Fanuc makes roboters and CNC machines, so motor driver or servo 
controller seems to be likely. The only manufacturer known to me using 
the MB prefix is Fujitsu Microelectronics, they make microcontrollers 
and also do ASIC jobs, so this could fit as well. So it might be a 
Fujitsu chip, probably w/ a custom ROM or perhaps a full blown ASIC for 
Fanuc. Good luck finding anything on the Fujitsu website(s) - they have 
several and search functions were rather spotty last I looked.
