DS1306
9 of 17
The SDI and SDO pins are the serial data input and output pins for the DS1306, respectively. The CE
input is used to initiate and terminate a data transfer.
The SCLK pin is used to synchronize data
movement between the master (microcontroller) and the slave (DS1306) devices.
The shift clock (SCLK), which is generated by the microcontroller, is active only during address and data
transfer to any device on the SPI bus.
The inactive clock polarity is programmable in some
microcontrollers. The DS1306 determines on the clock polarity by sampling SCLK when CE becomes
active. Therefore either SCLK polarity can be accommodated. Input data (SDI) is latched on the internal
strobe edge and output data (SDO) is shifted out on the shift edge (see Table 3 and Figure 5). There is
one clock for each bit transferred. Address and data bits are transferred in-groups of eight.

* CPOL is the “Clock Polarity” bit that is set in the control register of the microcontroller.
** SDO remains at High Z until 8 bits of data are ready to be shifted out during a read.
NOTE:
CPHA bit polarity in the processor (if applicable) may need to be set accordingly.
