The DS2502S+T&R is a 1Kbit Electrically Programmable Read-Only Memory (EPROM) integrated circuit designed for adding traceability and relevant information to individual systems. It offers 1024 bits of memory, partitioned into four 256-bit pages, with page-level write protection to prevent tampering.
This device utilizes a minimalist 1-Wire interface, reducing control, address, data, power, and programming signals to a single data pin. It communicates directly with a microprocessor at speeds up to 16.3kb per second and includes a built-in multidrop controller for compatibility with other 1-Wire Net products. The operating voltage range is 2.8V to 6.0V, with zero standby power required.
Programming occurs at 11.5V to 12.0V within a temperature range of -40°C to +50°C. The DS2502S+T&R is suitable for a wide operating temperature range of -40°C to +85°C. It is supplied in an 8-SOIC surface mount package, facilitating integration into various electronic designs.
Key features include a guaranteed unique 64-bit ROM ID for absolute traceability, consisting of an 8-bit family code, a 48-bit serial number, and an 8-bit CRC tester. The add-only memory architecture allows for new data to be programmed without disturbing existing data, and software can patch data by superseding old pages with new ones.
