It comes in a TO-92-3 through-hole package, the same three-lead can used for decades in identification and calibration memory applications. ## Memory organization and bus integration The 256 x 4 organization means the memory is arranged in 256 words of 4 bits each — a 1Kbit total. This is a non-volatile EEPROM, so data persists without power, and the 1-Wire interface requires only a single data line plus ground, which simplifies cabling in retrofit or field-upgrade scenarios. The TO-92-3 package (TO-226-3, TO-92-3 (TO-226AA)) is a standard through-hole footprint that can be hand-soldered or socketed. The part is manufactured by Analog Devices, a major semiconductor supplier with long-term support for the 1-Wire product line.","metaTitle":"DS2431+ 1Kbit 1-Wire EEPROM, TO-92-3, Active","metaDescription":"Analog Devices DS2431+ 1Kbit (256 x 4) 1-Wire EEPROM in TO-92-3. 2 µs access time, -40 to +85°C.
