Its 900 ns access time sets the minimum wait-state window the host MCU must observe between issuing a read command and clocking out the first data byte. At the 400 kHz I2C bus clock, that translates to roughly one clock cycle of dead time before the slave starts driving SDA — well within the typical MCU I2C peripheral's timing budget, but worth checking if you are bit-banging the bus in firmware. The 5 ms write-cycle time for a page or word write means the bus is busy during that interval; the host must either poll the acknowledge polling sequence or insert a 5 ms delay before the next write. For high-throughput logging, a larger page-size EEPROM or a serial Flash would be a better fit. The M24C08-WMN6 is officially obsolete per STMicroelectronics. No direct replacement has been announced in the M24C08 series. For new designs, consider the M24C08-RMN6 (same I2C 8Kbit EEPROM in 8-SOIC, with an extended temperature range) or the M24C08-FMN6 (same footprint, wider voltage range) — both are active and pin-compatible.","metaTitle":"STMicroelectronics M24C08-WMN6 I2C EEPROM, 8Kbit, 900 ns","metaDescription":"STMicroelectronics M24C08-WMN6 I2C EEPROM, 8Kbit (1K x 8), 400 kHz clock, 2.5-5.5V supply, 8-SOIC, -40°C to 85°C, 5 ms write cycle.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"title":"M24C08-WMN6","Package":"Tube","Technology":"EEPROM","Access Time":"900 ns","Memory Size":"8Kbit","Memory Type":"Non-Volatile","Memory Format":"EEPROM","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Clock Frequency":"400 kHz","lifecycle_stage":"eol_hot","Memory Interface":"I²C","Voltage - Supply":"2.5V ~ 5.5V","Base Product Number":"M24C08","Memory Organization":"1K 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":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c0cd11027252e9cf98c0fd0c0177698a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for M24C08-WMN6?","answer":"STMicroelectronics has not announced a direct replacement for the M24C08-WMN6 within the M24C08 series.
