It runs on a 2.5 V to 5.5 V supply and clocks up to 400 kHz. The 900 ns access time is typical for this density and bus speed — enough for configuration and calibration data storage in embedded systems. The -40°C to 85°C operating range covers industrial environments like motor drives, outdoor telecom cabinets, and factory automation panels. ## Obsolete — sourcing reality The M24C01-WMN6T is marked obsolete by STMicroelectronics. No official successor is listed in the available records. For existing BOM lines, the part is available through independent distribution — sourced and quoted to order against an RFQ. ## 900 ns access time — what it means on the bus At 400 kHz I²C, the 900 ns access time is the time from the slave address match to the first data bit being available. The 5 ms write cycle is the bigger constraint. ## Package and footprint The part comes in an 8-SOIC package (0.154-inch body width, 3.90 mm). It is a standard footprint — a board layout for a larger-density EEPROM in the same family will accept this part without a respin.","metaTitle":"STMicroelectronics M24C01-WMN6T 1Kbit I²C EEPROM, 900 ns","metaDescription":"STMicroelectronics M24C01-WMN6T 1Kbit non-volatile I²C EEPROM, 400 kHz, 2.5–5.5 V, 8-SOIC, -40°C to 85°C.
