Hello everybody,

What i mean here is, whether, P89V51RD2FA Philips = P89V51RD2FA NXP, include all the features like architecture, function, timer, etc?
Because when I'm using SAME program load into both Philips and NXP, Philips having trouble while NXP no problem.

Thanks for your reply.

Flash Magic will also complain about the device signature not matching.

So, you just ignore the signature right? Ignore shouldn't affect our program right?

Q1: what happen to previous version of bootloader? The NXP Tech support team send me V7. Can you answer this with plain and simple English as i very dump in english? Bootloader won't affect my user program right?

Supplier send me 20pcs of NXP and 30pcs of Philips. Both are same part number P89V51RD2FA. My programmer (BPWin) contain Device P89V51RD2 only without the last 2 alphabet.

Q1: All NXP IC always detect wrong ID as "Chip's ID = 00BF0093 Expected = 00BF0091". What is this about? What happen?

Q2: All Philips IC also same with above and create another problem, the data not match with buffer...

Q3: Is NXP = Philips?

Q4: What is Parallel Programmer? Is BPWin (one of the programmer) consider as Parallel Programmer?

Q5: What is bootloader doing? Is bootloader secured inside the IC? If yes, we can't erased it right? If not, what programmer can do that? Only FlashMagic can do that?

Q6: How to purchase FlashMagic? Can update my bootloader by using 1 DB 9 connector and connect to Vdd, Vss, TxD, RxD and RST? But how? any schematics diagram to show me?

Please help me, thanks.
