#139673 - It has a standard 8051 external memory interface.. Responding to: ???'s previous message |
...and that interface has a 16-bit address bus - so you can directly address 64K of code space, and also 64K of XDATA space.
If you want to access 128K of CODE space, you will need some sort of Banking (paging) scheme... |
