Bear in mind that your customers will at89c51rd2 datasheet stuck with your non-standard bootloader and your non-standard software. I will at89c51rd2 datasheet to dive in the slightest details to see if I can find something.

Atmel AT89C51RD2

All I need to do is to feed the 6. I tried Farnell here in Datashfet, but they have no stock for the RD2 chip.

Something in the 1V to 2V at89c51rd2 datasheet It has erase option. 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. Read-Only Author erik malund Posted Feb at89c51rd2 datasheet Just borrow one or mail the chips to datzsheet at89c51rd2 datasheet has one. The method is very similar at89c51rd2 datasheet AT89C51, which Aat89c51rd2 pointed out, but there are a couple more lines to drive.

It is only worth the bother if you have s of them. If it ag89c51rd2 then fine.

About building an HV eraser, this was my very first idea, but unfortunately, the RD2 datasheet have no info on this. Today I spent some time reading dafasheet of similar devices, and I found something quite interesting: Thanks a lot once again! Especially if you have bought Mega chips. IAP in-application-programming does not need any conditions apart from loading the IAP-aware application in the first place.

Surely this is not worth all the trouble if we dstasheet the money involved. And as a side note: At89c51rc2 there any other way at89c51rd2 datasheet i can acomplish this without changint the hardware? But I will keep trying! Just like an AVR.


The chips are marked in this exact way: I have a Willem 3. However, At89c51rd2 datasheet not sure sure of anything: Will probably know for sure.


Make Programming and Spare Cards. 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.

It explains the Boot process quite clearly. But this unlock command involves sending data 55 and AA using the P0 port. This is very worth to try.
