PoP and MCE memories for Sitara AM3517
I'm very new with TI Processors and I'm trying to develop a custom board based on AM3517. Looking for memory modules I've found MS29C2G24MAKLA1-XX from Micron witch is a PoP device containing such NAND Flash and LPDDR memories.
My cuestion is that I've read on the memory vendor selection guide that Sitara AM35x does not support PoP memory devices, only discrete memory and I'd like to confirm if I can't use this Micron Module (I've read on Micron's website that these devices are Sitara and Omap compatibles).
Also I'd like to know any guide explaining the different kinds of RAM memory technologies. I've been looking for differences between DDR2 SDRAM and LPDDR memory for better choice (I'm very new in embedded ARM desing and these will be my first design) and I didn't found any good explanation.
Thanks for all.
Regarding the differences between various memory technologies, some simple Google searches should get you the information you need.
I can confirm that the AM3517 (and AM3505) does not support PoP memory technology. The AM3517 does support DDR2 through its DDR memory controller, but the memory must be instantiated on the PCB instead of placed on top of the processor as in PoP memory configurations. The AM3517 (and AM3505) does not have pads on the top of the package to accept a PoP memory device.
Ok, thanks for your reply. I suppouse I can mount a the memories PoP package directly into the PCB. It isn't true?
You would need to get this information from the memory vendor. I don't have specific experience with this method and would suspect this is not a viable option.
