ATS2853P2

ATS2853P2 采用 CPU + DSP 双核架构。嵌入大容量 RAM 以满足不同的蓝牙应用，并支持蓝牙后台工作，同时使用传统插卡和 USB 闪存盘播放高质量音乐。
ATS2853P2 支持解码蓝牙 A2DP 音频并同时加载音效，支持带双 MIC AEC 和降噪的蓝牙免提通话。
ATS2853P2 集成蓝牙控制器，支持 V5.4 并符合 V5.3/5.2/5.0/4.2/2.1 蓝牙规范，并支持双模式（BR/EDR + 低功耗控制器）。BR/EDR 和 LE 中的链路可以同时处于活动状态。
ATS2853P2 采用特殊方法进行功率优化，特别是针对各种应用场景，包括嗅探、蓝牙空闲、蓝牙播放和通话模式。嵌入式 PMU 支持功率优化并提供长电池寿命。
ATS2853P2 的竞争优势是高音乐和通话质量、低功耗和 BOM，这为我们在高端市场的目标奠定了基础。最重要的是，
ATS2853P2 提供了真正的“ALL-IN-ONE”解决方案，使其成为高度集成和优化的蓝牙音频产品的理想选择。

乐侠可根据客户需求基于炬芯ATS2853P2提供IC，模组和完整解决方案等多种支持。
