Maxim Integrated DS1245AB-100+ Nonvolatile SRAM

The Maxim Integrated DS1245AB-100+ is a high-performance, 1024k Nonvolatile SRAM designed to deliver a reliable data storage solution that combines the access speed of static RAM with the non-volatility of Flash. The device features a 32-pin, 5V parallel EEPROM with a 100 ns access time, making it suitable for a wide range of applications where data integrity and fast access are paramount.

This nonvolatile SRAM is equipped with an internal lithium battery that ensures data retention for a minimum of 10 years in the absence of power. This unique design allows the DS1245AB-100+ to automatically switch to the battery supply during a power failure, thus preserving all data in the memory. This seamless transition to battery backup mode makes it an ideal choice for critical data storage applications where data loss is not acceptable.

The DS1245AB-100+ offers a simple memory interface that can be easily integrated into existing systems without the need for additional hardware or complex software. Its compatibility with industry-standard microprocessor buses allows for a straightforward drop-in replacement for traditional SRAMs, while providing the added benefit of non-volatility.

Key features of the DS1245AB-100+ include:

• 1M (128k x 8) Nonvolatile SRAM
• 100 ns access time
• Automatic battery backup and write protection during power failures
• Minimum of 10 years of data retention in the absence of power
• Unlimited write cycles and read cycles
• 5V ±10% power supply
• Compatible with JEDEC standard byte-wide 32-pin DIP
• Commercial and industrial temperature ranges

Applications for the DS1245AB-100+ span across various fields that require robust, long-term data retention without the need for external batteries or periodic data refreshing. These include industrial control systems, utility meters, medical devices, point-of-sale terminals, and other embedded systems.

Maxim Integrated's commitment to quality ensures that the DS1245AB-100+ is a reliable component for preserving critical data and maintaining system integrity across a variety of demanding applications.
