CYW20721

Overview

AIROC™ CYW20721 Bluetooth® and Bluetooth® LE System on Chip

The CYW20721 is a Bluetooth® 5.1-compliant, stand-alone baseband processor with an integrated 2.4 GHz transceiver with Bluetooth® LE, EDR and BR. The device is intended for use in audio, IoT, sensors (medical, home, security, and so forth) and human interface device (HID) applications. Manufactured using an advanced 40 nm CMOS low-power fabrication process, the CYW20721 employs high level of integration to reduce external components, thereby minimizing application footprint and costs.
