CAT25320
Pin Description
pausing, the HOLD input should be tied to VCC, either
directly or through a resistor.
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 CAT25320.
CS: The chip select input pin is used to enable/disable the
CAT25320. 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 CAT25320 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 CAT25320, 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
Functional Description
The CAT25320 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 CAT25320 is accomplished by
simply providing the READ command and an address.
Writing to the CAT25320, 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
CAT25320 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.

allowed to protect a quarter, one half or the entire memory,
by setting these bits according to Table 9. The protected
blocks then become read−only.
The WPEN (Write Protect Enable) bit acts as an enable for
the WP pin. Hardware write protection is enabled when the
WP pin is low and the WPEN bit is 1. This condition
prevents writing to the status register and to the block
protected sections of memory. While hardware write
protection is active, only the non−block protected memory
can be written. Hardware write protection is disabled when
the WP pin is high or the WPEN bit is 0. The WPEN bit, WP
pin and WEL bit combine to either permit or inhibit Write
operations, as detailed in Table 10.
The Status Register, as shown in Table 8, contains a
number of status and control bits.
The RDY (Ready) bit indicates whether the device is busy
with a write operation. This bit is automatically set to 1 during
an internal write cycle, and reset to 0 when the device is ready
to accept commands. For the host, this bit is read only.
The WEL (Write Enable Latch) bit is set/reset by the
WREN/WRDI commands. When set to 1, the device is in a
Write Enable state and when set to 0, the device is in a Write
Disable state.
The BP0 and BP1 (Block Protect) bits determine which
blocks are currently write protected. They are set by the user
with the WRSR command and are non−volatile. The user is

CAT25320
WRITE OPERATIONS
Write Enable and Write Disable
The CAT25320 device powers up into a write disable
state. The device contains a Write Enable Latch (WEL)
which must be set before attempting to write to the memory
array or to the status register. In addition, the address of the
memory location(s) to be written must be outside the
protected area, as defined by BP0 and BP1 bits from the
status register.
The internal Write Enable Latch and the corresponding
Status Register WEL bit are set by sending the WREN
instruction to the CAT25320. Care must be taken to take the
CS input high after the WREN instruction, as otherwise the
Write Enable Latch will not be properly set. WREN timing
is illustrated in Figure 3. The WREN instruction must be
sent prior to any WRITE or WRSR instruction.
The internal write enable latch is reset by sending the
WRDI instruction as shown in Figure 4. Disabling write
operations by resetting the WEL bit, will protect the device
against inadvertent writes.

Byte Write
Page Write
Once the WEL bit is set, the user may execute a write
sequence, by sending a WRITE instruction, a 16−bit address
and data as shown in Figure 5. Only 12 significant address
bits are used by the CAT25320. The rest are don’t care bits,
as shown in Table 11. Internal programming will start after
the low to high CS transition. During an internal write cycle,
all commands, except for RDSR (Read Status Register) will
be ignored. The RDY bit will indicate if the internal write
cycle is in progress (RDY high), or the device is ready to
accept commands (RDY low).
After sending the first data byte to the CAT25320, the host
may continue sending data, up to a total of 32 bytes,
according to timing shown in Figure 6. After each data byte,
the lower order address bits are automatically incremented,
while the higher order address bits (page address) remain
unchanged. If during this process the end of page is
exceeded, then loading will “roll over” to the first byte in the
page, thus possibly overwriting previously loaded data.
Following completion of the write cycle, the CAT25320 is
automatically returned to the write disable state.

Write Status Register
Write Protection
The Status Register is written by sending a WRSR
instruction according to timing shown in Figure 7. Only bits
2, 3 and 7 can be written using the WRSR command.
The Write Protect (WP) pin can be used to protect the
Block Protect bits BP0 and BP1 against being inadvertently
altered. When WP is low and the WPEN bit is set to “1”,
write operations to the Status Register are inhibited. WP
going low while CS is still low will interrupt a write to the
status register. If the internal write cycle has already been
initiated, WP going low will have no effect on any write
operation to the Status Register. The WP pin function is
blocked when the WPEN bit is set to “0”. The WP input
timing is shown in Figure 8.

CAT25320
READ OPERATIONS
Read from Memory Array
Read Status Register
To read from memory, the host sends a READ instruction
followed by a 16−bit address (see Table 11 for the number
of significant address bits).
After receiving the last address bit, the CAT25320 will
respond by shifting out data on the SO pin (as shown in
Figure 9). Sequentially stored data can be read out by simply
continuing to run the clock. The internal address pointer is
automatically incremented to the next higher address as data
is shifted out. After reaching the highest memory address,
the address counter “rolls over” to the lowest memory
address, and the read cycle can be continued indefinitely.
The read operation is terminated by taking CS high.
To read the status register, the host simply sends a RDSR
command. After receiving the last bit of the command, the
CAT25320 will shift out the contents of the status register on
the SO pin (Figure 10). The status register may be read at any
time, including during an internal write cycle. While the
internal write cycle is in progress, the RDSR command will
output the full content of the status register (New product,
Rev. F) or the RDY (Ready) bit only (i.e., data out = FFh) for
previous product revision C (Mature product). For easy
detection of the internal write cycle completion, both during
writing to the memory array and to the status register, we
recommend sampling the RDY bit only through the polling
routine. After detecting the RDY bit “0”, the next RDSR
instruction will always output the expected content of the
status register.

Hold Operation
below the POR trigger level. This bi−directional POR
behavior protects the device against ‘brown−out’ failure
following a temporary loss of power.
The CAT25320 device powers up in a write disable state
and in a low power standby mode. A WREN instruction
must be issued prior to any writes to the device.
After power up, the CS pin must be brought low to enter
a ready state and receive an instruction. After a successful
byte/page write or status register write, the device goes into
a write disable mode. The CS input must be set high after the
proper number of clock cycles to start the internal write
cycle. Access to the memory array during an internal write
cycle is ignored and programming is continued. Any invalid
op−code will be ignored and the serial output pin (SO) will
remain in the high impedance state.
The HOLD input can be used to pause communication
between host and CAT25320. To pause, HOLD must be
taken low while SCK is low (Figure 11). During the hold
condition the device must remain selected (CS low). During
the pause, the data output pin (SO) is tri−stated (high
impedance) and SI transitions are ignored. To resume
communication, HOLD must be taken high while SCK is low.
Design Considerations
The CAT25320 device incorporates Power−On Reset
(POR) circuitry which protects the internal logic against
powering up in the wrong state. The device will power up
into Standby mode after VCC exceeds the POR trigger level
and will power down into Reset mode when VCC drops
