Controller adds high-speed USB peripheral connectivity to storage hungry portables

Oxford Semiconductor has introduced a high-speed USB peripheral controller designed to help maximize data transfer speeds of memory rich portable products including smart phones, media players, PDAs, and GPS systems.  Compatible with USB specification revision 2.0, the OXU200 supports communication with PC and laptop host systems at the high-speed USB data rate.

With a 16-bit SRAM-like memory mapped interface and a flexible I/O voltage range of 1.65V to 3.6V, the controller provides seamless interface to all the most popular embedded microprocessors and DSPs.  8Kbytes of on-chip SRAM are included and a DMA slave channel helps lower system CPU utilization and ensure high data throughput. 

Needing just a single 3.3V supply, the low power OXU200 is ideal for mobile applications requiring a combination of low power consumption and high performance.  The controller features an ultra low power sleep mode and a power preserving suspend state to help extend system battery life. 

To reflect the board space constraints faced by portable system designers, Oxford is offering the OXU200 in a choice of space saving packages: a 12mm x 12mm 100-pin LQFP and a 6mm x 6mm 64-ball BGA package.  Both chip packages are RoHS compliant and support an operating temperature range of -40°C to 85°C.

The OXU200 is supported with USB device drivers and the Oxford Semiconductor USBLink® software suite.  Low-level controller drivers for other native USB peripheral stacks are also available, such as those included with Windows® CE and Linux® 2.6.X.

In 10K volumes, the OXU200 high-speed USB peripheral controller is priced at $3.45 in the LQFP package and $3.85 in the BGA package.  Production begins in Q1’07.
