Description

The DS2415 1-Wire® time chip offers a simple solution for storing and retrieving vital time information with minimal hardware. The DS2415 contains a unique, factory-lasered 64-bit ROM registration number and a real-time clock/calendar implemented as a binary counter. Only one pin is required for communication with the device. Utilizing a backup energy source, the data is nonvolatile and allows for stand-alone operation. The DS2415 features can be used to add functions such as calendar, time and date stamp, and logbook to any type of electronic device or embedded application that uses a microcontroller.
