 The
LAN9118 family is a collection of performance-oriented, non-PCI, 10/100 Ethernet
controllers, providing a broad range of solutions and enabling a diverse set of
performance-sensitive embedded applications.
Each
Ethernet controller in the LAN9118 family is based on an enhanced architecture,
which maximizes throughput and minimizes host processor overhead while virtually
eliminating the possibility of lost packets. All family members share a common
footprint and use the same set of software drivers, which provides systems design
flexibility. Designs can be scaled up or down in performance as needed, and one
common design can support a spectrum of system products.
|
| • |
The LAN9118 is targeted for 32-bit applications
requiring high performance, and provides the highest level of performance possible
for a non-PCI 10/100 Ethernet controller. |
|
| • |
The LAN9117 is designed to provide the highest level of performance possible for
16-bit applications. It also has an external MII interface, which can be used
to attach an external PHY. |
| • |
The LAN9116 and LAN9115 are designed for performance-sensitive applications with
less intensive performance requirements. The LAN9116 is for 32-bit host processors,
while the LAN9115 is for 16-bit applications, which may also require an external
PHY. Both devices deliver superior levels of performance. |

| The
LAN9118 family is suitable for any application where traffic is continually flowing
into or out of the Ethernet port. It is ideal for multimedia applications using
Ethernet to carry voice and/or video, and for any Ethernet application sensitive
performance. |
