The CS22250 is a highly integrated single-chip Ethernet bridge solution for wireless networks supporting video, audio, voice, and data traffic. The programmable controller executes Cirrus Logic's WhitecapTM2 networking protocol that provides Wi-FiTM (802.11b) compliance, multimedia and a foundation for quality of service (QoS) applications, and Ethernet to wireless bridging. The device includes several high performance components including an ARM7TDMI RISC processor core, a Forward Error Correction (FEC) codec, and a wireless radio MAC supporting up to 11 Mbps throughput. The CS22250 utilizes state of the art 0.18um CMOS process and is housed in a 208 FPBGA compact package, offering low-lead inductance suitable for highly integrated radio applications. The core is powered at 1.8 V with 3.3V I/O to reduce overall power consumption. In addition, the CS22250 supports various power management modes for host, MAC, baseband, and radio interfaces. |
