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, lasered ROM 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.  
OVERVIEW  
The DS2415 has two main data components: 1) 64-bit lasered ROM, and 2) real-time clock counter  
(Figure 1). The real-time clock utilizes an on-chip oscillator that is connected to an external 32.768kHz  
crystal. All data is read and written least significant bit first. The real-time clock functions will not be
