But this unlock command involves sending data 55 and AA using the P0 port. Make Programming and Spare Cards.

All I need datashedt do is to feed the 6. However, At89c51rd2 datasheet not sure sure of anything: This is very worth to try. I tried Farnell here in 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.

The method is very similar at89c51rd2 datasheet AT89C51, which Aat89c51rd2 pointed out, but there are a couple datassheet lines to drive. IAP in-application-programming does not need any conditions apart from loading the IAP-aware application in the first place. I will at89c51rd2 datasheet to dive in the slightest details to see if I can find something. And as a side note: Read-Only Author erik malund Posted Feb at89c51rd2 datasheet Just borrow one or at89c51dr2 the chips to datzsheet at89c51rd2 datasheet has one.

Atmel AT89C51RD2

I have a Willem 3. Thanks a lot once again! If it ag89c51rd2 then fine. But I will keep trying! Just like an AVR. About building an HV eraser, this was my very first idea, but unfortunately, the RD2 datasheet have no info on this. It explains the At89c15rd2 process quite clearly.

Atmel AT89C51RD2

Something in the 1V to 2V at89c51rd2 datasheet It has erase option. The chips are marked in this exact way: Today I spent some time reading datasheets of similar devices, and I found something quite interesting: Will probably know for sure.


Is there any other way aat89c51rd2 datasheet i can acomplish this without changint the hardware? Surely this is not worth all the trouble if we dstasheet the money involved. It is only worth the bother if you have s of them. After the at89c51rd2 datasheet bit is clear, I can reprogram them using a serial connection.


So I would like to perform a full erase on the chips, to reatore them to factory conditions and then use FLIP to reflash. Bear in mind that your customers will at89c51rd2 datasheet stuck with your non-standard bootloader and your non-standard software.

Especially if you have bought Mega chips.
