DATASHEET

Chapter 1 General Description

The LAN9210 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 LAN9210 is fully IEEE 802.3 10BASE-T and 802.3u 100BASE-TX compliant, and supports HP

Auto-MDIX.

The LAN9210 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 with a

16-bit external bus. The integrated checksum offload engines enable the automatic generation of the

16-bit checksum for received and transmitted Ethernet frames, offloading the task from the CPU. The

LAN9210 also includes large transmit and receive data FIFOs to accommodate high latency

applications. In addition, the LAN9210 memory buffer architecture allows highly efficient use of memory

resources by optimizing packet granularity.

Applications

The LAN9210 is well suited for many medium-performance embedded applications, including:

Printers, kiosks, POS terminals and security systems

Audio distribution systems

General embedded systems

Basic cable, satellite and IP set-top boxes

Voice-over-IP solutions

The LAN9210 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 LAN9210 can

automatically generate flow control packets to the remote node, or assert back-pressure on the remote

node by generating network collisions.

The LAN9210 supports numerous power management and wakeup features. The LAN9210 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.
