Description
The M24M02E-F is a 2-Mbit I²C-compatible EEPROM (electrically erasable programmable memory) organized as
256 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 of -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 offers an additional 256-byte page, called the identification page. This page can be used to store
sensitive application parameters, which can later be permanently locked in read-only mode.
The M24M02E-F is available in the standard 8-pin TSSOP8, SO8N, UFDFPN8, and in the 5-ball wafer level chip
scale packaging (WLCSP) with the WC pin.
On demand, the EEPROM can be delivered with a preprogrammed and locked device address.
