24LLC16
16K-Bit-Serial EEPROM
OVERVIEW
The 24LLC16 serial EEPROM has a 16 Kbits (2,048 bytes) capacity, supporting the standard I2CTM-bus serial interface. It is fabricated using CERAMATE's most advanced CMOS technology. One of its major features is a hardware-based write protection circuit for the entire memory area. Hardware-based write protection is controlled by the state of the write-protect (WP) pin. Using one-page write mode, you can load up to 16 bytes of data into the EEPROM in a single write operation. Another significant feature of the 24LLC1616 is its support for fast mode and standard mode.

FUNCTION DESCRIPTION
I C-BUS INTERFACE
2 The 24LLC16 supports the I C-bus serial interface data transmission protocol. The two-wire bus consists of a serial data line (SDA) and a serial clock line (SCL). The SDA and the SCL lines must be connected to VCC by a pull-up resistor that is located somewhere on the bus. 2
Any device that puts data onto the bus is defined as a "transmitter" and any device that gets data from the bus is a "receiver." The bus is controlled by a master device which generates the serial clock and start/stop conditions, 2 controlling bus access. Only one 24LLC16 devices can be connected to the I C-bus as slaves (see Figure 56). Both the master and slaves can operate as a transmitter or a receiver, but the master device determines which bus operating mode would be active.

16K-Bit-Serial EEPROM
I2C-BUS PROTOCOLS Here are several rules for I C-bus transfers: -- A new data transfer can be initiated only when the bus is currently not busy. -- MSB is always transferred first in transmitting data. -- During a data transfer, the data line (SDA) must remains stable whenever the clock line (SCL) is High.
2 The I C-bus interface supports the following communication protocols: 2
* * *
Bus not busy: The SDA and the SCL lines remain in High level when the bus is not active. Start condition: A start condition is initiated by a High-to-Low transition of the SDA line while SCL remains in High level. All bus commands must be preceded by a start condition. Stop condition: A stop condition is initiated by a Low-to-High transition of the SDA line while SCL remains in High level. All bus operations must be completed by a stop condition (see Figure 5-7).

Stop Condition
Figure 5-7. Data Transmission Sequence * Data valid: Following a start condition, the data becomes valid if the data line remains stable for the duration of the High period of SCL. New data must be put onto the bus while SCL is Low. Bus timing is one clock pulse per data bit. The number of data bytes to be transferred is determined by the master device. The total number of bytes that can be transferred in one operation is theoretically unlimited. ACK (Acknowledge): An ACK signal indicates that a data transfer is completed successfully. The transmitter (the master or the slave) releases the bus after transmitting eight bits. During the 9th clock, which the master generates, the receiver pulls the SDA line low to acknowledge that it has successfully received the eight bits of data (see Figure 5-8). But the slave does not send an ACK if an internal write cycle is still in progress. In data read operations, the slave releases the SDA line after transmitting 8 bits of data and then monitors the line for an ACK signal during the 9th clock period. If an ACK is detected, the slave will continue to transmit data. If an ACK is not detected, the slave terminates data transmission and waits for a stop condition to be issued by the master before returning to its stand-by mode.

Figure 5-8. Acknowledge Response From Receiver * Slave Address: After the master initiates a start condition, it must output the address of the device to be accessed. The most significant four bits of the slave address are called the "device identifier." The identifier for the 24LLC16 is "1010B". The next three bits (B2, B1, B0) are for block selection. They are used by the master to select which of the blocks of internal memory (1 block=256 words) are to be accessed. (see Table 5-2 below.) These bits are in effect the three most significant bits of the word address Read/Write: The final (eighth) bit of the slave address defines the type of operation to be performed. If the R/W bit is "1", a read operation is executed. If it is "0", a write operation is executed. Table 5-2.

BYTE WRITE OPERATION In a complete byte write operation, the master transmits the slave address, word address, and one data byte to the 24LLC16 slave device (see Figure 5-9).

Figure 5-9. Byte Write Operation Following a start condition, the master sends the device identifier (4 bits), three "don't care" bits, and an R/W bit set to "0" onto the bus. Then the addressed 24LLC16 generates an ACK, and waits for the next byte. The next byte to be transmitted by the master is the word address. This 8-bit address is written into the word address pointer of the 24LLC16 When the 24LLC16 receives the word address, it responds by issuing an ACK and then waits for the next 8bit data. When it receives the data byte, the 24LLC16 again responds with an ACK. The master terminates the transfer by generating a Stop condition, at which time the 24LLC16 begins the internal write cycle. While the internal write cycle is in progress, all 24LLC16 inputs are disabled and the 24LLC16 does not respond to any additional request from the master.

PAGE WRITE OPERATION The 24LLC16 can also perform 16-byte page write operation. A page write operation is initiated in the same way as a byte write operation. However, instead of finishing the write operation after the first data byte is transferred, the master can transmit up to 15 additional bytes. The 24LLC166 responds with an ACK each time it receives a complete byte of data (see Figure 5-10).

Figure 5-10. Page Write Operation The 24LLC16 automatically increments the word address pointer each time it receives a complete data byte. When one byte is received, the internal word address pointer increments to the next address so that the next data byte can be received. If the master transmits more than 16 bytes before it generates a stop condition to end the page write operation, the 24LLC16 word address pointer value "rolls over" and the previously received data is overwritten. If the master transmits less than 16 bytes and generates a stop condition, the 24LLC16 writes the received data to the corresponding EEPROM address. During a page write operation, all inputs are disabled and there would be no response to additional requests from the master until the internal write cycle is completed.

POLLING FOR AN ACK SIGNAL When the master issues a stop condition to initiate a write cycle, the 24LLC16 starts an internal write cycle. The master can then immediately begin polling for an ACK from the slave device to determine whether the write cycle is completed. To poll for an ACK signal in a write operation, the master issues a start condition followed by the slave address. As long as the 24LLC16 remains busy with the write operation, no ACK is returned. When the 24LLC16 completes the write operation, it returns an ACK and the master can then proceed with the next read or write operation (see Figure 5-11).

24LLC16
16K-Bit-Serial EEPROM
HARDWARE-BASED WRITE PROTECTION You can also write-protect the entire memory area of the 24LLC16 This method of write protection is controlled by the state of the Write Protect (WP) pin. When the WP pin is connected to VCC, any attempt to write a value to the memory is ignored. The 24LLC16 will acknowledge slave and word address, but it will not generate an acknowledge after receiving first byte of data. In this situation the write cycle will not be started when a stop condition is generated. By connecting the WP pin to VSS, the write function is allowed for the entire memory. These write protection features effectively change the EEPROM to a ROM in order to protect data from being overwritten. Whenever the write function is disabled, a slave address and a word address are acknowledged on the bus, but data bytes are not acknowledged. The WP pin is internally pulled down to VSS. CURRENT ADDRESS BYTE READ OPERATION The internal word address pointer maintains the address of the last word accessed, incremented by one. Therefore, if the last access (either read or write) was to the address "n", the next read operation would access data at address "n+1". When the 24LLC16 receives a slave address with the R/W bit set to "1", it issues an ACK and sends eight bits of data. In a current address byte read operation the master does not acknowledge the data, and it generates a Stop condition, forcing the 24LLC16 to stop the transmission (see Figure 5-12).

16K-Bit-Serial EEPROM
RANDOM ADDRESS BYTE READ OPERATION Using random read operations, the master can access any memory location at any time. Before it issues the slave address with the R/W bit set to "1", the master must first perform a "dummy" write operation. This operation is performed in the following steps: 1. The master first issues a start condition, the slave address, and the word address to be read. (This step sets the internal word address pointer of the 24LLC16 to the desired address.) 2. When the master receives an ACK for the word address, it immediately re-issues a start condition followed by another slave address, with the R/W bit set to "1". 3. The 24LLC16 then sends an ACK and the 8-bit data stored at the pointed address. 4. At this point, the master does not acknowledge the transmission, generating a stop condition. 5. The 24LLC16 stops transmitting data and reverts to stand-by mode (see Figure 5-13).

16K-Bit-Serial EEPROM
SEQUENTIAL READ OPERATION Sequential read operations can be performed in two ways: current address sequential read operation, and random address sequential read operation. The first data is sent in either of the two ways, current address byte read operation or random address byte read operation described earlier. If the master responds with an ACK, the 24LLC16 continues transmitting data. If the master does not issue an ACK, generating a stop condition, the slave stops transmission, ending the sequential read operation. Using this method, data is output sequentially from address "n" followed by address "n+1". The word address pointer for read operations increments to all word addresses, allowing the entire EEPROM to be read sequentially in a single operation. After the entire EEPROM is read, the word address pointer "rolls over" and the 24LLC16 continues to transmit data for each ACK it receives from the master (see Figure 5-14).
