Interfacing 8051 with SRAM (AS7C256)

8051 with sram

Hi,
I am trying to interface an 8051 (at89C52) microcontroller with AS7C256 for my project. I am working on sensors, where the sensor data from the microcontroller (at89c52) is to be stored in the Sram. It would be very helpful if someone has a code ( in C) for the interfacing....Thank you.

If you use the Keil compiler (2k byte version free) to map variables to XRAM (external RAM)

Hi,
Do you have any sample code, so that i can try to understand from there. i am new to microcontrollers.Thank you.

Please understand this is not a software issue ..

Connecting an external RAM(SRAM) to 8051 is purely hardware issue ..

8051 addresses internal or external RAM locations using pointers (R0, R1 or DPTR; see:
)

.. and there are NO SPECIAL SOFTWARE routines (C or assembly) to do so ..
