In the MCS-51 books explain that memory allocation was 64Kbytes? You need to read it more carefully! The 8051 has several distinct memory address ranges - the two 64K ranges are CODE and XDATA. something like 24C64 or 27C64 chip should enough for program/data memory See above CODE is program memory - 64K; XDATA is a distinct 64K address space. As far as the 8051 is concerned, there is no such thing as "program/data memory". How to upgrate such thing?? is possible for 24C512 or 27512 chip? What do you mean? You might want to try looking-up "Banking"... You should also ask yourself why you want to go beyond the architecture's design limits? Why not just choose a processor that meets your requirements directly? (you may have good reason, in which case you should explain it so that people can give appropriate answers). |
