Description

The Cirrus Logic CS22210 Wireless Network Controller enables high speed, 11 Mbps digital wireless

data connectivity for wireless data connectivity for PCI, mobile, embedded systems and other cost

The CS22210 is a highly integrated single-chip PCI / USB solution for wireless networks supporting video,

audio, voice, and data traffic. The programmable controller executes Cirrus Logic’s Whitecap™2

networking protocol that provides Wi-Fi™ (802.11b) compliance as well as multimedia and quality of

service (QoS) support.

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 to11 Mbps throughput. The CS22210 is designed to support both a standard PCI 2.1 or

PCI 2.2 compliant interface or USB 1.1 compliant device interface making it an ideal choice for cost

The CS22210 utilizes state-of-the-art 0.18um CMOS process and is housed in a 208 MQFP package

designed to provide integrated low cost IEEE 802.11 standard compliant system solutions. The core is

powered at 1.8 V to reduce overall power consumption. In addition, the CS22210 supports various power

management modes for host, MAC, baseband, and radio interfaces.
