DESCRIPTION
The CAT25C128/256 is a 128K/256K-Bit SPI Serial
CMOS EEPROM internally organized as 16Kx8/32Kx8
bits. Catalyst’s advanced CMOS Technology
substantially reduces device power requirements. The
CAT25C128/256 features a 64-byte page write buffer.
The device operates via the SPI bus serial interface
and is enabled through 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 CAT25C128/256 is designed with software and
hardware write protection features including Block Lock
protection. The device is available in 8-pin DIP, 8-pin
SOIC, 14-pin TSSOP and 20-pin TSSOP packages.

CAT25C128/256
SO: Serial Output
SO is the serial data output pin. This pin is used to transfer
data out of the CAT25C128/256. During a read cycle, data
is shifted out on the falling edge of the serial clock.
FUNCTIONAL DESCRIPTION
The CAT25C128/256 supports the SPI bus data
transmission protocol. The synchronous Serial Peripheral
Interface (SPI) helps the CAT25C128/256 to interface
directly with many of today’s popular microcontrollers.
The CAT25C128/256 contains an 8-bit instruction
register. (The instruction set and the operation codes
are detailed in the instruction set table)
SCK: Serial Clock
SCK is the serial clock pin. This pin is used to synchronize
the communication between the microcontroller and the
CAT25C128/256. 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.
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.
CS
CS: Chip Select
CS is the Chip select pin. CS low enables the CAT25C128/
256 and CS high disables the CAT25C128/256. 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 CAT25C128/256 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.
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
25C32/64. Input data is latched on the rising edge of the
serial clock.

CAT25C128/256
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 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.
9 illustrates hold timing sequence.
STATUS REGISTER
The Status Register indicates the status of the device.
The RDY (Ready) bit indicates whether the CAT25C128/
256 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
The HOLD pin is used to pause transmission to the
CAT25C128/256 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
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.

CAT25C128/256
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
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.
latch) to the device. Disabling writes will protect the
device against inadvertent writes.
READ Sequence
The part is selected by pulling CS low. The 8-bit read
instruction is transmitted to the CAT25C128/256, followed
by the 16-bit address(the three Most Significant Bit is
don’t care for 25C256 and four most significant bits are
don't care for 25C128).
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 (7FFFh for 25C256 and 3FFFh for 25C128) is
reached, the address counter rolls over to 0000h allowing
the read cycle to be continued indefinitely. The
readoperation is terminated by pulling the CS high.
DEVICE OPERATION
Write Enable and Disable
The CAT25C128/256 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

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.
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 CAT25C128/256 powers up in a Write Disable
state. Prior to any write instructions, the WREN instruction must be sent to CAT25C128/256. The device goes
into Write enable state by pulling the CS low and then
clocking the WREN instruction into CAT25C128/256.
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
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 (the three Most Significant Bits are don’t
care for 25C256 and four most significant bits are don't
care for 25C128), and then the data to be written.
Programming 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.

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 CAT25C128/256 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 CAT25C128/256 features page write capability.
After the first initial byte the host may continue to write
up to 64 bytes of data to the CAT25C128/256. After
each byte of data is received, six lower order address
bits are internally incremented by one; the high order
bits of address will remain constant. The only restriction
is that the 64 bytes must reside on the same page. If the
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.

CAT25C128/256
DESIGN CONSIDERATIONS
The CAT25C128/256 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
CAT25C128/256 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-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 CAT25C128/256, and the serial output pin (SO)
will remain in a high impedence state until the falling
edge of CS is detected again.
When powering down, the supply should be taken down
to 0V, so that the CAT25C128/256 will be reset when
power is ramped back up. If this is not possible, then,
following a brown-out episode, the CAT25C128/256
can be reset by refreshing the contents of the Status
Register (See Application Note AN10).
