USB Device Controller
FEDL60851E-02
Issue Date: Dec. 16, 2002
GENERAL DESCRIPTION
The ML60851E is a general purpose Universal Serial Bus (USB) device controller. The ML60851E 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 this device.
