The Maxim Integrated DS1230AB-70IND+ is a highly reliable, 256k Nonvolatile (NV) SRAM module that combines the convenience of static RAM with a non-volatile data retention capability. This makes it an ideal memory solution for systems requiring the speed of SRAM and the permanence of non-volatile storage, without the need for a battery to maintain the data.

Key Features

• Capacity: 256k (32k x 8-bit) provides ample storage for critical data.
• Access Time: 70ns access time ensures fast data retrieval, suitable for high-performance applications.
• Nonvolatile Technology: Data is maintained without power using the internal lithium energy source and a self-contained energy source and control circuitry, which constantly monitors V<sub>CC for an out-of-tolerance condition.
• Automatic Write Protection: When V<sub>CC falls below the minimum V<sub>CC threshold, the device write-protects itself, ensuring data integrity during power loss.
• High Reliability: Endurance of at least 1,000,000 write cycles and data retention of over 10 years.
• Industrial Temperature Range: Rated for operation between -40°C and +85°C, making it suitable for use in harsh environments.
• Package: Provided in a 28-pin, 600-mil DIP (DS1230AB) package for easy integration into a variety of circuit designs.

Applications

The DS1230AB-70IND+ is designed for applications that require fast and reliable nonvolatile memory. Its rugged design and extended temperature range make it suitable for industrial control systems, utility meters, medical equipment, and other applications where data integrity and system uptime are critical.

Easy Integration

Integration into existing designs is simplified, thanks to the pin compatibility with standard static RAMs. This allows designers to upgrade their systems with nonvolatile memory without the need to redesign the power supply or make significant PCB changes.
