 		 #49764 - Replace AT89C52 using AT89C52?
Responding to: ???'s previous message
Hi ,
I used AT89c52 in a PCB and it works well, but When I use AT89s52 to replace AT89c52, It sometimes runs away when it be powered on and powered off. I have checked about WDT, RST pin, DPTR1 that are not available in AT89C52. But I can not find errors. This problem is still boring me! Have you any advices? Please help me ! Thanks!
