Hi,everyone. Now I want to migrate T89C51RD2 to AT89C51ED2. When I download the same and simple codes to them, and the general 8051-keil's compiler enviroment is included. (and get verified value rightly,so maybe the code has been downloaded to them correctly.) When I put them to my hardware board, the T89C51RD2 can run correctly in it,but AT89C51ED2 can not. Do you know the likely reason? Give me some advice,thanks.
Contact your local Atmel FAE and read the data sheet carfully. There are several differences between the two devices. Bradford
