DS1644-120

The DS1644-120 is an integrated circuit (IC) component designed by Maxim Integrated, widely used in electronic devices for real-time clock (RTC) and non-volatile memory applications. This versatile IC offers several key features that make it a popular choice in diverse applications. One notable feature of the DS1644-120 is its reliable, built-in RTC functionality. With an accuracy of ±3 minutes per month, this component ensures precise timekeeping, making it suitable for applications requiring accurate time calculations or scheduling. It supports both 12-hour and 24-hour time formats, simplifying integration into various systems. Additionally, the DS1644-120 boasts non-volatile memory capabilities. It provides 256 bytes of electrically erasable programmable read-only memory (EEPROM), which is organized into four pages for data storage. The EEPROM allows for flexible and efficient data storage, retrieval, and updating, making it ideal for applications requiring data logging or configuration settings retention. Another advantageous feature is the DS1644-120's ability to operate over a wide voltage range, typically from 4.5V to 5.5V. This flexibility enables integration into different power supply configurations, contributing to its versatility. Furthermore, the IC includes an auxiliary power input pin that allows the device to run solely on battery power, enhancing reliability by enabling backup power during sudden main power outages. This feature ensures that critical RTC functions remain operational and minimizes data loss
