1-Wire Battery ID and Authentication

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 input/output resources are constrained, or system interconnect must be minimized. Common product features include single contact for operation and power delivery, unique and unalterable 64-bit serial number in each device, and exceptional ESD performance.
