Please let me know the procedure for below
I am new for this design. I would like to know how to interface 4 SRAMs of 32 K bytes to 8051 microcotroller and I am developing code in C language in C51 Keil compiler.
Cy62256-SRAM 11.0592MHZ crystal
What beginner's 8051 project requires 128K RAM?!
Instead, perhaps you should begin with the basics - and just interface one of those RAM chips?
When you've mastered that, try two RAM chips - which will fill the standard 8051's 64K XDATA address space.
Only then should you consider moving on to extending the XDATA space beyond 64K.
In fact, these days, you should be seriously asking yourself whether it's worth the effort of trying to extend the 8051 beyond its limits at all! If you know you will need more memory than an 8051 can support, why even start with an 8051?!
