Rack Card Calibration and Control – the controller in a module-based rack or chassis system often needs to identify what cards are installed, monitor key metrics like temperature, and track hot-swapped units. The 1 – Wire® memory, I/O, and temperature-sensor products solve this problem by providing a unique identity for every module in the system. The 1 – Wire® devices typically used include the DS2413, DS28EA00, DS2502, DS2505, DS2431, DS28EC20, DS2433, DS28E04, and DS28E01. PCB identification and authentication – factory-administered 64-bit serialization with embedded memory provides PCB/product labeling and storage of product information. Programmable features like OTP (One-Time Programmable) mode and write protection combine with SHA-1 based secure authentication to ensure that critical data cannot be altered once it is programmed. Storage of product characteristics, PCB hardware/software revision, maintenance records, and calibration constants are examples of typical usage. The 1 – Wire® devices typically used include the DS2401, DS2411, DS1963S, DS1992L, DS2502-E48, DS2502-E64, DS1982, DS1985, DS2431, DS28EC20, DS2433, DS28E01, and DS1961S. Accessory/Peripheral Identification and Control – typical applications include battery- pack and power-adapter identification, LED control, TEDS (Transducer Electronic Data Sheet) sensor identification/control, and consumable identification/control. The 1 – Wire® devices typically used include the DS2401, DS2411, DS2413, DS2502, DS2505, DS2431, DS28EC20, DS2433, and DS28E01. IP Protection, Secure Feature Control Clone Prevention – authentication solutions help OEMs (Original Equipment Manufacturers) protect product development and research 31
and development (R&D) investments by preventing low-quality knockoffs from entering the marketplace. Authentication solution options range from customization of the unique serial number factory-lasered into each device (providing controlled procurement access) to secure crypto-strong ISO/IEC 10118-3 SHA-1 based challenge and response for bi- directional authentication. The 1 – Wire® devices typically used include the DS2401, DS2411, DS1963S, DS1993L, DS1995L, DS1996L, DS2431, DS28EC20, DS28E01, and DS1961S. Consumer electronics – the types of 1 – Wire® devices used in consumer electronics include those of identification only (DS2401 and DS2411), identification plus control (DS2450), identification plus time (DS2417 and DS1904L), identification plus EEPROM (DS28EC20 and DS2431), and identification plus SHA – 1 secure EEPROM (DS28E01). Access control – the types of 1 – Wire® devices used for access control include those of identification only (DS1990A/DS1990R), identification plus NV SRAM (DS1992L, DS1993L, DS1995L, DS1996L), and identification plus EEPROM (DS1971, DS1972, DS1973). Electronic cash – the type of 1 – Wire® devices used for electronic cash tokens include those of identification plus NV SRAM (DS1963S) and identification plus SHA – 1 Secure EEPROM (DS1961S). Gaming devices – the type of 1 – Wire® devices used for the gaming industry include those of identification plus EEPROM (DS1977) due to high capacity (32KB) and password protection. 32
