Description

The TI380C25 is a single-chip network-communications processor (commprocessor) that supports token-ring local area networks (LANs) at data rates of 16 Mbps or 4 Mbps. The TI380C25 conforms to ISO 8802-5/IEEE 802.5-1992 standards and has been verified to be completely IBM Token-Ring Network compatible. By integrating the essential control building blocks needed on a LAN-subsystem card into one device, the TI380C25 ensures that this IBM compatibility is maintained in silicon.

The high degree of integration of the TI380C25 makes it a virtual LAN subsystem on a single chip. Protocol handling, host-system interfacing, memory interfacing, and communications processing are all provided through the TI380C25. To complete LAN-subsystem design, only the network-interface hardware, local memory, and minimal additional components such as PAL® devices and crystal oscillators need to be added.
