Application
802.11 b/g/n AP/Router
•
NAS
Dual Band Concurrent Router
• iNIC
The
RT3052
SOC
combines
Ralink’s
802.11n
draft
compliant
2T2R
MAC/BBP/RF,
a
high
performance
384MHz
MIPS24KEc
CPU
core,
5-port
integrated
10/100
Ethernet
switch/PHY,
an
USB
OTG
and
a
Gigabit
Ethernet
MAC.
With
the
RT3052,
there
are
very
few
external
components
required
for
2.4GHz
11n
wireless
products.
The
RT3052
employs
Ralink
2nd generation 11n technologies for longer range and
better throughput.
The embedded high performance
CPU
can
process
advanced
applications
effortlessly,
such as routing, security and VOIP. The
USB port can
be
configured
to
access
external
storage
for
Digital
Home
applications.
In
addition,
the
RT3052
has
rich
hardware
interfaces
(SPI/I2S/I2C/UART/GMAC)
to
enable many possible applications.
