TI380C27 - Dual-Protocol CommProcessor

General Description

The TI380C27 is a single-chip network-communications processor (commprocessor) that supports token-ring or Ethernet local area networks (LANs).

Token ring at a data rate of either 16 Mbps or 4 Mbps or Ethernet at a data rate of either 10 Mbps (half duplex) or 20 Mbps (full duplex) can be selected.

Key Features

  • 16- or 4-Megabit-per-Second Data Rates.
  • Supports Up to 18K-Byte Frame Size (16-Mbps Operation Only).
  • Supports Universal and Local Network Addressing.
  • Early Token-Release Option (16-Mbps Operation Only).
  • Compatible With the TMS38054.
  • Ethernet Features.
  • 10 Megabit-per-Second Data Rate in Half-Duplex Mode.
  • 20 Megabit-per-Second Data Rate in Full-Duplex Mode.
  • Compatible With Most Ethernet Serial-Network-Interface Devic.
