Atmosic chooses CEVA for battery-free Bluetooth 5 IoT chip

By Nick Flaherty www.flaherty.co.uk

Chip designer Atmosic Technologies is to use the RivieraWaves Bluetooth 5 Low Energy (RW-BLE5)  IP core for a range of low power chips that do not need batteries for wireless communications in the Internet of Things (IoT).
 
The Atmosic M2 and M3 Series IoT systems-on-chip (SoCs) target a range of end markets for low power wireless applications, including wearables, personal and asset trackers, beacons, remotes, keyboards, mice, and more.

To achieve battery free operation, Atmosic developed a number of innovative RF CMOS technologies, including Lowest Power Radio, On-demand Wake-up, and Controlled Energy Harvesting. The On-demand Wake-up reduces the power consumption so that energy harvesting becomes a viable power source. The Atmosic M3 Series Bluetooth 5 SoC expands on the M2 with Controlled Energy Harvesting, which can provide forever battery life or even eliminate the need for battery power. The M2 and M3 Series will be demonstrated during the upcoming Consumer Electronics Show (CES) in Las Vegas.

"Our 'Forever Connected, Anywhere' M2 and M3 Series platforms showcase just what can be achieved with Bluetooth low-energy, connected devices," said David Su, CEO of Atmosic. "Our low power architecture integrates the RW-BLE5 Software and Link Layer IP from CEVA, a perfect complement to our power saving and energy harvesting RF CMOS innovations, to help achieve our vision of a battery-free IoT future."

"We are excited by the immense potential of battery-free, Bluetooth-connected IoT," said Aviv Malinovitch, vice president and general manager of the Connectivity Business Unit at CEVA. "We look forward to seeing the Atmosic M2 and M3 SoCs deployed in all manner of innovative products in the market."

The RivieraWaves Bluetooth IP platforms support both Bluetooth LE and Bluetooth dual mode connectivity. Each platform consists of a hardware baseband controller with a software protocol stack. A flexible radio interface allows the platforms to be deployed with either RivieraWaves RF or various partners' RF IP, enabling optimal selection of foundry and process node. All Bluetooth 5 features are supported, including LE 2Mbps data rate, Long Range and LE Advertising Extension.
