2Kbit I2C EEPROM in 8-TSSOP — what this part is
The STMicroelectronics M24C02-FDW6TP is a 2Kbit serial EEPROM with an I2C interface, organized as 256 x 8 bits. It is a standard non-volatile memory for storing configuration parameters, calibration data, device IDs, or small firmware patches in embedded systems.
The 1.7V minimum supply means it works directly on a 1.8V microcontroller rail without a regulator — useful for battery-powered or low-power edge nodes.
I2C bus and write cycle
The I2C interface runs at 400 kHz (Fast Mode). Access time is 900 ns, which is well within the I2C timing budget at that speed. Page write operations are supported; the write cycle time per page is 5 ms. For a 2Kbit device organized as 256 bytes, a full chip write in page mode takes roughly 40 ms (8 pages × 5 ms).
