DS1743WP-120: High-Capacity NV SRAM with Integrated Battery

The DS1743WP-120 is a robust non-volatile (NV) static RAM product designed by Maxim Integrated to provide a reliable and durable data storage solution. This high-capacity memory device integrates 256k x 8 of SRAM with a self-contained lithium energy source, ensuring data retention without the need for an external battery. The seamless integration of the battery within the memory module provides a compact and efficient design, making it an ideal choice for a wide range of applications that require data integrity after power loss.

One of the key features of the DS1743WP-120 is its ability to automatically switch from a write/read operation to non-volatile storage when power drops below a critical threshold. This ensures that all data is preserved in the event of a power failure. The device also includes a write-protect function, which prevents accidental data overwrites or corruption during power-down cycles.

The DS1743WP-120 operates over a wide temperature range, making it suitable for use in harsh industrial environments. Its power-fail protection is guaranteed over the full industrial temperature range (-40°C to +85°C), ensuring reliable performance under extreme conditions. The device is housed in a 34-pin PowerCap Module (PCM) package, which is specifically designed to be surface-mounted on a printed circuit board. This packaging not only provides a space-saving solution but also offers enhanced durability and resistance to environmental factors.

With a fast access time, the DS1743WP-120 is capable of meeting the demands of high-speed microprocessors and can easily be interfaced with most CPUs. Its JEDEC standard pinout allows for easy integration into existing designs without the need for significant board modifications.

In summary, the DS1743WP-120 from Maxim Integrated is a high-performance, non-volatile SRAM module that offers a long-term data storage solution with integrated battery backup. Its automatic power-fail protection, wide temperature range, and robust packaging make it an excellent choice for applications in telecommunications, industrial control, and any other systems where data integrity is paramount.
