Introduction

The SmartBond DA14682 and DA14683 are single-chip solutions for Smart Home, Industrial and wearable devices that meet the highest security standards. These highly integrated System-on-Chip (SoC) devices support Bluetooth 5 as well as Bluetooth mesh, and include a range of dedicated features to ensure cutting-edge security for both consumers and developers. Their flexible architecture ensures plenty of processing capacity when needed while saving power when not. It also allows the devices to manage multi-sensor arrays and enables always-on sensing. Both devices offer extensive memory capacity and differ only in their memory configuration. The DA14683 supports unlimited external Flash for maximum design flexibility while the DA14682 includes 8 Mbits of onboard Flash, making it ideal for applications with tight space constraints. Both options allow for over-the-air updates. Supporting the Bluetooth 5 core specification, DA14682 and DA14683 enable enhanced Bluetooth low energy functionality suitable for applications such as wearables, smart home applications, Bluetooth mesh. The DA14682 and DA14683 offer a complete solution for the Bluetooth mesh specification, enabling longer range, more nodes per network and a many-to-many (m:m) communication topology. The DA14682 and DA14683 support the Internet Protocol Support Profile (IPSP), allowing the exchange of IPv6 packets between devices via Bluetooth low energy transport, enabling native IPv6 support for Bluetooth low energy applications. As part of the SmartBond DA1468x product family, DA14682 and DA14683 are fully pin - and software-compatible with the popular DA14680 and DA14681.
