The DA14585 integrated circuit is an optimized version of the DA14580， offering a reduced boot time and supporting up to 8 connections. It 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 device is optimized for remote control units （RCU） requiring support for voice commands and motion/gesture recognition. Its integrated Audio Unit （AU） offers easy interface for MEMS microphones over PDM， external codecs over PCM/I2S and a Sample Rate Converter unit. 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 5.0 standard. The DA14585 has dedicated hardware for the Link Layer implementation of Bluetooth Low Energy and interface controllers for enhanced connectivity capabilities.
