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。

+3V电池输入。任何标准3V锂电池或其他能源的备用电源输入来源。电池电压必须保持在最小和最大极限之间操作。如果不需要备用电源，VBAT必须接地。UL承认要确保使用锂电池时防止反向充电

地面。DC电源通过这些引脚提供给器件。VCC是主要的能源输入。当在正常范围内施加电压时，器件完全可以访问，数据也可以写了又看。当备用电源连接到设备且VCC低于VPF时，读取并且禁止写入。然而，计时功能不受下限的影响输入电压。
