Data Sheet
Instructions
Instructions are used to read, write (Erase and Program), and configure the SST25VF032B. The
instruction bus cycles are 8 bits each for commands (Op Code), data, and addresses. The Write-
Enable (WREN) instruction must be executed prior any Byte-Program, Auto Address Increment (AAI)
programming, Sector-Erase, Block-Erase, Write-Status-Register, or Chip-Erase instructions. The com-
plete 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 ris-
ing 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.
