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.
