Product overview
Description
The M24256E-U is a 256-Kbit I²C-compatible EEPROM (electrically erasable programmable memory) organized as 32 K x 8 bits. It can operate with a supply voltage from 1.7 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 an 8-bit register called the configurable device address (CDA).
The device also offers a 64-byte identification page. This additional page stores a 128‑bit (16‑byte) unique factory-programmed serial number, locked in read-only mode at factory delivery.
