#75167 - RE: NoTouch for Maxim's
Responding to: ???'s previous message
Erik, somewhere you wrote all new chips when powered on for the first time, switch to serial programming mode automatically (no pin magic required) - Do you know how it is achieved? Could it be that they have a notouch style program factory written in their program memory? Maxim serial programming protocol allows dumping the code memory as Intel .hex file. I wonder if such noTouch could be reverse-engineered by dumping the .hex of such memory.

On the other hand, it may be done very differently, how such original factory bootstrap could be overwritten in OTP/EPROM (no EE) chips?

Anyway, it may be interesting to see, will it all be zeros or will there be something in such a "virgin" memory?
