In order to route all the ports of this microcontroller with pitch 0.65mm, is a 4-layer PCB enough or may more layers be needed?
So far I have only used 1mm pitch BGA microcontrollers with the Kinetis MK66, and 0.8mm pitch with the RT1064. With the RT1064 it's already costing me enough to be able to route a good number of ports for a project, and that with a pitch of 0.8mm, and 4 PCB layers.
Working with PCBs with 6 layers or more, and with such small vias for that 0.65mm pitch can already make the PCB quite expensive.
