The NJU6356 series is a serial I/O real time clock suitable for 4 bits microprocessor.
NJU6356 contains quartz crystal oscillator, counter, shift register, voltage regulator, voltage detector and interface controller. The NJU6356 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 NJU6356 series can count accurate time data even if the back up period.
Furthermore, the long time back up is available as the operating current of NJU6356 during the back up period is less than 3uA(TYP).
