| www..com DR A FT RT3052 802.11n Wireless Single Chip AP/Router SoC Highly Integrated with MAC, BB, RF, FE Switch, and PHY - Cost reduction to current 11n solutions - Intelligent NIC (iNIC) o oads the 802.11n wireless operations for the host system Overview 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, a 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's 2nd generation 11n technologies for longer range and better throughput. The embedded high performance CPU can process advanced applications e ortlessly, such as routing, security and VoIP. The USB port can be con gured to access external storage for Digital Home applications. In addition, the RT3052 has rich hardware interfaces (SPI/PCM/I2S/I2C/UART/GDMA) to enable many possible applications.
