24AA02E48/24AA025E48/24AA02E64/24AA025E64 3.0 FUNCTIONAL DESCRIPTION The 24AA02XEXX supports a bidirectional, 2-wire bus and data transmission protocol. A device that sends data onto the bus is defined as transmitter, while a device receiving data is defined 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 24AA02XEXX works as slave.
PAGE 8
24AA02E48/24AA025E48/24AA02E64/24AA025E64 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 24AA02XEXX, this is set as ‘1010’ binary for read and write operations. For the 24AA02E48/24AA02E64 the next three bits of the control byte are “don’t cares”. For the 24AA025E48/24AA025E64, the next three bits of the control byte are the Chip Select bits (A2, A1, A0).
PAGE 9
24AA02E48/24AA025E48/24AA02E64/24AA025E64 6.0 WRITE OPERATION 6.1 Byte Write 24AA025E64) of the word address remain constant. If the master should transmit more than eight words (16 for the 24AA025E48/24AA025E64) prior to generating the Stop condition, the address counter will roll over and the previously received data will be overwritten. As with the byte write operation, once the Stop condition is received an internal write cycle will begin (Figure 6-2).
PAGE 10
24AA02E48/24AA025E48/24AA02E64/24AA025E64 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 and ACK polling can then be initiated immediately.
PAGE 11
24AA02E48/24AA025E48/24AA02E64/24AA025E64 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.

The remaining 1,024 bits are available for application use. FIGURE 9-1: MEMORY ORGANIZATION 00h 9.1.

24AA02E48/24AA025E48/24AA02E64/24AA025E64 9.2 EUI-64™ Node Address (24AAXXXE64) The remaining five bytes are the Extension Identifier, and are generated by Microchip to ensure a globally unique, 64-bit value. The 8-byte EUI-64™ node address value of the 24AAXXXE64 is stored in array locations 0xF8 through 0xFF, as shown in Figure 9-3. The first three bytes are the Organizationally Unique Identifier (OUI) assigned to Microchip by the IEEE Registration Authority.
