DESCRIPTION
IN1307 is essentially the binary decimal digital watch with a calendar, it has the additional
56 bytes of the power self-sufficient static RAM and possesses the low power consumption. The
addresses and data are applied consecutively via the two-wire bi-directional bus. The microcircuit
is intended for count of the real time in hours, minutes and seconds, count of week days, date,
month and year. The last day of the month is automatically adjusted for the months of less, than 31
days, including correction for the leap year. The watches function in the 24-hour format or in the
12-hour format with the AM / PM-indicator. IN1307 has the built-in power supply control circuit,
which determines the supply disruption and automatically switches over the device into the battery
mode.

After this time interval the first time cycle signal is formed;
Device should internally ensure the hold time, at least, 300 nsec for the signal SDA (relative to VIHMIN of
signal SCL) in order to overlap the indeterminancy area of the fall signal of SCL.
maximum value tHD:DAT should be definite in that case, if the device does not increase duration of the low
status (tLOW) of signal SCL.

OSCILLATOR CIRCUIT
IN1307 uses an external 32.768kHz crystal. The oscillator circuit does not require any exter-
nal resistors or capacitors to operate. Table specifies several crystal parameters for the external
crystal.

page.
CLOCK ACCURACY
The accuracy of the clock is dependent upon the accuracy of the crystal and the accuracy of
the match between the capacitive load of the oscillator circuit and the capacitive load for which the
crystal was trimmed. Additional error will be added by crystal frequency drift caused by tempera-
ture shifts. Externalcircuit noise coupled into the oscillator.

Figure shows a functional schematic of the oscillator circuit. If using a crystal with the specified
characteristics, the startup time is usually less than one second.
