DA14531
Final Ultra Low Power Bluetooth 5.1 SoC General Description
The DA14531 is an ultra-low power SoC integrating a 2.4 GHz transceiver and an Arm® Cortex-M0+
microcontroller with a RAM of 48 kB and a One-Time Programmable (OTP) memory of 32 kB. 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® low energy stack is fully
compliant with the Bluetooth® Low Energy 5.1 standard.
The DA14531 has dedicated hardware for the Link Layer implementation of BLE and interface
controllers for enhanced connectivity capabilities.
The BLE 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 disposables, wireless sensor nodes, beacons, proximity tags and trackers,
smart HID devices (stylus, keyboards, mice, and trackpads), toys, and medical and industrial
applications. Key Features
