... GENERAL DESCRIPTION The NJU6356 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 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 timer data is transferred to the shift register at rising edge of the CE (1) and LSB of the timer data is output to the DATA terminal. timer data in the shift register shift by synchronized at falling edge of the CLK(2) then output to the DATA terminal time-to-time. NJU6356 Hour Minute Second ...
