Please teach me about FSMC in STM32 MCU.

When the CPU communicates with external MRAM, can FSMC be used?

Interface Type:Parallel

Data Bus Width:16 bit

You need to provide at least which signals are available on that MRAM: data/address/control and the power supply of that MRAM.

Otherwise, you need to check the datasheet of the STM32: the FSMC signals vs what is available on MRAM signals + the power supply.

Check also the application note AN4761 "Using STM32L476/486 FSMC peripheral to drive external memories"

Hope that helps.

Hello @Junki and welcome to the community,

You need to provide the MRAM part number and also the STM32 part number.

The STM32 is the STM32L4 series.
I can't provide the MRAM part number. How can I tell if FSMC can be used?
