PIN DESCRIPTION
FUNCTIONAL DESCRIPTION
The CAT25010/20/40 devices support 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 1.
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.
Reading data stored in the CAT25010/20/40 is accom–
plished by simply providing the READ command and an
address. Writing to the CAT25010/20/40, 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.
SCK: The serial clock input pin accepts the clock
provided by the host and used for synchronizing
communication between host and CAT25010/20/40.

CS: The chip select input pin is used to enable/disable

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 CAT25010/20/40 must be preceded by a high to

WRITE OPERATIONS
¯¯
The CAT25010/20/40 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.
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 2.
The WREN instruction must be sent prior any WRITE
or WRSR instruction.
The internal write enable latch is reset by sending the
WRDI instruction as shown in Figure 3. Disabling write
operations by resetting the WEL bit, will protect the
device against inadvertent writes.
Write Enable and Write Disable
The internal Write Enable Latch and the corresponding
Status Register WEL bit are set by sending the WREN
instruction to the CAT25010/20/40. Care must be taken

Page Write
Once the WEL bit is set, the user may execute a write

CAT25040, bit 3 of the write instruction opcode
contains A8 address bit. Internal programming will
After sending the first data byte to the
CAT25010/20/40, the host may continue sending
data, up to a total of 16 bytes, according to timing
shown in Figure 5. 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
previoualy loaded data. Following completion of the
write cycle, the CAT25010/20/40 is automatically
returned to the write disable state.

READ OPERATIONS
Read Status Register
Read from Memory Array
To read the status register, the host simply sends a
RDSR command. After receiving the last bit of the
command, the CAT25010/20/40 will shift out the
contents of the status register on the SO pin
(Figure 9). The status register may be read at any
time, including during an internal write cycle.
To read from memory, the host sends a READ
instruction followed by a 8-bit address (for the
CAT25040, bit 3 of the read instruction opcode
contains A8 address bit).
After receiving the last address bit, the
CAT25010/20/40 will respond by shifting out data on
the SO pin (as shown in Figure 8). 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.

Hold Operation
¯¯¯¯¯
The HOLD input can be used to pause communication
¯¯¯¯¯
between host and CAT25010/20/40. To pause, HOLD
must be taken low while SCK is low (Figure 10).
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 CAT25010/20/40 devices incorporate 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 below the POR trigger level.
This bi-directional POR behavior protects the device
against ‘brown-out’ failure following a temporary loss
of power.
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 CAT25010/20/40 device powers up in a write
disable state and in a low power standby mode. A
WREN instruction must be issued prior any writes to
the device.
