Hi everyone, this is my first question.
I use STM32F746 and I need to interface SDRAM and this MCU. Micron SDRAM was used at the STM32F7 discovery however, at my stution this is not possible. There is any alternative to this SDRAM
SDRAMs are pretty much standardized so probably any of the will do.
Select a model and come back to talk about it.
External memory interface on the FMC may have different characteristics and price.
For very fast (maximum) operation code - SRAM memory is less than 10ns access over time, for example: IS61WV20488BLL 4 pieces. Expensive - but very quickly.
Option high volume and low cost SDRAM - 3.3V, for example MT48LC32M16A2P-75. This is for the graphics, but slowly.
Option almost free SDRAM 3.3V 128Mb. Memory for screen graphics, the cost is very low, the speed is low. QUADSPI flush memory works a little slower, but it has a low cost and high volume. Bundle of two types of memory gives acceleration and a low cost.
Start by constraining your search space a little. What size of SDRAM do you need? How wide of a data bus are you looking to implement? How fast does it need to be? If the factors stopping you from using the Micron part impact your choices of other parts, expand on that a little. ie price, availability, embargoed?
