4Kbit I²C EEPROM — 512 x 8 organization, 400 kHz bus
The M24C04-MN6T: With a 900 ns access time and a 5 ms write cycle (word or page), this part handles non-volatile parameter storage for configuration data, calibration constants, or small lookup tables — typical for a microcontroller's external EEPROM footprint.
STMicroelectronics lists the M24C04-MN6T as Obsolete. For new designs, consider a current-production I²C EEPROM in the same 8-SOIC footprint from the M24Cxx family — the supply voltage and pinout are consistent across the series, but verify the exact memory size and address scheme against the BOM.
The tape-and-reel packaging (Cut Tape also available) aligns with automated pick-and-place lines.
