Picture 1 is record microcomputer running time counter circuit of D51602.This circuit is used to record microcomputer control running time.There are two 32-bit counter and the experienced time is counted in seconds.One is continuous work 32-bit counter and it counts the time of the microcomputer.The other is 32-bit counter of AC power supply and it counts the time of the microcomputer.Thus,we can know microcomputer work time and down time. Picture 1:Record Microcomputer Running Time Counter Circuit of D51602 3 V battery and 32.768 kHz crystals Xl are added to DS1602 and it is connected to the microcomputer via the three thread and the circuit is very simple.32-bit counter can count for 136 years continously.Ac power is off , D51602 current consumption is less than 0.5 μA.And the battery life can be up to 10 years if 50 mAh capacity of the battery can be used.
