The CYW20719 complies with Bluetooth core specification version 5.0 (with LE 2 Mbps optional feature) and supports mesh networking. The SoC offers high performance and integration to help reduce external components.
The MCU powering the SoC is a 96-MHz Arm Cortex-M4 with FPU, 512 KBytes of RAM, 2 MBytes of ROM, and 1 MByte Flash. The probe-proof Flash prevents hackers from reprogramming the device to gain access to sensitive user data and inhibits competitors from doing a flash dump for reverse engineering. For additional security, the CYW20719 includes ECDH, RSA, AES and SHA/MD5 hashing functions. The device’s radio delivers a Bluetooth LE receive current (Rx) of 5.9 mA with sensitivity of -95.5 dBm and a transmit current (Tx) of 5.6 mA at 0 dBm.
The CYW20719 is supported by the CYW920719Q40EVB-01 evaluation kit and the Cypress Wireless Internet Connectivity for Embedded Devices (WICED) Studio IoT development platform.
