This chip's mark is 5790BCPZ #1337 00916

And when the pin of reset is active, the voltage of some pins is bellow:

pin1:6.0mv

pin2:   5.02v

pin4:3.3V

pin16: -0.5mv

pin20: 16.3mv

pin24:  5.3mv

 

in the same situation, the voltage of another one is bellow

pin1:0mv

pin2:   5.02v

pin4:3.3V

pin16: 0mv

pin20: 0mv

pin24:  0mv

 

Is there any reason for the working out of the first one, can it be saved.Is there something i can do to reuse the chip?Thanks!
