Code Protection

[thetrueman]

Hi All,

I programmed a 12C508a chip and wrote code in configuration to protect the code. I programmed it with EPIC Programmer Ver2.44 and also set the code protection to all in options menu.

The chip is programmed but not protected. When I Read data in EPIC Programmer, it reads the chip and by menu View code it show the contents of the program in Hex format.

Why it does not protect the chip? Any help in the problem???

Are you sure you didn't set them to ALL OFF?

Hi,

Yes while programming at the top of code I confing Code Protect ON and while downloading to chip, in the EPIC programmer software options menu I set Code protection to ALL.

I just read this chip with ALL-100 Universal Programmer and it reads the chip 12C508A. So how to protect the code to be invisible to others???

Some programmers have a setting to read the config in the hex file or not... maybe your programmer is using default settings.

Hi, Thetrueman

1) could you show us your config settings ( from the program AND read from the chip ).

2) now ... keep cool, but the C series chips are really easy to " crack" ...
