Hi,
I am a working on a project which requires a fairly large buffer (~40MB) to temporarily store the data.
I think the best option would be an SDRAM chip (something like this: https://www.mouser.co.uk/ProductDet...=sGAEpiMZZMti5BT4iPSEnVhJA8KDV46tn3dqXLk4ebc=), however, since it has a lot of pins, I am not sure if Teensy 4.0 can handle it (or me for that matter since I have no experience with this).
Another option I found is flash memory with Quad SPI (something like this: https://www.mouser.co.uk/ProductDet...5HL512TFANHI010?qs=BJlw7L4Cy7%2B6M3sHZp0BRA==). Which seems a bit easier to implement (or at least the single SPI mode is), but I am not sure if it is possible to use Quad SPI on Teensy 4.0?
From the microcontroller datasheet:
So I think both of those would be supported with the i.MX RT1062 I am just not sure if the Teensy 4.0 has all the required pins exposed?
Has anyone here done something like this before and could share some advice/documentation/example code to do it?

From the microcontroller datasheet:
External memory interfaces:
— 8/16-bit SDRAM, up to SDRAM-133/SDRAM-166
— 8/16-bit SLC NAND FLASH, with ECC handled in software
—SD/eMMC
— SPI NOR/NAND FLASH
— Parallel NOR FLASH with XIP support
— Two single/dual channel Quad SPI FLASH with XIP support
