12.10.2.Description
These I
2
C -compatible electrically erasable programmable memory (EEPROM) devices are organized
as 8192 x 8 (M24C64) .These devices are compatible with the I
2
C memory protocol. This is a two wire
serial interface that uses a bi-directional data bus and serial clock. The devices carry a built-in 4-bit
Device Type Identifier code (1010) in accordance with the I
2
C bus definition.
The device behaves as a slave in the I
2
C 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, terminated by an acknowledge bit.
When writing data to the memory, the device inserts an acknowledge bit during the 9
th
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.
