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
sensitive applications
.
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 Whitecap2
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
effective standalone and embedded high-speed wireless networking products
.
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.
