DM9010BIEP Product Brief
Industrial-temperature 10/100 Mbps Single Chip Ethernet
Controller With General Processor Interface
Feb. 2012 Rev.1.0
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.
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.
