The 900 ns access time and 400 kHz clock rate suit typical microcontroller I2C peripherals for parameter storage, calibration data, and device configuration in outdoor telecom, factory automation, and engine-bay applications. That means STMicroelectronics is not actively promoting it for new projects, and the production window is finite. For existing BOM lines, secure your last-time-buy quantities or qualify a pin-compatible successor. The base product number M24C04 family includes multiple variants; verify the exact replacement with ST's current product selector or your distributor's cross-reference tool. ## Supply range and I2C bus compatibility The 2.5V to 5.5V supply means this EEPROM works directly on 3.3V and 5V buses without a level shifter, as long as the I2C pull-up resistors are sized for the rail voltage. The 400 kHz clock is standard fast-mode I2C; most MCU I2C peripherals support it natively. Housed in an 8-TSSOP (4.40 mm width) package, surface-mount.","metaTitle":"STMicroelectronics M24C04-WDW6TP EEPROM, 4Kbit I2C, 900 ns","metaDescription":"STMicroelectronics M24C04-WDW6TP 4Kbit I2C EEPROM in 8-TSSOP. 900 ns access, 400 kHz clock, 2.5V-5.5V supply, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","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-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Not For New Designs","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-TSSOP","Write Cycle Time - Word, Page":"5ms"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/38a813ed54df35f5b6cd248ba6b0a414.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/M24C04-WDW6TP/alternatives.json"},"ai":{"faq":[{"question":"Is M24C04-WDW6TP obsolete or NRND?","answer":"It is not yet fully discontinued, but STMicroelectronics is phasing it out. Plan a last-time-buy or qualify a replacement now."},{"question":"Does M24C04-WDW6TP work with 5V logic?","answer":"Yes. The supply voltage range is 2.5V to 5.5V, so it operates directly on a 5V rail. The I2C interface is 5V-tolerant at the bus pins when pull-ups are referenced to 5V."},{"question":"Can I use M24C04-WDW6TP with 3.3V?","answer":"Yes. The 2.5V minimum supply covers 3.3V operation. The I2C bus runs at 400 kHz with 3.3V pull-ups; the device is specified across the full 2.5V-5.5V range."},{"question":"What is the difference between M24C04-WDW6TP and M24C04-WDW6T?","answer":"The difference is in the packaging and shipping medium: the 'P' suffix typically indicates Tape & Reel packaging, while the non-P variant may ship in a different format. The silicon and electrical specs (4Kbit, I2C, 400 kHz, 2.5V-5.5V, -40°C to 85°C) are identical.
