Description
The M24128 is a 128-Kbit I2C-compatible EEPROM (Electrically Erasable PROgrammable Memory) organized as 16 K × 8 bits.
The M24128-BW can operate with a supply voltage from 2.5 V to 5.5 V, the M24128-BR can operate with a supply voltage from 1.8 V to 5.5 V, and the M24128-BF and M24128-DF can operate with a supply voltage from 1.7 V to 5.5 V. All these devices operate with a clock frequency of 1 MHz (or less), over an ambient temperature range of –40 °C / +85 °C. The M24128-D offers an additional page, named the Identification Page (64 byte). The Identification Page can be used to store sensitive application parameters which can be (later) permanently locked in Read-only mode.
