NJU6350
SERIAL I/O REAL TIME CLOCK
s
GENERAL DESCRIPTION
The
NJU6350
is a serial I/O Real Time Clock suitable for
4 bits micro-processor.
It contains quartz crystal oscillator, counter, shift register,
voltage regulator, voltage detector, and interface controller.
The
NJU6350
required only 3-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
NJU6350
can count accurate time data
even if the back up period.
Furthermore, the long time back up is available as the
current consumption during the back up period is less than
2碌A(chǔ).
