CYW43570KFFBG

Product Overview

CYW43570KFFBG is a Wi-Fi / Bluetooth RF connectivity IC from Infineon Technologies. It integrates radio and protocol-related resources for Wi-Fi/Bluetooth designs. It is commonly selected for smart appliances, IoT modules, consumer electronics, gateways and embedded Wi-Fi/Bluetooth products.

For design-in, continuation sourcing or repair work, engineers should review RF matching, antenna layout, interface timing, supply filtering and firmware compatibility. The selected orderable code should also be checked for package footprint, firmware or stack support, RF band, regulatory requirements and lifecycle status before approval.
