Maxim Integrated DS2501-UNW: High-Capacity Add-Only Memory

The DS2501-UNW from Maxim Integrated is a unique add-only memory device that offers a robust and secure way to store data in a tamper-proof manner. This innovative product is perfect for applications that require a permanent and non-alterable record of data, such as calibration, equipment configuration, usage logging, or any other critical data that must be preserved over a product's lifetime.

Featuring a 1k-bit Electrically Programmable Read Only Memory (EPROM), the DS2501-UNW is partitioned into four 256-bit pages. Each page can be individually and permanently write-locked to prevent any alterations once the data has been written. This ensures that the information stored on the chip remains reliable and unaltered, providing a trustworthy source of data for sensitive applications.

The device operates over a wide voltage range of 2.8V to 6.0V and is designed to function in harsh environments, making it suitable for a wide variety of industrial and commercial applications. Its compact TO-92 package allows it to be easily integrated into system designs where space is at a premium.

The DS2501-UNW incorporates Maxim's renowned 1-Wire® interface, which facilitates communication through just one data line (plus ground) for simple and cost-effective system integration. This feature enables the device to be connected in a multi-drop configuration, allowing multiple units to share the same 1-Wire bus, thereby reducing the complexity and cost of the wiring harness.

Additionally, each DS2501-UNW is factory-lasered with a unique 64-bit registration number that serves as an unalterable device identifier. This unique ID ensures that the device, and thus the data it holds, can be authenticated and traced back to its origin, adding an extra layer of security to the system.

Whether it's for warranty systems, medical devices, or any other critical data storage application, the DS2501-UNW is a reliable choice for maintaining the integrity of your data over the long term. With its robust design and secure features, Maxim Integrated's DS2501-UNW represents a state-of-the-art solution for permanent data storage needs.
