Data Sheet
High-Speed-Read (50 MHz)
The High-Speed-Read instruction supporting up to 50 MHz
Read is initiated by executing an 8-bit command, 0BH, fol-
lowed by address bits [A
must remain active low for the duration of the High-Speed-
Read cycle. See Figure 5 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.
