DM9000BI
Industrial-temperature Ethernet Controller with General Processor Interface
1. General Description
The DM9000BI is a fully integrated and cost-effective
Industrial-temperature low pin count single chip Fast
Ethernet controller with a general processor interface,
a 10/100M PHY and 4K Dword SRAM. It is designed
with low power and high performance process
interface that support 3.3V with 5V IO tolerance.
The DM9000BI supports 8-bit and 16-bit data
interfaces to internal memory accesses for various
processors. The PHY of the DM9000BI can interface to
the UTP3, 4, 5 in 10Base-T and UTP5 in 100Base-TX with
HP Auto-MDIX. It is fully compliant with the IEEE 802.3u
Spec. Its auto-negotiation function will automatically
configure the DM9000BI to take the maximum advantage of
its abilities. The DM9000BI also supports IEEE 802.3x full-
duplex flow control.
