CYW4354
1.2 Features
The CYW4354 supports the following features:
■ IEEE 802.11a/b/g/n/ac dual-band 2x2 MIMO radio with virtual-simultaneous dual-band operation
■ Bluetooth v4.1 + EDR with integrated Class 1 PA
■ Concurrent Bluetooth, FM (RX) RDS/RBDS, and WLAN operation
■ On-chip WLAN driver execution capable of supporting IEEE 802.11 functionality
■ Single- and dual-antenna support
❐ Single antenna with shared LNA
❐ Simultaneous BT/WLAN receive with single antenna
■ WLAN host interface options:
❐ SDIO v3.0 (1-bit/4-bit)—up to 208 MHz clock rate in SDR104 mode
❐ HSIC (USB device interface for short distance on-board applications)
