The Analog Devices DS2502 is a 1Kb Electrically Programmable Read-Only Memory (EPROM) designed for adding traceability and relevant information to individual systems. It features a unique, factory-lasered 64-bit registration number for absolute traceability, composed of an 8-bit family code, a 48-bit serial number, and an 8-bit CRC tester.
The EPROM is partitioned into four 256-bit pages, allowing for random access of packetized data. Each memory page can be permanently write-protected to prevent tampering. This device functions as an add-only memory, enabling additional data programming without disturbing existing information. Its architecture supports software patching by superseding an old page with a newly programmed one.
The DS2502 utilizes a minimalist 1-Wire interface, reducing control, address, data, power, and programming signals to a single data pin. This interface connects directly to a single port pin of a microprocessor and communicates at speeds up to 16.3kb per second. A built-in multidrop controller ensures compatibility with other 1-Wire Net products.
This memory IC offers robust system performance with a wide operating voltage range of 2.8V to 6.0V and an operating temperature range of -40°C to +85°C. It requires zero standby power. Programming is supported at 11.5V to 12.0V within a temperature range of -40°C to +50°C. The DS2502 is available in various package types, including TO-92, SFN, 8-pin SO, SOT-23, TSOC, and WLP surface mount packages.
