Description
These IC-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.
Logic diagram
IC 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 IC
bus definition.
The device behaves as a slave in the IC 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 device 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
terminated by a Stop condition after an Ack for Write, and after a NoAck for Read.
