Espressif Licenses and Deploys CEVA Bluetooth in IoT Chip

By Nick Flaherty

Chinese chip designer Espressif Systems has licensed and deployed the RivieraWaves Bluetooth dual mode technology in its new ESP32 chip for nodes in the Internet of Things.

Espressif is headquartered in Shanghai and is developing chips for low cost wireless connectivity in a wide range of products. The new ESP32 combo chip integrates robust wireless interfaces for 802.11b/g/n Wi-Fi and CEVA’s Bluetooth 4.2 dual mode, along with GPIO for system flexibility. Designed for ultra-low power consumption, the ESP32 is aimed at mobile devices, wearable electronics and the IoT.
“The IOT is a rapidly growing set of fragmented and multi-faceted applications. The combination of Wi-Fi and Bluetooth offers the best user experience, covering a wide range of use cases." said Teo Swee Ann, CEO of Espressif Systems. "We have chosen CEVA's RivieraWaves dual mode Bluetooth IP because it allows us to address the widest possible range of applications, covering both classic and low energy connections. We are delighted with the quality and excellent technical support, which enabled us to rapidly integrate Bluetooth capabilities into Espressif's ESP32 platform."

“We are pleased to announce Espressif as a licensee for our RivieraWaves Bluetooth IP” said Aviv Malinovitch, vice president and general manager of the Connectivity Business Unit at CEVA. “The ESP32 is an impressive device which will no doubt open up Wi-Fi and Bluetooth connectivity to many new IoT products.”

The RivieraWaves Bluetooth IP platforms consist of a hardware baseband controller, plus a feature-rich software protocol stack. A flexible radio interface allows the platform to be deployed with either RivieraWaves RF or various partners’ RF IP, enabling optimal selection of foundry and process node. 

For wireless headset / earbud applications, the RivieraWaves Bluetooth 4.2 dual mode controller, modem and TSMC 40nm radio are an ideal fit and can be further augmented with a low power CEVA audio/voice DSP for noise/echo cancellation, always-on voice activation or other proprietary audio enhancements.
