MC9S08GB60 Internal Number

Is there an internal unique number that is recorded in the MC9S08GB60 that I can read using C that would be unique with each CPU?

No,
There is no serial number you can read.
However, some programmer are able to create one when the software is put into Flash in the programming house.
Cheers,

Hello,

P&E have a "Serialize" utility available from their web site. This might do what you you require.

If you have need of a peripheral, see if you can get a unique number from that.

I have a small weather device that I used a DS18S20 temerature sensor part on, and it's 1-wire address is perfect for providing a serial number on the fly for the entire unit. Hey, if you gotta have the part anyway, choose it wisely!

The only caveat is if you change that part... I've had 2 units where I had to change that part. One shorted out and the other was physically broken off the unit. (It sticks out to have the best response time to temperature changes.) I had to make allowances in my tracking software to be able to change that number 'on the fly' for repairs.
