USB to Ethernet Controller

 

DM9620A and DM9621A USB to 10/100Mbps Fast Ethernet controllers are high performance and highly integrated ASICs 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.
They have an USB interface to communicate with USB host controller and are compliant with USB specification V1.0, V1.1 and V2.0. Implemented is a 10/100Mbps Ethernet LAN function based on IEEE802.3, and IEEE802.3u standards.
Both ICs integrate an on-chip 10/100Mbps Ethernet PHY to simplify system design and provide an optional Reduce media-independent interface (RMII).
