Will probably know for sure. Thanks a lot once again! The chips are marked in this exact way: This is very worth to try.

Especially if you have bought Mega chips. So I would like to perform a full erase on the chips, to reatore them to factory conditions and then use FLIP to reflash.

It is only worth the bother if you have s of them. It explains the Boot process quite clearly.

Make Programming and Spare Cards. I will at89c51rd2 datasheet to dive in the slightest details to see if I can find something. However, Af89c51rd2 datasheet not sure sure of anything: IAP in-application-programming does not need any conditions apart from loading the IAP-aware application in the first place. About building an HV eraser, this was my very first idea, but unfortunately, the RD2 datasheet have no info on this. Is there any other way at89c51rd2 datasheet i can acomplish this without changint the hardware?

I have a Willem 3.

Surely this is not worth all the trouble if we dstasheet the money involved. And as a side note: Bear in mind that your customers will at89c51rd2 datasheet stuck with your non-standard bootloader and your non-standard software.

Today I spent some time reading datasheets of similar devices, and I found something quite interesting: Something in the 1V to 2V at89c51rd2 datasheet It has erase option. The method is at89v51rd2 similar at89c51rd2 datasheet AT89C51, which Aat89c51rd2 pointed out, but there are a couple more lines to drive. But this unlock command involves sending data 55 and AA using the P0 port. After the at89c51rd2 datasheet bit is clear, I can reprogram them dstasheet a serial connection.

I tried Farnell here in Brazil, but they have no stock for the RD2 chip. Just like an AVR. If it ag89c51rd2 then fine. Read-Only Author erik malund Posted Feb at89c51rd2 datasheet Just borrow one or mail the chips to datzsheet at89c51rd2 datasheet has one.

USING MULTI-FUNCTION PINS ON ATMEL AT89C51RD2

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.

All I need fatasheet do is to feed the 6.

But I will keep trying!
