Applies to: C251 C Compiler

Answer

QUESTION

Will my 8051 code work with the 251?

ANSWER

Yes. You can literally take an 8051 program in EPROM and run it with the 251. The 8xC251SB is a drop-in replacement for the Intel 80C51Fx series of parts. To run your existing 8051 code with the 251, you must program the configuration bytes of the 251 to enable binary mode compatibility.
