M24128-B 256/128 Kbit Serial IC Bus EEPROM

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. This is a two wire serial interface that uses a bi-directional data bus and ser.
