1.1 System Description

The DM9621 USB to 10/100Mbps Fast Ethernet controller is a high performance and highly

integrated ASIC with embedded SSRAM for packet buffering. It enables low cost and

affordable Fast Ethernet network connection to desktop, notebook PC, and embedded

system using popular USB ports.

It has an USB interface to communicate with USB host controller and is compliant with USB

specification V1.0, V1.1 and V2.0. It implements 10/100Mbps Ethernet LAN function based on

IEEE802.3, and IEEE802.3u standards.

DM9621 integrates an on-chip 10/100Mbps Ethernet PHY to simplify system design and

provides an optional Reduce media-independent interface (RMII).
