2 Mbit serial I2C bus EEPROM

The M24M02-DR is a 2 Mbit I2C-compatible EEPROM (Electrically Erasable PROgrammable Memory) organized as 256 K × 8 bits.

The M24M02-DR can operate with a supply voltage from 1.8 V to 5.5 V, over an ambient temperature range of –40 °C / +85 °C.

The M24M02-DR offers an additional page, named the Identification Page (256 byte). The Identification Page can be used to store sensitive application parameters which can be (later) permanently locked in Read-only mode.
