Read (25/33 MHz)
The Read instruction, 03H, supports up to 25 MHz (for SST25VF080B-50-xx-xxxx) or 33 MHz (for
SST25VF080B-80-xx-xxxx) Read. The device 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 increment until the highest memory
address is reached. Once the highest memory address is reached, the address pointer will automati-
cally increment to the beginning (wrap-around) of the address space. Once the data from address
location 1FFFFFH has been read, the next output will be from address location 000000H.
The Read instruction is initiated by executing an 8-bit command, 03H, followed by address bits [A23-
A0]. CE# must remain active low for the duration of the Read cycle. See Figure 5 for the Read
sequence.
