ThunderLAN Overview
The ThunderLAN family consists of highly integrated, single-chip networking
hardware. It uses a high-speed architecture that provides a complete peripher-
al component interconnect (PCI)- to-10Base-T/AUI (adapter unit interface)
Ethernet solution. It allows the flexibility to handle 100M-bps Ethernet proto-
cols as the user’s networking requirements change.
The TNETE100A, one implementation of the ThunderLAN architecture, is an
intelligent protocol network interface. Modular support for the 100 Base-T
(IEEE 802.3u) and 100VG-AnyLAN (IEEE 802.12) is provided via a media
independent interface (MII). The TNETE110A is the same device without the
MII and is 10M bps only. ThunderLAN uses a single driver suite to support mul-
tiple networking protocols.
ThunderLAN architecture was designed to achieve the following goals:
High performance with low use of host CPU
Simplicity of design
Ease of upgrade to higher speed networks
Freedom of choice of network protocol
ThunderLAN allows a simple system design by integrating a PCI controller, an
internal first in, first out (FIFO) buffer, a LAN controller, and a 10Base-T physi-
cal interface (PHY).
