It is organized as 16K x 1 bit and packaged in a through-hole TO-92-3 (TO-226AA) case. The 1-Wire bus reduces interconnect to one data line plus ground, making this part a natural fit for add-on identification, calibration constant storage, or configuration data in systems where a separate I²C or SPI bus is not available or where cabling must be minimized. Typical deployment includes accessory recognition in battery packs, printer cartridges, medical probes, and industrial sensors that need a small, non-volatile, factory-locked memory block. ## 15 µs access — what it means for the bus The 15 µs access time is the time from the end of the read command to data valid on the 1-Wire bus. This is slow compared to parallel or SPI memory, but the 1-Wire protocol runs at typical bit rates of 15-90 kbps, so the access time is not a bottleneck for the small data payloads this part is designed for — a few tens of bytes per read transaction. The real constraint is the OTP nature: once a byte is programmed (with the 1-Wire programming command), it cannot be erased or rewritten. Plan the write process carefully before assembly. ## OTP memory: no field updates possible Because the DS2505+ uses EPROM - OTP technology, every memory cell can be written exactly once. There is no erase cycle, no wear-leveling, and no reprogramming. This makes the part ideal for permanent serialization, cryptographic key storage, or factory-calibration data that must not be altered after deployment. For the procurement side, this means the programming step must happen before the part is soldered — either pre-programmed by a distributor or programmed in-house with a 1-Wire programmer before placement. The industrial temperature range (-40°C to 85°C) supports outdoor and engine-bay environments where the data must remain stable over the product life. ## Lifecycle and sourcing The DS2505+ carries an Active lifecycle status from Maxim Integrated (now part of Analog Devices).","metaTitle":"DS2505+ 1-Wire EPROM, 16Kbit, 15 µs, TO-92","metaDescription":"Maxim DS2505+ 16Kbit 1-Wire EPROM, 15 µs access, industrial temp -40°C to 85°C, TO-92-3 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Bulk","Technology":"EPROM - OTP","Access Time":"15 µs","Memory Size":"16Kbit","Memory Type":"Non-Volatile","Memory Format":"EPROM","Mounting Type":"Through Hole","Package / Case":"TO-226-3, TO-92-3 (TO-226AA)","lifecycle_stage":"eol_hot","Memory Interface":"1-Wire®","Memory Organization":"16K x 1","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"TO-92-3"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.76","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.76000","currency":"USD"},{"qty":10,"price":"$3.41500","currency":"USD"},{"qty":25,"price":"$3.34080","currency":"USD"},{"qty":50,"price":"$3.32300","currency":"USD"},{"qty":100,"price":"$2.97940","currency":"USD"},{"qty":250,"price":"$2.96856","currency":"USD"},{"qty":500,"price":"$2.86010","currency":"USD"},{"qty":1000,"price":"$2.71908","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/DS2505.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the memory size and organization of DS2505+?","answer":"The DS2505+ is a 16 Kbit EPROM organized as 16K x 1 bit.
