IN1363 CMOS LIS OF REAL TIME WATCH WITH SERIAL INTERFACE 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. Functions and Features  count of seconds, minutes, hours, week days, date, months and years with consideration of leap years (until 2100);  400 kHz, double wire serial interface;  programmed orthogonal output signal;  function programming of alarm, timer and interruption;  automatic determination of the supply voltage drop;  consumption current of less, than 450 nA with supply of 2V with the operating oscillator;  operating temperature range: -40С – 85С. tructural Diagram IN1363 I N TEGRAL 1 1 page IN1363 12 pF. IN1363 can operate from the external oscillator with the frequency 32.768 kHz. With this configuration the output OSCI is connected to the signal external oscillator, and OSCO is left unconnected. Watch and Calendar Acquisition of information on time and date is performed by means of reading the appropriate register bytes. Presetting and time and calendar initialization is performed by means of the appropriate bytes. Information, contained in the time, calendar and alarm registers, is essentially the binary-decimal code. Bit 7 of register 2 is essentially the indication bit of the supply level decrease. < 1V (VL). When this bit = “1” , this signifies, that the supply voltage was below the norm, and the information on the current time may be unreliable. When switching power supply on, all register bits are preset to "0", with the exception of bits FE, VL, TD1, TD0, TESTC and AE, which are preset to "1". When applying the signal “START” on the double wire bus, the current time transfer occurs from the counters to the auxiliary set of registers. The data on time are read out from these auxiliary registers, while the watch continue to operate. This eliminates the necessity in the repeated reading in case of updating the basic registers in the access process.
