Infineon Technologies CYW20721 BR/EDR/BLE BLUETOOTH® 5.0 SoCs

Infineon Technologies CYW20721 BR/EDR/BLE BLUETOOTH® 5.0 System-on-Chip (SoC) modules are Bluetooth 5.0-compliant, stand-alone baseband processors with an integrated 2.4GHz transceiver, implementing Bluetooth Low Energy, EDR, and BR. These modules are manufactured using an advanced 40nm CMOS low-power fabrication process, which employs a high level of integration, reducing external components that minimize application footprint and costs. Infineon Technologies CYW20721 BR/EDR/BLE BLUETOOTH® 5.0 SoCs are ideally suited for use in audio, the Internet of Things (IoT), sensors, and human interface device (HID) applications.
