Just add sensors!
The SmartBond DA14680 includes everything you need to create context-aware, multi-sensor wearables. Just add the relevant sensors for your specific application.
The lowest power consumption
All the hardware in the DA14680 is designed to save you power. That includes the 30 μA / MHz ARM Cortex-M0 application processor, integrated sensor hub functionality and hardware crypto engine. With an integrated PMU including system power rails, a battery charger and fuel gauge, it supports rechargeable Li-Ion and Li-Polymer batteries natively and can power a complete wearable system. Plus our SmartSnippets™ tooling helps you optimize your software to reduce power consumption even further and speed up your time to market.
Processing power on demand
The DA14680 delivers outstanding application processor performance – up to an impressive 84 DMIPS. What’s more, its unique FlexPower feature ensures that performance is there when you need it and saves you power when you don’t. You can dynamically control the processor speed through software, from 0 to 96 MHz to match your application’s requirements.
For maximum design freedom, the DA14680 can execute code from Flash or one-time programmable (OTP) memory. Flash offers the potential for unlimited execution space and over-the-air (OTA) updates, while OTP provides a simple cost-down path.
The dedicated hardware encryption engine includes support for hashing functions (SHA-512), symmetric (AES-256) and asymmetric cryptography algorithms (ECC) and a true random number generator. It delivers banking-level security with end-to-end encryption to keep personal data safe – while reducing power consumption.
