... BUS CHARACTERISTICS The following bus protocol has been defined: • Data transfer may be initiated only when the bus is not busy. • During data transfer, the data line must remain stable whenever the clock line is high. Changes in the data line, while the clock line is high, will be interpreted as a Start or Stop condition ...

... SCL SDA Data from transmitte Transmitter must release the SDA line at this point, allowing the Receiver to pull the SDA line low to acknowledge the previous eight bits of data. © 2007 Microchip Technology Inc. 24AA256/24LC256/24FC256 (D) (D) Address or Data Acknowledge Allowed Valid to Change ...

... DEVICE ADDRESSING A control byte is the first byte received following the Start condition from the master device (Figure 5-1). The control byte consists of a 4-bit control code. For the 1010’ 24XX256, this is set as ‘ binary for read and write operations. The next three bits of the control byte are the Chip Select bits (A2, A1, A0) ...

... “don’t care” bit K © 2007 Microchip Technology Inc. 24AA256/24LC256/24FC256 Upon receipt of each word, the six lower Address Pointer bits are internally incremented by one. If the master should transmit more than 64 bytes prior to generating the Stop condition, the address counter will roll over and the previously received data will be over- written ...
Page 10
... 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 ...

... SDA Line Bus Activity © 2007 Microchip Technology Inc. 24AA256/24LC256/24FC256 8.2 Random Read Random read operations allow the master to access any memory location in a random manner. To perform this type of read operation, the word address must first be set. This is done by sending the word address to the 24XX256 as part of a write operation (R/W bit set to ‘ ...
