The DCMI controller in STM32H7 is faster than F4 and F7. It supports a pixel clock up to 80Mhz. However, is the FMC controller fast enough to acquire such fast data? Let's say, one has an image sensor that generates 10-bits or 12-bits data with 74.25Mhz. Then can she/he use a PSRAM or a SDRAM with STM32H7 to write the image data at a speed of 16-bits x 74.25Mhz ? This question is not about the memory capacity, so please assume that only one image needs to be captured.

You want to be using 32-bit wide memories

With double-buffering, could a PSRAM be also a solution?

Does it improve the bandwidth of the memory interface?
