带电池备份开关切换功能的2线接口实时时钟IC

The R2051 is a CMOS real-time clock IC connected to the CPU by two signal lines, SCL and SDA, and configured to perform serial transmission of time and calendar data to the CPU. Further, battery backup switchover circuit and a voltage detector are incorporated. The periodic interrupt circuit is conf • Minimum Timekeeping supply voltage：Typ. 0.75 V (Max. 1.00 V); VDD pin；\n• Connected to the CPU：Two signal lines (SCL and SDA), I2C-Bus Interface, 400 kHz；\n• Interrupt circuit configured to generate interrupt signals (with interrupts ranging from 0.5 seconds to 1 month) to the CPU and provided wit;
