SmartBond™ DA14682 and DA14683

Single-chip high-security Bluetooth 5 solution with Expandable Memory

Dialog Semiconductor DA14683 plain USB board

The SmartBond DA14682 and DA14683 are the world’s first single-chip solutions for Smart Home, Industrial and wearable devices that meets 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. As part of our SmartBond range, both SoCs offer industry-leading performance from the lowest power consumption and smallest footprint. Their flexible architecture ensures plenty of processing capacity when you need it while saving power when you don’t. 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. Specifically, 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 you to benefit from over-the-air updates. To further simplify your development, our SmartSnippetsTM software and versatile Hardware Development Kits help you optimize your software for power consumption.
