The device supports a 1 MHz clock rate and delivers a 450 ns access time, which is standard for this class of serial EEPROM and sufficient for most non-volatile parameter storage, calibration data, and small lookup-table applications. ## Supply voltage flexibility and I2C bus compatibility The 1 MHz clock frequency matches the I2C fast-mode plus specification, so the part will interoperate with most modern MCU I2C peripherals at their maximum bit rate. ## Write-cycle timing and endurance considerations The write cycle time is 5 ms for a word or page write. In a production firmware-update scenario where the EEPROM stores configuration parameters updated every few seconds, that 5 ms write window is negligible. For applications that write frequently—say, every 100 ms—the write time accumulates and may need to be factored into the system timing budget.","metaTitle":"STMicroelectronics M24C64-DFMN6TP 64Kbit I2C EEPROM, 1 MHz","metaDescription":"STMicroelectronics M24C64-DFMN6TP 64Kbit serial I2C EEPROM in SOIC-8, 1.7V-5.5V supply, 1 MHz clock, 450 ns access.
