We are developing a microblaze base system for which we want to use LogiCORE IP AXI External Memory Controller v1.03a to access MAXIM DS1553 NV RAM present on our custom board. NV RAM has WE, CE, OE, ADDR[12:0], DATA[7:0] and INTR pins. However, emc has huge list of EXternal Memory Interface Signal. So, we wanted to know that will it be fine to keep extra ports open which are not required to map MAXIM DS1553 NV RAM? Or we have to make our own memory controller. Also, we wanted to know, if this emc is specific to some evaluation board?

Thanks you for your reply.
May I get some information on my first question “we wanted to know that will it be fine to keep extra ports open which are not required to map MAXIM DS1553 NV RAM?” Like on page 23, for IS61LVPS25636A Async SRAM parts, some of the ports are left unconnected.

I am sorry, I could understand your reply.
Although its seems from the datasheet that it will be fine to keep unsed ports open.
