Maxim Integrated DS2502P-E48+TR EEPROM

The Maxim Integrated DS2502P-E48+TR is a high-quality 1Kb Add-Only Memory, part of the renowned 1-Wire® family of devices. This product offers a unique and cost-effective solution for storing data that must be updated occasionally, such as identification and calibration information. The DS2502P-E48+TR comes in a TO-92 package and is sold in tape and reel form, which is ideal for automated assembly processes, denoted by the "+TR" suffix.

Designed with an innovative 1-Wire interface, the DS2502P-E48+TR requires only a single data line and a ground return for communication. This simplifies system design and reduces the overall component count. Furthermore, each DS2502P-E48+TR contains a unique, factory-lasered and tested 64-bit registration number that ensures absolute traceability. This feature is invaluable for applications where individual device identification is necessary, such as in accessory or consumable authentication.

The memory in the DS2502P-E48+TR is organized as four memory pages of 32 bytes each. The first page is typically used for the device's registration number and a write-once, read-multiple times application data. The remaining pages can be used for user data storage, providing flexibility for various data logging requirements. The Add-Only structure of the memory ensures that once data has been written, it cannot be altered or erased, thereby preserving the integrity of the data.

This EEPROM operates over a wide voltage range of 2.8V to 6.0V and features a working temperature range of -40°C to +85°C, making it suitable for harsh environments. Its high-reliability and endurance make the DS2502P-E48+TR an excellent choice for a wide array of applications, including medical devices, consumer electronics, and industrial equipment.

Maxim Integrated's commitment to quality ensures that the DS2502P-E48+TR meets the stringent requirements for data retention and endurance. Users can trust this product for secure and reliable non-volatile storage of critical data.
