    Fast Parallel Port (32bite wide) to interface external IC using STM32F7 or H7

      Hi,

      How fast it is possible to drive external IC using Paraller Port (32bit wide, mixed PINs from various port) via DMA or other technics. I have connected also exteral SDRAM to MCU.

       

      It is possible to achive about 40 - 50 MHz update freq ot entire port ?

       

      Thank you in advance for all sugesstions.
