General Description

The SMC91C100 FEAST is a high-speed network controller designed to facilitate the implemetation of Fast Ethernet adapters and connectivity products.

It contains a dual speed CSMA/CD engine that implements the MAC portion of the CSMA/CD protocol at 10 and 100 Mbps and couples it with a lean and fast data and control path system architecture to ensure data movement with no bottlenecks at 100 Mbps.

Memory management is handled using a unique MMU (Memory Management Unit) architecture and a 32-bit wide data path.

Key Features

  •         Dual Speed CSMA/CD Engine (10 Mbps and 100 Mbps) Compliant with IEEE 802.3 100BASE-T Specification Supports 100BASE-TX, 100BASE-T4, and 10BASE-T Physical Interfaces 32 Bit Wide Data Path (Into Packet Buffer Memory) Support for 32 and 16 Bit Buses Support for 32, 16 and 8 Bit CPU Accesses Synchronous, Asynchronous and Burst DMA Interface Mode Options 128 Kbyte External Memory        Built-in Transparent Arbitration for Slave Sequential Access Architecture Flat MMU Archi.
