Hi,
I work on ST10F168 and i use external ram by EBC in 16 bits demux mode.
There are 4 Chip Select available for ram : CS1,CS2,CS3,CS4
and 23 adress bits : A1->A23
So, there are (2^23 * 4) bytes accessible <=> 32Mo
I would to know if i am right and if i can declare an external memory map of 32 Mo !
Thanks for any suggestions !
Regards,
Jim

Hello Jim,
Unfortunatly the ST10 address range is limited to 16Mo (internal Flash included) because we only use 24 bit to create the total absolute address.
Bye
