9-Mbit (256K × 36/512K × 18)
Pipelined SRAM with NoBL™ Architecture
9-Mbit (256K
× 36/512K × 18) Pipelined SRAM with NoBL™ Architecture
Features
Functional Description
■ Pin-compatible with and functionally equivalent to ZBT™
■ Supports 250 MHz bus operations with zero wait states
■ Available speed grades are 250, 200, and 166 MHz
The
CY7C1354CV25/CY7C1356CV25[1]
are
2.5 V,
256K × 36/512K × 18 synchronous pipelined burst SRAMs with
No Bus Latency™ (NoBL logic, respectively. They are
designed to support unlimited true back-to-back read/write
operations
with
no
wait
states.
The
■ Internally self-timed output buffer control to eliminate the need
to use asynchronous OE
CY7C1354CV25/CY7C1356CV25 are equipped with the
advanced (NoBL) logic required to enable consecutive
read/write operations with data being transferred on every clock
cycle. This feature dramatically improves the throughput of data
in systems that require frequent write/read transitions. The
CY7C1354CV25/CY7C1356CV25 are pin-compatible with and
functionally equivalent to ZBT devices.
■ Fully registered (inputs and outputs) for pipelined operation
■ Byte write capability
■ Single 2.5 V power supply (VDD
)
■ Fast clock-to-output times
❐ 2.8 ns (for 250-MHz device)
All synchronous inputs pass through input registers controlled by
the rising edge of the clock. All data outputs pass through output
registers controlled by the rising edge of the clock. The clock
input is qualified by the clock enable (CEN) signal, which when
deasserted suspends operation and extends the previous clock
cycle.
■ Clock enable (CEN) pin to suspend operation
■ Synchronous self-timed writes
■ Available in Pb-free 100-pin TQFP package, Pb-free and
non Pb-free 119-ball BGA package and 165-ball FBGA
package
Write operations are controlled by the byte write selects
(BWa–BWd for CY7C1354CV25 and BWa–BWb for
CY7C1356CV25) and a write enable (WE) input. All writes are
conducted with on-chip synchronous self-timed write circuitry.
■ IEEE 1149.1 JTAG-compatible boundary scan
■ Burst capability – linear or interleaved burst order
■ “ZZ” sleep mode option and stop clock option
Three synchronous chip enables (CE1, CE2, CE3) and an
asynchronous output enable (OE) provide for easy bank
selection and output tri-state control. In order to avoid bus
contention, the output drivers are synchronously tri-stated during
the data portion of a write sequence.

A0, A1, A
Input-
synchronous
Address inputs used to select one of the address locations. Sampled at the rising edge of the CLK.
BWa, BWb,
Input-
Byte write select inputs, active LOW. Qualified with WE to conduct writes to the SRAM. Sampled on
BWc, BWd synchronous the rising edge of CLK. BWa controls DQa and DQPa, BWb controls DQb and DQPb, BWc controls DQc
and DQPc, BWd controls DQd and DQPd.
WE
Input-
Write enable input, active LOW. Sampled on the rising edge of CLK if CEN is active LOW. This signal
synchronous must be asserted LOW to initiate a write sequence.
ADV/LD
Input- Advance/load input used to advance the on-chip address counter or load a new address. When
synchronous HIGH (and CEN is asserted LOW) the internal burst counter is advanced. When LOW, a new address
can be loaded into the device for an access. After being deselected, ADV/LD should be driven LOW in
order to load a new address.
CLK
CE1
CE2
CE3
OE
Input-
clock
Clock input. Used to capture all synchronous inputs to the device. CLK is qualified with CEN. CLK is
only recognized if CEN is active LOW.
Input-
Chip enable 1 input, active LOW. Sampled on the rising edge of CLK. Used in conjunction with CE2
synchronous and CE3 to select/deselect the device.
Input-
Chip enable 2 input, active HIGH. Sampled on the rising edge of CLK. Used in conjunction with CE1
synchronous and CE3 to select/deselect the device.
Input-
Chip enable 3 Input, active LOW. Sampled on the rising edge of CLK. Used in conjunction with CE1
synchronous and CE2 to select/deselect the device.
Input-
Output enable, active LOW. Combined with the synchronous logic block inside the device to control
asynchronous the direction of the I/O pins. When LOW, the I/O pins are allowed to behave as outputs. When deasserted
HIGH, I/O pins are tri-stated, and act as input data pins. OE is masked during the data portion of a write
sequence, during the first clock when emerging from a deselected state and when the device has been
deselected.
CEN
DQS
Input-
Clock enable input, active LOW. When asserted LOW the clock signal is recognized by the SRAM.
synchronous When deasserted HIGH the clock signal is masked. Since deasserting CEN does not deselect the device,
CEN can be used to extend the previous cycle when required.
I/O-
Bidirectional data I/O lines. As inputs, they feed into an on-chip data register that is triggered by the
synchronous rising edge of CLK. As outputs, they deliver the data contained in the memory location specified by
addresses during the previous clock rise of the read cycle. The direction of the pins is controlled by OE
and the internal control logic. When OE is asserted LOW, the pins can behave as outputs. When HIGH,
DQa–DQd are placed in a tri-state condition. The outputs are automatically tri-stated during the data
portion of a write sequence, during the first clock when emerging from a deselected state, and when the
device is deselected, regardless of the state of OE.
DQPX
MODE
TDO
TDI
I/O-
Bidirectional data parity I/O lines. Functionally, these signals are identical to DQ[a:d]. During write
synchronous sequences, DQPa is controlled by BWa, DQPb is controlled by BWb, DQPc is controlled by BWc, and
DQPd is controlled by BWd.
Input strap pin Mode input. Selects the burst order of the device. Tied HIGH selects the interleaved burst order. Pulled
LOW selects the linear burst order. MODE should not change states during operation. When left floating
MODE will default HIGH, to an interleaved burst order.
JTAG serial Serial data-out to the JTAG circuit. Delivers data on the negative edge of TCK.

Functional Overview
register and onto the data bus within 2.8 ns (250-MHz device)
provided OE is active LOW. After the first clock of the read
access the output buffers are controlled by OE and the internal
control logic. OE must be driven LOW in order for the device to
drive out the requested data. During the second clock, a
subsequent operation (read/write/deselect) can be initiated.
Deselecting the device is also pipelined. Therefore, when the
SRAM is deselected at clock rise by one of the chip enable
signals, its output will tri-state following the next clock rise.
The
CY7C1354CV25/CY7C1356CV25
are
synchronous-pipelined burst NoBL SRAMs designed specifically
to eliminate wait states during write/read transitions. All
synchronous inputs pass through input registers controlled by
the rising edge of the clock. The clock signal is qualified with the
clock enable input signal (CEN). If CEN is HIGH, the clock signal
is not recognized and all internal states are maintained. All
synchronous operations are qualified with CEN. All data outputs
pass through output registers controlled by the rising edge of the
clock. Maximum access delay from the clock rise (tCO) is 2.8 ns
(250-MHz device).
Burst Read Accesses
The CY7C1354CV25/CY7C1356CV25 have an on-chip burst
counter that allows the user the ability to supply a single address
and conduct up to four reads without reasserting the address
inputs. ADV/LD must be driven LOW in order to load a new
address into the SRAM, as described in Single Read Accesses.
The sequence of the burst counter is determined by the MODE
input signal. A LOW input on MODE selects a linear burst mode,
a HIGH selects an interleaved burst sequence. Both burst
counters use A0 and A1 in the burst sequence, and will wrap
around when incremented sufficiently. A HIGH input on ADV/LD
will increment the internal burst counter regardless of the state
of chip enables inputs or WE. WE is latched at the beginning of
a burst cycle. Therefore, the type of access (read or write) is
maintained throughout the burst sequence.
Accesses can be initiated by asserting all three chip enables
(CE1, CE2, CE3) active at the rising edge of the clock. If clock
enable (CEN) is active LOW and ADV/LD is asserted LOW, the
address presented to the device will be latched. The access can
either be a read or write operation, depending on the status of
the write enable (WE). BW[d:a] can be used to conduct byte write
operations.
Write operations are qualified by the write enable (WE). All writes
are simplified with on-chip synchronous self-timed write circuitry.
Three synchronous chip enables (CE1, CE2, CE3) and an
asynchronous output enable (OE) simplify depth expansion. All
operations (reads, writes, and deselects) are pipelined. ADV/LD
should be driven LOW once the device has been deselected in
order to load a new address for the next operation.
Single Write Accesses
Write access are initiated when the following conditions are
satisfied at clock rise: (1) CEN is asserted LOW, (2) CE1, CE2,
and CE3 are all asserted active, and (3) the write signal WE is
asserted LOW. The address presented to A0–A16 is loaded into
the address register. The write signals are latched into the
control logic block.
Single Read Accesses
A read access is initiated when the following conditions are
satisfied at clock rise: (1) CEN is asserted LOW, (2) CE1, CE2,
and CE3 are all asserted active, (3) the write enable input signal
WE is deasserted HIGH, and (4) ADV/LD is asserted LOW. The
address presented to the address inputs is latched into the
address register and presented to the memory core and control
logic. The control logic determines that a read access is in
progress and allows the requested data to propagate to the input
of the output register. At the rising edge of the next clock the
On the subsequent clock rise the data lines are automatically
tri-stated regardless of the state of the OE input signal. This
allows the external logic to present the data on DQ and DQP
(DQa,b,c,d/DQPa,b,c,d for CY7C1354CV25 and DQa,b/DQPa,b for

CY7C1354CV25
CY7C1356CV25
CY7C1356CV25). In addition, the address for the subsequent
access (read/write/deselect) is latched into the address register
(provided the appropriate control signals are asserted).
Sleep Mode
The ZZ input pin is an asynchronous input. Asserting ZZ places
the SRAM in a power conservation “sleep” mode. Two clock
cycles are required to enter into or exit from this “sleep” mode.
While in this mode, data integrity is guaranteed. Accesses
pending when entering the “sleep” mode are not considered valid
nor is the completion of the operation guaranteed. The device
must be deselected prior to entering the “sleep” mode. CE1, CE2,
and CE3, must remain inactive for the duration of tZZREC after the
ZZ input returns LOW.
On the next clock rise the data presented to DQ
(DQa,b,c,d/DQPa,b,c,d for CY7C1354CV25 and DQa,b/DQaPnda,bDfQoPr
CY7C1356CV25) (or a subset for byte write operations, see
Write Cycle Description table for details) inputs is latched into the
device and the Write is complete.
The data written during the write operation is controlled by BW
(BWa,b,c,d for CY7C1354CV25 and BWa,b for CY7C1356CV25)
signals. The CY7C1354CV25/CY7C1356CV25 provides byte
write capability that is described in the Write Cycle Description
table. Asserting the write enable input (WE) with the selected
byte write select (BW) input will selectively write to only the
desired bytes. Bytes not selected during a byte write operation

Because the CY7C1354CV25/CY7C1356CV25 are common I/O
devices, data should not be driven into the device while the
outputs are active. The output enable (OE) can be deasserted
HIGH before presenting data to the DQ and DQP
(DQa,b,c,d/DQPa,b,c,d for CY7C1354CV25 and DQa,b/DQPa,b for

As a safety precaution, DQ and DQP (DQa,b,c,d/DQPa,b,c,d for
CY7C1354CV25 and DQa,b/DQPa,b for CY7C1356CV25) are
automatically tri-stated during the data portion of a write cycle,
regardless of the state of OE.

The CY7C1354CV25/CY7C1356CV25 has an on-chip burst
counter that allows the user the ability to supply a single address
and conduct up to four write operations without reasserting the
address inputs. ADV/LD must be driven LOW in order to load the
initial address, as described in Single Write Accesses. When
ADV/LD is driven HIGH on the subsequent clock rise, the chip
enables (CE1, CE2, and CE3) and WE inputs are ignored and the
burst counter is incremented. The correct BW (BWa,b,c,d for
CY7C1354CV25 and BWa,b for CY7C1356CV25) inputs must be
driven in each cycle of the burst write in order to write the correct
bytes of data.

CY7C1354CV25
CY7C1356CV25
Performing a TAP Reset
IEEE 1149.1 Serial Boundary Scan (JTAG)
A RESET is performed by forcing TMS HIGH (VDD) for five rising
edges of TCK. This RESET does not affect the operation of the
SRAM and may be performed while the SRAM is operating.
The CY7C1354CV25/CY7C1356CV25 incorporates a serial
boundary scan test access port (TAP) in the BGA package only.
The TQFP package does not offer this functionality. This part
operates in accordance with IEEE Standard 1149.1-1900, but
doesn’t have the set of functions required for full 1149.1
compliance. These functions from the IEEE specification are
excluded because their inclusion places an added delay in the
critical speed path of the SRAM. Note the TAP controller
functions in a manner that does not conflict with the operation of
other devices using 1149.1 fully compliant TAPs. The TAP
operates using JEDEC-standard 2.5 V I/O logic levels.
At power-up, the TAP is reset internally to ensure that TDO
comes up in a high Z state.
TAP Registers
Registers are connected between the TDI and TDO balls and
allow data to be scanned into and out of the SRAM test circuitry.
Only one register can be selected at a time through the
instruction register. Data is serially loaded into the TDI ball on the
rising edge of TCK. Data is output on the TDO ball on the falling
edge of TCK.
The CY7C1354CV25/CY7C1356CV25 contains
a
TAP
controller, instruction register, boundary scan register, bypass
register, and ID register.
Instruction Register
Disabling the JTAG Feature
Three-bit instructions can be serially loaded into the instruction
register. This register is loaded when it is placed between the TDI
and TDO balls as shown in the TAP Controller Block Diagram on
page 16. Upon power-up, the instruction register is loaded with
the IDCODE instruction.
It is possible to operate the SRAM without using the JTAG
feature. To disable the TAP controller, TCK must be tied LOW
(VSS) to prevent clocking of the device. TDI and TMS are
internally pulled up and may be unconnected. They may
alternately be connected to VDD through a pull-up resistor. TDO
should be left unconnected. Upon power-up, the device will
come up in a reset state which will not interfere with the operation
of the device.
It is also loaded with the IDCODE instruction if the controller is
placed in a reset state as described in the previous section.
When the TAP controller is in the Capture-IR state, the two least
significant bits are loaded with a binary “01” pattern to allow for
fault isolation of the board-level serial test data path.
Test Access Port (TAP)
Bypass Register
Test Clock (TCK)
To save time when serially shifting data through registers, it is
sometimes advantageous to skip certain chips. The bypass
register is a single-bit register that can be placed between the
TDI and TDO balls. This allows data to be shifted through the
The test clock is used only with the TAP controller. All inputs are
captured on the rising edge of TCK. All outputs are driven from
the falling edge of TCK.
SRAM with minimal delay. The bypass register is set LOW (VSS
when the BYPASS instruction is executed.
)
Test Mode Select (TMS)
The TMS input is used to give commands to the TAP controller
and is sampled on the rising edge of TCK. It is allowable to leave
this ball unconnected if the TAP is not used.
Boundary Scan Register
The boundary scan register is connected to all the input and
bidirectional balls on the SRAM.
The ball is pulled up internally, resulting in a logic HIGH level.
The boundary scan register is loaded with the contents of the
RAM I/O ring when the TAP controller is in the Capture-DR state
and is then placed between the TDI and TDO balls when the
controller is moved to the Shift-DR state. The EXTEST,
SAMPLE/PRELOAD and SAMPLE Z instructions can be used to
capture the contents of the I/O ring.
Test Data-In (TDI)
The TDI ball is used to serially input information into the registers
and can be connected to the input of any of the registers. The
register between TDI and TDO is chosen by the instruction that
is loaded into the TAP instruction register. For information on
loading the instruction register, see TAP Controller State
Diagram on page 15. TDI is internally pulled up and can be
unconnected if the TAP is unused in an application. TDI is
connected to the most significant bit (MSB) of any register.
The Boundary Scan Exit Order on page 19 and Boundary Scan
Exit Order on page 20 show the order in which the bits are
connected. Each bit corresponds to one of the bumps on the
SRAM package. The MSB of the register is connected to TDI,
and the LSB is connected to TDO.
Test Data-Out (TDO)
The TDO output ball is used to serially clock data-out from the
registers. The output is active depending upon the current state
of the TAP state machine (see Instruction Codes on page 18).
The output changes on the falling edge of TCK. TDO is
connected to the least significant bit (LSB) of any register.
Identification (ID) Register
The ID register is loaded with a vendor-specific, 32-bit code
during the Capture-DR state when the IDCODE command is
loaded in the instruction register. The IDCODE is hardwired into
the SRAM and can be shifted out when the TAP controller is in
the Shift-DR state. The ID register has a vendor code and other
information described in the Identification Register Definitions on
page 18.
Document Number: 38-05537 Rev. *R
Page 13 of 35
CY7C1354CV25
CY7C1356CV25
during the Capture-DR state, an input or output will undergo a
transition. The TAP may then try to capture a signal while in
transition (metastable state). This will not harm the device, but
there is no guarantee as to the value that will be captured.
Repeatable results may not be possible.
TAP Instruction Set
Overview
Eight different instructions are possible with the three bit
instruction register. All combinations are listed in the Instruction
Codes table. Three of these instructions are listed as
RESERVED and should not be used. The other five instructions
are described in detail below.
To guarantee that the boundary scan register will capture the
correct value of a signal, the SRAM signal must be stabilized
long enough to meet the TAP controller’s capture set-up plus
hold times (tCS and tCH). The SRAM clock input might not be
captured correctly if there is no way in a design to stop (or slow)
the clock during a SAMPLE/PRELOAD instruction. If this is an
issue, it is still possible to capture all other signals and simply
ignore the value of the CK and CK# captured in the boundary
scan register.
Instructions are loaded into the TAP controller during the Shift-IR
state when the instruction register is placed between TDI and
TDO. During this state, instructions are shifted through the
instruction register through the TDI and TDO balls. To execute
the instruction once it is shifted in, the TAP controller needs to be
moved into the Update-IR state.
Once the data is captured, it is possible to shift out the data by
putting the TAP into the Shift-DR state. This places the boundary
scan register between the TDI and TDO pins.
IDCODE
The IDCODE instruction causes a vendor-specific, 32-bit code
to be loaded into the instruction register. It also places the
instruction register between the TDI and TDO balls and allows
the IDCODE to be shifted out of the device when the TAP
controller enters the Shift-DR state.
PRELOAD allows an initial data pattern to be placed at the
latched parallel outputs of the boundary scan register cells prior
to the selection of another boundary scan test operation.
The shifting of data for the SAMPLE and PRELOAD phases can
occur concurrently when required — that is, while data captured
is shifted out, the preloaded data can be shifted in.
The IDCODE instruction is loaded into the instruction register
upon power-up or whenever the TAP controller is given a test
logic reset state.
BYPASS
SAMPLE Z
When the BYPASS instruction is loaded in the instruction register
and the TAP is placed in a Shift-DR state, the bypass register is
placed between the TDI and TDO pins. The advantage of the
BYPASS instruction is that it shortens the boundary scan path
when multiple devices are connected together on a board.
The SAMPLE Z instruction causes the boundary scan register to
be connected between the TDI and TDO pins when the TAP
controller is in a Shift-DR state. The SAMPLE Z command puts
the output bus into a high Z state until the next command is given
during the “Update IR” state.
EXTEST
SAMPLE/PRELOAD
The EXTEST instruction enables the preloaded data to be driven
out through the system output pins. This instruction also selects
the boundary scan register to be connected for serial access
between the TDI and TDO in the shift-DR controller state.
SAMPLE/PRELOAD is a 1149.1 mandatory instruction. When
the SAMPLE/PRELOAD instructions are loaded into the
instruction register and the TAP controller is in the Capture-DR
state, a snapshot of data on the inputs and output pins is
captured in the boundary scan register.
Reserved
The user must be aware that the TAP controller clock can only
operate at a frequency up to 20 MHz, while the SRAM clock
operates more than an order of magnitude faster. Because there
is a large difference in the clock frequencies, it is possible that
These instructions are not implemented but are reserved for
future use. Do not use these instructions.
