1-Wire® products provide combinations of memory, mixed signal, and secure authentication functions with complete operation from a single contact serial interface. With both power and communication delivered over the serial protocol, 1-Wire devices are unmatched in their ability to provide key functions to applications where microcontroller I/O resources are constrained, or system interconnect must be minimized.

Common product features include:

  • Single Contact for Operation and Power Delivery
  • Unique & Unalterable 64bit Serial Number in Each Device
  • Multidrop Capable: Supports Multiple Devices on Single Line
  • Exceptional ESD Performance
