Chapter 1 General Description
SMSC LAN9117
The LAN9117 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 LAN9117 has been specifically architected to provide the highest performance possible for any
16-bit application. The LAN9117 is fully IEEE 802.3 10BASE-T and 802.3u 100BASE-TX compliant.
The LAN9117 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 microprocessors and microcontrollers as well as 32-bit microprocessors exposing a
16-bit external bus. The LAN9117 includes large transmit and receive data FIFOs with a high-speed
host bus interface to accommodate high bandwidth, high latency applications. In addition, the LAN9117
memory buffer architecture allows the most efficient use of memory resources by optimizing packet
granularity.
Applications
The LAN9117 is well suited for many medium-high-performance embedded applications, including:
The LAN9117 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 LAN9117 can
automatically generate flow control packets to the remote node, or assert back-pressure on the remote
node by generating network collisions.
The LAN9117 supports numerous power management and wakeup features. The LAN9117 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.
