  15. Dallas - Maxim Integrated - DS2417 - IC, timer. 1-Wire Time chip with Interrupt. SMD.

    Dallas - Maxim Integrated - DS2417 IC, Timer.

    The DS2417 1-Wire Time Chip with Interrupt offers a simple solution for storing and retrieving vital time information with minimal hardware. The DS2417 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 DS2417 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.

    1-Wire Time Chip with Interrupt.

    Package: 6 Pin TSOC SMD.
