Is it possible to copy this to any OTP chip? Thing is that I don't want anyone else to copy this SW. BR Mattias

Salam, Correct me if i misunderstood you. You'd like to protect your firmware (read protection). Ok OTP chips are One Time Programmable that mean you program it one time only. But you can read as many as you want. Do you use any MicroController in your design ? Bye

I didn't know OTP's were readable. I thought that was one of the reasons why they were used was. Am I mistaken about this?

Hello, There is also a microcontroller on HW. I also tought that most of OTPs was impossible to read/copy. Does anyone know if there is a replacement chip for the AM28F512 that is harder to copy? otp/prom/else? Troubles? Changes/conversion of code? BR Mattias
