DS1644P-120+

The DS1644P-120+ is an integrated circuit (IC) component produced by Maxim Integrated. It is a real-time clock (RTC) module with additional features that make it ideal for various timekeeping applications. Here, we will provide an overview of the DS1644P-120+ and highlight its key features. The DS1644P-120+ is built for accuracy and reliability, offering clock/calendar functions with a timekeeping capability of 100 years. It has a 14-pin DIP (Dual Inline Package) design, making it easy to integrate into existing circuitry or connect to compatible systems. One of the standout features of this IC is its non-volatile RAM (NVRAM). It provides a convenient and power-efficient way to store data, even when the power supply is disconnected. The DS1644P-120+ has a capacity of 256 bytes for storing important information such as system configuration settings, user data, and alarms. To maintain precise timekeeping, the DS1644P-120+ utilizes an integrated crystal oscillator, ensuring accurate timing even in challenging environments. This RTC module supports both 12-hour and 24-hour time formats and includes a leap year compensation feature. The DS1644P-120+ can be easily configured and controlled using a standard I2C (Inter-Integrated Circuit) interface. This simplifies the integration process and allows for communication with a microcontroller or other compatible devices
