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.
