It stores 256 x 8 bits of non-volatile data, organized for byte-level reads and writes. The 900 ns access time is fast enough for most microcontroller parameter-retrieval loops, and the 5 ms write cycle per word or page sets the timing budget for firmware update routines. The supply range spans 1.7V to 5.5V, which lets this part drop into both 1.8V and 3.3V logic domains without a level translator. ## Wide supply — the deciding spec The 1.7V minimum supply is the main reason to pick the 24AA02T-I/SN over the 24LC025T-I/ST, which requires 2.5V minimum. In a 1.8V-only system — battery-powered IoT nodes, single-cell Li-ion designs — the 24AA02T-I/SN runs directly off the rail. The 24LC025T-I/ST needs a boost converter or a second regulator, adding cost and board area. ## Surface-mount footprint and tape options","metaTitle":"Microchip 24AA02T-I/SN 2Kbit I2C EEPROM, 400 kHz, 8-SOIC","metaDescription":"Microchip 24AA02T-I/SN 2Kbit I2C EEPROM, 400 kHz bus, 1.7V-5.5V supply, 900 ns access, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Technology":"EEPROM","Access Time":"900 ns","Memory Size":"2Kbit","Memory Type":"Non-Volatile","Memory Format":"EEPROM","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","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-SOIC","Write Cycle Time - Word, Page":"5ms"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3","priceTiers":[{"qty":1,"price":"$0.30000","currency":"USD"},{"qty":3300,"price":"$0.30000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/09fd1810eb9252a439d4d616af217ead.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/24AA02T-I%2FSN/alternatives.json"},"ai":{"faq":[{"question":"Is 24AA02T-I/SN equivalent to 24LC02T?","answer":"The 24AA02T-I/SN and 24LC02T are functionally equivalent in memory size (2Kbit), interface (I2C at 400 kHz), package (8-SOIC), and timing (900 ns access, 5 ms write). The key difference is the supply voltage: the 24AA series operates down to 1.7V, while the 24LC series requires 2.5V minimum.
