1-Wire serial EEPROM for single-contact bus designs
The DS24B33G+T&R is a 4Kbit serial EEPROM from Analog Devices that communicates over a 1-Wire interface, meaning data and power share a single data line plus ground. With a 2 µs access time, the read-cycle timing is set by the 1-Wire bus protocol overhead rather than the memory array itself; the part keeps up with the standard 15.4 kbps or overdrive 125 kbps 1-Wire communication rates without adding wait states.
Supply range and temperature grade for field deployment
The 256 x 16 memory organization means the smallest writable unit is a 16-bit word, which is typical for serial EEPROMs and aligns with the 1-Wire protocol's block-write granularity.
Housed in a 2-SFN package measuring 6x6 mm, the DS24B33G+T&R is a surface-mount device with a small footprint. The mounting type is surface mount, so the PCB layout should follow the recommended land pattern for the 2-SFN package to ensure proper solder joint formation and thermal dissipation.
