Sequential Read
This operation can be used after a Current Ad-
dress Read or a Random Address Read. The bus
master
does
acknowledge the data byte output,
and sends additional clock pulses so that the de-
vice 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
The output data comes from consecutive address-
es, 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
9
th
bit time. If the bus master does not drive Serial
Data (SDA) Low during this time, the device termi-
nates the data transfer and switches to its Stand-
by mode.
INITIAL DELIVERY STATE
The device is delivered with the memory array
erased: all bits are set to 1 (each byte contains
FFh).
