The DS1243Y-120+ is an IC component that offers non-volatile timekeeping functionality. It is a part of the DS1243 series produced by Maxim Integrated. This IC component is widely used in various applications, including data loggers, automotive systems, industrial control systems, and portable devices.
Key Features:
1. Non-volatile SRAM: The DS1243Y-120+ provides 8kb of non-volatile static random-access memory (SRAM). It retains the stored data even when the power is turned off, ensuring data integrity during power failures or system shutdowns.
2. Integrated Real-Time Clock (RTC): This IC component incorporates a real-time clock that provides timekeeping functionality. It accurately keeps track of time, including hours, minutes, and seconds, based on a 32kHz crystal oscillator.
3. Battery Backup: The DS1243Y-120+ includes an onboard lithium energy source that powers the IC during power loss situations. The battery backup ensures that the SRAM data and timekeeping information remain intact for an extended period.
4. VERSACELL Battery Connection: It offers a VERSACELL battery interface, enabling easy connection to an external battery. This feature simplifies the replacement or maintenance of battery backup.
5. Integrated Control and Status Registers: The DS1243Y-120+ comes with control and status registers that allow users to configure various parameters, such as time format, alarm settings, and battery monitoring
