Ethernet Controller
The Stellaris® Ethernet Controller consists of a fully integrated media access controller (MAC) and
network physical (PHY) interface. The Ethernet Controller conforms to IEEE 802.3 specifications
and fully supports 10BASE-T and 100BASE-TX standards.
The Stellaris Ethernet Controller module has the following features:
â Conforms to the IEEE 802.3-2002 specification
â 10BASE-T/100BASE-TX IEEE-802.3 compliant. Requires only a dual 1:1 isolation transformer
interface to the line
â 10BASE-T/100BASE-TX ENDEC, 100BASE-TX scrambler/descrambler
â Full-featured auto-negotiation
â Multiple operational modes
â Full- and half-duplex 100 Mbps
â Full- and half-duplex 10 Mbps
â Power-saving and power-down modes
â Highly configurable
â Programmable MAC address
â LED activity selection
â Promiscuous mode support
â CRC error-rejection control
â User-configurable interrupts
â Physical media manipulation
â MDI/MDI-X cross-over support through software assist
â Register-programmable transmit amplitude
â Automatic polarity correction and 10BASE-T signal reception
â Efficient transfers using Micro Direct Memory Access Controller (µDMA)
â Separate channels for transmit and receive
â Receive channel request asserted on packet receipt
â Transmit channel request asserted on empty transmit FIFO
