Infineon Technologies CYW20719 BR/EDR/BLE BLUETOOTH® 5.0 Wireless MCUs

Infineon Technologies CYW20719 BR/EDR/BLE BLUETOOTH® 5.0 Wireless MCUs are ultralow power, stand-alone baseband processors with an integrated 2.4GHz transceiver. This single chip solution features BLUETOOTH® low energy (BLE), Basic Rate (BR), and Enhanced Data Rate (EDR) for BLUETOOTH® 5.0 applications.

The CYW20719 includes support for BLE, BLE 2Mbps, EDR, SCO, and eSCO and is intended for use in audio, IoT, sensors (medical, home, security), and human interface device (HID) applications. The device is manufactured using an advanced 40nm CMOS low-power fabrication process. The CYW20719 is a highly integrated device, reducing external components and minimizing application footprint and cost.
