AR8216 Product Overview
The AR8216 is Atheros’ first Ethernet switch product and
is the industry’s lowest cost, 6-port 10/100 Fast
Ethernet switch. The AR8216 is designed to support
a wide array of cost-sensitive wired and wireless
networking applications and targets mainstream 802.11n
and 802.11g wireless router and gateway platforms.
The AR8216 offers design flexibility with its 6-port
configuration consisting of five 10/100 Ethernet PHY
ports, one MII port for CPU connectivity and six
independent Media Access Controllers (MACs).
The AR8216 offers high levels of integration with the
industry’s smallest footprint achieved through a
significantly reduced number of system components in a
compact 10mm x 10mm, low-profile quad flat package
(LQFP). As a result, it delivers the industry’s lowest
RBOM, optimized design flexibility and increased cost
savings.
To provide non-blocking switching performance in all
traffic environments, the AR8216 supports an advanced
QoS architecture. This unique Atheros-designed
architecture prioritizes switch traffic for different
classes of applications, such as voice traffic for IP
phones, video traffic for multimedia and data traffic
for e-mail.
With the launch of this high-performance, low-cost
Ethernet switch
solution, Atheros now provides its networking customers
with all
of the major silicon required for complete
wire-to-wireless router
solutions
