The DS1244Y-150 is a highly integrated, full-featured memory and real-time clock (RTC) module from Maxim Integrated. This product is designed to provide a reliable and durable nonvolatile memory solution with an embedded timekeeping function. It is particularly suitable for applications that require data and time to be maintained even in the absence of power.

Key Features

• Memory Capacity: The DS1244Y-150 offers a 1024k NV SRAM (Nonvolatile Static RAM) which ensures data retention without the need for a battery backup during power loss.
• Integrated Real-Time Clock: The device includes a full-function, binary-coded decimal (BCD) real-time clock/calendar with an alarm feature, programmable square wave output, and 114 bytes of user-accessible NV RAM for control and status.
• Data Integrity: The nonvolatile timekeeping RAM ensures that data is not lost when power is removed, thanks to the internal lithium energy source that maintains data and clock operations for over 10 years in the absence of external power.
• Speed: With an access time of 150ns, the DS1244Y-150 ensures swift data retrieval and storage, making it an efficient choice for time-sensitive applications.
• Automatic Backup: An integrated precision quartz crystal and lithium energy source automatically switch to backup mode during power failures, ensuring continuous timekeeping and data preservation.
• Compatibility: The device is designed with a standard JEDEC 32-pin DIP (Dual In-line Package), making it compatible with existing RAM sockets for easy integration.

Applications

The DS1244Y-150 is versatile and can be used in a wide range of applications where data integrity and accurate timekeeping are critical. It is ideal for use in embedded systems, utility meters, industrial controllers, point-of-sale terminals, and other systems that require battery-backed RAM and an RTC.

Conclusion

With its robust feature set and reliable performance, the Maxim Integrated DS1244Y-150 Nonvolatile Timekeeping RAM is an excellent choice for designers looking for a memory solution that will preserve data and maintain accurate time even during power outages. Its ease of integration, long-term reliability, and support for a wide range of applications make it a valuable component in any system where data and time must be protected.
