Codes are the same .. the main difference is that you can program the "S" verison through ISP (in application) or using very simple programmers, while the "C" version still needs "full" parallel programmer ..

difference between 89s51 and 89c51

my few pieces of "S" version sometimes forget the flashed program. I stopped use it, but I cannot say that is general problem or only my few pieces. Atmel technicians did not help me.

89s51 has more new feature than 89c51
such as
- ISP programming ( In system programming)
- Watch dog timer
therefore , its price is cheaper than 89c51
