DA14585
Bluetooth 5.0 SoC with Audio Interface
General Description
The DA14585 is an ultra-low power SoC integrating a 2.4 GHz transceiver and an
ARM Cortex-M0®
microcontroller with 96kB of RAM and 64kB of One-Time Programmable (OTP) memory. It offers a
very fast boot time (<50ms) and supports up to 8 BLE connections. It can be used as a standalone
application processor or as a data pump in hosted systems.
The radio transceiver, the baseband processor and the qualified
Bluetooth® LE
stack is fully
compliant with the
Bluetooth® Low Energy 5.0 standard.
The DA14585 has dedicated hardware for the Link Layer implementation of
Bluetooth® Low Energy
and interface controllers for enhanced connectivity capabilities.
The
Bluetooth® Low Energy
firmware includes the L2CAP service layer protocols, Security Manager
(SM), Attribute Protocol (ATT), the Generic Attribute Profile (GATT) and the Generic Access Profile
(GAP). All profiles published by the
Bluetooth
SIG as well as custom profiles are supported.
The device is suitable for remote control units (RCU) requiring support for voice commands, wireless
sensor nodes, Bluetooth Mesh applications, fitness trackers, toys and HID devices (keyboards, mice,
etc.).
