The Maxim Integrated DS1230WP-150+ is a high-performance, 256k Nonvolatile SRAM designed to deliver reliable data retention while eliminating the complexities, overhead, and system level reliability problems caused by battery-backed SRAM. With a memory capacity of 32k x 8, this device integrates a quantum trap storage element with each of the 262,144 SRAM cells, ensuring data persistence without the need for a battery.

Key Features

• Memory Size: 256k-bit (32k x 8)
• Speed: 150ns access time, providing quick read and write operations for high-performance applications.
• Package: Housed in a durable 28-pin, 330 mils SO package that is surface-mountable and suitable for automated assembly processes.
• Power: A wide voltage range of 4.5V to 5.5V, making it compatible with standard 5V systems.
• Write Protection: Includes a write protect feature that prevents accidental data alteration during power transitions.
• Automatic Recall: Upon power-up, the internal circuitry automatically transfers data from the nonvolatile elements to the SRAM cells (recall), ensuring the availability of the stored data.
• Automatic Store: When power begins to fail, the device automatically saves the SRAM data to nonvolatile elements (store), ensuring data integrity.
• Endurance: Offers unlimited read and write cycles to the SRAM, and a minimum of 1,000,000 store cycles to the nonvolatile elements.
• Data Retention: Guaranteed data retention for a minimum of 10 years at the industrial temperature range.

Applications

The DS1230WP-150+ is ideal for a wide range of applications that require reliable and durable nonvolatile memory. It is especially well-suited for use in systems that must preserve critical data during power loss, such as:

• Industrial control systems
• RAID systems
• Medical equipment
• POS terminals
• Telecommunications equipment

With its robust design and integrated nonvolatility, the Maxim Integrated DS1230WP-150+ provides a dependable memory solution for systems that cannot afford to lose data. It is an excellent choice for designers seeking a maintenance-free, long-term storage option for their critical data.
