I am working on 8051. I want access 512k of sram as (external memory).but 8051 has only 16 adddress lines. then how can i access that? Please suggest me .. regards ramesh.
If u can use the paging technique,like u configure some 8 port I/O's as page select signals and then take each page to be 64Kbytes, u can access the 512Kbytes using the 8051. Regards, Rajesh
