Data Sheet
Read (20 MHz)
The Read instruction outputs the data starting from the
specified address location. The data output stream is con-
tinuous 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 will automatically increment to the
beginning (wrap-around) of the address space, i.e. for
4 Mbit density, once the data from address location
7FFFFH had been read, the next output will be from
address location 00000H.
The Read instruction is initiated by executing an 8-bit com-
mand, 03H, followed by address bits [A

]. CE# must
remain active low for the duration of the Read cycle. See
