M24128-B - 256/128 Kbit Serial IC Bus EEPROM

Download the M24128-B datasheet PDF. This datasheet also covers the M24256-B variant, as both devices belong to the same 256/128 kbit serial ic bus eeprom family and are provided as variant models within a single manufacturer datasheet.

General Description

These I2C-compatible electrically erasable programmable memory (EEPROM) devices are organized as 32Kx8 bits (M24256-B) and 16Kx8 bits (M24128-B).

These memory devices are compatible with the I2C extended memory standard.
