to address N, the READ immediately following would
access data from address N+1. If N=E (where E=4095),
then the counter will ‘wrap around’ to address 0 and
continue to clock out data. After the CAT24FC32A
receives its slave address information (with the R/W bit
set to one), it issues an acknowledge, then transmits the
8 bit byte requested. The master device does not send
an acknowledge, but will generate a STOP condition.
Selective/Random Read
Selective/Random READ operations allow the Master
device to select at random any memory location for a
READ operation. The Master device first performs a
‘dummy’ write operation by sending the START condition,
slave address and byte addresses of the location it
wishes to read. After CAT24FC32A acknowledges, the
Master device sends the START condition and the
slave address again, this time with the R/W bit set to
one. The CAT24FC32A then responds with its
acknowledge and sends the 8-bit byte requested. The
master device does not send an acknowledge but will
generate a STOP condition.
Sequential Read
The Sequential READ operation can be initiated by
either the Immediate Address READ or Selective READ
operations. After the CAT24FC32A sends the initial 8-bit
byte requested, the Master will respond with an
acknowledge which tells the device it requires more
data. The CAT24FC32A will continue to output an 8-bit
byte for each acknowledge sent by the Master. The
operation will terminate when the Master fails to respond
with an acknowledge, thus sending the STOP condition.
The data being transmitted from CAT24FC32A is
outputted sequentially with data from address N followed
by data from address N+1. The READ operation address
counter increments all of the CAT24FC32A address bits
so that the entire memory array can be read during one
operation. After the last memory address is read out, the
counter will ‘wrap around’ and continue to clock out data
bytes.
