3.3 RT3883

The RT3883 SOC combines Ralink's 802.11n draft compliant 3T3R MAC/BBP/RF, a high
performance 500MHz MIPS74Kec CPU core, a Gigabit Ethernet MAC, and a USB Host/Device.
With the RT3883, there are very few external components required for 2.4/5GHz 11n wireless
products. The RT3883 employs Ralink 2nd generation 11n technologies for longer range and
better throughput.
applications effortlessly, such as WI-FI data processing without overloading the host processor.
In addition, the RT3883 has rich hardware interfaces (SPI/ I2S/ I2C/ PCM/ UART/ USB/ PCI/ PCIe/
RGMII/ MII) to enable many possible applications.
