DP8390D/NS32490D NIC Network Interface Controller  
General Description  
Table of Contents  
1.0 SYSTEM DIAGRAM  
The DP8390D/NS32490D Network Interface Controller  
(NIC) is a microCMOS VLSI device designed to ease inter-  
facing with CSMA/CD type local area networks including  
Ethernet, Thin Ethernet (Cheapernet) and StarLAN. The  
NIC implements all Media Access Control (MAC) layer func-  
tions for transmission and reception of packets in accord-  
ance with the IEEE 802.3 Standard. Unique dual DMA chan-  
nels 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.

6.0 DIRECT MEMORY ACCESS CONTROL (DMA)  
7.0 PACKET RECEPTION  
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 Net-  
work Interface (SNI) and the DP8392 Coaxial Transceiver  
Interface (CTI).
