Product Summary

The L6085IE is a general purpose Universal Serial Bus (USB) device controller. The L6085IE provides a USB interface, control/status block, application interface, and FIFOs. The FIFO interface and two types of transfer have been optimized for BulkOut devices such as printers and BulkIn devices such as digital still cameras and image scanners. In addition, Mass Storage devices are also applicable to the L6085IE.
