I am proving MC52259EVB board.
Can anyone soy me what is the maximum size of PEN-USB that I can use.
I want to save a lot of registers for months. I read that chis uC only can use 1 or 2 Mbytes of external memomry. I am thinking to use a USB to store this information.
I need to know what is the maximum size.
thanks.
Solved! Go to Solution.
I'm not sure what kind of limitation you think there is.
1 or 2 Mbytes might refer to the number of address lines of the mini-flexbus interface. It has nothing to do with USB.
2 Gbytes might refer to some kind of limitation of the FAT filesystem. Again, it's not about USB itself. You can choose any filesystem, or work with none at all. That's a design choice, it's yours to make.
There is no fundamental limitation of the maximum size of a USB flash drive. It should be possible to use all of it.
I read,that anyone use up to 2Gb.
Is it correct?

Ok, thank you.
I will use USB to storage datas.
Very thanks.
