CYW43570
1.2 Features
The CYW43570 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 and WLAN operation
■ On-chip WLAN driver execution capable of supporting IEEE 802.11 functionality
■ WLAN host interface, PCIe 2.0 (Wi-Fi), is compatible with Gen2 but the interface speed is up to Gen1 only.
■ BT host digital interface (can be used concurrently with above interfaces):
❐ UART (up to 4 Mbps)
■ BT supports full-speed USB 2.0-compliant interface
■ Enhanced coexistence support, ability to coordinate BT SCO transmissions around WLAN receives
■ HCI high-speed UART (H4, H4+, and H5) transport (interface capable, but not currently supported)
■ Wideband speech support (16 bit linear data, MSB first, left justified at 4K samples/s for transparent air coding, both through I2S
and PCM interface). (Interface capable, but not currently supported)
