Wireless 10BT Controller
1 Introduction
The Cirrus Logic CS22250 Wireless Network Controller enables high speed, 11 Mbps digital wireless data connectivity for wireless Ethernet bridge, access points, and other broadband applications. 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 Whitecap2 networking protocol that provides Wi-Fi (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. The CS22250 is designed to provide integrated low cost IEEE 802.3 standard compliant system solutions. The controller also incorporates a high-speed parallel interface, which can be used to interface with other ASICs (eg: HNPA 2.0 Network controller) to implement a variety of other wireless LA……
