32.768kHz晶体连接。内部振荡器电路设计用于 具有12.5pF额定负载电容(CL)的晶体。引脚X1是振荡器的输入 并且可以选择连接到外部32.768kHz振荡器。内部的输出 如果外部振荡器连接到引脚X1,振荡器(引脚X2)悬空。外部的 32.768kHz振荡器也可以驱动PT7C4338。在这种配置中,X1引脚是连接的 外部振荡器信号和X2引脚是浮动的。

串行时钟输入。SCL用于同步I2上的数据移动 c串行接口

串行数据输入/输出。SDA是双线式串行接口的输入/输出引脚。SDA引脚为开漏输出,需要一个外部上拉电阻

方波/输出驱动器。使能且SQWE位设为1时,SQWE输出引脚 输出四种方波频率之一(1Hz、4kHz、8kHz、32kHz)。它是开漏,需要一个外部上拉电阻。应用VCC或VBAT时工作。

电源电压。当在正常范围内施加电压时,器件完全可以接触到 数据可以写入和读取。当备用电源连接到设备并且VCC 在VPF以下,读取和写入被禁止。然而,计时功能仍在继续 不受较低输入电压的影响。
