how to use the 16MB SDRAM on keil MCB 1800?

Shreyas007

I wanted to use the 16MB SDRAM on the keil mcb 1800 board.

I didn´t find any examples on how to do it?

Do I have to make any physical connections to use it? 

It would be great if someone can provide the steps for it.

Thanks

    Perhaps NXP has resources, examples or forum you can use? Good technical support from competent engineers tends to be expensive.

    The particular memories tend to be board specific, so the MCU needs to be configured with all the details before it can utilize them.

    You really need to understand this stuff for yourself. It is going to be a function of enabling clocks, enabling pins, setting up the external memory controller for the geometry of device the board has, and configuring the memory chip itself. Most embedded engineers would be expected to perform these tasks, or engage a contractor to provide working code. I don't have code I can furnish you with, you'll have to seek out examples with Google, or on GitHub, etc.

    There should be schematics for the Keil MCB1800 board

    and there are no doubt technical manuals for the NXP MCU to provide additional context.
