SmartBond™ DA1468x Product Family

Bluetooth® low energy SoCs with unparalleled

integration and flexibility
Create next-generation Bluetooth low energy solutions without compromising functionality
or battery life with the SmartBond DA1468x family, the world’s first single-chip solution in
volume production that provides connectivity for rechargeable devices, including wearables,
smart home and other emerging Internet of Things (IoT) devices. DA14680 and DA14681
deliver 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 the SoC 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.

DA14680 and DA14681
The lowest power consumption
All the hardware in this product range 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 Power Management Unit 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 and DA14681 deliver 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 32 kHz to 96 MHz to match your
application’s requirements.

Flexible memory for complete design freedom

For maximum design freedom, the DA14680 and DA14681 can respectively execute code
from internal or external 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.

Maximum security
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.
