4Kbit I²C EEPROM in a 2×3 mm package
The M24C04-RMB6TG is a 4Kbit serial EEPROM from STMicroelectronics, organized as 512 x 8 bits and accessed via an I²C interface at up to 400 kHz. Its 1.8V to 5.5V supply range lets it sit on a 3.3V or 5V rail without a level translator, and the 900 ns access time is adequate for parameter storage and calibration data reads in embedded systems.
STMicroelectronics lists the M24C04-RMB6TG as Obsolete.
Housed in an 8-UFDFN exposed-pad package (2×3 mm body), the part is surface-mount and supplied on Tape & Reel.
Write-cycle timing and memory endurance
The write cycle time for a word or page is 5 ms. This is typical for I²C EEPROMs of this density; the host firmware must wait or poll the acknowledge polling sequence before issuing the next write. The non-volatile storage retains data across power cycles, making it suitable for configuration parameters, calibration constants, and device serialization.
