We already have a product which uses an STM32F427ZIT: For our latest development we are in need of an external RAM. It would be great to control an SDRAM that hosts 128Mbit of memory (Organization

2M word x 16 Bit x 4 Bank

). However we started to configure that 427 in STM32CUBEMX and it looks like it supports SDRAM. When I compile a test project in �Vision 5 and check the Debugger I only see FSMC in the peripheral view.

I searched a bit and only found examples using the STM32F429ZIT with external SDRAM (like the evaluation board). I was confused by this and checked the datasheet and there was no straight word on SDRAM support.

Different sources say that you need a 429/439 for SDRAM. I contacted my FAE but unfortunately he did not reply yet.

What is the common word on this issue? Will my 427 support SDRAM?

    Do You know other test of RAM?

    I use LFSR's to do saturation and retention tests.
