DM9102D
Single Chip Fast Ethernet NIC Controller
1. General Description
The DM9102D is a fully integrated and cost effective single
chip Fast Ethernet NIC controller. It is designed with low
power and high performance process. It is a 2.5/3.3V device
with 5V tolerance.
The DM9102D provides direct interface to the PCI bus and
supports bus master mode to achieve the high performance
of the PCI bus. It fully complies with PCI 2.2. In the media
side, the DM9102D interfaces to the UTP3, 4, 5 in 10Base-T
and the UTP5 in 100Base-TX. It is fully compliant with the
IEEE 802.3u Spec. The auto-negotiation and
auto-MDI/MDIX function can automatically configure the

DM9102D to take the maximum advantage of its abilities.
The DM9102D also supports IEEE 802.3x’s full-duplex flow
control to prevent the receive overflow of link partner. The
IPv4 IP/TCP/UDP checksum generation and checking can
reduce the system CPU utilization.
The DM9102D supports two types of power management
mechanisms. The main mechanism is based on the OnNow
architecture, which is required for PC99. The alternative
mechanism is based upon the remote Wake-On-LAN
mechanism.
