Maxim Integrated DS2502P+T&R - 1Kb Add-Only Memory

The DS2502P+T&R from Maxim Integrated is a high-quality, non-volatile memory chip that offers a 1Kb storage capacity designed for applications requiring a permanent and secure storage of data. This add-only memory (AOM) device is part of Maxim's renowned family of 1-Wire® devices, which provide a simple and cost-effective interface for data communication and power through a single contact.

The DS2502P+T&R is equipped with a unique, factory-lasered and tested 64-bit registration number, which ensures absolute traceability because no two parts are alike. This registration number serves as a node address in a 1-Wire network, which allows for multiple devices to share the same data line. The device's add-only feature makes it ideal for storing sensitive data that needs to be protected from alterations or tampering, such as calibration constants, board identification, and product revision status.

With its wide operating range of -40°C to +85°C, the DS2502P+T&R offers reliable performance even in harsh environments. The device is available in a compact TO-92 package, making it suitable for space-constrained applications. Additionally, the product is supplied in a tape and reel format (T&R), which facilitates automated pick-and-place manufacturing processes, ensuring efficient assembly and production throughput.

Key features of the DS2502P+T&R include:

• 1024 bits of 5V EEPROM memory
• Unique 64-bit serial number for network identification
• Minimalist 1-Wire interface for communication and power
• High-reliability data retention
• Write-protect feature to ensure data integrity
• Compact TO-92 packaging suitable for various applications

This memory device is perfect for use in applications such as accessory/cartridge identification, after-market management of consumables, and any system that requires a robust audit trail. With its ability to store data permanently and securely, the DS2502P+T&R is an excellent choice for designers and engineers looking for a dependable and cost-effective solution for their data storage needs.
