SoC supports Bluetooth mesh networking for smart home applications

Mouser now stocks the CYW20719 dual-mode Bluetooth wireless microcontroller from Cypress Semiconductor. Optimized for IoT applications, the device is an ultra-low-power microcontroller device that complies with Bluetooth core specification version 5.0 (with LE 2Mbps optional feature) with support for mesh networking. Produced using an advanced 40nm CMOS low-power fabrication process, this SoC employs a high level of performance and integration to help decrease external components while reducing the footprint and overall cost of the application. The microcontroller subsystem of the device consists of a 96MHz Arm Cortex-M4 microcontroller with FPU, 512KBytes of RAM, 2MBytes of ROM (containing the stack and drivers), and 1MByte of probe-proof flash memory. The flash, once programmed, not only stops hackers from reprogramming the device to gain access to sensitive information but also restrains competitors from doing a flash dump to reverse engineer the firmware IP. For extra security, the device also has multiple security functions — such as ECDH, RSA, AES and SHA/MD5 hashing functions — as well as a hardware accelerator to give best-in-class encryption for Bluetooth. The device is supported by the CYW920719Q40EVB-01 evaluation kit and the Cypress WICED Studio IoT development platform, which provides all the application programming interfaces, code snippets, and demo applications to speed the development process.
