GENERAL DESCRIPTION
PCnet-Mobile (Am79C930) is the first in a series of mo-
bile 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 pro-
tocols 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 sup-
ports 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 power-
sensitive applications.
The Am79C930 device provides users with a media ac-
cess controller that has flexibility (i.e., bus interface,
protocol, and physical layer support) to allow the
design of multiple products using a single device. By
having all the necessary MAC functions on a single
chip, users only need to add memory and the physical
layer in order to deliver a fully functional wireless LAN
connection.
