Maxim Integrated DS2502P-5P1 - 1Kb Add-Only Memory

The Maxim Integrated DS2502P-5P1 is a unique, 1Kb add-only memory module designed for applications requiring a low-cost, nonvolatile memory with a permanent and unalterable storage system. This device integrates 1024 bits of EPROM with a factory-programmed, 48-bit serial number, and an additional 8-bit Family Code (01h). Each DS2502P-5P1 has a distinct serial number which ensures absolute traceability, making it an ideal choice for product identification and authentication purposes.

Built with rugged construction, the DS2502P-5P1 is encapsulated in a compact TO-92 package, offering a space-saving solution for PCBs with limited real estate. It operates over a wide voltage range of 2.8V to 6.0V and is characterized for operation from -40°C to +85°C, ensuring reliability and performance under extreme conditions.

The device supports the 1-Wire communication protocol, which allows for a simple two-wire interface (data and ground) for communication with a host controller. This feature simplifies the system design by reducing the number of wires required for data transmission, which is particularly beneficial in applications where minimal wiring is crucial.

Key features of the DS2502P-5P1 include:

• 1024 bits Electrically Programmable Read-Only Memory (EPROM) organized as four pages of 256 bits each
• Unique, factory-lasered, and tested 48-bit registration number ensures error-free device selection and absolute traceability
• Built-in multidrop controller ensures compatibility with other devices in the 1-Wire network
• Low-cost TO-92 package
• High-reliability data retention

The DS2502P-5P1 is perfect for applications that require data to be stored during manufacturing and remain intact throughout the product's life. This includes use cases such as medical device calibration data storage, consumable authentication, warranty tracking, or any other application where the integrity of the data is paramount.

Whether you're developing a new product or upgrading an existing system, the Maxim Integrated DS2502P-5P1 provides a secure and cost-effective solution for permanent data storage needs.
