Block Diagram

The SMSC LAN9211 integrated 10/100 MAC/PHY controller is a peripheral chip that performs the

function of translating parallel data from a host controller into Ethernet packets. The LAN9211 Ethernet

MAC/PHY controller is designed and optimized to function in an embedded environment. All

communication is performed with programmed I/O transactions using the simple SRAM-like host

interface bus.

The diagram shown above, describes a typical system configuration of the LAN9211 in a typical

embedded environment.

The LAN9211 is a general purpose, platform independent, Ethernet controller. The LAN9211 consists

of four major functional blocks. The four blocks are:

10/100 Ethernet PHY

10/100 Ethernet MAC

RX/TX FIFOs

Host Bus Interface (HBI)
