The 900 ns access time and 5 ms write cycle (word or page) suit configuration storage, calibration data, and small parameter logs in industrial and consumer equipment. ## Obsolete — plan for replacement or surplus sourcing ## Supply voltage range and logic compatibility Rated for 2.5V to 5.5V supply, this EEPROM works directly with 3.3V and 5V microcontrollers and ASICs. The I²C interface is open-drain, so pull-up resistors should be sized for the bus capacitance and supply voltage — 4.7 kΩ is typical for a 400 kHz bus at 5V. No level shifter is needed when mixing 3.3V and 5V domains on the same I²C bus, as long as the pull-up voltage matches the higher supply.","metaTitle":"STMicroelectronics M24C04-WMN6T EEPROM, 4Kbit I²C, 400 kHz","metaDescription":"STMicroelectronics M24C04-WMN6T 4Kbit serial EEPROM, I²C interface, 400 kHz clock, 2.5V-5.5V supply, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Obsolete","Clock Frequency":"400 kHz","lifecycle_stage":"eol_hot","Memory Interface":"I²C","Voltage - Supply":"2.5V ~ 5.5V","Base Product Number":"M24C04","Memory Organization":"512 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":"$27.4600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/38a813ed54df35f5b6cd248ba6b0a414.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/M24C04-WMN6T/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for M24C04-WMN6T?","answer":"A common pin-compatible replacement is the M24C04-WMN6TP, which shares the same 8-SOIC package and I²C interface.
