Read Operations
The READ operation for the CAT24FC16 is initiated in
the same manner as the write operation with the one
exception that the R/
W
bit is set to a one. Three different
READ operations are possible: Immediate Address
READ, Selective READ and Sequential READ.
Immediate Address Read
The CAT24FC16
’
s address counter contains the address
of the last byte accessed, incremented by one. In other
words, if the last READ or WRITE access was to address
N, the READ immediately following would access data
from address N + 1. If N = 2047 for 24FC16, then the
counter will
‘
wrap around
’
to address 0 and continue to
clock out data. After the CAT24FC16 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 Read
Selective 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 address of the location it wishes to
read. After the CAT24FC16 acknowledge the word
address, the Master device resends the START condition
and the slave address, this time with the R/
W
bit set to
one. The CAT24FC16 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 CAT24FC16 sends the initial 8-bit
data requested, the Master will respond with an
acknowledge which tells the device it requires more
data. The CAT24FC16 will continue to output a byte for
each acknowledge sent by the Master. The operation
with an acknowledge, thus sending the STOP condition.
The data being transmitted from the CAT24FC16 is
outputted sequentially with data from address N followed
by data from address N + 1. The READ operation
address counter increments all of the CAT24FC16
address bits so that the entire memory array can be read
during one operation. If more than the 2047 bytes are
read out, the counter will
“
wrap around
”
and continue to
clock out data bytes.
