Hi,
I'm able to burn one micrcontroller P89v51rd2 with my kit...
but when i've changed alone the micrcontroller with the same name i.e p89v51rd2, it is showing not able to connect. it is connecting and burning with that particular micrcontroller.
i'm not able to understand.
Any help..

I've tried other IC P89V52rd2fn . they all r not working..
what should I do now?
how to install bootloader for this particular IC?
is there any difference in hardware connection for burning this IC.? If so, what is the circuit for burning?
