Maxim Integrated DS1216D SmartWatch RAM
The DS1216D SmartWatch RAM from Maxim Integrated is a state-of-the-art memory module that offers a unique blend of volatile and non-volatile storage capabilities. This innovative product is designed to retain data without an external battery when the host system is powered off, thanks to its built-in watch function and lithium energy cell.
The DS1216D seamlessly integrates with standard x 16 static RAMs, converting them into non-volatile memory with the added benefit of a real-time clock (RTC). This integration is made possible by the SmartWatch's transparent operation, which does not require changes to the existing RAM interface, ensuring ease of use and compatibility with existing systems.
The device features a full-function, real-time clock that includes a day of the week, date, month, year, leap year, hours, minutes, and seconds. The clock is accurate to ±1 minute per month at 25°C, making it a reliable timekeeping solution for a wide range of applications. The DS1216D also boasts an automatic leap year compensation valid up to 2100, further enhancing its precision and longevity.
With a wide voltage range of 2.0V to 5.5V and a temperature range of -40°C to +85°C, the DS1216D is designed to perform reliably in diverse environmental conditions. Its energy-saving design allows for a battery life of over 10 years, ensuring long-term data retention and clock functionality.
The DS1216D SmartWatch RAM is an ideal solution for applications that require both volatile and non-volatile memory storage without the need for an external battery. Its applications include utility meters, security systems, data loggers, and other systems where data integrity and accurate timekeeping are crucial.
Overall, the Maxim Integrated DS1216D SmartWatch RAM is a compact, efficient, and highly reliable memory component that offers designers the convenience of easy integration with existing systems while providing the dual benefits of non-volatile storage and real-time clock capabilities.
