1-Wire EEPROM


Maxim's DS28E05 is a 112-byte, user-programmable EEPROM

The DS28E05 is a 112-byte user-programmable EEPROM organized as 7 pages of 16 bytes each. Memory pages can be individually set to write protected or EPROM emulation mode through protection byte settings. Each part has its own guaranteed unique 64-bit ROM identification number (ROM ID) that is factory programmed into the chip. The DS28E05 communicates over Maxim Integrated'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.
