Hi!

I hve been using Philips micrcontroller P89C51RD2HBP for a few months.

Now i hve bought new set of RD2 chips but the extension is P89C51RD2BN(pls note the older chips comes with HBP now it is BN).

Evnthgh i could program the new chip (i.e Erase it and load the program thrgh WINISP)i am not getting the intended output.

I am sure there is no mistake in the program bcos the program works well in the same board with the older chips(HBP).

Can any one help me?

Thank u
