1 Overview
RMB 10 块的高性能 BDS/GNSS 全星座 SoC 芯片
片上集成射频前端，数字基带处理器，32 位的 RISC CPU，电源管理功能。
AT6558 支持多种卫星导航系统，包括中国的 BDS（北斗卫星导航系统），美国的 GPS，俄罗斯的 GLONASS，欧盟的 GALILEO，日本的 QZSS 以及卫星增强系统 SBAS（WAAS，EGNOS，GAGAN，MSAS）。其是一款真正意义的六合一多模卫星导航单芯片，可以同时接收六个卫星导航系统的 GNSS 信号，并且实现联合定位、导航与授时
- 2.7 ~ 3.6V
- BDS/GPS 双模连续运行：<23mA（@3.3V）
- 待机：<10uA（@3.3V）
