High Performance Single-Chip 10/100 Non-PCI Ethernet Controller
Datasheet
Chapter 1 General Description
The LAN9118 is a full-featured, single-chip 10/100 Ethernet controller designed for embedded
applications where performance, flexibility, ease of integration and system cost control are required.
The LAN9118 has been specifically architected to provide the highest performance possible for any
given architecture. The LAN9118 is fully IEEE 802.3 10BASE-T and 802.3u 100BASE-TX compliant.
The LAN9118 includes an integrated Ethernet MAC and PHY with a high-performance SRAM-like slave
interface. The simple, yet highly functional host bus interface provides a glue-less connection to most
common 16-bit and 32-bit microprocessors and microcontrollers. The LAN9118 includes large transmit
and receive data FIFOs with a high-speed host bus interface to accommodate high bandwidth, high
latency applications. In addition, the LAN9118 memory buffer architecture allows the most efficient use
of memory resources by optimizing packet granularity.
Applications
The LAN9118 is well suited for many high-performance embedded applications, including:
High-end cable, satellite and IP set-top boxes
Video distribution systems
Multi-room PVR (Personal Video Recorder)
Digital video recorders
High-definition televisions
Digital media clients/servers
Home gateways
The LAN9118 also supports features which reduce or eliminate packet loss. Its internal 16-KByte
SRAM can hold over 200 received packets. If the receive FIFO gets too full, the LAN9118 can
automatically generate flow control packets to the remote node, or assert back-pressure on the remote
node by generating network collisions.
The LAN9118 supports numerous power management and wakeup features. The LAN9118 can be
placed in a reduced power mode and can be programmed to issue an external wake signal via several
methods, including “Magic Packet”, “Wake on LAN” and “Link Status Change”. This signal is ideal for
triggering system power-up using remote Ethernet wakeup events. The device can be removed from
the low power state via a host processor command.
