CY7C1464AV33
36-Mbit (1M x 36/2M x 18/512K x 72)
Pipelined SRAM with NoBL™ Architecture
Functional Description
Features
• Pin-compatible and functionally equivalent to ZBT™
• Supports 250-MHz bus operations with zero wait states
— Available speed grades are 250, 200 and 167 MHz
The CY7C1460AV33/CY7C1462AV33/CY7C1464AV33 are
3.3V, 1M x 36/2M x 18/512K x72 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
CY7C1460AV33/CY7C1462AV33/CY7C1464AV33
are
equipped with the advanced (NoBL) logic required to enable
consecutive Read/Write operations with data being trans-
ferred on every clock cycle. This feature dramatically improves
the throughput of data in systems that require frequent
• Fully registered (inputs and outputs) for pipelined
operation
• Byte Write capability
Write/Read
transitions.
The
• 3.3V power supply
CY7C1460AV33/CY7C1462AV33/CY7C1464AV33 are pin
compatible and functionally equivalent to ZBT devices.
• 3.3V/2.5V I/O power supply
• Fast clock-to-output times
— 2.6 ns (for 250-MHz device)
• Clock Enable (CEN) pin to suspend operation
• Synchronous self-timed writes
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.

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.

Functional Overview
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.
The CY7C1460AV33/CY7C1462AV33/CY7C1464AV33 are
synchronous-pipelined Burst NoBL SRAMs designed specifi-
cally 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
Single Write Accesses
Write access are initiated when the following conditions are
satisfied at clock rise: (1) CEN is asserted LOW, (2) CE , CE ,
1
2
and CE are ALL asserted active, and (3) the write signal WE
3
is asserted LOW. The address presented to the address inputs
is loaded into the Address Register. The write signals are
latched into the Control Logic block.
(t ) is 2.6 ns (250-MHz device).
CO
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
Accesses can be initiated by asserting all three Chip Enables
(CE , CE , CE ) 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

clock of the read access the output buffers are controlled by
OE and the internal control logic. OE must be driven LOW in

Test Data-In (TDI)
IEEE 1149.1 Serial Boundary Scan (JTAG)
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. TDI
is internally pulled up and can be unconnected if the TAP is
unused in an application. TDI is connected to the most signif-
icant bit (MSB) of any register. (See Tap Controller Block
Diagram.)
The CY7C1460AV33/CY7C1462AV33/CY7C1464AV33 incor-
porates a serial boundary scan test access port (TAP). This
part is fully compliant with 1149.1. The TAP operates using
JEDEC-standard 3.3V or 2.5V I/O logic level.
The
CY7C1460AV33/CY7C1462AV33/CY7C1464AV33
contains a TAP controller, instruction register, boundary scan
register, bypass register, and ID register.
Disabling the JTAG Feature
Test Data-Out (TDO)
It is possible to operate the SRAM without using the JTAG
feature. To disable the TAP controller, TCK must be tied LOW
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. The output changes on the
falling edge of TCK. TDO is connected to the least significant
bit (LSB) of any register. (See Tap Controller State Diagram.)

Performing a TAP Reset
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.

At power-up, the TAP is reset internally to ensure that TDO
comes up in a High-Z state.
The 0/1 next to each state represents the value of TMS at the
rising edge of TCK.
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.
Test Access Port (TAP)
Test Clock (TCK)
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.
Instruction Register
Test MODE SELECT (TMS)
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. Upon power-up, the instruction register is loaded
with the IDCODE instruction. It is also loaded with the IDCODE
instruction if the controller is placed in a reset state as
described in the previous section.
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. The ball is
pulled up internally, resulting in a logic HIGH level.

CY7C1460AV33
CY7C1462AV33
CY7C1464AV33
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.
SAMPLE Z
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.
Bypass Register
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
SRAM with minimal delay. The bypass register is set LOW
SAMPLE/PRELOAD
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.
(V ) when the BYPASS instruction is executed.
SS
Boundary Scan Register
The boundary scan register is connected to all the input and
bidirectional balls on the SRAM. The length of the Boundary
Scan Register for the SRAM in different packages is listed in
the Scan Register Sizes table.
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 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.
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.
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
The Boundary Scan Order tables 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.

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.
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 table.
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.
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.
TAP Instruction Set
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.
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 instruc-
tions are described in detail below.
BYPASS
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.
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.
EXTEST
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.
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.
EXTEST OUTPUT BUS TRI-STATE
IEEE Standard 1149.1 mandates that the TAP controller be
able to put the output bus into a tri-state mode.
The IDCODE instruction is loaded into the instruction register
upon power-up or whenever the TAP controller is given a test
logic reset state.
The boundary scan register has a special bit located at bit #89
(for 165-FBGA package) or bit #138 (for 209-FBGA package).

When this scan cell, called the “extest output bus tri-state,” is
latched into the preload register during the “Update-DR” state
in the TAP controller, it will directly control the state of the
output (Q-bus) pins, when the EXTEST is entered as the
current instruction. When HIGH, it will enable the output
buffers to drive the output bus. When LOW, this bit will place
the output bus into a High-Z condition.
loaded into that shift-register cell will latch into the preload
register. When the EXTEST instruction is entered, this bit will
directly control the output Q-bus pins. Note that this bit is
preset HIGH to enable the output when the device is
powered-up, and also when the TAP controller is in the
“Test-Logic-Reset” state.
Reserved
This bit can be set by entering the SAMPLE/PRELOAD or
EXTEST command, and then shifting the desired bit into that
cell, during the “Shift-DR” state. During “Update-DR,” the value
