- Tempest1981 2y agoAnyone remember the Dallas Semiconductor DS2400/DS2401 https://www.analog.com/media/en/technical-documentation/data-sheets/DS2401.pdf https://www.analog.com/media/en/technical-documentation/data... 1-Wire, unique 48-bit ID. I don't remember the year it was introduced, or cost.

IIRC, their 1-wire temp sensors also have that (at least they did about 10 years ago when I was messing around with hobbyist electronics): https://www.adafruit.com/product/374 https://www.adafruit.com/product/374
- mmoskal 2y agoRight some of them do. I just recall the cheapest STM32G0s not having them (though they did have OTP so you could burn it yourself).
