Product description

The ATS300X is a highly integrated single chip Bluetooth audio solution. Aimed at the Bluetooth headset and earphone market, it meets market demand with high performance, low cost and low power consumption.

Uses RISC32 core architecture. Large memory capacity is embedded to meet different Bluetooth applications. ATS300X supports decoding Bluetooth A2DP audio while loading sound effects, Bluetooth hands-free calling, microphone AEC, noise reduction.

Integrated Bluetooth controller supports V5.0, compatible with V4.2/V4.2 LE/V4.0/V3.1/V2.1 Bluetooth specification, supports dual mode (BR/EDR + Low Energy Controller). links in BR/EDR and LE can be activated simultaneously.

A special approach to power optimisation is particularly suitable for various application scenarios, including sniffing, Bluetooth idle, Bluetooth play and recall modes. The embedded PMU supports power optimisation and has a long battery life.
