• Description: Industrial-temperature 10/100 Mbps Single Chip Ethernet Controller With General Processor Interface
• Manufacturer: DAVICOM [Davicom Semiconductor, Inc.]

1. GENERAL DESCRIPTION
The DM9010BI is a fully integrated and cost-effective
Industrial-temperature single chip Fast Ethernet MAC
controller with a general processor interface, a
10/100M PHY and 16K Byte SRAM. It is designed
with low power and high performance process that
support 3.3V with 5V tolerance.
The DM9010BI also provides a MII interface to connect
HPNA device or other transceivers that support MII
interface.

Interface
The DM9010BI supports 8-bit, 16-bit and 32-bit uP
interfaces to internal memory accesses for different
processors. The PHY of the DM9010BI can interface to
the UTP3, 4, 5 in 10Base-T and UTP5 in 100Base-TX. It is
fully compliant with the IEEE 802.3u Spec. Its
auto-negotiation function will automatically configure the
DM9010BI to take the maximum advantage of its abilities.
The DM9010BI also supports IEEE 802.3x full- duplex flow
control. This programming of the DM9010BI is very simple,
so user can port the software drivers to any system easily.
