DS28E05 1-Wire EEPROM
General Description
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 identi-
fication 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.
