sGENERAL DESCRIPTION
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(TYP).
