STM32x MDMA maximum Clock speed

I have developed dozens of products using the STM32 Family, but can not find an easy solution for my latest requirement...

 

I need to collect fast A to D samples (from an external 8 bit A to D)... every 20ns.

 

Is it possible to use an 8 Bit parallel port and save 256 bytes into main memory using MDMA clocked using an external 50MHz source?

 

Thanks

Rick
