2 Kbit I²C EEPROM in a 2×3 mm package
The STMicroelectronics M24C02-FMC6TG is a 2 Kbit serial EEPROM with an I²C interface, organized as 256 x 8 bits. The part comes in an 8-UFDFN exposed-pad package (2x3 mm footprint), making it a fit for space-constrained boards in mixed-voltage designs — the wide supply covers 1.8 V logic and legacy 5 V buses without external level translation.
Supply voltage range — what it buys the BOM
That saves a level-shifter IC when the rest of the board mixes voltages — the I²C SDA and SCL pins tolerate the full supply range. Write-cycle timing is 5 ms per word or page, which is standard for this density class.
400 kHz bus clock — standard-mode I²C
The 400 kHz clock frequency is the Fast-mode I²C ceiling. At 2 Kbit the access time of 900 ns is not the bottleneck — the I²C controller's bus speed and the number of stop/start conditions dictate the read/write throughput. If the system I²C bus runs slower (100 kHz standard mode), this part tracks that too; no pull-up resistor change is needed.
Package and footprint — UFDFPN-8 with exposed pad
The 8-UFDFN exposed-pad package measures 2x3 mm (supplier device package 8-UFDFPN).
No AEC-Q automotive grade is stated, so assume commercial/industrial qualification only.
