... The FM24C08U/09U devices are 8192 bits of CMOS non-volatile electrically erasable memory. These devices conform to all speci- fications in the Standard IIC 2-wire protocol. They are designed to minimize device pin count and simplify PC board layout require- ments. The upper half (upper 4Kbit) of the memory of the FM24C09U can ...

... NC No Connection Pins designated as "NC" are typically unbonded pins. However some of them are bonded for special testing purposes. Hence if a signal is applied to these pins, care should be taken that the voltage applied on these pins does not exceed the V FM24C08U/09U Rev. A ...

... During the write cycle, the WR FM24C08U/09U bus interface circuits are disabled, SDA is allowed to remain high per the bus-level pull-up resistor, and the device does not respond to its slave address. Refer "Write Cycle Timing" diagram. ...

... Last bit of the Slave Address indicates if the intended access is Read or Write. If the bit is "1," then the access is Read, whereas if the bit is "0," then the access is Write. FM24C08U/09U Rev. A.3 Acknowledge is an active LOW pulse on the SDA line driven by an addressed receiver to the addressing transmitter to indicate receipt of 8-bits of data ...

... All communications are terminated by a stop condition, which is a LOW to HIGH transition of SDA when SCL is HIGH. The stop condition is also used by the FM24C08U/09U to place the device in the standby power mode, except when a Write operation is being executed, in which case a second stop condition is required ...

... FM24C08U/09U will respond with an acknowledge after the receipt of each subsequent eight bit byte. In the read mode the FM24C08U/09U slave will transmit eight bits of data, release the SDA line and monitor the line for an acknowl- edge acknowledge is detected, FM24C08U/09U will continue to transmit data ...

... The master then terminates the transfer by generating a stop condition at which time the FM24C08U/ 09U begins the internal write cycle to the nonvolatile memory. While the internal write cycle is in progress, the FM24C08U/09U inputs ...

... R/W bit set to one. This will be followed by an acknowl- edge from the FM24C08U/09U and then by the eight bit word. The master will not acknowledge the transfer but does generate the stop condition, and therefore the FM24C08U/09U discontinues transmission ...
