64Kbit I²C EEPROM with wide supply range
The M24C64-RMB6TG is a 64Kbit serial EEPROM from STMicroelectronics organized as 8K x 8 bits, accessed via an I²C interface at clock frequencies up to 1 MHz. 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.
