M24C01

These I²C-compatible electrically erasable programmable memory (EEPROM) devices M24C01 are organized as 2048/1024/512/256/128 x 8 (M24C16, M24C08, M24C04, M24C02 and M24C01).

In order to meet environmental requirements, ST offers these devices in ECOPACK® packages.

ECOPACK® packages M24C01 are Lead-free and RoHS compliant.

ECOPACK M24C01 is an ST trademark. ECOPACK specifications are available at: www.st.com.

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 M24C01 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. The Start condition is followed by a Device Select Code and Read/Write bit (RW) (as described in Table 3), terminated by an acknowledge bit.

When writing data to the memory, the M24C01 inserts an acknowledge bit during the 9th bit time, following the bus master's 8-bit transmission. When data is read by the bus master, the bus master acknowledges the receipt of the data byte in the same way. Data transfers are erminated by a Stop condition after an Ack for Write, and after a NoAck for Read.
