It stores non-volatile configuration, serialization, or calibration constants in a small 6-TSOC surface-mount package. The 1-Wire interface means only one GPIO and one pull-up resistor are needed on the host side, which simplifies PCB routing in space-constrained designs like sensor modules, battery packs, or accessory identification. Access time is 15 µs, which sets the read-cycle timing for the host firmware — the 1-Wire protocol handles the transaction at the bit level, so the 15 µs figure governs the time slot width for reading each bit. The part operates over -40°C to 85°C, covering industrial and outdoor telecom environments. ## Memory organization — what 256 bits buys you 32 bytes of EEPROM, organized as 32 x 8 bits, accessed one byte at a time over the 1-Wire bus.","metaTitle":"DS2430AP+T&R 256-bit 1-Wire EEPROM, 15 µs access, Active","metaDescription":"Maxim DS2430AP+T&R 256-bit serial EEPROM with 1-Wire interface, 15 µs access time, 32 x 8 organization, -40°C to 85°C, ROHS3 compliant.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Technology":"EEPROM","Access Time":"15 µs","Memory Size":"256bit","Memory Type":"Non-Volatile","Memory Format":"EEPROM","Mounting Type":"Surface Mount","Package / Case":"6-SMD, J-Lead","lifecycle_stage":"eol_hot","Memory Interface":"1-Wire®","Memory Organization":"32 x 8","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"6-TSOC"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.19","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.19000","currency":"USD"},{"qty":10,"price":"$2.86400","currency":"USD"},{"qty":25,"price":"$2.81960","currency":"USD"},{"qty":50,"price":"$2.81200","currency":"USD"},{"qty":100,"price":"$2.51270","currency":"USD"},{"qty":250,"price":"$2.43016","currency":"USD"},{"qty":500,"price":"$2.42130","currency":"USD"},{"qty":1000,"price":"$2.25466","currency":"USD"},{"qty":4000,"price":"$2.10868","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/DS2430A.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the memory size and organization of DS2430AP+T&R?","answer":"The DS2430AP+T&R has 256 bits of EEPROM organized as 32 bytes x 8 bits (32 x 8).
