CYW20721B2KUMLG

Product Overview

CYW20721B2KUMLG is an RF transceiver SoC with integrated microcontroller from Infineon Technologies. It combines the radio path and embedded control functions in one device, which helps simplify low-power wireless products with local processing needs. In a design or maintenance project, it is a candidate for Bluetooth Low Energy devices, beacons, sensors, wearable electronics, smart-home products and connected accessories.

Before design approval or replacement purchasing, check 2.4 GHz ISM-band operation; confirm the exact channel plan and regional settings in the datasheet, the 40-UFQFN Exposed Pad package or case style, surface-mount package for compact RF PCB layouts. The antenna network, protocol stack, firmware version, power profile, regulatory requirements and lifecycle status should be matched to the original design or target application.
