FEATURES
DESCRIPTION
■ 10 MHz SPI compatible
The CAT25C01/02/04 is a 1K/2K/4K Bit SPI Serial
CMOS EEPROM internally organized as 128x8/256x8/
512x8 bits. Catalyst’s advanced CMOS Technology
substantially reduces device power requirements. The
CAT25C01/02/04 features a 16-byte page write buffer.
The device operates via the SPI bus serial interface and
is enabled though a Chip Select (CS). In addition to the
Chip Select, the clock input (SCK), data in (SI) and data
out (SO) are required to access the device. The HOLD
pin may be used to suspend any serial communication
without resetting the serial sequence. The CAT25C01/
02/04 is designed with software and hardware write
protection features including Block Write protection. The
device is available in 8-pin DIP, 8-pin SOIC and 8-pin
TSSOP packages.

FUNCTIONAL DESCRIPTION
PIN DESCRIPTION
The CAT25C01/02/04 supports the SPI bus data
transmission protocol. The synchronous Serial Peripheral
Interface (SPI) helps the CAT25C01/02/04 to interface
directly with many of today’s popular microcontrollers.
The CAT25C01/02/04 contains an 8-bit instruction
register. (The instruction set and the operation codes
are detailed in the instruction 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
CAT25010/20/40. Input data is latched on the rising
edge of the serial clock for SPI modes (0, 0 & 1, 1).
SO: Serial Output
SO is the serial data output pin. This pin is used to
transfer data out of the CAT25C01/02/04. During a read
cycle, data is shifted out on the falling 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
the operation to be performed.

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 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. Figure 10 illustrates the WP timing
sequence during a write operation.
SCK: Serial Clock
SCK is the serial clock pin. This pin is used to synchronize
the communication between the microcontroller and the
CAT25C01/02/04. 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) .
CS
CS: Chip Select
CS is the Chip select pin. CS low enables the CAT25C01/
02/04 and CS high disables the CAT25C01/02/04. 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) The CAT25C01/
02/04 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.
HOLD

WP: Write Protect
WP is the Write Protect pin. The Write Protect pin will

The HOLD pin is used to pause transmission to the
CAT25C01/20/40 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.

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.
STATUS REGISTER
The Status Register indicates the status of the device.
The RDY (Ready) bit indicates whether the CAT25C01/
02/04 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
The BP0 and BP1 (Block Protect) bits indicate which
blocks are currently protected. These bits are set by the
user issuing the WRSR instruction. The user is allowed
to protect quarter of the memory, half of the memory or
the entire memory by setting these bits. Once protected,
the user may only read from the protected portion of the
array. These bits are non-volatile.

READ Sequence
The part is selected by pulling CS low. The 8-bit read
instruction is transmitted to the CAT25C01/02/04,
followed by the 8-bit address for CAT25C01/02/04 (for
the CAT25C04, bit 3 of the read data instruction contains
address A8).
The WPEN (Write Protect Enable) is an enable bit 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

Write Enable and Disable
The CAT25C01/02/04 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.

Write enable state by pulling the CS low and then
clocking the WREN instruction into CAT25C01/02/04.
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.
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.
The read operation is terminated by pulling the CS high.
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. Read sequece is
illustrated in Figure 4. Reading status register is illustrated
in Figure 5.
WRITE Sequence
The CAT25C01/02/04 powers up in a Write Disable
state. Prior to any write instructions, the WREN instruction
must be sent to CAT25C01/02/04. The device goes into

During an internal write cycle, all commands will be
ignored except the RDSR (Read Status Register)
instruction.
address will remain constant. The only restriction is that
the X (X=16 for CAT25C01/02/04) 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 CAT25C01/02/04
is automatically returned to the write disable state at the
completion of the write cycle. Figure 8 illustrates the
page write sequence.
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.
Page Write
The CAT25C01/02/04 features page write capability.
After the initial byte, the host may continue to write up to
16 bytes of data to the CAT25C01/02/04. After each
byte of data received, lower order address bits are
internally incremented by one; the high order bits of

DESIGN CONSIDERATIONS
ming 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 CAT25C01/02/04, and the serial
output pin (SO) will remain in a high impedance state
until the falling edge of CS is detected again.
The CAT25C01/02/04 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
CAT25C01/02/04 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 program-
When powering down, the supply should be taken down
to 0V, so that the CAT25C01/02/04 will be reset when
power is ramped back up. If this is not possible, then,
following a brown-out episode, the CAT25C01/02/04
can be reset by refreshing the contents of the Status
Register (See Application Note AN10).
