Hi,

I am writing an embedded application where I need to use a NAND file system. The system resources are limited (I‘m using a microcontroller from the STM32F205 family, 256kB Flash, 128kB RAM).

I plan to use the HY27UF081G2A NAND memory (128MB, 2kB page size, 128kB erase block). I would like to keep the RAM footprint as small as possible (50kB RAM at most; including the NAND driver, buffers etc.). Do you think I could fit?

Is there a way how to estimate the needed resources for different NANDs? I only found the page http://www.yaffs.net/yaffs-memory-footprint which seems to be outdated and valid for YAFFS1 only.

Thanks,

Marek
