Re: 8051 64K external SRAM possible?
Of course it is possible. P0 and P2 give 16 address lines. You are
adding XDATA which is 64K external data. This is a seperate space to
the iData and Data. (though confusingly some 51]s have "internal xdata"
that is an additional space.)
There is a description of this in thje C51 Primer at
