2 / 17 page M24256, M24128 2/17 serial interface that uses a bi-directional data bus and serial clock. The memory carries a built-in 4- bit unique Device Type Identifier code (1010) in accordance with the I2C bus definition. The memory behaves as a slave device 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 RW bit (as described in Table 3), terminated by an acknowledge bit. When writing data to the memory, the memory in- serts 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 terminated by a STOP condition after an Ack for WRITE, and af- ter a NoAck for READ. Power On Reset: VCC Lock-Out Write Protect In order to prevent data corruption and inadvertent write operations during power up, a Power On Re- set (POR) circuit is included. The internal reset is held active until the VCC voltage has reached the POR threshold value, and all operations are dis- abled – the device will not respond to any com- mand. In the same way, when VCC drops from the operating voltage, below the POR threshold value, all operations are disabled and the device will not respond to any command. A stable and valid VCC must be applied before applying any logic signal. SIGNAL DESCRIPTION Serial Clock (SCL) The SCL input pin is used to strobe all data in and out of the memory. In applications where this line is used by slaves to synchronize the bus to a slow- Figure 2A. DIP Connections Note: 1.

Except for the rating “Operating Temperature Range”, stresses above those listed in the Table “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and operation of the device at these or any other conditions above those indicated in the Operating sections of this specification is not implied. Exposure to Absolute Maximum Rating condi- tions for extended periods may affect device reliability. Refer also to the ST SURE Program and other relevant quality documents. 2. IPC/JEDEC J-STD-020A 3.
