Dear customers,
About the change in the name such as "Oki Electric Industry Co. Ltd." and
"OKI" in documents to OKI Semiconductor Co., Ltd.
The semiconductor business of Oki Electric Industry Co., Ltd. was succeeded to OKI
Semiconductor Co., Ltd. on October 1, 2008.
Therefore, please accept that although
the terms and marks of "Oki Electric Industry Co., Ltd.", “Oki Electric”, and "OKI"
remain in the documents, they all have been changed to "OKI Semiconductor Co., Ltd.".
It is a change of the company name, the company trademark, and the logo, etc. , and
NOT a content change in documents.

ML60851E
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.

•
Supports three types of transfer; control transfer, bulk transfer, and interrupt transfer
•
Built-in FIFOs for control transfer
Two 8-byte FIFOs (one for receive FIFO and the other for transmit FIFO)
•
Built-in FIFOs for bulk transfer (available for either receive FIFO or transmit FIFO)
One 64-byte FIFO
Two 64-byte FIFOs
•
Built-in FIFO for interrupt transfer
