Dimitry,

You can control how many fingers work on a device via the firmware
that you load. I've asked the Zeitec guys to confirm. So, to answer
your question, if you want to build a system with a touch that
supports only 7 fingers, you can pick any part from Zeitec and give
the supplier the right firmware.

Thank you,
Bogdan Stefan
