Data Sheet
High-Speed-Read (66/80 MHz)
The High-Speed-Read instruction supporting up to 66 MHz
(for
SST25VF040B-80-xx-xxxx) Read is initiated by executing
an 8-bit command, 0BH, followed by address bits [A23-A0]
and a dummy byte. CE# must remain active low for the
duration of the High-Speed-Read cycle. See Figure 6 for
the High-Speed-Read sequence.
Following a dummy cycle, the High-Speed-Read instruc-
tion outputs the data starting from the specified address
location. The data output stream is continuous through all

addresses until terminated by a low to high transition on
CE#. The internal address pointer will automatically incre-
ment until the highest 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. Once the data from address
location FFFFFH has been read, the next output will be
from address location 00000H.
