external Flash and RAM with LPC2378

Hi!

I have MCB2300 board. Now I would like to do an own board. I need fast storage data, so I chose for external SRAM (I need at last 128kB) with battery. I also need DataFlash.

1.) Have anyone some HW example, how to connect it (which pins are used) or just link?

2.) RTL have support for memory. It is posible to user RTL for external Flash and external SRAM at the same time?

Thans for your help

You should look at the Datasheets for the appropriate parts.

Also look for Application Notes, design guidelines, etc on the appropriate Manufacturers' websites

I read datasheed and RTL documentation and if I understand correcty, RTL support just 2x64kB, because lpc2378 have just 16 pins for addressing and one two pins for select activ memory. This could be enougth for SRAM.

So If I want to bigger flash, I have to write my own driver function, or is some other solution?
