Help with selection of external memory.

I am using DCMI peripheral to drive camera modules. At this point, I am able to obtain images with 320x240, 16 bits/pixel. I am working with a display connected via FSMC to the MCU and the display already provides enough memory space. But now I want to increase the image resolution to 1600x1200, 16 bits/pixel. For that, I think I'll need about 4 MiB available. Could anyone give me suggestions of memory module [type (SRAM, DRAM), brand, etc) that I could use?

Before deciding on this detail, think first about the possible consequences of increasing the resolution - thus required processing and shear data movement requirements - 25-fold.

You may perhaps want to do more substantial architectural changes and move to more powerful platforms.

I am currently using an STM32F407VG. Isn't it enough to handle it?

That's yours to decide.

As

meant: 1600*1200 / 320*240 =

I hope you realized the implications.
