Single-chip wireless combo integrates a 2.4 GHz IEEE 802.11b/g/n MAC, baseband, and radio with Bluetooth 4.1 support. The WLAN interface supports SDIO v2.0, including high-speed 4-bit operation up to 200 Mbps with a 50 MHz bus clock. Bluetooth host connectivity uses a high-speed UART up to 4 Mbps and supports PCM or I2S audio. The device operates from a 3.0 V to 4.8 V battery supply and supports WLBGA and WLCSP package options for compact portable designs.
