AR2316

Data Sheet PRELIMINARY May 2005 AR2316 Single Chip MAC/Baseband/Radio and Processor for 2.4 GHz Wireless LANs General Description The Atheros AR2316 integrated the MAC/ baseband/radio and processor into a single chip for wireless access point and router applications. It includes a 2.4 GHz radio, MIPS 4000 processor, 802.11 MAC/baseband processor, 802.3 Ethernet MAC and MII interface, SDRAM controller, external memory interface for Flash, ROM, or RAM, PCI bus interface or a flexible local bus, UART, GPIOs, LED controls. The AR2316 implements an 802.11 MAC/ baseband processor supporting all IEEE 802.11g data rates (1 to 54 Mbps) and all IEEE 802.11b complementary key coding (CCK) data rates (1 to 11 Mbps). In Atheros Super G™ mode, AR2316 supports data rates up to 108 Mbps. Additional features include forward error correction coding at rates for 1/2, 2/3, and 3/4, signal detection, automatic gain control, frequency offset estimation, symbol timing, channel estimation, error recovery, enhanced security, and quality of service (QoS). The AR2316 performs receive and transmit filtering for IEEE 802.3 and 802.11 networks. The AR2316 is an all CMOS, highly integrated single-chip solution that supports 802.11b/g WLANs. Features ■ Integrated MIPS 4000 processor ■ 180 MHz processor frequency ■ IEEE 802.11b/g Access Point, Ad Hoc, and station functions supported ■ OFDM and CCK modulation schemes supported ■ Data rates of 1, 2, 5.5, 6, 9, 11, 12, 18, 24, 36, 48, 54 Mbps and Atheros Supe...
