PHY6252是一款支持BLE 5.2功能的系統級芯片（SoC），集成了低功耗的高性能多模射頻收發機，搭載32位高性能低功耗處理器，提供64K retention SRAM、可選512/256K Flash、96KB ROM以及256bit efuse，支持基于BLE的安全架構、應用和OTA在線升級。此外，芯片串行外設IO和集成的應用程序IP還能夠讓客戶以最小的BOM成本開發自己的產品。
高性能多模射頻收發機
通過硬件模塊的充分復用以最低代價實現多模數字收發機。發射機最大發射功率達到10dBm；BLE 1Mbps速率下接收機靈敏度達到-99dBm，鏈路射頻預算109dB@1Mbps；0dBm時收發功耗8.6/8mA（TX/RX）。此外創新了無需調制系數估計的相干解調（Coherent Demodulation），提供3dB的解調增益，將通信距離和抗干擾能力提高了數倍。
低功耗芯片設計
采用高效率片上電源管理、低功耗射頻前端、低功耗時鐘產生架構、振蕩器快速啟動技術等電路技術，實現低峰值功耗、低平均功耗和低休眠功耗，保證電力供應場景中設備的低功耗性能。
超低BOM成本
PHY6252擁有超高集成度，最小系統僅需1個16MHz晶振和1個常規電容，不需要額外的射頻器件和功率電感，大大降低了整體物料成本。
多樣化的應用領域
智能穿戴設備、智能家居、智能照明、智能電表、自拍器、防丟器、遙控器、手機外設、電子價簽、藍牙信標、醫療健康、智能樓宇、智慧工業。
自主知識產權全棧藍牙方案和多協議棧支持
