New Controller Adds High-Speed USB Peripheral Connectivity to Portables

Permalink: New Controller Adds High-Speed USB Peripheral Connectivity to Portables

Oxford Semiconductor Inc., a California-based provider of connectivity solutions for consumer, storage, multimedia, computing and industrial applications, has announced its latest controller - the OXU200.

The device is a high-speed USB peripheral controller designed to help maximise data transfer speeds of memory rich portable products including PDAs, GPS systems and smart phones. The controller is compatible with USB specification revision 2.0 and supports communication with PC and laptop host systems at the high-speed USB data rate.

The OXU200W has a 16-bit SRAM-like memory mapped interface and a flexible I/O voltage range of 1.65V to 3.6V. It interfaces seamlessly with embedded microprocessors and DSPs. 8Kbytes of on-chip SRAM are included and a DMA slave channel helps lower system CPU utilization and ensures high data throughput. The device needs just a single 3.3V supply and is ideal for mobile applications requiring low power consumption and high performance.

The OXU200 comes in a choice of packages: a 12mm x 12mm 100-pin LQFP and a 6mm x 6mm 64-ball BGA package, both of which are RoHS compliant. They operate in a 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 LQFP package is priced at $3.45 and the BGA package at $3.85. Production is scheduled to commence in the first quarter of 2007.
