Latest Bluetooth SoC offers integration and flexibility

SmartBond DA14681, an integrated single chip solution from Dialog Semiconductor, is claimed to provide connectivity for rechargeable devices, including wearables, smart home and other IoT devices.

The SmartBond device is said to be capable of delivering high power processing up to 96MHz from its ARM Cortex M0 processor and saving power by consuming less than 1µA when in standby. It is therefore suitable for managing multi-sensor arrays and it enables always-on sensing.

According to the company, the solution supports the latest Bluetooth 4.2 standard, and its integrated power management unit provides three independent power rails to supply external system components, in addition to an on-chip charger and fuel gauge, allowing DA14681 to recharge batteries over a USB interface. It is said to be capable of powering a complete IoT system without the need for additional external power management circuitry.

In addition to the DA14680’s functionalities, the DA14681 is said to offer 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. It can execute code from an external flash or OTP memory for maximum design freedom, with expandable execution space for applications.

To complete the package, Dialog has designed the SoC to feature banking-level security with a dedicated hardware crypto engine to keep personal data safe and enable end-to-end application encryption.
