[QUOTE="andrew_e30, post: 190461, member: 1161"] hi genius328i, generally the EPROM will be read-protected, for IP purposes. i'm sure you have heard of this before. if you attempt to read or even access the memory, it'll self-erase. i'm not sure about this EPROM from TI if they have that feature, but i know MCP has it. i downloaded a similar EPROM from Atmel and it seems that this EPROM is OTP. what i would suggest is to pump in the address and read from the IOs rather than to extract the HEX file. my 2 cents.....
