Dialog Semiconductor DA14681

Introducing a Bluetooth® low energy SoC with unparalleled integration and flexibility

Create next-generation Bluetooth low energy solutions without compromising functionality or battery life with the SmartBond™ DA14681, the world’s first single-chip solution in volume production that provides connectivity for rechargeable devices, including smart home and other emerging Internet of Things (IoT) devices. DA14681 delivers the highest performance, lowest power consumption, smallest footprint and lowest system cost. 

This highly integrated solution supports the latest Bluetooth 4.2 standard. An ARM® Cortex™ M0 processor, with various embedded memory options, delivers flexible processing power when you need it and saves power when you don’t, enabling the management of multi-sensor arrays and always-on sensing. Its integrated PMU can efficiently power up to three external devices in addition to an on-chip charger and fuel gauge, allowing DA14681 to recharge batteries over a USB interface, while a dedicated hardware crypto engine delivers banking-level security with end-to-end encryption to safeguard personal data.

DA14681 is the second member of a device family that includes the popular ultra-low power DA14680. In addition to DA14680’s functionalities, DA14681 delivers unparalleled flexibility offering virtually unlimited computing space to software application developers by enabling the latter to expand the size of their code execution space through a flexible external memory interface.
