Product Brief

RT3052F

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.
