i have micro controller Motorola MC68331CFC16 on double face board and i want to read the program on the micro controller.
need your help.

When you simply want to copy the thing instead of reverse engineering it it gets much easier than that.P.S. rule of reverse engineering: by the time you've reversed someone elses' work/IP, you've built it yourself at least 2-3 times (unless you just don't know how).
Some firms in China does it much much cheaper than that.Depending on the amount of time and money you have to expend you have some chances to defeat the built in security. They involve dissolving the package with toxic chemicals, using an optical microscope, and microprobing the actual chip. Only a well funded company or government could afford this level of effort.

A starting budget for the effort might run say half a million USD. You got that kind of scratch?
really , I need to copy the application from microcoller in the PCB to another Microcontroller in another PCB board.When you simply want to copy the thing instead of reverse engineering it it gets much easier than that.
Thankfully all programmable chip manufacturers have ways of locking the contents, and unless the manufacturer of the thing you want to copy is stupid enough to leave the protection open you stand no chance.
There may be other ways of getting the code, but it sill is cheaper and faster to write it again than to try to hack the thing. I mean you could theoretically decap the IC and find where the fuse is and somehow change it, but that is a whole lot harder than rewriting the code from scratch. Or you could spend years with differential power analysis and get some portions of the code out.

I gave him the link to some relevant research. I doubt the OP has either the motivation or the resources to execute that plan. In which case I agrre with the out of luck opinion.Do you really thing anyone here is going to help you violate copy protection laws????
