2.1
A0, A1, A2 Chip Address Inputs
2.3
Serial Clock (SCL)
The A0, A1 and A2 inputs are used by the 24XX128 for multiple device operations. The levels on these inputs are compared with the corresponding bits in the slave address. The chip is selected if the compare is true. For the MSOP package only, pins A0 and A1 are not connected. Up to eight devices (two for the MSOP package) may be connected to the same bus by using different Chip Select bit combinations. If these pins are left unconnected, the inputs will be pulled down internally to VSS. If they are tied to VCC or driven high, the internal pull-down circuitry is disabled. In most applications, the chip address inputs A0, A1, and A2 are hard-wired to logic `0' or logic `1'. For applications in which these pins are controlled by a microcontroller or other programmable device, the chip address pins must be driven to logic `0' or logic `1' before normal device operation can proceed.
This input is used to synchronize the data transfer to and from the device.
2.4
Write-Protect (WP)
This pin can be connected to either VSS, VCC or left floating. Internal pull-down circuitry on this pin will keep the device in the unprotected state if left floating. If tied to VSS or left floating, normal memory operation is enabled (read/write the entire memory 0000-3FFF). If tied to VCC, write operations are inhibited. Read operations are not affected.
3.0
FUNCTIONAL DESCRIPTION
2.2
Serial Data (SDA)
This is a bidirectional pin used to transfer addresses and data into and out of the device. It is an open drain terminal. Therefore, the SDA bus requires a pull-up resistor to VCC (typical 10 k for 100 kHz, 2 k for 400 kHz and 1 MHz). 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.
The 24XX128 supports a bidirectional 2-wire bus and data transmission protocol. A device that sends data onto the bus is defined as a transmitter and a device receiving data as a receiver. The bus must 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 24XX128 works as a slave. Both master and slave can operate as a transmitter or receiver, but the master device determines which mode is activated.

4.0 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. Accordingly, the following bus conditions have been defined (Figure 4-1). The data on the line must be changed during the low period of the clock signal. There is one bit of data per clock pulse. Each data transfer is initiated with a Start condition and terminated with a Stop condition. The number of the data bytes transferred between the Start and Stop conditions is determined by the master device.
4.5
Acknowledge
4.1 4.2
Bus not Busy (A) Start Data Transfer (B)
Both data and clock lines remain high.
Each receiving device, when addressed, is obliged to generate an Acknowledge signal after the reception of each byte. The master device must generate an extra clock pulse, which is associated with this Acknowledge bit. Note: The 24XX128 does not generate any Acknowledge bits if an internal programming cycle is in progress.
A high-to-low transition of the SDA line while the clock (SCL) is high determines a Start condition. All commands must be preceded by a Start condition.
4.3
Stop Data Transfer (C)
A low-to-high transition of the SDA line, while the clock (SCL) is high, determines a Stop condition. All operations must end with a Stop condition.
4.4
Data Valid (D)
The state of the data line represents valid data when, after a Start condition, the data line is stable for the duration of the high period of the clock signal.
A device that acknowledges must pull down the SDA line during the acknowledge clock pulse in such a way that the SDA line is stable low during the high period of the acknowledge related clock pulse. Of course, setup and hold times must be taken into account. During reads, a master must signal an end of data to the slave by NOT generating an Acknowledge bit on the last byte that has been clocked out of the slave. In this case, the slave (24XX128) will leave the data line high to enable the master to generate the Stop condition.

5.0 DEVICE ADDRESSING
FIGURE 5-1:
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 24XX128, this is set as `1010' binary for read and write operations. The next three bits of the control byte are the Chip Select bits (A2, A1, A0). The Chip Select bits allow the use of up to eight 24XX128 devices on the same bus and are used to select which device is accessed. The Chip Select bits in the control byte must correspond to the logic levels on the corresponding A2, A1 and A0 pins for the device to respond. These bits are, in effect, the three Most Significant bits of the word address. For the MSOP package, the A0 and A1 pins are not connected. During device addressing, the A0 and A1 Chip Select bits (Figures 5-1 and 5-2) should be set to `0'. Only two 24XX128 MSOP packages can be connected to the same bus. The last bit of the control byte defines the operation to be performed. When set to a one, a read operation is selected. When set to a zero, a write operation is selected. The next two bytes received define the address of the first data byte (Figure 5-2). Because only A13...A0 are used, the upper two address bits are "don't care" bits. The upper address bits are transferred first, followed by the less significant bits. Following the Start condition, the 24XX128 monitors the SDA bus checking the device type identifier being transmitted. 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.

Contiguous Addressing Across Multiple Devices
The Chip Select bits A2, A1,and A0 can be used to expand the contiguous address space for up to 1 Mbit by adding up to eight 24XX128s on the same bus. In this case, software can use A0 of the control byte as address bit A14; A1 as address bit A15; and A2 as address bit A16. It is not possible to sequentially read across device boundaries. For the MSOP package, up to two 24XX128 devices can be added for up to 256 Kbit of address space. In this case, software can use A2 of the control byte as address bit A16. Bits A0 (A14) and A1 (A15) of the control byte must always be set to logic `0' for the MSOP.

6.1
WRITE OPERATIONS
Byte Write
Following the Start condition from the master, the control code (four bits), the Chip Select (three bits) and the R/W bit (which is a logic low) are clocked onto the bus by the master transmitter. This indicates to the addressed slave receiver that the address high byte will follow after it has generated an Acknowledge bit during the ninth clock cycle. Therefore, the next byte transmitted by the master is the high-order byte of the word address and will be written into the address pointer of the 24XX128. The next byte is the Least Significant Address Byte. After receiving another Acknowledge signal from the 24XX128, the master device will transmit the data word to be written into the addressed memory location. The 24XX128 acknowledges again and the master generates a Stop condition. This initiates the internal write cycle and during this time, the 24XX128 will not generate Acknowledge signals (Figure 6-1). 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. After a byte Write command, the internal address counter will point to the address location following the one that was just written.
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 overwritten. As with the byte write operation, once the Stop condition is received, an internal write cycle will begin (Figure 6-2). 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.
6.3
Write-Protection
The WP pin allows the user to write-protect the entire array (0000-3FFF) when the pin is tied to VCC. If tied to VSS or left floating, the write protection is disabled. The WP pin is sampled at the Stop bit for every Write command (Figure 1-1). Toggling the WP pin after the Stop bit will have no effect on the execution of the write cycle. Note: Page write operations are limited to writing 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.
6.2
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

7.0 ACKNOWLEDGE POLLING
FIGURE 7-1:
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 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, then no ACK will be returned. If no ACK is returned, the Start bit and control byte must be resent. If the cycle is complete, then the device will return the ACK and the master can then proceed with the next Read or Write command. See Figure 7-1 for flow diagram.

8.0 READ OPERATION
8.2 Random Read
Read operations are initiated in much the same way as write operations with the exception that the R/W bit of the control byte is set to `1'. There are three basic types of read operations: current address read, random read and sequential 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 24XX128 as part of a write operation (R/W bit set to `0'). Once the word address is sent, the master generates a Start condition following the acknowledge. This terminates the write operation, but not before the internal address pointer is set. The master then issues the control byte again, but with the R/W bit set to a `1'. The 24XX128 will then issue an acknowledge and transmit the 8-bit data word. The master will not acknowledge the transfer but does generate a Stop condition, which causes the 24XX128 to discontinue transmission (Figure 8-2). After a random Read command, the internal address counter will point to the address location following the one that was just read.
8.1
Current Address Read
The 24XX128 contains an address counter that maintains the address of the last word accessed, internally incremented by `1'. Therefore, if the previous read access was to address `n' (n is any legal address), the next current address read operation would access data from address n + 1. Upon receipt of the control byte with R/W bit set to `1', the 24XX128 issues an acknowledge and transmits the 8-bit data word. The master will not acknowledge the transfer, but does generate a Stop condition and the 24XX128 discontinues transmission (Figure 8-1).

Sequential reads are initiated in the same way as a random read except that after the 24XX128 transmits the first data byte, the master issues an acknowledge as opposed to the Stop condition used in a random read. This acknowledge directs the 24XX128 to transmit the next sequentially addressed 8-bit word (Figure 8-3). Following the final byte transmitted to the master, the master will NOT generate an acknowledge but will generate a Stop condition. To provide sequential reads, the 24XX128 contains an internal address pointer which is incremented by one at the 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.
