DS1746W-120

The DS1746W-120 is an integrated circuit (IC) component that offers a range of useful features for various applications. It is a static RAM with a built-in Real-Time Clock (RTC) designed by Maxim Integrated. Below is an overview of the key features and functionalities of the DS1746W-120 IC component. 1. Non-Volatile RAM (NVRAM): The DS1746W-120 combines the benefits of both volatile and non-volatile memories. It includes a 32k x 8 SRAM memory which stores data in a non-volatile manner. This means that even in the absence of power, the data stored in the memory remains intact. 2. Real-Time Clock (RTC): The DS1746W-120 incorporates an RTC module, which provides accurate timekeeping capabilities. It includes a dedicated clock/calendar counter and a programmable alarm system. The clock operates in the hours, minutes, and seconds format, while the calendar supports day, date, month, and year information. 3. Integrated Battery Backup: The DS1746W-120 IC features an on-chip lithium energy source that powers the RTC and ensures data retention during power outages or system failures. This eliminates the need for external power backup solutions and simplifies the design. 4. Power Control: The IC component includes power control circuitry, allowing for power switching and power-fail control
