A Real-Time Clock (RTC) is a computer clock normally in the form of an IC and it keeps track of the current time.  It also can keep date/year data.  RTC’s have low power consumption.

These devices are found in personal computers, network servers, embedded systems as well as all electronic devices that need to keep time.

The NJU6355 series is a serial I/O real time clock suitable for 4 bits microprocessor. It contains quartz crystal oscillator,counter,shift register,voltage regulator,voltage detector and interface controller. The NJU6355 series required only 4-port of microprocessor for data transfer,and the microprocessor can receive the data at any time when the microprocessor requires. The operating voltage is as wide as 2.0V to 5.5V,consequently,the NJU6355 series can count accurate time data even if the back up period. Furthermore,the long time back up is available as the operating current during the back up period is less than 3uA

The NJU6355EM is a sERIAL I/O REAL TIME CLOCK (RTC) in an 8-emp package. It has an operating temp. rating of -30°C ~ 80°C and a date format of YY-MM-DD-dd. It feautues BCD Counts of Seconds,Minutes,Hours,Days of WeekDay,Month and Year and automatic leap year compensation until to 2099
