... The device that controls the data transfer is known as the bus master, and the other as the slave device. A data transfer can only be initiated by the bus master, which will also provide the serial clock for synchronization. The M24M01-R device is always a slave in all communication. ...

... M24M01-R 3.5 Memory addressing To start communication between the bus master and the slave device, the bus master must initiate a Start condition. Following this, the bus master sends the device select code, shown in Table 2 (on Serial Data (SDA), most significant bit first). The device select code consists of a 4-bit device type identifier, and a 2-bit Chip Enable “ ...

... M24M01-R 3.6 Write operations Following a Start condition the bus master sends a device select code with the R/W bit (RW) reset to 0. The device acknowledges this, as shown in bytes. The device responds to each address byte with an acknowledge bit, and then waits for the data byte. Writing to the memory may be inhibited if Write Control (WC) is driven high. Any Write ...

... ECC word), that is, the addressed byte is cycled together with the three other bytes making up the word therefore recommended to write by packets of 4 bytes in order to benefit from the larger amount of Write cycles. The M24M01-R device is qualified at 1 million (1 000 000) Write cycles, using a cycling routine that writes to the device by multiples of 4-byte words. 16/30 ...
