Data Sheet
Fast-Read Dual-Output (75 MHz)
The Fast-Read Dual-Output (3BH) instruction outputs data up to 75 MHz from the SIO 0 and SIO 1 pins.
To initiate the instruction, execute an 8-bit command (3BH) followed by address bits A23-A0 and a
dummy byte on SI/SIO 0 . Following a dummy cycle, the Fast-Read Dual-Output instruction outputs the
data starting from the specified address location on the SIO 1 and SIO 0 lines. SIO 1 outputs, per clock
sequence, odd data bits D7, D5, D3, and D1; and SIO 0 outputs even data bits D6, D4, D2, and D0.
CE# must remain active low for the duration of the Fast-Read Dual-Output instruction cycle. See Fig-
ure 8 for the Fast-Read Dual-Output sequence.
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 highest memory address is
reached. Once the highest memory address is reached, the address pointer automatically increments
to the beginning (wraparound) of the address space. for 64 Mbit density, once the data from address
location 7FFFFFH has been read the next output will be from address location 000000H.
