General Description
The DA14583 integrated circuit has a fully integrated radio transceiver and baseband processor for Bluetooth® low energy. It can be used as a standalone application processor or as a data pump in hosted systems.

The DA14583 supports a flexible memory architecture, including 1 Mbit of Flash memory, for storing Bluetooth profiles and custom application code, which can be updated over the air (OTA). The qualified Bluetooth low energy protocol stack is stored in a dedicated ROM. All software runs on the ARM® Cortex®-M0 processor via a simple scheduler.

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 transceiver interfaces directly to the antenna and is fully compliant with the Bluetooth 4.2 standard.

The DA14583 has dedicated hardware for the Link Layer implementation of Bluetooth low energy and interface controllers for enhanced connectivity capabilities.
