ADDRESS
Immediate/Current Address Read
The CAT1026 and CAT1027 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. For N = E = 255, the counter will
wrap around to zero and continue to clock out valid
data. After the CAT1026and CAT1027 receive 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 the
CAT1026 and CAT1027 acknowledges, the Master
device sends the START condition and the slave
address again, this time with the R/W
bit set to one.
The CAT1026 and CAT1027 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 CAT1026 and CAT1027 sends the
inital 8-bit byte requested, the Master will responds with
an acknowledge which tells the device it requires more
data. The CAT1026 and CAT1027 will continue to
output an 8-bit byte for each acknowledge, thus sending
the STOP condition.
The data being transmitted from the CAT1026 and
CAT1027 is sent sequentially with the data from
address N followed by data from address N + 1. The
READ operation address counter increments all of the
CAT1026 and CAT1027 address bits so that the entire
memory array can be read during one operation.
