24AA01/24LC01B/24FC01 5.0 DEVICE ADDRESSING FIGURE 5-1: CONTROL BYTE ALLOCATION A control byte is the first byte received following the Start condition from the master device. The control byte Read/Write Bit consists of a four-bit control code. For the 24XX01, this is set as ‘1010’ binary for read and write operations. Block The next three bits of the control byte are “don’t cares” Select Control Code Bits for the 24XX01. The combination of the 4-bit control code and the next three bits are called the slave address. S 1 0 1 0 x x x R/W ACK The last bit of the control byte is the Read/Write (R/W) bit and it defines the operation to be performed. When Slave Address set to ‘1’, a read operation is selected. When set to ‘0’, a write operation is selected. Following the Start condition, the 24XX01 monitors the SDA bus, checking Start Bit Acknowledge Bit the device type identifier being transmitted. Upon receiving a valid slave address and the R/W bit, the x = “don’t care” slave device outputs an Acknowledge signal on the SDA line. Depending on the state of the R/W bit, the 24XX01 will select a read or write operation. The next byte received defines the address of the first data byte within the selected block (Figure5-2). Because only A6…A0 are used, the upper address bit is a “don’t care”.

24AA01/24LC01B/24FC01 6.0 WRITE OPERATION 6.2 Page Write The write control byte, word address and first data byte 6.1 Byte Write are transmitted to the 24XX01 in the same way as in a byte write. However, instead of generating a Stop Following the Start condition from the master, the condition, the master transmits up to 8 data bytes to the device code (4 bits), the block address (3 bits, “don’t 24XX01, which are temporarily stored in the on-chip cares”) and the R/W bit, which is a logic-low, is placed page buffer and will be written into the memory once onto the bus by the master transmitter. This indicates to the master has transmitted a Stop condition. Upon the addressed slave receiver that a byte with a word receipt of each word, the three lower-order Address address will follow after it has generated an Pointer bits, which form the byte counter, are internally Acknowledge bit during the ninth clock cycle. incremented by one. The higher-order five bits of the Therefore, the next byte transmitted by the master is word address remain constant. If the master should the word address and will be written into the Address transmit more than eight words prior to generating the Pointer of the 24XX01. After receiving another Stop condition, the Address Pointer will roll over and Acknowledge signal from the 24XX01, the master the previously received data will be overwritten. As with device will transmit the data word to be written into the the byte write operation, once the Stop condition is addressed memory location. The 24XX01 received, an internal write cycle will begin (Figure6-2). acknowledges again and the master generates a Stop condition. This initiates the internal write cycle, and, during this time, the 24XX01 will not generate Note: Page write operations are limited to writ- Acknowledge signals (Figure6-1). ing bytes within a single physical page regardless of the number of bytes actually being written. Physical page boundaries start at addresses that are integer multiples of the page buffer size (or ‘page size’) and end at addresses that are integer multiples of page size – 1. If a page write command attempts to write across a physical page boundary, the result is that the data wraps around to the beginning of the current page (overwriting data previously stored there), instead of being written to the next page, as might be expected. It is therefore necessary for the application software to prevent page write operations that would attempt to cross a page boundary. 6.3 Write Protection The WP pin allows the user to write-protect the entire array (00-7F) when the pin is tied to VCC. If tied to VSS, the write protection is disabled.

24AA01/24LC01B/24FC01 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). If the device is still busy with the write cycle, no ACK will be returned. If the cycle is complete, the device will return the ACK and the master can then proceed with the next read or write operation. See Figure7-1 for a flow diagram of this operation. FIGURE 7-1: ACKNOWLEDGE POLLING FLOW Send Write Command Send Stop Condition to Initiate Write Cycle Send Start Send Control Byte with R/W = 0 Did Device No Acknowledge (ACK = 0)?

24AA01/24LC01B/24FC01 8.0 READ OPERATION 8.3 Sequential Read Read operations are initiated in the same way as write Sequential reads are initiated in the same way as a operations, with the exception that the R/W bit of the random read, except that once the 24XX01 transmits slave address is set to ‘1’. There are three basic types the first data byte, the master issues an acknowledge of read operations: current address read, random read (as opposed to a Stop condition in a random read). This and sequential read. directs the 24XX01 to transmit the next sequentially addressed 8-bit word (Figure8-3). 8.1 Current Address Read To provide sequential reads the 24XX01 contains an internal Address Pointer which is incremented by one The 24XX01 contains an Address Pointer that at the completion of each operation. This Address maintains the address of the last word accessed, Pointer allows the entire memory contents to be serially internally incremented by one. Therefore, if the previ- read during one operation. ous access (either a read or write operation) was to address n, the next current address read operation 8.4 Noise Protection would access data from address n + 1. Upon receipt of the slave address with R/W bit set to ‘1’, the 24XX01 The SCL and SDA inputs have Schmitt Trigger and issues an acknowledge and transmits the 8-bit data filter circuits which suppress noise spikes to assure word. The master will not acknowledge the transfer, but proper device operation even on a noisy bus. does generate a Stop condition and the 24XX01 discontinues transmission (Figure8-1). 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 accomplished by sending the word address to the 24XX01 as part of a write operation. Once the word address is sent, the master generates a Start condition following the acknowledge. This terminates the write operation, but not before the inter- nal Address Pointer is set. The master then issues the control byte again, but with the R/W bit set to a ‘1’. The 24XX01 will then issue an acknowledge and transmits the 8-bit data word. The master will not acknowledge the transfer, but does generate a Stop condition and the 24XX01 discontinues transmission (Figure8-2).

24AA01/24LC01B/24FC01 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. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act.
