Also, I should have mentioned that I want to use FSMC.

This isn't a multiplexed device?

http://www.issi.com/pdf/61-64WV51216.pdf You'd need to set the STM32 up for PSRAM, with the byte lanes. Check the schematics provided for the STM3210E board http://www.st.com/stonline/books/pdf/docs/14220.pdf -Clive

Thanks for your answer. 

The evaluation board is based around the STM32F103ZET6 which has a lot more pins than mine, and therefore don't  need the addres/data multiplexing. 

The problem is that mine does not have enough pins for the adress bus, only eight. 

So the question really is: How do I connect an external SRAM to the STM32F103VC, which does not have enough pins for the entire SRAM adress bus, using FSMC?
