Its supply voltage spans 1.8V to 5.5V, covering both 3.3V and 5V logic rails without a level translator, and the 450 ns access time keeps the I²C bus timing budget manageable even with multiple slaves. ## Obsolete — plan for last-time buy or substitute STMicroelectronics lists the M24C64-RMB6TG as Obsolete, meaning no further production runs are scheduled. ## Package and thermal land planning The write cycle time of 5 ms per word or page sets the minimum polling interval for the host controller; a 1 MHz I²C clock allows a full page write to complete in under 10 ms including the address and data bytes.","metaTitle":"M24C64-RMB6TG 64Kbit I²C EEPROM – Obsolete","metaDescription":"STMicroelectronics M24C64-RMB6TG 64Kbit I²C EEPROM, 1 MHz, 450 ns, 1.8V-5.5V, -40°C to 85°C, 8-UFDFN.
