. Its FX2LP18 controller allows for seamless integration with several generations of baseband processors, application processors, ASICs, and application-specific standard products (ASSPs). It comes in a 56-ball very fine-pitch ball-grid-array (VFBGA) that measures 5 mm2. Also, the FX2LP18 typically consumes a mere 20 µA of standby current.
The MoBL-USB devices are fully int grated peripheral controllers that include an 8051 microprocessor, a serial interface engine, a high-speed USB 2.0 transceiver, 16 kbytes of onchip RAM, a FIFO, and a general-programmable interface with up to 24 programmable I/Os.
The FX2LP18 costs $2.49 each in quantities of 1 million units.
