NJU6355

SERIAL I/O REAL TIME CLOCK

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).
