sx chip id number

I am somewhat of a novice when it comes to SX chip programming. I have read somewhere that these chips have a manufacturers ID serial number number embedded. If so, how can it be accessed? I would like to use the number as part of security between the program and the device that I am building.
Thank you in advanced for any replies.

    In BASIS Stamp Tokenizer part BASIC Stamp Programming Protocol Parallax describes the ID used in different flavor of BS.
    This ID is send to the editor during initial load of the program but is not made visible in editor itself.

    Is that what you are looking for?

    Look at the SX datasheet. For the SX48, there's a mention of this on page 17. Essentially there's a fixed device ID byte that tells the programming hardware / software which kind of SX is present. There's also a 16 byte area for a user assigned ID that's programmed into the chip essentially as part of the user's program. There's no manufacturer's ID serial number.

    If it is a different number for each chip ,that may be what am after.

    The device ID is fixed. There's one value for all SX48s and another value for all SX20s, etc. The user assigned ID is anything you put there. You can put a different number there for each chip that you program if that's what you want. Nothing gets done automatically and it's not something that the manufacturer does for you.
