Description
These I²C-compatible electrically erasable programmable memory (EEPROM) devices are
organized as 2048/1024/512/256/128 x 8 (M24C16, M24C08, M24C04, M24C02 and
M24C01).
Figure 1.
I²C uses a two-wire serial interface, comprising a bidirectional 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. The Start condition is followed by a device select code and Read/Write
bit (RW) (as described in
When writing data to the memory, the device inserts an acknowledge bit during the 9
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 after a NoAck for Read.
