   Die Pinbelegung des National Semiconductor DP8390DN
 

















   General Description
   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 NIC is the heart of a three chip set that implements the complete
   IEEE 802.3 protocol and node electronics as shown below. The others
   include the DP8391 Serial Network Interface (SNI) and the DP8392 
   Coaxial Transceiver Interface (CTI).
