S3C4510B
ETHERNET CONTROLLER
FEATURES AND BENEFITS
The most important features and benefits of the S3C4510B ethernet controller are as follows:
— Cost-effective connection to an external RIC/Ethernet backbone
— Buffered DMA (BDMA) engine using burst mode
— BDMA Tx/Rx buffers (256 bytes/256 bytes)
— MAC Tx/Rx FIFOs (80 bytes/16 bytes) to support re-transmit after collision without DMA request and to
handle DMA latency
— Data alignment logic
— Endian translation
— Support for old and new media (compatible with existing 10-Mbit/s networks)
— 100-Mbit/s or 10-Mbits/s operation to increase price/performance options and to support phased conversions
— Full IEEE 802.3 compatibility for existing applications
— Media Independent interface (MII) or 7-wire interface
— Station management (STA) signaling for external physical layer configuration and link negotiation
— On-chip CAM (21 addresses)
— Full-duplex mode for doubled bandwidth
— Pause operation hardware support for full-duplex flow control
— Long packet mode for specialized environments
— Short packet mode for fast testing
— PAD generation for ease of processing and reduced processing time
