digital serial number IC

I noticed that Dallas semi has some "1 wire" temperature sensor ICs
(DS1825) that come with a unique 64 bit serial number on each device.

I have an application where that serial number would be useful but I
don't need temperature sensor part.

Are there other manufactures that sell a ROM or similar with a unique
serial number onboard? does't have to be 64 bits

thanks.

Are you sure they just don't have a serial number IC or maybe a MAC

address 1 wire IC?

Seems like such a useful feature that more companies would be doing it.

My question should have been "are there any other manufacturers making this
type of part?"

Yes, but they're probably more expensive than the temperature sensors
Dallas sells serial number chips.

I know Texas Instrument also sells the electronic serial number ICs.
It was used in a number of early Apple laptop battery packs and it had
2 pins but looked like a plain vanilla TO-92 transistor. 1 pin for
ground, and 1 for data.

Except that most products have other ways of including a serial number - eeprom, embedded in program
memory etc. so the cost of a seperate chip will often not be justified.

Xilinx has added it to their Spartan 3A series so if you happen to have
an FPGA (which I do in the design that needs it) you get it for free.
