CAT25320
FUNCTIONAL DESCRIPTION
PIN DESCRIPTION
The CAT25320 supports the SPI bus data transmission
protocol. The synchronous Serial Peripheral Interface
(SPI) helps the CAT25320 to interface directly with
manyoftoday’spopularmicrocontrollers.TheCAT25320
contains an 8-bit instruction register. (The instruction
set andtheoperationcodesaredetailedintheinstruction
set table)
SI: Serial Input
SI is the serial data input pin. This pin is used to input all
opcodes, byte addresses, and data to be written to the
CAT25320.Inputdataislatchedontherisingedgeofthe
serial clock.
SO: Serial Output
SO is the serial data output pin. This pin is used to
transfer data out of the CAT25320. During a read cycle,
data is shifted out on the falling edge of the serial clock.
After the device is selected with CS going low, the first
byte will be received. The part is accessed via the SI pin,
with data being clocked in on the rising edge of SCK.
Thefirstbytecontainsoneofthesixop-codesthatdefine
the operation to be performed.

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.TheWPpinfunctionisblockedwhentheWPEN
bit is set to 0. Figure 10 illustrates the WP timing
sequence during a write operation.
CS: Chip Select
CS istheChipselectpin. CSlowenablestheCAT25320
and CS high disables the CAT25320. CS high takes the
SO output pin to high impedance and forces the devices
into a Standby Mode (unless an internal write operation
is underway). A high to low transition on CS is required
prior to any sequence being initiated. A low to high
transition on CS after a valid write sequence is what
initiates an internal write cycle.
HOLD: Hold
The HOLD pin is used to pause transmission to the
CAT25320 while in the middle of a serial sequence
without having to re-transmit entire sequence at a later
time. To pause, HOLD must be brought low while SCK
islow.TheSOpinisinahighimpedancestateduringthe

high, while SCK is low. (HOLD should be held high any
time this function is not being used.) HOLD may be tied
high directly to Vcc or tied to Vcc through a resistor.
Figure 9 illustrates hold timing sequence.
WP: Write Protect
WP is the Write Protect pin. The Write Protect pin will
allow normal read/write operations when held high.
When WP is tied low and the WPEN bit in the status
register is set to “1”, all write operations to the status
register are inhibited. WP going low while CS is still low

CAT25320
The WPEN (Write Protect Enable) is an enable bit for the
WP pin. The WP pin and WPEN bit in the status register
controltheprogrammablehardwarewriteprotectfeature.
HardwarewriteprotectionisenabledwhenWPis lowand
WPENbitissettohigh.Theusercannotwritetothestatus
register (including the block protect bits and the WPEN
bit) and the block protected sections in the memory array
when the chip is hardware write protected. Only the
sections of the memory array that are not block protected
can be written. Hardware write protection is disabled
when either WP pin is high or the WPEN bit is zero.
STATUS REGISTER
The Status Register indicates the status of the device.
The RDY (Ready) bit indicates whether the CAT25320
is busy with a write operation. When set to 1 a write
cycle is in progress and when set to 0 the device
indicates it is ready. This bit is read only.
The WEL (Write Enable) bit indicates the status of the
write enable latch . 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 WEL bit can only be set by the
WREN instruction and can be reset by the WRDI
instruction.
DEVICE OPERATION
Write Enable and Disable
The BP0 and BP1 (Block Protect) bits indicate which
blocksarecurrentlyprotected. Thesebitsaresetbythe
user issuing the WRSR instruction. The user is allowed
to protect quarter of the memory, half of the memory or
theentirememorybysettingthesebits. Onceprotected
the user may only read from the protected portion of the
array. These bits are non-volatile.
The CAT25320 contains a write enable latch. This latch
must be set before any write operation. The device
powers up in a write disable state when Vcc is applied.
WREN instruction will enable writes (set the latch) to
thedevice. WRDI instruction will disable writes (reset the
latch) to the device. Disabling writes will protect the
device against inadvertent writes.

CAT25320
READ Sequence
To read the status register, RDSR instruction should be
sent. The contents of the status register are shifted out
on the SO line. The status register may be read at any
time even during a write cycle. Reading status register
is illustrated in Figure 5.
The part is selected by pulling CS low. The 8-bit read
instruction is transmitted to the CAT25320, followed by
the16-bitaddress(thefourmostsignificantbitsaredon't
care).
WRITE Sequence
After the correct read instruction and address are sent,
the data stored in the memory at the selected address is
shifted out on the SO pin. The data stored in the memory
at the next address can be read sequentially by continu-
ing to provide clock pulses. The internal address pointer
is automatically incremented to the next higher address
after each byte of data is shifted out. When the highest
address, FFFh is reached, the address counter rolls
over to 0000h allowing the read cycle to be continued
indefinitely. The read operation is terminated by pulling
the CS high. Read sequece is illustrated in Figure 4.
The CAT25320 powers up in a Write Disable state. Prior
to any write instructions, the WREN instruction must be
sent to CAT25320. The device goes into Write enable
state by pulling the CS low and then clocking the WREN
instruction into CAT25320. The CS must be brought
high after the WREN instruction to enable writes to the
device. If the write operation is initiated immediately
after the WREN instruction without CS being brought
high, the data will not be written to the array because the
write enable latch will not have been properly set. Also,
for a successful write operation the address of the
memory location(s) to be programmed must be outside
the protected address field location selected by the
block protection level.

CAT25320
Byte Write
address will remain constant. The only restriction is that the
64 bytes must reside on the same page. If the address
counter reaches the end of the page and clock continues,
the counter will “roll over” to the first address of the page
and overwrite any data that may have been written. The
CAT25320 is automatically returned to the write disable
state at the completion of the write cycle. Figure 8 illustrates
the page write sequence.
Once the device is in a Write Enable state, the user
may proceed with a write sequence by setting the CS
low, issuing a write instruction via the SI line, followed
by the 16-bit address (four most significant bits are
don't care), and then the data to be written. Program-
ming will start after the CS is brought high. Figure 6
illustrates byte write sequence.
During an internal write cycle, all commands will be
ignored except the RDSR (Read Status Register)
instruction.
Status Register Write
To write to the status register, the WRSR instruction should
be sent. Only Bit 2, Bit 3 and Bit 7 of the status register can
be written using the WRSR instruction. Figure 7 illustrates
the sequence of writing to status register.
The Status Register can be read to determine if the
write cycle is still in progress. If Bit 0 of the Status
Register is set at 1, write cycle is in progress. If Bit 0
is set at 0, the device is ready for the next instruction.
DESIGN CONSIDERATIONS
The CAT25320 powers up in a write disable state and in a
low power standby mode. A WREN instruction must be
issued to perform any writes to the device after power up.
After power up CS must be brought low to enter a ready
state and receive an instruction. After a successful byte/
page write or status register write the CAT25320 goes into
Page Write
The CAT25320 features page write capability. After
the first initial byte the host may continue to write up
to 64 bytes of data to the CAT25320. After each byte
of data is received, six lower order address bits are
internally incremented by one; the high order bits of
