The diagram shown in Figure 3.1, "Basic Functional Block Diagram", describes the device basic
functional blocks. The SMSC LAN91C111 is a single chip solution for embedded designs with minimal
Host and external supporting devices required to implement 10/100 Ethernet connectivity solutions.
The optional Serial EEPROM is used to store information relating to default IO offset parameters as
well as which of the Interrupt line are used by the host.
