Random Access Read
Random Address READ operation allows the master
device to access any memory location in a random fashion.
This operation involves a two-step process. First, the
master device generates a START condition and initiates
Device Addressing Byte with a WRITE operation (read/
write bit sets to “0”), followed by the address of the data
word the master device is to READ. This procedure stores
the desired address of data word to the internal address
counter of the IS24C01-3.
After the data word address ACKnowledge is received by
the master device, the master device now initiates a
CURRENT ADDRESS READ by sending Device
Addressing Byte with a READ operation (read/write bit
sets to “1”). The IS24C01-3 responds with an ACKnowledge
and transmits the eight data bits stored at the address
location where the master device is to READ. At this point,
the master device terminates the operation by pulling
ACKnowledge HIGH (lack of ACKnowledge) indicating the
last data word to be read, followed by a STOP condition.
(Refer to Figure 8. Random Address Read Diagram.)
Sequential Read
Sequential Reads can be initiated as either a Current
Address Read or Random Address Read. The first data
word is transmitted as with the other byte read modes, the
master device now responds with an ACKnowledge indicating
that it requires additional data from the IS24C01-3.
The
IS24C01-3 continues to output data for each ACKnowledge
received. the master device terminates the sequential
READ operation by pulling ACKnowledge HIGH (lack of
ACKnowledge) indicating the last data word to be read,
followed by a STOP condition.
The data output is sequential, with the data from
address n followed by the date from address n+1, ... etc.
The address counter increments by one automatically,
allowing the entire memory contents to be serially read
during sequential read operation. When the memory
address boundry (address 127) is reached, the address
counter “rolls over” to address 0, and the IS24C01-3
continues to output data for each ACKnowledge received.
(Refer to Figure 9. Sequential Read Operation Starting
with a Random Address READ Diagram.)
