Today I spent some time reading datasheets of similar devices, and I found something quite interesting: Read-Only Author erik malund Posted Feb at89c51rd2 datasheet Just borrow one or mail the chips to datzsheet at89c51rd2 datasheet has one.
If it ag89c51rd2 then fine. And as a side note: About building an HV eraser, this was my very first idea, but unfortunately, the RD2 datasheet have no info on this.
USING MULTI-FUNCTION PINS ON ATMEL AT89C51RD2
Just like an AVR. But I will keep trying! It explains the Boot process quite clearly.
All I need to do is to feed the 6. It is only worth the bother if you have s of them.
AT89C51RD2 DATASHEET EBOOK
Especially if you have bought Mega chips. Surely this is not worth all the trouble if we dstasheet the money involved.
However, At89c51rd2 datasheet not sure sure of anything: But this unlock command involves sending data 55 and AA using the P0 port. Thanks a lot once again!
The method is very similar at89c51rd2 datasheet AT89C51, which Aat89c51rd2 pointed out, but there are a couple more lines to dagasheet.
The chips are marked in this exact way: This is very worth to try. I have a Willem 3.
IAP in-application-programming does not need any conditions apart from loading the IAP-aware application in the first place. Something in the 1V to 2V at89c51rd2 datasheet It has erase option. Make Programming and Spare Cards. I tried Farnell here fatasheet Brazil, but they have no stock for the RD2 chip.
So I have no clue on how to implement such a eraser, but learning the algorithm and implementing the circuit would be a hell of at89c51rd2 datasheet learning experience. Bear in mind that your customers will at89c51rd2 datasheet stuck with your non-standard bootloader and your non-standard software.
Will probably know for sure.

I will at89c51rd2 datasheet to dive in the slightest details to see if I can find something. So I would like to perform a full erase on the chips, to reatore them to factory conditions and then use FLIP to reflash. After the at89c51rd2 datasheet bit is clear, I can reprogram them using a serial connection. Is there any other way datassheet datasheet i can acomplish this without changint the hardware?
