DS28E05R+T

DS28E05R+T is a 112-byte user-programmable EEPROM organized into 7 pages of 16 bytes each. Memory pages can be individually set to write protected or EPROM emulation mode through protection byte settings. It has its own guaranteed unique 64-bit ROM identification number (ROM ID) that is factory-programmed into the chip. The DS28E05 communicates over Analog Device's single contact 1-Wire® interface at overdrive speed with the ROM ID acting as node address in the case of a multiple-device 1-wire network. Typical applications include accessory/PCB identification, medical sensor calibration data storage, analogue sensor calibration, and aftermarket management of consumables.
