EXTERNAL MEMORY control via SPI using STM32F410CBT3

I want to control EXTERNAL MEMORY through SPI using STM32F410CBT3 MCU in the system currently under development. It takes up a lot of space because you have to save the audio file.

​How to use EXTERNAL MEMORY using SPI

Please reply. Thank you.

Well, you're going to have to decide on a memory device and model, and then program the SPI bus to match the data sheet of the device.

There are quite a lot of SPI/QSPI NOR Flash memories you could use. Quite a lot of choices in the 16MB (128Mbit) and 32MB (256Mbit)

On the F410 they aren't going to map into the processors address space, so you'd need to read blocks of data into RAM to pass on to other devices/peripherals.

There are also QSPI NAND Flash devices, 128MB (1Gbit), and perhaps MicroSD cards in the 1-bit SPI mode, but not going to be particularly fast.
