Description

M24128-BW M24128-BR M24128-BF M24128-DF

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.
