DS1644P-120

The DS1644P-120 is an IC (integrated circuit) component that is commonly used in electronic devices for timekeeping and data storage applications. It is a non-volatile memory with a real-time clock functionality. Here is an overview of the key features of the DS1644P-120: 1. Non-volatile RAM: The DS1644P-120 integrates non-volatile static RAM (NVSRAM) technology, which ensures that the stored data is retained even when the power supply is disconnected. This feature is particularly useful for applications where critical data needs to be preserved during power cycles. 2. Real-time clock: The IC component incorporates a real-time clock (RTC) that provides accurate timekeeping and date functionality. It includes features like a programmable 24-hour clock with alarm support, leap year compensation, and automatic power-fail switchover. 3. Battery backup: The DS1644P-120 has an onboard lithium coin-cell battery that serves as a backup power source, ensuring continuous operation even in the absence of the main power supply. This battery backup feature keeps the RTC running and maintains the integrity of the stored data. 4. Industry-standard interface: The IC component follows a standard serial interface protocol, making it compatible with a wide range of microcontrollers and other devices. It supports both SPI (Serial Peripheral Interface) and microwire interface standards for easy integration into various electronic systems
