The DS1225AD-170+ from Maxim Integrated is a 64k Nonvolatile SRAM designed to provide reliable data retention while eliminating the complexities, overhead, and system level reliability problems caused by battery-backed SRAM. With a fully static operation and a wide voltage range of 4.5V to 5.5V, this memory module is ideal for a wide range of demanding applications.

The DS1225AD-170+ offers an organized memory structure of 8K x 8, allowing for efficient data storage and easy integration into a variety of systems. This device features a nonvolatile quantum trap storage element for each memory cell which ensures data retention without the need for a battery. This makes it a highly reliable choice for critical data storage applications that require long-term data retention without periodic replacement of a battery.

Data is automatically transferred to the nonvolatile storage upon power-down and is automatically recalled to static RAM upon power-up, ensuring data integrity and reducing the need for routine checks and manual intervention. This process is transparent to the user and requires no additional control pins or timing sequences, simplifying the design and reducing the risk of data loss.

The DS1225AD-170+ operates over an industrial temperature range (-40°C to +85°C), making it suitable for use in harsh environments. Its access time of 170ns allows for high-speed data access, which is critical for real-time applications. The device also features a JEDEC standard 28-pin DIP package, which is widely accepted and provides ease of integration into existing designs.

Maxim Integrated's commitment to quality ensures that the DS1225AD-170+ is a reliable and durable choice for applications that cannot afford to lose data. This includes industrial controls, medical equipment, and other mission-critical systems where data integrity and reliability are paramount.

For designers and engineers looking for a robust, nonvolatile memory solution without the long-term concerns associated with battery-backed SRAM, the DS1225AD-170+ presents an ideal solution.
