The 1 MHz clock rate and 450 ns access time mean it keeps up with a fast I²C bus without inserting wait states on back-to-back reads. The supply range spans 1.7V to 5.5V, covering 1.8V, 2.5V, 3.3V, and 5V logic rails without a separate level translator or LDO. That simplifies the BOM when the MCU runs at 3.3V and a sensor or actuator on the same bus needs 5V — the EEPROM sits on whichever rail the bus master uses.","metaTitle":"Microchip 24FC04-E/MS I²C EEPROM, 4Kbit, 1 MHz, 125°C","metaDescription":"Microchip 24FC04-E/MS 4Kbit I²C EEPROM, 450 ns access time, 1 MHz clock, 1.7V-5.5V supply, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Package":"Tube","Technology":"EEPROM","Access Time":"450 ns","Memory Size":"4Kbit","Memory Type":"Non-Volatile","Memory Format":"EEPROM","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","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 ~ 125°C (TA)","Supplier Device Package":"8-MSOP","Write Cycle Time - Word, Page":"5ms"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.38","priceTiers":[{"qty":1,"price":"$0.38000","currency":"USD"},{"qty":25,"price":"$0.37520","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/37d8b5fcdbda24eb6e5509679260da94.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/24FC04-E%2FMS/alternatives.json"},"ai":{"faq":[{"question":"Is 24FC04-E/MS a drop-in replacement for 24LC04?","answer":"The 24FC04-E/MS is the extended-temperature variant of the 24LC04 family.
