Organized as 256 x 4 bits, it provides non-volatile storage for calibration constants, serial numbers, or system configuration data. ## Active production, no obsolescence concern ROHS3 compliant, it ships in Tape & Reel or Cut Tape options, so it fits both prototype builds and volume production without procurement risk.","metaTitle":"DS2431Q+T&R 1Kbit 1-Wire EEPROM, 2 µs access, 6-TDFN","metaDescription":"Maxim DS2431Q+T&R 1Kbit non-volatile EEPROM with 1-Wire interface, 2 µs access time, industrial temp range -40°C to 85°C, 6-TDFN package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Technology":"EEPROM","Access Time":"2 µs","Memory Size":"1Kbit","Memory Type":"Non-Volatile","Memory Format":"EEPROM","Mounting Type":"Surface Mount","Package / Case":"6-WDFN Exposed Pad","lifecycle_stage":"eol_hot","Memory Interface":"1-Wire®","Memory Organization":"256 x 4","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"6-TDFN (3x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.12","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.12000","currency":"USD"},{"qty":10,"price":"$1.93500","currency":"USD"},{"qty":25,"price":"$1.88280","currency":"USD"},{"qty":50,"price":"$1.87320","currency":"USD"},{"qty":100,"price":"$1.67450","currency":"USD"},{"qty":250,"price":"$1.66964","currency":"USD"},{"qty":500,"price":"$1.64444","currency":"USD"},{"qty":1000,"price":"$1.57463","currency":"USD"},{"qty":2500,"price":"$1.51646","currency":"USD"},{"qty":5000,"price":"$1.46604","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/DS2431.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is DS2431Q+T&R lead-free and ROHS compliant?","answer":"Yes, the DS2431Q+T&R is ROHS3 Compliant, meaning it meets the latest ROHS directive without exemptions. No lead or restricted substances above the threshold."},{"question":"Can DS2431Q+T&R operate at 3.3V and what is the 1-Wire interface timing?","answer":"The DS2431 operates from a 2.8V to 5.25V supply, so 3.3V is within range. The 1-Wire interface uses a single data line with a timing slot of approximately 60 µs for standard speed; the 2 µs access time refers to the read cycle from the memory array to the output register. Detailed timing parameters are in the datasheet, but the key takeaway is that standard 1-Wire host controllers (e.g., Maxim DS2482 or bit-banged GPIO) work directly."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/DS2431QTR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/DS2431QTR when reusing this data.
