SmartBond™ DA14681 The most integrated and flexible Bluetooth® low energy SoC with expandable memory execution space Create next-generation Bluetooth low energy solutions without compromising on functionality or battery lifetime, thanks to Dialog’s SmartBond DA14681. 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. 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.

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. 4.7µF The normal LDOs are used while 10µF powering up the system or during transitions from active to sleep and vice-versa. VDD1V8 75mA/3mA V14 Vradio Vext VDD1V8P 10µF 75mA/3mA 10µF 0.47µH 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. www.dialog-semiconductor.com/bluetoothlowenergy 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 for eXecute In Place (XIP) operation directly from the QSPI FLASH (up to 32 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 DA14681 supports booting from a serial interface or from a non-volatile memory (QSPI 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 DA14681 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 clockless 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 DA14681 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 www.dialog-semiconductor.com/bluetoothlowenergy Specification Parameters Parameter Description Conditions Min VBAT Supply voltage Recommended operating condition 1.7 IBAT_IDLE Supply current CPU is idle (WFI), DCDC on, VBAT=3V 0.4 IBAT_RUN_16MHz Supply current CPU executes code from RAM, DCDC on, peripherals on, VBAT=3V IBAT_RUN_96MHz Supply current IBAT_EXT_SLP Typ Max Unit 4.75 V 0.6 1 mA 1.2 1.4 1.9 mA CPU executes code from RAM, DCDC on, peripherals on, VBAT=3V 5.7 6.2 6.9 mA Supply current Cache (16kB) and Data (32kB) retained.
