Overview: DA14531
Ultra-Low Power Bluetooth 5.1 SoC Datasheet 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 are fully compliant with the Bluetooth® Low Energy 5.1 standard.
The DA14531 has dedicated hardware for the Link Layer implementation of Bluetooth® LE and interface controllers for enhanced connectivity capabilities.
The Bluetooth® LE 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 DA14531-01 is optimized for peripheral only applications, provides around 25 % additional user RAM for a typical Bluetooth® LE application compared to the DA14531-00 and is pin-to-pin compatible.
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.
