Guys,
I'm just wondering, Is it possible to use my old DDR SDRAM PC133 module from my old PC for FSMC on STM32F103VCT6, I can see one chip for 8Mbytes, not bad for my experiment and it's cheap... The type is GM72V66841ET75.....Any ideas ? thanks #circular-conversation- Mark as New

It's not DDR, and it's not going to work on STM32F1/F2 parts. It might be usable with the F429/F439 parts.

Look at the STM3210E-EVAL, and add more high-order address bits.

what's the different between 512 x 16 and 1024 x 8, does it matter or the different is per word only ? can I use STM32 with x8 ?
The 16-bit wide ones would give you better bandwidth, I suggested a schematic based on the part you specified, for the 8-bit you'll have to source your own. I believe it should support 8-bit parts, review the documentation.Up vote any posts that you find helpful, it shows what's working..

NO, Please refer to original response. The F1 parts DO NOT SUPPORT SDRAM/DDR2/DDR3Up vote any posts that you find helpful, it shows what's working..

x 4 pieces, am I right ? thanks I don't know, what are the requirements? Would it be more practical to use an STM32F429I-DISCO with 8MB of SDRAM already present, and a screen? Do you have any experience with ucLinux? If you need support you'd be better picking a device/board that people are currently doing development work on, the F1 series is rather slow and dated in 2014. Check what emCraft.com are supporting.Up vote any posts that you find helpful, it shows what's working..
