General description
The DA14583 integrated circuit has a fully integrated radio transceiver and baseband processor for Bluetooth® Smart. 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 Smart protocol stack is stored in a dedicated ROM. All software runs on the ARM® Cortex®-M0 processor via a simple scheduler.

The Bluetooth Smart 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 4.1 standard.

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