DESCRIPTION
Microcircuit IN1363 is essentially the complete binary-decimal digital watch with calendar, alarm, timer and
possesses low power consumption. Addresses and data are transferred in series via the double wire bi-
directional bus. The microcircuit is intended for count of 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 with
fewer, than 31 days, including correction for the leap year. The watch functions in the 24 hour mode. The
microcircuit IN1363 has the built-in power control circuit, which determines the power level < 1V and forms
the bit, signaling, that information about the real time may not be correct.

All voltages are listed relative to ground. Under influence of the limit mode serviceability of the microcircuits
is not guaranteed. After plotting the limit mode serviceability is guaranteed in the limit permissible mode.
* Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the
device.
These are stress ratings only and functional operation of the device at these or any other conditions beyond
those indicated under “recommended operating conditions” is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability

1) After this time interval the first cycle signal is formed;
2) The device should internally ensure the hold time, at least, 300 nsec for the signal SDA (relative to V

of the signal SCL) in order to overlap the indeterminacy area of the signal SCL drop front
Maximum value t
