We are shortage of GPIO with 5223x, any better CF family chipset?, also lot of application code and web pages developed with M52233DEMo, looking for some compatable chipset with more GPIO (80 pin will be better). thanks.

Hi

 

If you don't need high speed GPIO it is quite easy to extend using QSPI and shift registers.

 

Also the M52259, with Mini-FlexBus allows additional high-speed memory mapped IO to be added (up to 80MHz).

 

Regards
