The DP8390D�NS32490D Network Interface Controller (NIC) is a microCMOS VLSI device designed to ease interfacing with CSMA�CD type local area networks including Ethernet� Thin Ethernet (Cheapernet) and StarLAN�. The NIC implements all Media Access Control (MAC) layer functions for transmission and reception of packets in accordance with the IEEE 802�3 Standard. Unique dual DMA channels and an internal FIFO provide a simple yet efficient packet management design. To minimize system parts count and cost, all bus arbitration and memory support logic are integrated into the NIC. The document also describes the features and characteristics of the product.
