描述 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.
