Maxim Integrated DS1245Y-70+ Nonvolatile Memory

The Maxim Integrated DS1245Y-70+ is a high-performance, 1024k Nonvolatile SRAM with a battery monitor that provides reliable data retention while eliminating the complexities, overhead, and system level reliability problems caused by external batteries. This memory module is a perfect solution for a wide range of applications that require the preservation of data during power loss without the need for a traditional battery backup.

Designed with sophistication, the DS1245Y-70+ integrates an array of 1,048,576 x 8 nonvolatile static RAM, a fully automatic power-fail chip enable control circuit, and a high-reliability lithium battery all in a single monolithic chip. The access time of 70ns makes this device not only reliable but also swift in performance, suitable for high-speed microprocessor systems.

The unique feature of this product is its power-fail control circuit which automatically switches to the battery supply when power failure is detected, ensuring that the memory contents remain intact and uncorrupted. This seamless transition is crucial for mission-critical data logging and real-time applications where data integrity is paramount.

Another key aspect of the DS1245Y-70+ is its Write Protection feature. It includes a write protect switch that when enabled, prevents data from being written to the memory, thereby providing an additional layer of security against inadvertent data corruption.

The DS1245Y-70+ is packaged in a 32-pin EDIP (Encapsulated Dual In-line Package) which is known for its durability and ease of handling. The device operates over an industrial temperature range, making it suitable for use in environments with extreme temperature variations.

In summary, the Maxim Integrated DS1245Y-70+ offers a combination of speed, reliability, and convenience. It is an ideal choice for applications such as data collection devices, industrial control systems, utility meters, medical equipment, and any other system that requires data persistence without the maintenance or replacement issues associated with battery-backed SRAM.
