DM9621ANP
USB2.0 to 10/100M Fast Ethernet Controller
2. General Description
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.
The DM9621ANP USB2.0 to 10/100Mbps Fast
Ethernet controller with 0.18um CMOS technology is
a high performance and highly integrated ASIC with
embedded 13KB SRAM for packet buffering. It
enables low cost and affordable Fast Ethernet
network connection to desktop, notebook PC, and
embedded system using popular USB ports.
DM9621ANP integrates an on-chip 10/100Mbps
Ethernet PHY to simplify system design and provides
an optional media-independent interface (RMII).
It has an USB interface to communicate with USB
