... The device has a page write capability for bytes of data. Functional address lines allow the connection eight 24VL014 devices on the same bus for Kbits of contiguous EEPROM memory. The device is available in the standard 8-pin PDIP, 8-pin SOIC (150 mil), TSSOP, 2x3 TDFN and MSOP packages ...

... The SCL input is used to synchronize the data transfer to and from the device. 2.3 A0, A1, A2 The A0, A1 and A2 inputs are used by the 24VL014 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. ...

... The bus has to be controlled by a master device that generates the Serial Clock (SCL), controls the bus access and generates the Start and Stop conditions, while the 24VL014 works as slave. Both master and slave can operate as transmitter or receiver, but the master device determines which mode is activated ...

... The master device must generate an extra clock pulse which is associated with this Acknowledge bit. Note: The 24VL014 does not generate any Acknowledge programming cycle is in progress. The device that acknowledges has to pull down the ...

... SDA bus, checking the control byte being transmitted. Upon receiving a ‘1010’ code and appro- priate Chip Select bits, the slave device outputs an Acknowledge signal on the SDA line. Depending on the state of the R/W bit, the 24VL014 will select a read or write operation. DS22129A-page 8 FIGURE 5-1: ...

... But instead of generating a Stop condition, the master transmits additional data bytes to the 24VL014 that are temporarily stored in the on-chip page buffer and will be written into the memory once the master has transmitted a Stop condition. ...

... 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 and ACK polling can be initiated immediately ...

... Sequential Read Sequential reads are initiated in the same way as a random read except that after the 24VL014 transmits the first data byte, the master issues an acknowledge as opposed to a Stop condition in a random read. This directs the 24VL014 to transmit the next sequentially addressed 8-bit word (Figure 8-3) ...
