Description  
The CAT25320 is a 32−Kb Serial CMOS EEPROM device  
internally organized as 4096x8 bits. This features a 32−byte page write  
buffer and supports the Serial Peripheral Interface (SPI) protocol. The  
device is enabled through a Chip Select (CS) input. In addition, the  
required bus signals are clock input (SCK), data input (SI) and data  
output (SO) lines. The HOLD input may be used to pause any serial  
communication with the CAT25320 device. The device features  
software and hardware write protection, including partial as well as  
full array protection.

CAT25320  
Pin Description  
pausing, the HOLD input should be tied to V , either  
CC  
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.  
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.  
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.  
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.  
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.

CAT25320  
Status Register  
The Status Register, as shown in Table 8, contains a  
number of status and control bits.  
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 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 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 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.

CAT25320  
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.

CAT25320  
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).  
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.  
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.

CAT25320  
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
