Parallel Mode
In parallel mode, the maximum SCK clock frequency is 10 MHz. The device requires a single clock cycle
instead of eight clock cycles to access the next data byte. The method of memory content output will be the
same compared to the serial mode. The only difference is that a byte of data is output per clock cycle instead
of a single bit. In this case, the manufacturer identification will be output during the first byte cycle and the
device identification during the second and third byte cycles out of the PO7-PO0 serial output pins. To read ID
in parallel mode requires a Parallel Mode Entry command (55h) to be issued before the RDID command.
Once in the parallel mode, the flash memory will not exit parallel mode until a Parallel Mode Exit (45h)
command is given to the flash device, or upon power down/power up sequence.
