Maxim Integrated DS1249AB-70# Nonvolatile RAM

The DS1249AB-70# is a high-quality, nonvolatile memory module from Maxim Integrated, renowned for its reliability and durability in a wide range of applications. This particular product features a 1024k NV SRAM with a Phantom Clock, providing not only data storage but also timekeeping functionality, making it an ideal choice for systems requiring both memory and real-time clock capabilities.

This nonvolatile RAM operates at a voltage range of 4.5V to 5.5V and is characterized by its access time of 70ns, ensuring swift data retrieval and storage, which is crucial for high-speed operations. The integration of a lithium energy source and a quartz crystal within the module allows the DS1249AB-70# to maintain timekeeping and data storage for over 10 years in the absence of external power.

The DS1249AB-70# is designed with a 28-pin, 600-mil EDIP (Encapsulated Dual In-line Package) or JEDEC standard 32-pin TSOP (Thin Small-Outline Package), providing flexibility and ease of integration into a variety of system designs. The device features an automatic power-fail chip deselect and write-protection, ensuring data integrity during any unexpected power disruptions.

One of the key advantages of this nonvolatile RAM is its direct compatibility with industry-standard integrated circuit sockets and memory buses. This means that it can be easily integrated into existing designs without the need for significant redesigns, saving both time and resources for developers.

Users can also benefit from the self-contained subsystem, which includes the SRAM, real-time clock, power-fail control circuit, and battery, all in a single package. This integration simplifies the design process, reduces the number of components required on the board, and enhances the overall reliability of the system.

The DS1249AB-70# is suitable for a wide array of applications, including industrial control systems, utility meters, medical equipment, and any other system that requires nonvolatile memory with a built-in real-time clock. With its robust design and proven performance, the DS1249AB-70# from Maxim Integrated is a smart choice for designers looking for a reliable and long-lasting memory solution.
