STMicroelectronics M24C64-U→M24C64-UFMN6TP
64-Kbit Serial I2C bus EEPROM with a unique 128-bit read-only
The M24C64-U is a 64-Kbit I²C-compatible EEPROM (electrically erasable programmable memory) organized as 8 K × 8 bits. It can operate with a supply voltage of 1.7 V to 5.5 V, over an ambient temperature range from -40 °C to +85 °C.
The device offers an additional page, named the identification page (32 bytes). This page stores an 128‑bit (16 bytes) unique factory-programmed serial number, which is frozen in read-only mode on delivery from the factory.
The uniqueness of the serial number is ensured across the whole portfolio of serial EEPROMs manufactured by STMicroelectronics, offering a unique identifier.
