SPI NOR
PN25F08
SI becomes IO0 an input and output during Dual and Quad Instructions for receiving instructions, addresses, and
data to be programmed (values latched on rising edge of serial SCK clock signal) as well as shifting out data (on the
falling edge of SCK).
Serial Data Output (SO)/IO1
This output signal is used to transfer data serially out of the device. Data is shifted out on the falling edge of the
serial SCK clock signal.
SO becomes IO1 an input and output during Dual and Quad Instructions for receiving instructions, addresses, and
data to be programmed (values latched on rising edge of serial SCK clock signal) as well as shifting out data (on the
falling edge of SCK).
Write Protect (/WP)/IO2
When /WP is driven Low (VIL), while the Status Register Protect bits (SRP1 and SRP0) of the Status Registers (SR2[0]
and SR1[7]) are set to 0 and 1 respectively, it is not possible to write to the Status Registers. This prevents any
alteration of the Status Registers. As a consequence, all the data bytes in the memory area that are protected by
the Block Protect, TB, SEC, and CMP bits in the status registers, are also hardware protected against data
modification while /WP remains Low. The /WP function is not available when the Quad mode is enabled (QE) in
Status Register 2 (SR2[1]=1).
The /WP function is replaced by IO2 for input and output during Quad mode for receiving addresses, and data to be
programmed (values are latched on rising edge of the SCK signal) as well as shifting out data (on the falling edge of
SCK). /WP has an internal pull-up resistance; when unconnected; /WP is at VIH and may be left unconnected in the
host system if not used for Quad mode.
HOLD (/HOLD)/IO3
The /HOLD signal goes low to stop any serial communications with the device, but doesn’t stop the operation of
write status register, programming, or erasing in progress.The operation of HOLD, need /CS keep low, and starts on
falling edge of the /HOLD signal, with CLK signal being low (if CLK is not being low, HOLD operation will not start
until CLK being low). The HOLD condition ends on rising edge of /HOLD signal with CLK being low (If CLK is not being
low, HOLD operation will not end until CLK being low).
The Hold condition starts on the falling edge of the Hold (/HOLD) signal, provided that this coincides with SCK being
at the logic low state. If the falling edge does not coincide with the SCK signal being at the logic low state, the Hold
condition starts whenever the SCK signal reaches the logic low state. Taking the /HOLD signal to the logic low state
does not terminate any Write, Program or Erase operation that is currently in progress.
VCC Power Supply
VCC is the supply voltage. is the single voltage used for all device functions including read, program, and erase.
VSS Ground
VSS is the reference for the VCC supply voltage.
