For normal data transfer, SDA is allowed to change only during SCL low. Changes during SCL high are reserved for indicating the Start and Stop conditions. 2010 Microchip Technology Inc.

24AA128/24LC128/24FC128 5.0 DEVICE ADDRESSING FIGURE 5-1: CONTROL BYTE FORMAT A control byte is the first byte received following the Start condition from the master device (Figure5-1). Read/Write Bit The control byte consists of a 4-bit control code. For the 24XX128, this is set as ‘1010’ binary for read and write Chip Select operations. The next three bits of the control byte are Control Code Bits the Chip Select bits (A2, A1, A0). The Chip Select bits allow the use of up to eight 24XX128 devices on the S 1 0 1 0 A2 A1 A0 R/W ACK same bus and are used to select which device is accessed. The Chip Select bits in the control byte must Slave Address correspond to the logic levels on the corresponding A2, A1 and A0 pins for the device to respond.

During device addressing, the A0 and A1 Multiple Devices Chip Select bits (Figures5-1 and 5-2) should be set to The Chip Select bits A2, A1 and A0 can be used to ‘0’.

In this case, software can use A0 of the control be performed. When set to a one, a read operation is byte as address bit A14; A1 as address bit A15; and A2 selected. When set to a zero, a write operation is as address bit A16. It is not possible to sequentially selected. The next two bytes received define the read across device boundaries. address of the first data byte (Figure5-2).

Upon receiving a ‘1010’ code and appropriate device select bits, the slave device outputs an Acknowledge signal on the SDA line. Depending on the state of the R/W bit, the 24XX128 will select a read or write operation.

If tied to Following the Start condition from the master, the VSS the write protection is disabled.

Toggling the WP pin after the Stop bit will bus by the master transmitter. This indicates to the have no effect on the execution of the write cycle. addressed slave receiver that the address high byte will follow after it has generated an Acknowledge bit during Note: Page write operations are limited to the ninth clock cycle.

After receiving another that are integer multiples of the page Acknowledge signal from the 24XX128, the master buffer size (or ‘page size’) and end at device will transmit the data word to be written into the addresses that are integer multiples of addressed memory location. The 24XX128 acknowl- [page size – 1]. If a Page Write edges again and the master generates a Stop command attempts to write across a condition. This initiates the internal write cycle and physical page boundary, the result is during this time, the 24XX128 will not generate that the data wraps around to the Acknowledge signals (Figure6-1). If an attempt is beginning of the current page (over- made to write to the array with the WP pin held high, the writing data previously stored there), device will acknowledge the command, but no write instead of being written to the next cycle will occur, no data will be written, and the device page, as might be expected. It is, will immediately accept a new command. After a byte therefore, necessary for the applica- Write command, the internal address counter will point tion software to prevent page write to the address location following the one that was just operations that would attempt to cross written. a page boundary. Note: When doing a write of less than 64 bytes the data in the rest of the page is refreshed along with the data bytes being written. This will force the entire page to endure a write cycle, for this reason endurance is specified per page. 6.2 Page Write The write control byte, word address, and the first data byte are transmitted to the 24XX128 in much the same way as in a byte write. The exception is that instead of generating a Stop condition, the master transmits up to 63 additional bytes, which are temporarily stored in the on-chip page buffer, and will be written into memory once the master has transmitted a Stop condition. Upon receipt of each word, the six lower Address Pointer bits are internally incremented by ‘1’. 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. As with the byte write operation, once the Stop condition is received, an internal write cycle will begin (Figure6-2). If an attempt is made to write to the array with the WP pin held high, the device will acknowledge the command, but no write cycle will occur, no data will be written and the device will immediately accept a new command.

Once the Stop condition for a Write Send command has been issued from the master, the device Write Command initiates the internally timed write cycle. ACK polling can be initiated immediately. This involves the master sending a Start condition, followed by the control byte Send Stop for a Write command (R/W = 0). If the device is still Condition to busy with the write cycle, then no ACK will be returned. Initiate Write Cycle If no ACK is returned, the Start bit and control byte must be resent.

To perform the control byte is set to ‘1’. There are three basic types this type of read operation, the word address must first of read operations: current address read, random read be set. This is done by sending the word address to the and sequential read. 24XX128 as part of a write operation (R/W bit set to ‘0’).

After a random Read command, the the 24XX128 issues an acknowledge and transmits the internal address counter will point to the address 8-bit data word. The master will not acknowledge the location following the one that was just read. transfer, but does generate a Stop condition and the 24XX128 discontinues transmission (Figure8-1). 8.3 Sequential Read Sequential reads are initiated in the same way as a FIGURE 8-1: CURRENT ADDRESS random read except that after the 24XX128 transmits READ the first data byte, the master issues an acknowledge S as opposed to the Stop condition used in a random T S Bus Activity A Control Data T read. This acknowledge directs the 24XX128 to Master R Byte Byte O transmit the next sequentially addressed 8-bit word T P (Figure8-3). Following the final byte transmitted to the SDA Line AAA S 1 0 1 0 2 1 0 1 P master, the master will NOT generate an acknowledge A N but will generate a Stop condition. To provide Bus Activity C O sequential reads, the 24XX128 contains an internal K A Address Pointer which is incremented by one at the C K completion of each operation. This Address Pointer allows the entire memory contents to be serially read during one operation. The internal Address Pointer will automatically roll over from address 3FFF to address 0000 if the master acknowledges the byte received from the array address 3FFF.

Note the following details of the code protection feature on Microchip devices: • Microchip products meet the specification contained in their particular Microchip Data Sheet. • Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. • There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. • Microchip is willing to work with the customer who is concerned about the integrity of their code. • Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.” Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products.
