Product overview
Description
The M24128-U is a 128-Kbit I²C-compatible EEPROM (electrically erasable programmable memory) organized as 16 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 (64 bytes). This page stores a 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.
