The L138 device supports up to 512MBbytes of DDR2 memory, however, you need a memory that uses 14 address pins.

Thanks for your reply!

At now, large capacity DDR2-component (>=2Gb) Row-address >= 15-bit(32768) and OMAP-L138 DDR2/mDDR memory controller's DQ width only 16-bit.

I can not find DDR2-component can consist 512MB capacity.

Do you can recommend DDR2-component and part-number?

Thank you!

Unfortunately last time we checked (about a month ago), there wasn't a memory solution available for the L138 that could get you to 512MB at a reasonable cost.
