The DA14580 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 DA14580 supports a flexible memory architecture

　　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 DA14580 has dedicated hardware for the Link

　　Layer implementation of Bluetooth Smart and interface

　　controllers for enhanced connectivity capabilities.
