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
Q: Is it a school job?
A: no no
So what, exactly, is the objective of this exercise?
With 32-bit processors almost for free, I would not spend any time on building banked memory solutions for a new product.
The situation would be completely different if you already had invested a lot in an existing product and need a quick solution to extend it past a hard limit.
Besides the extra chips to decode the memory addresses, the software complexity will also increase.
By the way - why so much RAM? Are you going to run the application from RAM, or do you really have that much dynamic data to keep track of? It is quite common that much of the data are semi-static and can be moved to a large serial flash instead. A data logger that needs more bandwidth can be built with an external address counter, so the application (or external hardware) just writes out data a byte at a time, without thinking about the address. That would allow fast storage of many megabytes of high-speed-captured ADC data for example.
