The DS1742-100 is an integrated circuit (IC) component with a real-time clock (RTC) function. It offers accurate timekeeping capabilities and several key features that make it suitable for various applications.
One of the notable features of the DS1742-100 is its ability to function as a non-volatile memory, allowing data storage even when the power is disconnected. It has 4096 bytes of SRAM, which can be accessed through a simple interface, making it convenient for data logging and other similar tasks.
The DS1742-100 incorporates a precision RTC with a built-in oscillator, ensuring accurate timekeeping. It can track time in hours, minutes, seconds, as well as days, months, and years. The RTC also incorporates an alarm function, making it possible to trigger specific events at programmed times.
To enable efficient data transfer, the DS1742-100 supports both serial and parallel interfaces. The serial interface utilizes an I²C bus, allowing for easy integration with various microcontrollers and other ICs. On the other hand, the parallel interface provides direct access to the SRAM, enabling fast data read and write operations.
Another key feature is the DS1742-100's low power consumption. It has a battery backup input pin that allows it to operate using a separate power source, minimizing power usage when the main power supply is disconnected. This feature is particularly advantageous in applications where power efficiency is crucial
