W812

The W812, Oki Semiconductor's 1394 Link Layer Controller, is IEEE 1394-1995 compliant and features an embedded high-performance application bus interface. This device performs data packaging according to the IEEE 1394-1995 Standard, and bidirectional asynchronous/isochronous data transfers to/from an IEEE 1394 serial bus physical layer (PHY) device.

The W812 is optimized for use as a peripheral link layer controller. The application bus interface, which transfers data between a FIFO and the host controller, is designed for highly efficient transport. Oki also provides an optional FIFO controller, the W812-F to readily interface with the W812.

Oki's W812 accommodates different application needs by using a flexible architecture which to support both asynchronous and isochronous data transfers or only asynchronous data transfers. This technology give system designers the maximum flexibility in their design.
