RTL8181 Datasheet PDF

Realtek RTL8181

The RTL8181 208-Pin QFP (Without PCI Interface), and the RTL8181P 292Pin TFBGA, with a PCI interface for seamless connection of a PCI device. For example, an IEEE 802.11a device could be connected through this PCI interface to provide a WLAN dual mode service. The embedded processor is a Lexra LX5280 32-bit RISC CPU, with separate 8K instruction and 8K data caches.
