The 450 ns access time is the read-cycle window the master sees; at 1 MHz SCL, each bit is 1 µs wide, so 450 ns leaves comfortable setup-and-hold margin on the bus. The 5 ms page/word write cycle time is the period the EEPROM holds SCL low during a write — firmware needs to account for that delay before starting the next transaction. Surface-mount only — no through-hole variant in this order code.","metaTitle":"Microchip 24FC04T-I/MUY 4Kbit I²C EEPROM, 1 MHz, 1.7V-5.5V","metaDescription":"Microchip 24FC04T-I/MUY 4Kbit serial EEPROM, I²C interface, 1 MHz clock, 450 ns access, 1.7V-5.5V supply, -40°C to 85°C, 8-UDFN package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Technology":"EEPROM","Access Time":"450 ns","Memory Size":"4Kbit","Memory Type":"Non-Volatile","Memory Format":"EEPROM","Mounting Type":"Surface Mount","Package / Case":"8-UFDFN Exposed Pad","Clock Frequency":"1 MHz","lifecycle_stage":"eol_hot","Memory Interface":"I²C","Voltage - Supply":"1.7V ~ 5.5V","Memory Organization":"256 x 8 x 2","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-UDFN (2x3)","Write Cycle Time - Word, Page":"5ms"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.26","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.26000","currency":"USD"},{"qty":5000,"price":"$0.25500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/37d8b5fcdbda24eb6e5509679260da94.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does the 24FC04T-I/MUY support 1 MHz I²C?","answer":"Yes, the 24FC04T-I/MUY supports a 1 MHz I²C bus clock frequency, with a 450 ns access time that provides adequate setup-and-hold margin at that speed."},{"question":"Is the 24FC04T-I/MUY compatible with 3.3V systems?","answer":"Yes, the 1.7V to 5.5V supply range includes 3.3V, so it is directly compatible with 3.3V logic without additional level translation."},{"question":"What is the write cycle time for the 24FC04T-I/MUY?","answer":"The write cycle time for a word or page is 5 ms, during which the EEPROM holds the I²C bus (SCL low) before the next operation can begin."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/24FC04T-I-MUY","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/24FC04T-I-MUY when reusing this data.
