Figure 1-1 summarizes a system configuration of the LAN89218 in a typical embedded environment.

1.1

Compatibility with LAN911x and LAN921x Device Families

The LAN89218 is driver-, register-, and footprint-compatible with previous generation LAN911x and LAN921x device

families. Drivers written for these products will work with the LAN89218. However, when migrating from the LAN911x

family, in order to support HP Auto-MDIX, other components such as the magnetics and the passive components

around the magnetics need to change. Supporting these changes does require a minor PCB change. Refer to the

Microchip website for additional application details.
