描述
The DA14582 integrated circuit has a fully integrated radio transceiver, baseband processor for Bluetooth® low energy, and includes an audio CODEC.
The DA14582 is optimized for remote control units (RCU) requiring support for voice commands and motion/gesture recognition. Its integrated analog wide band audio CODEC provides native support for analog microphones thereby reducing the total number of components of the system while its optimized package enables designs using single-layer FR1 PCBs furthermore contributing to the reduction of the cost of the system.
The DA14582 supports a flexible memory architecture 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.
