I suggest France´s BEA to learn ASAP how to differentiate between a CSMU of a FDR to the one they found, from the CVR:
The drawing on the Honeywell data sheet is not correct for the "4X" (4700) series recorders. It is only correct for "1X" and "2X" models.
See this picture of the Gol 1907 FDR (which used the same recorder model as used on AF447):

Note that we know this is not the CVR because on that flight the CVR's memory module separated, while the FDR's did not.
