M24128-BWDW6TP Datasheet PDF - ST Microelectronics

128 Kbit, 64 Kbitand 32 Kbit serial I²C bus EEPROM

●Description

●The M24C32, M24C64 and M24128 devices are I2C-compatible electrically erasable programmable memories (EEPROM). They are organized as 4096 × 8 bits, 8192 × 8 bits and 16384 × 8 bits, respectively.

●I2C uses a two-wire serial interface, comprising a bi-directional data line and a clock line.

●The devices carry a built-in 4-bit Device Type Identifier code (1010) in accordance with the

●I2C bus definition.
