output, and sends additional clock pulses so that

the device continues to output the next byte in

sequence. To terminate the stream of bytes, the

bus master must

not acknowledge the last byte,

and

must generate a Stop condition, as shown in

Figure 8.

The

output

data

comes

from

consecutive

addresses, with the internal address counter

automatically incremented after each byte output.

After the last memory address, the address

counter ‘rolls-over’, and the device continues to

output data from memory address 00h.

Acknowledge in Read Mode

For all Read commands, the device waits, after

each byte read, for an acknowledgment during the

9th bit time. If the bus master does not drive Serial

Data (SDA) Low during this time, the device

terminates the data transfer and switches to its

Stand-by mode.

ORDERING INFORMATION

Devices are shipped from the factory with the

memory content set at all 1s (FFh).

The notation used for the device number is as

shown in Table 8. For a list of available options

(speed, package, etc.) or for further information on

any aspect of this device, please contact your

nearest ST Sales Office.
