FUNCTIONAL DESCRIPTION
the operation to be performed.
The CAT25C11/03/05/09/17 supports the SPI bus data
transmission protocol. The synchronous Serial Peripheral Interface (SPI) helps the CAT25C11/03/05/09/17 to
interface directly with many of today’s popular
microcontrollers. The CAT25C11/03/05/09/17 contains
an 8-bit instruction register. (The instruction set and the
operation codes are detailed in the instruction set table)
PIN DESCRIPTION
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
25C11/03/05/09/17.Input data is latched on the rising
edge of the serial clock for SPI modes (0, 0 & 1, 1).
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.
The first byte contains one of the six op-codes that define
SO: Serial Output
SO is the serial data output pin. This pin is used to transfer
data out of the 25C11/03/05/09/17. During a read cycle,
data is shifted out on the falling edge of the serial clock for

and forces the devices into a Standby Mode (unless an
internal write operation is underway) The CAT25C11/03/
05/09/17 draws ZERO current in the Standby mode. 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.
SPI modes (0,0 & 1,1).
SCK: Serial Clock
SCK is the serial clock pin. This pin is used to synchronize
the communication between the microcontroller and the
25C11/03/05/09/17. Opcodes, byte addresses, or data
present on the SI pin are latched on the rising edge of the
SCK. Data on the SO pin is updated on the falling edge of
the SCK for SPI modes (0,0 & 1,1).
WP
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 will interrupt a write to the
status register. If the internal write cycle as already been
initiated, WP going low will have no effect on any write
CS
CS: Chip Select
CS is the Chip select pin. CS low enables the CAT25C11/
03/05/09/17 and CS high disables the CAT25C11/03/05/
09/17. CS high takes the SO output pin to high impedance

operation to the status register. The WP pin function is
blocked when the WPEN bit is set to 0. Figure 10 illustrates
the WP timing sequence during a write operation.
03/05/09/17 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.
HOLD
HOLD: Hold
HOLD is the HOLD pin. The HOLD pin is used to pause
transmission to the CAT25C11/03/05/09/17 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 is low. The SO pin is in a high
impedance state during the time the part is paused, and
transitions on the SI pins will be ignored. To resume
communication, HOLD is brought 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.
The BP0, BP1 and BP2 bits indicate which part of the
memory array is currently protected. These bits are set
by the user issuing the WRSR instruction. The user is
allowed to protect from one page to as much as half the
entire array. Once the three protection bits are set the
associated memory can be read but not written until the
protection bits are reset. These bits are non volatile.
The WPEN (Write Protect Enable) is an enable b it for the
WP pin. The WP pin and WPEN bit in the status register
control the programmable hardware write protect feature. Hardware write protection is enabled when WP is
low and WPEN bit is set to high. The user cannot write
to the status 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.
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 continuing
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 is reached, the address counter rolls over to
0000h allowing the read cycle to be continued indefinitely.
DEVICE OPERATION
Write Enable and Disable
The CAT25C11/03/05/09/17 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 the device. WRDI instruction will disable writes
(reset the latch) to the device. Disabling writes will
protect the device against inadvertent writes.
The read operation is terminated by pulling the CS high.
Read sequece is illustrated in Figure 4. Reading status
register is illustrated in Figure 5. To read the status
register, RDSR instruction should be sent. The contents
of the status register are shifted out on the SO line. If a
non-volatile write is in progress, the RDSR instruction
returns a high on SO. When the non-volatile write cycle
is completed, the status register data is read out.
READ Sequence
The part is selected by pulling CS low. The 8-bit read
instruction is transmitted to the CAT25C11/03/05/09/17,
followed by the 16-bit address for 25C09/17 (only 10-bit
addresses are used for 25C09, 11-bit addresses are
used for 25C17. The rest of the bits are don't care bits)
and 8-bit address for 25C11/03/05 (for the 25C05, bit 3
of the read data instruction contains address A8).
WRITE Sequence
The CAT25C11/03/05/09/17 powers up in a Write Disable state. Prior to any write instructions, the WREN
instruction must be sent to CAT25C11/03/05/09/17.
The device goes into Write enable state by pulling the
CS low and then clocking the WREN instruction into
CAT25C11/03/05/09/17. The CS must be brought high

successful write operation the address of the memory
location(s) to be programmed must be outside the protected address field.
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
up to 16 bytes of data to the CAT25C11/03/05 and 32
bytes of data for 25C09/17. After each byte of data
received, lower order address bits are internally
incremented by one; the high order bits of address
willremain constant.The only restriction is that the X
(X=16 for 25C11/03/05 and X=32 for 25C09/17) 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
CAT25C11/03/05/09/17 is automatically returned to the
write disable state at the completion of the write cycle.
Figure 8 illustrates the page write sequence.
Byte Write
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 for 25C09/17. (only 10-bit addresses are
used for 25C09, 11-bit addresses are used for 25C17.
The rest of the bits are don't care bits) and 8-bit address
for 25C11/03/05 (for the 25C05, bit 3 of the read data
instruction contains address A8). Programming will start
after the CS is brought high. Figure 6 illustrates byte write
sequence.
To write to the status register, the WRSR instruction
should be sent. Only Bit 2, Bit 3, Bit 4 and Bit 7 of the
status register can be written using the write status
register instruction. Figure 7 illustrates the sequence of
writing to status register.
Page Write
The CAT25C11/03/05/09/17 features page write capability. After the initial byte, the host may continue to write
after the WREN instruction to enable writes to thee

CAT25C11/03/05/09/17
DESIGN CONSIDERATIONS
The CAT25C11/03/05/09/17 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. Also,on power up CS should be
brought low to enter a ready state and receive an
instruction. After a successful byte/page write or status
register write the CAT25C11/03/05/09/17 goes into a
write disable mode. CS must be set high after the proper
number of clock cycles to start an internal write cycle.
Access to the array during an internal write cycle is
ignored and programming is continued. On power up,
SO is in a high impedance. If an invalid op code is
received, no data will be shifted into the CAT25C11/03/
05/09/17, and the serial output pin (SO) will remain in a
high impedance state until the falling edge of CS is
detected again.
When powering down, the supply should be taken down
to 0V, so that the CAT25C11/03/05/09/17 will be reset
when power is ramped back up. If this is not possible,
then, following a brown-out episode, the CAT25C11/
03/05/09/17 can be reset by refreshing the contents of
the Status Register (See Application Note AN10).
