High-Speed-Read (66/80 MHz)
The High-Speed-Read instruction supporting up to 66 MHz (for SST25VF080B-50-xx-xxxx) or 80 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 instruction outputs the data starting from the speci-
fied 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 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. Once the data from
address location FFFFFH has been read, the next output will be from address location 00000H.
