The STMicroelectronics M24C16-WMN6T is a 16Kbit serial EEPROM with an I²C interface, organized as 2K x 8 bits. It operates from a 2.5V to 5.5V supply, clocks up to 400 kHz, and delivers a 900 ns access time. The non-volatile memory retains data through power loss, making it a standard choice for parameter storage, calibration constants, and configuration data in embedded systems.
The M24C16-WMN6T is marked Obsolete by STMicroelectronics. No official successor is listed in the available records. For a BOM that requires this exact order code, the only channel is the independent surplus and broker market.
900 ns access time — bus timing margin
The 900 ns access time is the time from the last I²C clock edge to valid data on the SDA line. At 400 kHz, the access time fits within the I²C specification's data-valid window.
