RT3052

RT3050/52 Datasheet Preliminary 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.
