24AA04/24LC04B/24FC04 3.0 FUNCTIONAL DESCRIPTION The 24XX04 supports a bidirectional, 2-wire bus and data transmission protocol. A device that sends data onto the bus is defined as transmitter, while defining a device receiving data as a receiver. The bus has to be controlled by a master device which generates the Serial Clock (SCL), controls the bus access and generates the Start and Stop conditions, while the 24XX04 works as slave.
24AA04/24LC04B/24FC04 5.0 DEVICE ADDRESSING FIGURE 5-1: A control byte is the first byte received following the Start condition from the master device. The control byte consists of a four-bit control code. For the 24XX04, this is set as ‘1010’ binary for read and write operations. The next two bits of the control byte are “don’t cares” for the 24XX04. The last bit, B0, is used by the master device to select which of the two 256-word blocks of memory are to be accessed.
24AA04/24LC04B/24FC04 6.0 WRITE OPERATION 6.1 Byte Write 6.2 Following the Start condition from the master, the device code (4 bits), the block address (2 bits, “don’t care”, plus B0 bit) and the R/W bit, which is a logic-low, is placed onto the bus by the master transmitter. This indicates to the addressed slave receiver that a byte with a word address will follow after it has generated an Acknowledge bit during the ninth clock cycle.

24AA04/24LC04B/24FC04 7.0 ACKNOWLEDGE POLLING Since the device will not acknowledge during a write cycle, this can be used to determine when the cycle is complete (this feature can be used to maximize bus throughput). Once the Stop condition for a write command has been issued from the master, the device initiates the internally-timed write cycle. ACK polling can then be initiated immediately. This involves the master sending a Start condition followed by the control byte for a write command (R/W = 0).
24AA04/24LC04B/24FC04 8.0 READ OPERATION 8.3 Sequential Read Read operations are initiated in the same way as write operations, with the exception that the R/W bit of the slave address is set to ‘1’. There are three basic types of read operations: current address read, random read and sequential read.
