8 Mbit SPI Serial Flash
SST25LF080A
Read (20 MHz)
The Read instruction supports up to 20 MHz, it outputs the
data starting from the specified address location. The data
output stream is continuous through all addresses until ter-
minated by a low to high transition on CE#. The internal
address pointer will automatically increment until the high-
est memory address is reached. Once the highest memory
address is reached, the address pointer will automatically
increment to the beginning (wrap-around) of the address

space, i.e. for 8 Mbit density, once the data from address
location 0FFFFFH had been read, the next output will be
from address location 000000H.
The Read instruction is initiated by executing an 8-bit com-
mand, 03H, followed by address bits [A23-A0]. CE# must
remain active low for the duration of the Read cycle. See
Figure 4 for the Read sequence.
