1.1 System Description

The DM9620/DM9620I USB to 10/100Mbps Fast Ethernet controller is a

industrial-temperature (DM9620I only) 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.

DM9620/DM9620I integrates an on-chip 10/100Mbps Ethernet PHY to simplify system design

and provides an optional media-independent interface (MII/Reverse MII/RMII).
