Abstract:Embedding a DS2431 (1-Wire) chip in the near end of a cable allows a system processor to identify a cable
(manufacturing date, revision, configuration, calibration data, etc.) and to authenticate it (to prevent the use of inferior
counterfeits).

This design idea appeared in the August 27, 2009 issue of Electronic Design magazine.

Electrical cables remain of critical importance for interconnecting equipment ( Figure 1). Yet, cloned and knock-off cables are a
