It stores configuration parameters, calibration constants, or small lookup tables in designs where non-volatile memory is needed but the density requirement stays modest. The 8-DIP through-hole package (0.300\" body) is the go-to form factor for breadboarding, legacy board rework, and low-volume production where socketing or hand-soldering is the norm. The 900 ns access time at 400 kHz leaves setup margin before the next SCL edge. The through-hole PDIP package is not the first choice for high-vibration environments — a socket with a retention clip or conformal coating helps — but for benchtop instrumentation, HVAC controllers, and retrofit boards it is exactly what the rework tech wants to see. Microchip lists the 34AA02-I/P as Active. The ROHS3 compliance covers current EU and UK regulatory requirements without an exemption expiry.","metaTitle":"Microchip 34AA02-I/P EEPROM, 2Kbit I²C, 400 kHz, 8-DIP","metaDescription":"Microchip 34AA02-I/P 2Kbit I²C EEPROM, 900 ns access time, 1.7V–5.5V supply, -40°C to 85°C, 8-DIP through-hole.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Package":"Tube","Technology":"EEPROM","Access Time":"900 ns","Memory Size":"2Kbit","Memory Type":"Non-Volatile","Memory Format":"EEPROM","Mounting Type":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","Clock Frequency":"400 kHz","lifecycle_stage":"eol_hot","Memory Interface":"I²C","Voltage - Supply":"1.7V ~ 5.5V","Memory Organization":"256 x 8","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-PDIP","Write Cycle Time - Word, Page":"5ms"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.39","priceTiers":[{"qty":1,"price":"$0.39000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/50a3de3d02ecc5d131490c6ae417eb68.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/34AA02-I%2FP/alternatives.json"},"ai":{"faq":[{"question":"What are the cross-reference alternatives to 34AA02-I/P?","answer":"The closest functional alternative in a through-hole DIP package is the 24AA01-I/P (1 Kbit, same I²C interface, same supply range and temperature grade). The 24AA01-I/P halves the density to 128 x 8 and has a longer access time of 3500 ns, so a firmware change to the memory map and a timing review are needed. For a drop-in 2 Kbit replacement, the AT34C02C-THDD-T matches the density and access time but comes in a surface-mount package — not a pin-compatible swap for the 8-DIP footprint."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/34AA02-I-P","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/34AA02-I-P when reusing this data.
