Cypress Semiconductor Corp. announced that it has begun sampling the industry's smallest, most power-efficient, high-speed USB 2.0 controller.

According to the company, the EZ-USB FX2LP (CY7C6803A-X) controller takes advantage of a new advanced process technology for low-power USB devices developed by Cypress to slash power consumption by nearly 50 percent versus leading competitors. As a result, USB peripherals using the EZ-USB FX2LP controller, including mass storage devices and personal media players, are able to operate off of the power of the USB bus.

"Most USB peripherals require bulky external power sources," said Trevor Davis, product marketing manager for the wired business unit in Cypress's Personal Communications Division. "The EZ-USB FX2LP brings a new level of portability to these devices, providing users greater flexibility in their computing environment."

Architecture handles all basic USB functions

Featuring a data rate of 480Mbps, 16KB of on-chip memory and up to 40 programmable I/Os, the second-generation programmable controller includes 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 architecture handles all basic USB functions, enabling the host system's microprocessor to focus on application-specific functions and ensuring sustained high-performance data transfer rates.

Several packaging options are available, including a 8-by-8mm QFN package that is suitable for use in small form-factor mobile applications. To speed development, the FX2LP is pin-compatible with the EZ-USB FX2 and is supported by a wide array of firmware, drivers and reference design tools targeting general-purpose USB and ATA-specific products, as well as those employing isochronous data transfers, video streaming and Microsoft's Media Transfer Protocol.

The EZ-USB FX2LP is the first USB controller to be manufactured with Cypress's new low-power architecture and technology. The company plans to release an entire family of low-power USB products throughout the year.

The new USB device is already available for sampling, with production scheduled in October. Pricing for the product will be start at $4.45 in 10,000-unit quantities.
