Instructions
Instructions are used to Read, Write (Erase and Program), and
configure the F25L016A. The instruction bus cycles are 8 bits
each for commands (Op Code), data, and addresses. Prior to
executing any Byte-Program, Sector-Erase, Block-Erase, or
Chip-Erase instructions, the Write-Enable (WREN) instruction
must be executed first. The complete list of the 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 significant bit. CE must be driven

One bus cycle is eight clock periods.
Sector addresses: use AMS-A12, remaining addresses can be V
Prior to any Byte-Program, Sector-Erase , Block-Erase ,or Chip-Erase operation, the Write-Enable (WREN) instruction must be
executed.
To continue programming to the next sequential address location, enter the 8-bit command, ADH, followed by the data to be
programmed.
The Read-Status-Register is continuous with ongoing clock cycles until terminated by a low to high transition on CE .
The Enable-Write-Status-Register (EWSR) instruction and the Write-Status-Register (WRSR) instruction must work in conjunction
of each other. The WRSR instruction must be executed immediately (very next bus cycle) after the EWSR instruction to make both
instructions effective.
The Read-Electronic-Signature is continuous with on going clock cycles until terminated by a low to high transition on CE .

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 the standby mode.
Instruction commands (Op Code), addresses, and data are all
input from the most significant bit (MSB) first.
