DM9621A series

The DM9621A 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. DM9621A integrates an on-chip 10/100Mbps Ethernet PHY to simplify system design and provides an optional Reduce media-independent interface (RMII).
