DS2401P+*

The DS2401P+* from Analog Devices is an enhanced silicon serial number designed for electronic registration and identification. It features a unique, factory-lasered 64-bit registration number, comprising an 8-bit family code, a 48-bit serial number, and an 8-bit CRC. This device operates within an extended voltage range of 2.8V to 6.0V and communicates via the 1-Wire protocol, requiring only a single data pin.

Designed for reliability, the DS2401P+* has an industrial temperature range of -40°C to +85°C. It is supplied in a compact TSOC-6 surface-mount package and is delivered on a reel for automated assembly processes. Its low-cost nature and minimal interface requirements make it suitable for applications such as PCB identification, network node ID, and equipment registration.

This component offers a unique identity that can be determined with a simple microcontroller interface. It draws power directly from the data line, eliminating the need for a separate power supply and reducing standby power requirements to zero. Multiple DS2401 devices can coexist on a common 1-Wire net, managed by a built-in multidrop controller.
