Description

The TMS380C26 is a single-chip network communications processor (commprocessor) that supports token ring, or Ethernet Local Area Networks (LANs). Either token ring at data rates of 16 Mbps or 4Mbps, or Ethernet at a data rate of 10 Mbps, can be selected. A flexible configuration scheme allows network type and speed to be configured by hardware or software. This allows the design of LAN subsystems which suupport both token ring and Ethernet networks, by electrically or physically switched network front-end circuits.

The TMS380C26 conforms to IEEE 802.5-1989 standards and has been verified to be completely IBMTM Token-Ring compatible. By integrating the essential control building blocks needed on a LAN subsystem card into one device, the TMS380C26 can ensure that this IBM compatibility is maintained in silicon.
