9 / 126 page High Performance Single-Chip 10/100 Non-PCI Ethernet Controller Datasheet SMSC LAN9118 9 Revision 1.1 (05-17-05) 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. |
