Data

 

Compared with the wm9713 and wm9714 pins, we found that there is a small difference, but wm9713 has a touch screen controller (four pins) More than wm9714, And the touch screen is just right

The Controller comes with s5pv210, and these pins of wm9713 are also NC. So it should be okay. A representative sent me three wm9713 samples a few days ago and sent them to the film manufacturer tonight.

Sort out chips from work.
