CYW43570KFFBGT

Product Overview

CYW43570KFFBGT is an RF transceiver SoC with integrated microcontroller from Infineon Technologies. The device combines radio communication and embedded control in one package, making it useful when the wireless protocol stack and local application processing need to sit close together. It is typically reviewed for Bluetooth Low Energy connectivity and for products such as Bluetooth Low Energy devices, beacons, sensors, wearable electronics, smart-home products and connected accessories.

For design-in or replacement, buyers should confirm 2.4 GHz ISM-band operation should be checked against the datasheet and regional settings, the orderable version is associated with a 254-TFBGA, FCBGA package, surface-mount IC package for compact RF PCB layouts. The antenna path, matching network, firmware or protocol stack, regulatory requirements and lifecycle status should also be checked against the official manufacturer documentation before production use.
