Dialog DA14585-00000AT2 Smallest, lowest power and most integrated bluetooth 5 soc Datasheet

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.

development platform for all SmartBond devices, which contains:
■ S
martSnippets Toolbox: A tool suite covering all software developer needs, including power
profiling, FLASH or OTP programming and testing
