Hi, 

I am using F405's FSMC to connect to a FPGA, I am planning to configure FSMC in SRAM/PSRAM mode, however, I only want to use 4 address lines, A[3:0], can the rest of address pins to be configured as GPIOs or other muxed funcions?Frank

Yes, I might use higher order addresses, look at NAND devices, they use only a handful of address bits. Your FPGA will still take a 64MB decode space.
