GENERAL DESCRIPTION
PCnet-Mobile (Am79C930) is the first in a series of mobile networking products in AMD’s PCnet family. The Am79C930 device is the first single-chip wireless LAN media access controller (MAC) supporting the IEEE 802.11 (draft) standard and the Xircom Netwave™ MAC protocols. The Am79C930 device is designed to have a flexible protocol engine to allow for industry standard and proprietary protocols. Protocol firmware for Xircom Netwave and IEEE 802.11 (draft) MAC protocols are supplied by AMD. It is pin-compatible with the PCMCIA bus or the ISA (Plug and Play) bus through a pin-strapping option.

The Am79C930 device contains a PCMCIA/ISA bus interface unit (BIU), a MAC control unit, and a transceiver attachment interface (TAI). The TAI supports frequency-hopping spread spectrum, direct sequence spread spectrum, and infrared physical layer interfaces. In addition, a power down function has been incorporated to provide low standby current for powersensitive applications.
