how does fmc work does it use spi?

FMC is a peripheral to connect parallel memories.

So no, no SPI (which is a serial protocol).

Hello,

FMC as Flexible Memory Controller and it manages parallel signals. It's used to connect external parallel devices like memories, LCDs etc. The interface has three types of signals: Data, Address and Control.

The following is an example of a connection of an SRAM and a NOR flash to STM32L476 device (STM32L476G-EVAL board).

So no relation with other protocols or comm interfaces such as SPI or UART ..
