Ezurio BL5340 Series - Multi-Core Bluetooth 5.2 + 802.15.4 + NFC Modules
Multi-Core/Protocol to jumpstart your Bluetooth LE wireless development project
The Ezurio BL5340 Series Bluetooth Modules are the newest edition to the company’s Nordic Semiconductor-based Bluetooth LE portfolio. The BL5340 series is the most advanced, most secure and highest performing dual core MCU architecture wireless solution available.
This Ezurio series of robust, tiny Bluetooth modules feature the Nordic nRF5340 SoC. It directly targets the highest performance with the lowest power budget, with variants featuring integrated Nordic nRF21540 PA/LNA for higher TX Power applications.
Featuring Bluetooth 5.2 including Isochronous Channels and LE Audio, the BL5340 module supports next generation Bluetooth audio for stereo streaming and broadcast audio.
BL5340 MCU Cores
Extend multi-protocol capabilities of the BL5340 module thanks to the dual-core Arm® Cortex-M33 microcontrollers of the series, which enable you to run a low power core focused purely on wireless connectivity, with a second higher performance core targeted for the end application itself.
Featuring a further enhanced ARM CryptoCell-312 including trusted execution, root-of-trust, and secure key storage security features, the Ezurio BL5340 series brings out all nRF5340 hardware features and capabilities including USB access, up to +10 dBm certified for PA version (+3 dBm from SoC) transmit power, from 1.7V to 5.5V supply considerations, and a true industrial operating range of -40 to 105°C.
