## **SmartBond[™] DA14585** 

## **Smallest, lowest power and most integrated Bluetooth 5 SoC** 

Connected devices are constantly evolving. New generations appear that are smarter, more full featured and have longer battery lifetimes. To enable this, **SmartBond** has evolved too. The DA14585 offers designers all the benefits of the industry-leading DA14580 but with even greater flexibility to create more advanced applications from the smallest footprints and power budgets. 

As part of the Dialog SmartBond family, the DA14585 is the smallest, lowest power and most integrated Bluetooth[®] solution available. This versatile SoC is ideal for adding Bluetooth low energy to products like remote controls, proximity tags, beacons, connected medical devices and smart home nodes. It supports all Bluetooth developments up to and including Bluetooth 5 and Bluetooth low energy Mesh. Plus, with 96 kB of RAM, the DA14585 has double the memory for user applications of its predecessor to take full advantage of the standard’s features. It also includes an integrated microphone interface for voice support at low additional cost. The wide supply voltage range (0.9 –3.6 V) covering a larger choice of energy sources and gives full design flexibility. 

Like all SmartBond solutions, the DA14585 is easy to design-in and supports standalone as well as hosted applications. It is supported by a complete development environment and Dialog’s **SmartSnippets[™]** software that helps you optimize your software for power consumption.

## **Bluetooth 5.0** 

Supporting the Bluetooth 5.0 core specification, DA14585 enables new enhanced Bluetooth low energy functionality ideal for applications such as remote controls, beacons, connected sensors and innovative medical devices. Among the new features, DA14585 supports Data Packet Length Extension, Link Layer Privacy v1.2, Secure Connections, Bluetooth low energy Mesh and Efficient connectable Advertising. 

## **Audio Unit** 

The integrated Audio Unit (AU) is equipped with a Pulse-Density Modulation (PDM) interface that can be connected to up to 2 input devices (e.g. MEMS microphones) or output devices, a PulseCode modulation (PCM) controller which provides an up to 192 kHz synchronous interface to external audio devices, ISDN circuits and serial data interfaces (I2S) and a 24-bit Sample Rate Converting unit (SRC) used to convert the sampling rate of audio samples between the various interfaces. PDM and PCM functionality can be mapped to any GPIO through the user programmable pin logic. An integrated DMA controller handles all data transfers between the AU and the RAM providing the CPU with the freedom to cope with other tasks. 

## **Enhanced Memory** 

The DA14585 has a large memory capacity for user applications: 96 kB of Data RAM with retention capability, 128 kB of ROM and 64 kB of One-Time-Programmable (OTP) memory. The granularity of the RAM cells (32 kB/16 kB/16 kB/32 kB) allows retaining only the RAM needed and achieves the minimum power consumption during sleep time.

## **Wide Input Voltage** 

The DA14585 can be configured in buck or boost mode to support a multitude of power sources from zinc-air  batteries to alkaline or coin cells. Furthermore, in order to maximize the available power from zinc air or coin cell and build products with long battery lifetimes, the DA14585 is able to cold boot at 0.9 or 1.8 V respectively exploiting the full capacity of the connected battery. 

## **Compatibility** 

As part of the SmartBond family and successor of the DA1458x product family, DA14585 is fully pin-compatible with DA14580, DA14581 and DA14583 existing designs may be quickly upgraded. DA14585 is suitable for fully hosted applications without an external MCU.
