SIGNAL DESCRIPTION

Serial Data Output (DO). This output signal is used to

transfer data serially out of the device. Data is shifted out on

the falling edge of Serial Clock (C).

The DO pin is also used as an input pin when the Fast Read

Dual Input-Output Function is executed.

Serial Data Input / Output (DIO). This input signal is used to

transfer data serially into the device. It receives instructions,

addresses, and the data to be programmed. Values are

latched on the rising edge of Serial Clock (C).

The DIO pin is also used as an output pin when the Fast

Read Dual Output function and Fast Read Dual Input-Output

function are executed.

Serial Clock (C). This input signal provides the timing of the

serial interface. Instructions, addresses, or data present at

Serial Data Input (DIO) are latched on the rising edge of

Serial Clock (C). Data on Serial Data Output (DO) changes

after the falling edge of Serial Clock (C).

Status Register cycle is in progress, the device will be in the

Standby mode (this is not the Deep Power-down mode).

Driving Chip Select ( ) Low enables the device, placing it in

the active power mode.

After Power-up, a falling edge on Chip Select ( ) is required

prior to the start of any instruction.

Hold (

). The Hold (

) signal is used to pause

HOLD

any serial communications with the device without

deselecting the device.

During the Hold condition, the Serial Data Output (DO) is

high impedance, and Serial Data Input (DIO) and Serial

Clock (C) are Don’t Care. To start the Hold condition, the

device must be selected, with Chip Select ( ) driven Low.

Write Protect ( ). The main purpose of this input signal is

to freeze the size of the area of memory that is protected

against program or erase instructions (as specified by the

values in the BP2, BP1 and BP0 bits of the Status Register).

Chip Select ( ). When this input signal is High, the device

is deselected and Serial Data Output (DO) is at high

impedance. Unless an internal Program, Erase or Write

SPI MODES

the falling edge of Serial Clock (C).

These devices can be driven by a microcontroller with its SPI

peripheral running in either of the two following modes:

– CPOL=0, CPHA=0

– CPOL=1, CPHA=1

For these two modes, input data is latched in on the rising

edge of Serial Clock (C), and output data is available from

The difference between the two modes, as shown in Figure 2,

is the clock polarity when the bus master is in Stand-by mode

and not transferring data:

– C remains at 0 for (CPOL=0, CPHA=0)

– C remains at 1 for (CPOL=1, CPHA=1)
