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.
