I have a single FPC1020AP chip as shown in the picture below. The datasheet for FPC1020 says there are 19 pins, of which 15 are used. However, I cannot find the datasheet for this exact chip, which says which pad on the chip maps to which pin in the functional description. Thus I presume this must be somewhat standardized. The chip itself seems to have 34 pads and a marking in the corner, I suppose to indicate pad 1.
I contacted the manufacturer, but until now I did not get a response. I am unfamiliar with this package type, but if you would have to guess, which pad is which pin? Or is this blatently obvious and someone can point me to the specification of this package type?
