Thanks Runzhong for the suggestions.
We need 16bit wide SRAM interface so NAND flash port doesn't suit us.
We plan to build SRAM on top of GPIO system.
The interface is going to be used sporadically for a fraction of second,
so I guess we will be able to take the CPU fully (no DMA) while it is

It depends on your needs. If simply want to expand some DI/DO, ADC/DAC
or some other peripheral, USB maybe a good, cheap and expandible
option. I don't see too much needs in SRAM interface. If you
desperately need a parellel interface, you can use nand flash
controller with a small CPLD.
Hi All,
I am wondering if Allwinner A10/A13/A20 SoC can support external asynchronous
memory. (8/16 bit Data bus, Address bus, \RD, \WR, \CS)
I don't see information about this in the A20 datasheet.
Is there some software component in sunxi Linux about this?
Pointers are very welcome.
Thanks
