Maxim Integrated DS2502AX-500: 1-Wire EEPROM

The DS2502AX-500 from Maxim Integrated is a high-quality, non-volatile memory device that utilizes the unique 1-Wire interface. At 1024 bits (128 bytes), this EEPROM provides a compact data storage solution, enabling the user to store calibration, user identification, product revision status, or any other type of data that must be preserved through power cycles.

Designed with versatility in mind, the DS2502AX-500 is encased in a robust TO-92 package, providing a durable external form factor that is suitable for a wide array of applications. Its small physical footprint makes it ideal for space-constrained environments where maintaining a low profile is critical.

One of the standout features of the DS2502AX-500 is its unique 1-Wire interface, which allows for communication through a single data line (plus ground) for both power and data transfer. This innovative design simplifies system wiring and minimizes the interface's footprint on the host controller, making it an excellent choice for systems where pin count or board space is at a premium.

The device is equipped with a factory-lasered registration number that includes a unique 48-bit serial number, an 8-bit CRC, and an 8-bit Family Code (09h). This ensures absolute traceability as no two parts are alike, allowing for secure identification and authenticity checks in your application.

Additional features of the DS2502AX-500 include:

• Reduces control, address, data, and power to a single data pin.
• Directly connects to a single port pin of a microprocessor and communicates at up to 16.3k bits per second.
• Wide voltage and temperature operating ranges, making it suitable for harsh environments.
• Low-cost TO-92 package that is highly reliable and easy to handle in PCB designs.

The DS2502AX-500 is perfect for applications that require a small, modifiable nonvolatile memory. Its applications range from medical devices to industrial automation, consumer electronics, and more. Maxim Integrated's commitment to quality ensures that this EEPROM will maintain data integrity and provide reliable performance for the lifetime of your product.
