I. Overview:

The Actions ATS3015 is a highly integrated single chip solution for Bluetooth audio, targeting the wireless and stereo Bluetooth headset market, with high performance, low power consumption, low latency and low cost. The ATS3015 integrated Bluetooth controller supports the V5.0 Bluetooth specification; supports dual modes (Classic Bluetooth and Low Power Bluetooth); supports Linein mode as well as background Bluetooth mode. This solution is currently one of the main TWS gaming headset solutions.
