Microprocessor/
Microcontroller
The SMSC LAN9221/LAN9221i 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
LAN9221/LAN9221i 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 LAN9221/LAN9221i in a
typical embedded environment.
The LAN9221/LAN9221i is a general purpose, platform independent, Ethernet controller. The
LAN9221/LAN9221i consists of four major functional blocks. The four blocks are:
