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.
Features ■ Two-wire I2C serial interface supports 400 kHz protocol ■ Single supply voltages (see Table 1 for root part numbers): – 2.5 V to 5.5 V – 1.8 V to 5.5 V – 1.7 V to 5.5 V ■ Write Control input ■ Byte and Page Write ■ Random and Sequential Read modes ■ Self-timed programming cycle ■ Automatic address incrementing ■ Enhanced ESD/latch-up protection ■ More than 1 Million write cycles ■ More than 40-year data retention ■ Packages
