Two low-power, dual-mode Bluetooth 5.0 and Bluetooth Low Energy (BLE) microcontrollers include support for Bluetooth mesh networking for the Internet of Things (IoT). The new CYW20819 and CYW20820 MCUs each provide simultaneous Bluetooth 5.0 audio and BLE connections, delivering low-power wireless solutions that enable music and voice commands for battery-powered fitness bands, health monitoring devices, and voice remotes. Designers can also use the solution to develop low-cost, low-power Bluetooth mesh network devices that can communicate with each other—and with smartphones, tablets and voice-controlled home assistants—via simple, ubiquitous, and hub-free Bluetooth connectivity.
The CYW20819 Bluetooth/BLE MCU has the ability to maintain Secure Simple Pairing (SPP) protocol connections and Bluetooth mesh connections simultaneously. The CYW20820 offers the same features and integrates a power amplifier (PA) with up to 10 dBm output power for long-range applications up to 400 meters and whole-home coverage. This provides classic Bluetooth tablet and smartphone connections while enabling a low-power, standards-compliant mesh network for sensor-based smart home or enterprise applications. The MCUs offer up to 125 MIPS of performance with an Arm Cortex-M4 core and enable operation at 60% lower active power for connected 200ms beacons compared to current solutions—delivering up to an industry-leading 123 days of battery life from a CR2032 coin cell battery. The MCUs are ideal for wearables, sensors, remote controls, smart home lighting and medical devices, and they are forward and backward compatible for dual-mode mouse and keyboard HID applications.
Previously, users needed to be in the immediate vicinity of a Bluetooth device to control it without an added hub. Using Bluetooth mesh networking technology, combined with the high-performance integrated PA in the CYW20820, the devices within the network can communicate with each other to easily provide coverage throughout even the largest homes, allowing users to conveniently control all of the devices via apps on their smartphones, tablets, and smart-speakers.
The CYW20819 and CYW20820 MCUs are supported by Cypress’ ModusToolbox development tools, which provide sample code and applications for Bluetooth Mesh and sensor kits.

• The Cypress CYW20819EVB-02 Evaluation Kit for evaluation and development with the CYW20819 MCU will be available in March 2019
• And the Cypress Mesh Evaluation Kit (CYBT-213043-MESH), featuring a Bluetooth 5.0-qualified and regulatory certified module based on the CYW20819 MCU for development of Bluetooth mesh applications will be available in the second quarter of 2019.
Cypress’ Bluetooth solutions share a common, widely-deployed Bluetooth stack and are supported in the latest version of Cypress’ Wireless Internet Connectivity for Embedded Devices (WICED) software development kit (SDK), applied in the ModusToolbox suite, which streamlines the integration of wireless technologies for developers of smart home lighting and appliances, as well as healthcare applications.
