DA14586
Smallest, lowest power and most integrated
Bluetooth 5 SoC with integrated Flash
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
DA14586 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 DA14586 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 2 Mb of Flash memory and 96 kB of RAM, the DA14586 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.
Like all SmartBond solutions, the DA14586 is easy to design-in and supports standalone as well
as hosted applications. It is supported by a complete development environment and Dialog’s

software that helps you optimize your software for power consumption.

Bluetooth 5.0
Supporting the Bluetooth 5.0 core specification, DA14586 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, DA14586 supports Data Packet Length
Extension, Link Layer Privacy v1.2, Secure Connections, Bluetooth low energy Mesh and Efficient
connectable Advertising.
Audio Processing 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 Pulse-
Code 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 DA14586 has a large memory capacity for user applications: 2 Mb of FLASH memory, 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 the sleep state.
Compatibility
www.dialog-semiconductor.com/bluetoothlowenergy
As part of the SmartBond family and successor of the DA1458x product family, DA14586 is fully
pin-compatible with DA14580, DA14581 and DA14583 existing designs may be quickly upgraded.
DA14586 is suitable for fully hosted applications without an external MCU.
