SmartBond™ DA14680
The most integrated and flexible Bluetooth® low energy SoC
Create next-generation Bluetooth low energy solutions without compromising on
functionality or battery lifetime, thanks to Dialog’s SmartBond DA14680.
It’s the world’s first single-chip solution for wearables, smart home and other rechargeable devices.
This highly integrated solution supports the full Bluetooth 4.2 features. As a SmartBond device,
it offers the highest performance, lowest power consumption and smallest footprint. Delivering
processing capacity when you need it and saving power when you don’t, it can manage multi-sensor
arrays and enable always-on sensing. Plus our SmartSnippets™ tooling helps you optimize your
software for power consumption.
The DA14680 includes Flash memory, offers unlimited execution space and enables over-the-air
updates. With an integrated Power Management Unit comprising system power rails, a battery
charger and a fuel gauge, it supports rechargeable batteries natively and can power a complete
sensor-based system. Meanwhile, a dedicated hardware crypto engine delivers banking-level
security (including Apple HomeKit support) with end-to-end encryption to keep personal data safe.

Power Management
There are 3 power rails that can
be used to supply external devices
namely Vsys, Vflash and Vext. There
are also internal rails used for the
core and the radio (Vcore , Vradio). All
of the rails are supplied by a normal
LDO, a Retention LDO or one of the
outputs of the Single Inductance
Multiple Output (SIMO) DCDC
converter. When the SoC is active,
the DCDC is enabled. When the SoC
is in sleep mode, then the Retention
LDOs are supplying the rails.

vice-versa.

The driving capability of the various rails is depicted in the figure: light blue for active, dark blue
for sleep. LDOs as well as DCDC outputs can be switched on/off depending on the application’s
requirements. A flexible Constant Current / Constant Voltage (CC/CV) charger supplying currents
from 200 uA to 400 mA allows for native re-chargeable batteries support. Finally, a State-of-Charge
engine, monitors the remaining capacitance of the battery when the system is active. The Power
Management Unit reduces Bill of Material and enables full control of the power budget of the final
product.

Application CPU
The ARM M0™ CPU is equipped with a configurable 16 kB cache which can operate in direct,
two-way or four-way associative mode. Moreover, the cache line size can be programed to be 8,
16 or 32 bytes. The SoC allows execution directly from the integrated FLASH (8 Mb) or the OTP.
There are 2 separate buses, one serving the code execution path (CPU, FLASH) and another which
serves data storage (DMA, Peripherals) hence eliminating latencies in application execution. The
CPU can be clocked by the XTAL16 crystal oscillator (16 MHz), or by a low-power internal PLL
which boosts the frequency to 96 MHz, enabling complex applications or algorithms without the use
of an external or dedicated MCU.
System Booting
The DA14680 supports booting from a serial interface or from a non-volatile memory (FLASH or
OTP). It also comes with a pre-defined header residing in OTP which contains configuration flags
but also trim values and preferred settings programmed during silicon manufacturing and/or final
product testing by the customer. Booting latency might vary from 15 ms (NVM booting path) to
some hundreds of ms (serial path) depending on the serial interface used and the speed/size of the
booting transaction.
Sleep Modes
The DA14680 comprises multiple power domains which are powered by the Vcore rail and can be
switched on or off by software. This flexibility combined with manipulating clocks and retainable
RAM cells, leads to the three different sleep modes of the system: Extended Sleep, Deep Sleep and
Hibernation. The first mode is used between Bluetooth low energy activities, the second is a clock-
less mode with RAM retained (used to store pairing parameters) while the third is a clock-less mode
with all RAM off, achieving the minimum current dissipation.
Software and Tools
The DA14680 is supported by Dialog SmartSnippets Studio, a royalty-free software development
platform for all SmartBond devices, which contains:
■ SmartSnippets Toolbox: A tool suite covering all software developer needs, including power
profiling, FLASH or OTP programming and testing
■ SmartSnippets IDE: An Eclipse CDT based IDE pre-configured plugins allowing easy out of
the box set-up of the build/debug environment
■ SmartSnippets DA1468x Software Development Kit and Documentation
