Data Sheet
Instructions
Instructions are used to read, write (Erase and Program), and configure the SST25WF512/010/020/
040. 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
complete instructions are provided in Tables 9 and 10. 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 signifi-
cant 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.
