General Description
The DS24B33 is a 4096-bit, 1-Wire ? EEPROM orga-
nized as 16 memory pages of 256 bits each. Data is
written to a 32-byte scratchpad, verified, and then
copied to the EEPROM memory. The DS24B33 commu-
nicates over a single-conductor 1-Wire bus. The com-
munication follows the standard 1-Wire protocol. Each
device has its own unalterable and unique 64-bit regis-
tration number that is factory programmed into the chip.
The registration number is used to address the device
in a multidrop 1-Wire net environment. The DS24B33 is
software compatible to the DS2433.
