PIN DESCRIPTIONS
Serial Output (SO)
SO is a push/pull serial data output pin. During a read
cycle, data is shifted out on this pin. Data is clocked out
by the falling edge of the serial clock.
Serial Input (SI)
SI is the serial data input pin. All opcodes, byte
addresses, and data to be written to the memory are
input on this pin. Data is latched by the rising edge of
the serial clock.
Serial Clock (SCK)
The Serial Clock controls the serial bus timing for data
input and output. Opcodes, addresses, or data present
on the SI pin are latched on the rising edge of the clock
input, while data on the SO pin change after the falling
edge of the clock input.
Chip Select (CS)
When CS is HIGH, the X25040 is deselected, the SO
output pin is at high impedance and unless an internal
write operation is underway, the X25040 will be in the
standby power mode. CS LOW enables the X25040,
placing it in the active power mode. It should be noted
that after power-up, a HIGH to LOW transition on CS is
required prior to the start of any operation.
Write Protect (WP)
When WP is LOW, nonvolatile writes to the X25040 are
disabled, but the part otherwise functions normally.
When WP is held HIGH, all functions, including nonvol-
atile writes, operate normally. WP going LOW while CS
is still LOW will interrupt a write to the X25040. If the
internal write cycle has already been initiated, WP
going LOW will have no affect on a write.
Hold (HOLD)
HOLD is used in conjunction with the CS pin to select
the device. Once the part is selected and a serial
sequence is underway, HOLD may be used to pause
the serial communication with the controller, without
resetting the serial sequence. To pause, HOLD must
be brought LOW while SCK is LOW. To resume com-
munication, HOLD is brought HIGH, again while SCK
is LOW. If the pause feature is not used, HOLD should
be held HIGH at all times.
