... This is explained in more detail in the interface section below. Users can expect several obvious system benefits from the FM24C04C due to its fast write cycle and high endurance as compared with EEPROM. However there are less obvious benefits as well. For example in a high noise environment, the fast-write operation is less susceptible to corruption than an EEPROM since it is completed quickly ...

... When a read operation is complete and no more data is needed, the receiver must not acknowledge acknowledges the last byte, this will cause the FM24C04C to attempt to drive the bus on the next clock while the master is sending a new command such as a Stop command. Slave Address The first byte that the FM24C04C expects after a start condition is the slave address ...

... After all address information has been transmitted, data transfer between the bus master and the FM24C04C can begin. For a read operation the FM24C04C will place 8 data bits on the bus then wait for an acknowledge. If the acknowledge occurs, the next sequential byte will be transferred. If the acknowledge is not sent, the read operation is concluded ...

... FM24C04C should read out the next sequential byte. There are four ways to properly terminate a read operation. Failing to properly terminate the read will most likely create a bus contention as the FM24C04C Rev. 1.1 June 2011 Address & Data 0 A Word Address Acknowledge Figure 5 ...

... Therefore, endurance cycles are applied for each read or write cycle. The memory architecture is based on an array of rows and columns. Each read or write access causes an endurance cycle for an entire row. In the FM24C04C, a row is 64 bits wide. Every 8-byte boundary marks Rev. 1.1 June 2011 ...
