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.

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 VIHMIN
of the signal SCL) in order to overlap the indeterminacy area of the signal SCL drop front
Maximum value tHD:DAT should be definite in that case, if the device does not increase duration of the
low condition (tLOW) of the signal SCL
