Hello Harshad,

"Have you tried 89V51 any time?."

No,I recently bought 10 pieces to test it out, the first one conked out, so I continued with the 89C669 which I am working with.

I have tested out IAP with 89C51RD2BN and the 89C669FA, and it works.

I think prices of 89V51RD2 could go down in the near future.

Regards,
John.
