 		 #125057 - it's too late
Responding to: ???'s previous message
Hello everybody, really Appreciate all your responses.
Since I don’t have a parallel programmer, nor do I want to make one, I was considering of migrating to P89C51RD2BN or 89C51RD2HBP.
My PCB is already fabricated and I can configure P2.7, P2.6 and ALE to High and PSEN to Low.
Is there any other controller (44 pin PLCC) that can fit in? I am still to decide on Reset IC, I have little space on PCB just enough for 5x2 Burk-stick.
Regards
Vignesh
