Pin Description
SI: The serial data input pin accepts op−codes, addresses
and data. In SPI modes (0,0) and (1,1) input data is latched
on the rising edge of the SCK clock input.
SO: The serial data output pin is used to transfer data out of
the device. In SPI modes (0,0) and (1,1) data is shifted out
on the falling edge of the SCK clock.
SCK: The serial clock input pin accepts the clock provided
by the host and used for synchronizing communication
between host and NV25320WF.
CS: The chip select input pin is used to enable/disable the
NV25320WF. When CS is high, the SO output is tri−stated
(high impedance) and the device is in Standby Mode (unless
an internal write operation is in progress). Every
communication session between host and NV25320WF must
be preceded by a high to low transition and concluded with
a low to high transition of the CS input.
WP: The write protect input pin will allow all write
operations to the device when held high. When WP pin is
tied low and the WPEN bit in the Status Register (refer to
Status Register description, later in this Data Sheet) is set to
“1”, writing to the Status Register is disabled.
HOLD: The HOLD input pin is used to pause transmission
between host and NV25320WF, without having to
retransmit the entire sequence at a later time. To pause,
HOLD must be taken low and to resume it must be taken
back high, with the SCK input low during both transitions.
When not used for pausing, the HOLD input should be tied
to VCC, either directly or through a resistor.
Functional Description
The NV25320WF device supports the Serial Peripheral
Interface (SPI) bus protocol, modes (0,0) and (1,1). The
device contains an 8−bit instruction register. The instruction
set and associated op−codes are listed in Table 7.
Reading data stored in the NV25320WF is accomplished
by simply providing the READ command and an address.
Writing to the NV25320WF, in addition to a WRITE
command, address and data, also requires enabling the
device for writing by first setting certain bits in a Status
Register, as will be explained later.
After a high to low transition on the CS input pin, the
NV25320WF will accept any one of the six instruction
op−codes listed in Table 7 and will ignore all other possible
8−bit combinations. The communication protocol follows
the timing from Figure 2.
