For some chips it's quite easy, such as atmel's at89c51 series.

Actually the containt programmed into a microcontroller isn't the same as the containt in the hex file. The **broken link removed**will translate hex into binary before writing into the MCU
If the microcontroller is locked, it's a bit difficult to get the code. For some chips it's quite easy, such as atmel's at89c51 series. For some chips such as microchip's PIC or STC 8051 it's almost impossible to get the code.

so you are saying atmel's technology is cheap (locking) you can break it easily wow

Hi,
I've read in some places, including avrfreaks, that some of the older chips by Atmel, classic AVRs (not sure about 8051 series) had a security bug. If there was power interruption while reading/programming the device, sometimes the lock was opened. This has been fixed in the MEGA and TINY AVRs. I don't know if this applies to the 8051 series of controllers.
Hope this helps.
Tahmid.
I personally dislike this thread and wanted to delete it. I cant support to steal someone's work.
I would ask Mr. Gulson to lock /delete this thread.
