DEVICE OPERATION (CONTINUED)
READ COMMAND (READ DATA) OPERATION
The Read Data (READ) instruction is used to read
memory data of a IS25CQ032 under normal mode
running up to 33 MHz.
The READ instruction code is transmitted via the Sl
line, followed by three address bytes (A23 - A0) of the
first memory location to be read. A total of 24 address
bits are shifted in, but only A
address) - A0 are decoded. The remaining bits (A23 –
A
any memory location. Upon completion, any data on
the Sl will be ignored. Refer to Table 13 for the related
Address Key.
The first byte data (D7 - D0) addressed is then shifted

out on the SO line, MSb first. A single byte of data, or
up to the whole memory array, can be read out in one
READ instruction. The address is automatically
incremented after each byte of data is shifted out. The
read operation can be terminated at any time by driving

counter will roll over to the 000000h address, allowing
the entire memory to be read in one continuous READ
instruction.
If a Read Data instruction is issued while an Erase,
Program or Write cycle is in process (BUSY=1) the
instruction is ignored and will not have any effects on the
