DS1306
4 of 17
32 kHz (32.768 kHz Clock Output) - The 32 kHz pin provides a 32.768 kHz output. This signal is
always present. VCCIF provides the logic high level.
X1, X2 - Connections for a standard 32.768 kHz quartz crystal. The internal oscillator is designed for
operation with a crystal having a specified load capacitance of 6 pF. For more information on crystal
selection and crystal layout considerations, please consult Application Note 58, “Crystal Considerations
with Dallas Real Time Clocks.” The DS1306 can also be driven by an external 32.768 kHz oscillator. In
this configuration, the X1 pin is connected to the external oscillator signal and the X2 pin is floated.
CLOCK, CALENDAR, AND ALARM
The time and calendar information is obtained by reading the appropriate register bytes. The real time
clock registers are illustrated in Figure 2. The time, calendar, and alarm are set or initialized by writing
the appropriate register bytes. Note that some bits are set to 0. These bits will always read 0 regardless
of how they are written. Also note that registers 12h to 1 Fh (read) and registers 92h to 9 Fh are reserved.
These registers will always read 0 regardless of how they are written. The contents of the time, calendar,
and alarm registers are in the Binary-Coded Decimal (BCD) format.
