Hi
I believe that the Solomon SSD1963 is an LCD controller which allows interfacing to processors via a parallel interface (possibly also via SPI).
It is therefore possible to use practically any processor - the Kinetis can be interfaced very efficiently using its FlexBus.
The K70 has an internal LCD controller which doesn't require an external LCD controller like the SSD1963. It is designed to interface directly to the LCD itself and save the external controller requirement.
Regards
Mark
