Description
The Cirrus Logic CS22230 Wireless Network Controller enables high speed, 11 Mbps digital wireless connectivity for a variety of platforms including embedded systems, mobile applications, and other cost sensitive applications capable of supporting a standard Mini PCI or USB interface. The CS22230 is a highly integrated single-chip Mini 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 to 11 Mbps throughput. The CS22230 is designed to support both a standard Mini PCI 2.2 compliant interface or USB 1.1 compliant device interface, making it an ideal choice for cost effective standalone and multifunction embedded high-speed wireless networking products. The CS22230 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 CS22230 supports various power management modes for host, MAC, baseband, and radio interfaces.
