Which parts have FSMC?

We have an application that requires an external memory controller, and I can't see any obvious way to identify all the STM32 parts that contain the FSMC.  It's just not an option on the parametric search.  Anybody know of a document that lists all the parts, or some way that's easier than looking at each subfamily in turn?  Maybe I'm missing something obvious. Thanks.

For the STM32F1 you need High Density variants.

For the STM32F2 you need parts >= 144 pins to escape the signals you need. Some of the 100 pin devices provide some of the signals, you'd need to go through the exercise of seeing if you can get everything you need out of the package, ie FSMC + peripherals.

See Table 2, work through Table 6

Also STM32F4 family has the FSMC.

For IOs selection (& eventually MCU), you can try

MicroXplorer

. I heard that it is a good tool.
