FAT complexity on Cortex

Hi
I'm deciding which Cortex microcontroller should I use in my project. I will use SD card and FAT filesystem. Is FAT filesystem to complex for Cortex M0 or can M0 perform search, read and writing to files on SD card? What are your experiences on this matter?
Thanks
Dejan

  • Cortex-Mx doesn't really matter here - almost any processor is capable to handle a FAT file system.

    What matters is how much code space you can afford for your file system implementation. And how much RAM you can afford for buffering data (which affects how much work it is to locate the directory entry of a specific file, or how much work to scan the FAT for next file sector or for next free sector).
