Cypress: Bluetooth MCUs deliver mesh networking with ubiquitous smartphone connectivity

Cypress Semiconductor announced it is sampling two low-power, dual-mode Bluetooth 5.0 and Bluetooth Low Energy microcontrollers that include support for Bluetooth mesh networking for the Internet of Things. 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 solutions 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 Serial Port Profile (SPP) protocol connections and Bluetooth mesh connections simultaneously. The CYW20820 offers the same features and integrates a power amplifier with up to 10dBm 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 Arm Cortex-M4 core enables 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 MCU is 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.

The CYW20819 and CYW20820 MCUs are supported by Cypress’ ModusToolbox development tools, which provide sample code and applications for Bluetooth mesh and sensor kits. Cypress also offers the CYW20719, CYW20706, and CYW20735 BLE solutions and the CYW43438 and CYW43570 Wi-Fi and Bluetooth combo solutions, delivering fully compliant Bluetooth mesh for devices and Wi-Fi connected smart homes.
