A 400 Mbps 1394 disk controller IC with integrated DRAM

A 400 Mbps, 1394 Disk Controller IC, with 0.75 Mbits of integrated DRAM, in a 0.35 /spl mu/m 5 layer metal CMOS ASIC process is presented. The device makes use of a variety of circuit techniques, to achieve 5 V tolerance, and low jitter clock generation as well as 40 MIPs operation for the embedded RISC. The device provides a flexible architecture which can be easily extended to 800+ Mbps by integrating the 1394 physical layer (PHY) transceivers.
