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.

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.

The Am79C930 device contains a PCMCIA/ISA bus

interface unit (BIU), a MAC control unit, and a
