PHY6252是一款支持BLE 5.2功能的系统级芯片（SoC），集成了低功耗的高性能多模射频收发机，搭载32位高性能低功耗处理器，提供64K retention SRAM、可选512/256K Flash、96KB ROM以及256bit efuse，支持基于BLE的安全架构、应用和OTA在线升级。此外，芯片串行外设IO和集成的应用程序IP还能够让客户以最小的BOM成本开发自己的产品。
高性能多模射频收发机
通过硬件模块的充分复用以最低代价实现多模数字收发机。发射机最大发射功率达到10dBm；BLE 1Mbps速率下接收机灵敏度达到-99dBm，链路射频预算109dB@1Mbps；0dBm时收发功耗8.6/8mA（TX/RX）。此外创新了无需调制系数估计的相干解调（Coherent Demodulation），提供3dB的解调增益，将通信距离和抗干扰能力提高了数倍。
低功耗芯片设计
采用高效率片上电源管理、低功耗射频前端、低功耗时钟产生架构、振荡器快速启动技术等电路技术，实现低峰值功耗、低平均功耗和低休眠功耗，保证电力供应场景中设备的低功耗性能。
超低BOM成本
PHY6252拥有超高集成度，最小系统仅需1个16MHz晶振和1个常规电容，不需要额外的射频器件和功率电感，大大降低了整体物料成本。
多样化的应用领域
智能穿戴设备、智能家居、智能照明、智能电表、自拍器、防丢器、遥控器、手机外设、电子价签、蓝牙信标、医疗健康、智能楼宇、智慧工业。
自主知识产权全栈蓝牙方案和多协议栈支持
