... A and 1 mA, respectively. The device has a page write capability for bytes of data. Functional address lines allow the connection eight 24AA014/24LC014 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 DFN and MSOP packages ...

... SDA bus, checking the control byte being transmitted. Upon receiving a ‘1010’ code and appropriate Chip Select bits, the slave device out- puts an Acknowledge signal on the SDA line. Depend- ing on the state of the R/W bit, the 24AA014/24LC014 will select a read or write operation. DS21809C-page 6 FIGURE 5-1: ...

... 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 ...

... Upon receipt of the slave address with the R/W bit set to ‘1’, the 24AA014/24LC014 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 24AA014/24LC014 discontinues transmission (Figure 8-1) ...
