W25Q64FV

INSTRUCTIONS
The Standard/Dual/Quad SPI instruction set of the W25Q64FV consists of thirty six basic instructions that
are fully controlled through the SPI bus (see Instruction Set table1-3). Instructions are initiated with the
falling edge of Chip Select (/CS). The first byte of data clocked into the DI input provides the instruction
code. Data on the DI input is sampled on the rising edge of clock with most significant bit (MSB) first.
The QPI instruction set of the W25Q64FV consists of twenty four basic instructions that are fully
controlled through the SPI bus (see Instruction Set table 4). Instructions are initiated with the falling edge
of Chip Select (/CS). The first byte of data clocked through IO[3:0] pins provides the instruction code.
Data on all four IO pins are sampled on the rising edge of clock with most significant bit (MSB) first. All
QPI instructions, addresses, data and dummy bytes are using all four IO pins to transfer every byte of
data with every two serial clocks (CLK).
Instructions vary in length from a single byte to several bytes and may be followed by address bytes, data
bytes, du mmy bytes (don’t care), and in some cases, a combination. Instructions are completed with the
rising edge of edge /CS. Clock relative timing diagrams for each instruction are included in figures 5
through 42. All read instructions can be completed after any clocked bit. However, all instructions that
Write, Program or Erase must complete on a byte boundary (/CS driven high after a full 8-bits have been
clocked) otherwise the instruction will be ignored. This feature further protects the device from inadvertent
writes. Additionally, while the memory is being programmed or erased, or when the Status Register is
being written, all instructions except for Read Status Register will be ignored until the program or erase
cycle has completed.
