Instructions
Instructions are used to read, write (Erase and Program), and configure the SST25WF080. The
instruction bus cycles are 8 bits each for commands (Op Code), data, and addresses. The Write-
Enable (WREN) instruction must be executed prior to Byte-Program, Auto Address Increment (AAI)
programming, Sector-Erase, Block-Erase, Write-Status-Register, or Chip-Erase instructions. The com-
plete instructions are provided in Table 6. 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 significant 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 instructions). 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.

One bus cycle is eight clock periods.
Address bits above the most significant bit of each density can be V IL or V IH .
4 KByte Sector-Erase addresses: use A MS -A 12, remaining addresses are don’t care but must be set either at V IL or V IH.
32 KByte Block-Erase addresses: use A MS -A 15, remaining addresses are don’t care but must be set either at V IL or V IH.
