8Kbit I2C EEPROM in a 2×3 mm package
The STMicroelectronics M24C08-FMB5TG is an 8Kbit serial EEPROM with an I²C interface, organized as 1K x 8 bits. The 400 kHz clock rate supports standard and fast-mode I²C bus speeds, while the 900 ns access time defines the read-cycle latency for the host controller. Write-cycle time is 5 ms per word or page. The part is housed in an 8-UFDFN exposed-pad package (2x3 mm), suited for space-constrained PCBs in industrial and consumer applications where non-volatile parameter storage or calibration data is needed.
The M24C08-FMB5TG is listed as obsolete by STMicroelectronics. No official successor is specified in the record.
The 8-UFDFN exposed pad (2x3 mm) requires a thermal-land pattern on the PCB; the pad is electrically connected to the substrate and should be tied to ground or left floating per the datasheet recommendation.
