Instructions
Instructions are used to read, write (Erase and Program), and configure the SST25VF080B. The
instruction bus cycles are 8 bits each for commands (Op Code), data, and addresses. Prior to execut-
ing any Byte-Program, Auto Address Increment (AAI) programming, Sector-Erase, Block-Erase, Write-
Status-Register, or Chip-Erase instructions, the Write-Enable (WREN) instruction must be executed
first. The complete list of instructions is provided in Table 5. All instructions are synchronized off a high
to low transition of CE#. Inputs will be accepted on the rising edge of SCK starting with the most signif-
icant bit. CE# must be driven low before an instruction is entered and must be driven high after the last
bit of the instruction has been shifted in (except for Read, Read-ID, and Read-Status-Register instruc-
tions). Any low to high transition on CE#, before receiving the last bit of an instruction bus cycle, will
terminate the instruction in progress and return the device to standby mode. Instruction commands
(Op Code), addresses, and data are all input from the most significant bit (MSB) first.
