The wide supply range from 1.7V to 5.5V lets it operate on both 3.3V and legacy 5V buses without a level shifter. The 5 ms write cycle time (word or page) is the period after a stop condition during which the part internally programs the EEPROM cells; the bus is busy during this window, so the host must either poll the acknowledge polling sequence or insert a 5 ms delay before the next write. At 400 kHz, a page write of up to 16 bytes takes roughly 400 µs of bus time plus the 5 ms internal write, so budget about 6 ms per page update. ## Package and rework — 8-UFDFN with exposed pad The 8-UFDFN (2 mm x 3 mm) package with exposed pad is a small, low-profile option for space-constrained boards. Rework is doable with hot air — the pad is small enough that the part lifts cleanly at 300°C with a fine nozzle, but the orientation mark (pin 1 dot) is tiny, so mark the board silkscreen clearly. The 1.7V minimum supply ensures operation down to battery-end-of-life levels in portable gear.","metaTitle":"STMicroelectronics M24C04-FMC6TG EEPROM, 4Kbit I²C, 400 kHz","metaDescription":"STMicroelectronics M24C04-FMC6TG 4Kbit serial EEPROM with I²C interface, 400 kHz clock, 900 ns access, 1.7V-5.5V supply, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"STMicroelectronics","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Technology":"EEPROM","Access Time":"900 ns","Memory Size":"4Kbit","Memory Type":"Non-Volatile","Memory Format":"EEPROM","Mounting Type":"Surface Mount","Package / Case":"8-UFDFN Exposed Pad","Product Status":"Active","Clock Frequency":"400 kHz","lifecycle_stage":"eol_hot","Memory Interface":"I²C","Voltage - Supply":"1.7V ~ 5.5V","Base Product Number":"M24C04","Memory Organization":"512 x 8","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"8-UFDFPN (2x3)","Write Cycle Time - Word, Page":"5ms"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1920","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/38a813ed54df35f5b6cd248ba6b0a414.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/M24C04-FMC6TG/alternatives.json"},"ai":{"faq":[{"question":"Does M24C04-FMC6TG support 5V operation?","answer":"Yes, the supply range spans 1.7V to 5.5V, so it works directly on a 5V I²C bus without a level shifter."},{"question":"What is the write cycle time for M24C04?","answer":"The write cycle time — word or page — is 5 ms.
