Revision August 14, 2008
Application
802.11 b/g/n AP/Router
Dual Band Concurrent Router
• NAS
• iNIC
Support 16/32-bit SDR SDRAM (up-to 64M bytes)
SDRAM data [31:16] sre pins shared with GPIO
Support boot from 8/16-bit parallel NOR type Flash
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 por t 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.
