Organized as 256 x 4 bits, it stores small configuration parameters, calibration constants, or serialisation data in a non-volatile array. The 2 µs access time keeps read cycles tight enough that a typical MCU polling the bus does not need extra wait states. Supply range spans 3V to 5.25V, covering both 3.3V and 5V logic rails without a level translator. ## Through-hole footprint, industrial temperature range The DS28E07+ comes in a TO-92-3 through-hole package (TO-226-3, TO-92-3 (TO-226AA)), the same three-lead outline used by many small-signal transistors and temperature sensors. It drops into a standard 0.1-inch pitch PCB footprint with no reflow profile needed — hand-solder or wave-solder friendly. The operating temperature range of -40°C to +85°C qualifies it for industrial environments, outdoor telecom cabinets, and factory-floor sensor nodes where commercial-grade parts drift out of spec. ## Active production, no end-of-life concern Maxim lists the DS28E07+ as Active on the product status. ROHS3 compliant per the compliance listing.","metaTitle":"Maxim DS28E07+ 1Kbit 1-Wire EEPROM, TO-92-3, 2 µs Access","metaDescription":"Maxim DS28E07+ 1Kbit 1-Wire EEPROM in TO-92-3 package, 2 µs access time, 3V to 5.25V supply, -40°C to +85°C.

The supply range of 3V to 5.25V includes 3.3V, so the part operates directly on a 3.3V rail. The 1-Wire interface uses a single data line with an open-drain driver and external pull-up; at 3.3V the logic thresholds are compatible with most 3.3V microcontrollers without level shifting."},{"question":"How many bytes can DS28E07+ store?","answer":"The DS28E07+ stores 1Kbit of non-volatile memory, organized as 256 x 4 bits. That equals 128 bytes of user-accessible storage (since 256 addresses × 4 bits = 1024 bits = 128 bytes)."},{"question":"What is the difference between DS28E07+ and DS2431?","answer":"The DS2431 is a 1Kbit 1-Wire EEPROM in an SOIC-8 package, while the DS28E07+ is the same 1Kbit density and 1-Wire interface but in a TO-92-3 through-hole package. The DS28E07+ also uses a 256 x 4 organization versus the DS2431's 256 x 4 as well — the primary difference is the package footprint and mounting style, not the memory array or protocol."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/DS28E07","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/DS28E07 when reusing this data.
