The part supports a 400 kHz clock frequency and delivers a 900 ns access time, which is typical for fast-mode I²C EEPROMs. Write operations complete in 5 ms per word or page. The memory is non-volatile, retaining data without power. ## NRND — plan a replacement for new designs While existing production can continue using stocked inventory or last-time-buy quantities, any new BOM should target a pin-compatible replacement within the M24C02 family or a similar I²C EEPROM from ST or another vendor. ## What the 900 ns access time and 5 ms write cycle mean for your bus The 900 ns access time is the delay from the I²C address byte to the first data byte appearing on the bus. At 400 kHz, the SCL period is 2.5 µs, so the access time adds less than one clock cycle of wait — the MCU can poll the part without stalling the bus. The 5 ms write cycle is the time the EEPROM needs to program the internal array after a write command; during this window the part does not acknowledge its address, so the host must retry or wait. For small configuration blocks (a few bytes), this is transparent. For streaming writes, budget the 5 ms per page.","metaTitle":"STMicroelectronics M24C02-WMN6P 2Kbit I²C EEPROM, 400 kHz","metaDescription":"STMicroelectronics M24C02-WMN6P 2Kbit I²C EEPROM, 256x8, 400 kHz clock, 2.5V-5.5V supply, 900 ns access, -40°C to 85°C, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"STMicroelectronics","Series":"-","Package":"Tube","Technology":"EEPROM","Access Time":"900 ns","Memory Size":"2Kbit","Memory Type":"Non-Volatile","Memory Format":"EEPROM","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm 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":"M24C02","Memory Organization":"256 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":"$0.1800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0ebd86c753cbd45e05f6fa564548737f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/M24C02-WMN6P/alternatives.json"},"ai":{"faq":[{"question":"Is M24C02-WMN6P RoHS compliant?","answer":"The evidence does not explicitly state RoHS compliance, but STMicroelectronics typically marks RoHS-compliant parts with a suffix.
