IN1356 CMOS IC OF REAL TIME WATCH WITH SERIAL INTERFACE Microcircuit IN1356 is essentially the binary-decimal watch with calendar, has the additional 56 bytes of the nonvolatile static memory and possesses the low power consumption.

Addresses and data are transferred in series via the double wire bi-directional bus.

The microcircuit is intended for count of the current time in hours, minutes and seconds, count of the week days, date, month and year.

The last day of the month is automatically adj
