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 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 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.
