Use an external SRAM instead of SDRAM is possible?

[Pbern.11]

Good Morning, i'm implementing a HMI with TouchGFX based on STM32F429V LQFP100 that not support SDRAM on FMC. In your opinion it's possible use an external SRAM instead of a SDRAM like IS42S16400 present on STM32F429I-Disco? I need to use external memory for graphic buffering (display could reach 640x480 pixel 16bpp)

Thanks a lot

AFAIK, SRAM is not supported by the 100-pin package either.
