M24M01E-UFMN6TP-STMicroelectronics-Price, Stock & Datasheet

The M24M01E-U is a 1-Mbit I²C-compatible EEPROM (electrically erasable programmable memory) organized as 128 K × 8 bits. It can operate with a supply voltage from 1.6 V to 5.5 V with a clock frequency up to 1 MHz, over an ambient temperature range from -40 °C to +85 °C.

The device offers three 8-bit registers, namely: the device type identifier (DTI) register, the configurable device address (CDA), and the software write protection (SWP) register.

The device also offers an additional 256-byte identification page. This page stores a 128‑bit (16‑byte) unique factory-programmed serial number, locked in read-only mode at factory delivery.

The uniqueness of the serial number is ensured across the whole portfolio of serial EEPROMs manufactured by STMicroelectronics, offering a unique identifier.
