DM9051
SPI to Ethernet MAC Controller
2. General Description
The DM9051 is a fully integrated and cost-effective
low pin count single chip Fast Ethernet controller with
SPI interface, a 10/100M PHY and 4K Dword SRAM.
It is designed with low power and high performance
SPI interface that support 5V/3.3V IO tolerance.
The DM9051 supports SPI interfaces to internal
memory accesses for various processors. The PHY of
the DM9051 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 DM9051 to take the maximum advantage of
its abilities. The DM9051 also supports IEEE 802.3x fullduplex flow control.
