These electrically erasable programmable memory (EEPROM) devices are accessed through a Serial Data Input (D) and Serial Data Output (Q) using the MICROWIRE bus protocol. In order to meet environmental requirements, ST offers these devices in ECOPACK® packages. ECOPACK packages are Lead-free and RoHS compliant.

These I2C-compatible electrically erasable programmable memory (EEPROM) devices are organized as 8192 x 8 bits (M24C64) and 4096 x 8 bits (M24C32). 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. The device behaves as a slave in the I2C protocol, with all memory operations synchronized by the serial clock. Read and Write operations are initiated by a Start condition, generated by the bus master.
