Features
– Cost reduction to current 11n solutions
– Intelligent NIC (iNIC) ooads the 802.11n wireless operations for the host system
Overview
RT3052
802.11n Wireless Single Chip AP/Router SoC
Highly Integrated with MAC, BB, RF, FE Switch, and PHY
RT2700.qxd 11/01/07 6:00 PM Page 1
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 eortlessly, such as routing, security
and VoIP. The USB port can be congured 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.
