Cypress Semiconductor Corp. is sampling two low-power, dual-mode Bluetooth 5.0 and Bluetooth Low Energy (BLE) microcontrollers for mesh networking for the internet of things (IoT).
The CYW20819 and CYW20820 multipoint control units (MCUs) provide simultaneous Bluetooth 5.0 audio and BLE connections to deliver music and voice commands for battery-powered fitness bands, health monitoring devices and voice remotes. The MCUs can also be used to develop low-cost, low-power Bluetooth mesh network devices to communicate with each other as well as smartphones, tablets and home assistants through hub-free Bluetooth connectivity.
The CYW20819 MCU maintains 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 10 dBm output for long-range applications up to 400 m and whole-home coverage. Applications that could use the MCUs include wearables, sensors, remote controls, smart home lighting and medical devices as well as dual-mode mouse and keyboard high-intensity discharge (HID) applications.
Cypress made the announcement at Embedded World taking place Feb. 26-28 in Nuremberg, Germany.
The MCUs are supported by development tools that provide sample code and applications for mesh and sensor kits. Other Bluetooth devices and combo solutions can deliver fully compliant Bluetooth mesh for devices and Wi-Fi connected smart homes.
