Hello,
I am working on a early stage prototype layout for an LPC2468 based
system and am looking for NAND flash to use on my system.
I've been looking through Mouse/Digi-Key/Avnet and am not able to find
any large NAND flash modules (looking for 128MB or 256MB modules).
Where might I be able to find a distributor for perferably Samsung
memory modules that would sell in low quantities?
If not samsung, any of the others, Intel, ST, etc is fine if I could
find a distributor.
Mouser used to have a bunch of ST memory but they claim that ST is
discountinuing their line of memory chips.
NAND Flash memory suppliers?

Just out of curiosity, do you have a NAND software driver as the
LPC2468 does not support NAND Flash!?
Such a driver is far from trivial.

A "driver" (low level access including ECC but without handling bad
blocks and file level routines) for 512 byte sectored NAND flash can
be found on NXP's website.

Thank you for pointing out that distributor. I will be checking out
their line up.
Also It is my understanding that a most of the demo boards for the
LPC23xx and LPC24xx are all shipping with NAND flash. Perhaps I have a
misunderstanding about the memory options?
If not NAND then what would the correct option be?

I don't know about 'most' but e.g. the Embedded Artists LPC2468 and
LPC2478 OEM boards ARE equipped with 128MB of NAND Flash (as well as
4 MB NOR FLASH):

Right, I have looked at schematics for 3 additional LPC2468 designs
that utilize NAND for their bulk flash.
I am currently working with an IAR KickStart 2468 board that looks
like its using a samsung NAND flash chip. I'm just starting to
transition over from a 2368 so I have not yet gotten around to doing
anything with the external memory.
Why would the interface be any different as long as its flash memory?
I thought that the PrimeCell controller on the ARM would interface as
long as it utilized the same/standard interface.
