CY7C1327C/GVT71256DA18
256K x 18/128K x 36 Synchronous-Pipelined
Cache RAM
The CY7C1347C/GVT71128DA36 and CYC7C1327C/
GVT71256DA18 SRAMs integrate 131,072x36 and
262,144x18 SRAM cells with advanced synchronous periph-
Features
• Fast access times: 2.5 and 3.5 ns
eral circuitry and a 2-bit counter for internal burst operation. All
synchronous inputs are gated by registers controlled by a pos-
itive-edge-triggered clock input (CLK). The synchronous in-
puts include all addresses, all data inputs, address-pipelining
Chip Enable (CE), depth-expansion Chip Enables (CE2 and
CE2), Burst Control Inputs (ADSC, ADSP, and ADV), Write
Enables (BWa, BWb, BWc, BWd, and BWE), and Global Write
(GW).
• Fast clock speed: 250, 225, 200, and 166 MHz
• 1-ns set-up time and hold time
• Fast OE access times: 2.5 ns and 3.5 ns
• Optimal for depth expansion (one cycle chip deselect
to eliminate bus contention)
• 3.3V –5% and +10% power supply
• 3.3V or 2.5V I/O supply
• 5V tolerant inputs except I/Os
Asynchronous inputs include the Output Enable (OE) and
Burst Mode Control (MODE). The data outputs (Q), enabled
by OE, are also asynchronous.
• Clamp diodes to V at all inputs and outputs
SS
• Common data inputs and data outputs
Addresses and chip enables are registered with either Ad-
dress Status Processor (ADSP) or Address Status Controller
(ADSC) input pins. Subsequent burst addresses can be inter-
nally generated as controlled by the Burst Advance pin (ADV).
• Byte Write Enable and Global Write control
• Three chip enables for depth expansion and address
pipeline
• Address, data, and control registers
• Internally self-timed Write Cycle
• Burst control pins (interleaved or linear burst se-
quence)
• Automatic power-down for portable applications
• JTAG boundary scan
• JEDEC standard pinout
• Low profile 119-lead, 14-mm x 22-mm BGA (Ball Grid
Array) and 100-pin TQFP packages
Address, data inputs, and write controls are registered on-chip
to initiate self-timed Write cycle. Write cycles can be one to
four bytes wide as controlled by the write control inputs. Indi-
vidual byte write allows individual byte to be written. BWa con-
trols DQa. BWb controls DQb. BWc controls DQc. BWd con-
trols DQd. BWa, BWb, BWc, and BWd can be active only with
BWE being LOW. GW being LOW causes all bytes to be writ-
ten. The x18 version only has 18 data inputs/outputs (DQa and
DQb) along with BWa and BWb (no BWc, BWd, DQc, and
DQd).
Functional Description
Four pins are used to implement JTAG test capabilities: Test
Mode Select (TMS), Test Data-in (TDI), Test Clock (TCK), and
Test Data-out (TDO). The JTAG circuitry is used to serially shift
data to and from the device. JTAG inputs use LVTTL/LVCMOS
levels to shift data during this testing mode of operation.
The Cypress Synchronous Burst SRAM family employs
high-speed, low-power CMOS designs using advanced tri-
ple-layer polysilicon, double-layer metal technology. Each
memory cell consists of four transistors and two high-valued
resistors.
The
CY7C1347C/GVT71128DA36
and
CY7C1327C/
GVT71256DA18 operate from a +3.3V power supply. All inputs
and outputs are LVTTL compatible

Note:
2. X means “don’t care.” H means logic HIGH. L means logic LOW.
For X36 product, WRITE = L means [BWE + BWa*BWb*BWc*BWd]*GW equals LOW. WRITE = H means [BWE + BWa*BWb*BWc*BWd]*GW equals HIGH.
For X18 product, WRITE = L means [BWE + BWa*BWb]*GW equals LOW. WRITE = H means [BWE + BWa*BWb]*GW equals HIGH.
3. BWa enables write to DQa. BWb enables write to DQb. BWc enables write to DQc. BWd enables write to DQd.
4. All inputs except OE must meet set-up and hold times around the rising edge (LOW to HIGH) of CLK.
5. Suspending burst generates wait cycle.
6. For a write operation following a read operation, OE must be HIGH before the input data required set-up time plus High-Z time for OE and staying HIGH
throughout the input data hold time.
7. This device contains circuitry that will ensure the outputs will be in High-Z during power-up.
8. ADSP LOW along with chip being selected always initiates a READ cycle at the L-H edge of CLK. A WRITE cycle can be performed by setting WRITE LOW
for the CLK L-H edge of the subsequent wait cycle. Refer to WRITE timing diagram for clarification.
9. For X18 product, there are only BWa and BWb.

Performing a TAP Reset
IEEE 1149.1 Serial Boundary Scan (JTAG)
The TAP circuitry does not have a reset pin (TRST, which is
optional in the IEEE 1149.1 specification). A RESET can be
Overview
This device incorporates a serial boundary scan access port
(TAP). This port is designed to operate in a manner consistent
with IEEE Standard 1149.1-1990 (commonly referred to as
JTAG), but does not implement all of the functions required for
IEEE 1149.1 compliance. Certain functions have been modi-
fied or eliminated because their implementation places extra
delays in the critical speed path of the device. Nevertheless,
the device supports the standard TAP controller architecture
(the TAP controller is the state machine that controls the TAPs
operation) and can be expected to function in a manner that
does not conflict with the operation of devices with IEEE Stan-
dard 1149.1 compliant TAPs. The TAP operates using
LVTTL/LVCMOS logic level signaling.

for five rising edges of TCK and pre-loads the instruction reg-
ister with the IDCODE command. This type of reset does not
affect the operation of the system logic. The reset affects test
logic only.
At power-up, the TAP is reset internally to ensure that TDO is
in a High-Z state.
Test Access Port (TAP) Registers
Overview
The various TAP registers are selected (one at a time) via the
sequences of ones and zeros input to the TMS pin as the TCK
is strobed. Each of the TAPs registers are serial shift registers
that capture serial input data on the rising edge of TCK and
push serial data out on subsequent falling edge of TCK. When
a register is selected, it is connected between the TDI and
TDO pins.
Disabling the JTAG Feature
It is possible to use this device without using the JTAG feature.
To disable the TAP controller without interfering with normal
operation of the device, TCK should be tied LOW (V ) to pre-
SS
vent clocking the device. TDI and TMS are internally pulled up
and may be unconnected. They may alternately be pulled up
to VCC through a 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.
Instruction Register
The instruction register holds the instructions that are execut-
ed by the TAP controller when it is moved into the run test/idle
or the various data register states. The instructions are three
bits long. The register can be loaded when it is placed between
the TDI and TDO pins. The parallel outputs of the instruction
register are automatically preloaded with the IDCODE instruc-
tion upon power-up or whenever the controller is placed in the
test-logic reset state. When the TAP controller is in the Cap-
ture-IR state, the two least significant bits of the serial instruc-
tion register are loaded with a binary “01” pattern to allow for
fault isolation of the board-level serial test data path.
Test Access Port (TAP)
TCK - Test Clock (INPUT)
Clocks all TAP events. All inputs are captured on the rising
edge of TCK and all outputs propagate from the falling edge of
TCK.
TMS - Test Mode Select (INPUT)
The TMS input is sampled on the rising edge of TCK. This is
the command input for the TAP controller state machine. It is
allowable to leave this pin unconnected if the TAP is not used.
The pin is pulled up internally, resulting in a logic HIGH level.
Bypass Register
The bypass register is a single-bit register that can be placed
between TDI and TDO. It allows serial test data to be passed
through the device TAP to another device in the scan chain
with minimum delay. The bypass register is set LOW (V
when the BYPASS instruction is executed.
)
SS
TDI - Test Data In (INPUT)
The TDI input is sampled on the rising edge of TCK. This is the
input side of the serial registers placed between TDI and TDO.
The register placed between TDI and TDO is determined by
the state of the TAP controller state machine and the instruc-
tion that is currently loaded in the TAP instruction register (refer
to Figure 1, TAP Controller State Diagram). It is allowable to
leave this pin unconnected if it is not used in an application.
The pin is pulled up internally, resulting in a logic HIGH level.
TDI is connected to the most significant bit (MSB) of any reg-
ister. (See Figure 2.)
Boundary Scan Register
The Boundary scan register is connected to all the input and
bidirectional I/O pins (not counting the TAP pins) on the device.
This also includes a number of NC pins that are reserved for
future needs. There are a total of 70 bits for x36 device and 51
bits for x18 device. The boundary scan register, under the con-
trol of the TAP controller, is loaded with the contents of the
device I/O ring when the controller is in Capture-DR state and
then is placed between the TDI and TDO pins when the con-
troller is moved to Shift-DR state. The EXTEST, SAMPLE/
PRELOAD and SAMPLE-Z instructions can be used to cap-
ture the contents of the I/O ring.
TDO - Test Data Out (OUTPUT)
The TDO output pin is used to serially clock data-out from the
registers. The output that is active depending on the state of
the TAP state machine (refer to Figure 1, TAP Controller State
Diagram). Output changes in response to the falling edge of
TCK. This is the output side of the serial registers placed be-
tween TDI and TDO. TDO is connected to the least significant
bit (LSB) of any register. (See Figure 2.)
The Boundary Scan Order table describes the order in which
the bits are connected. The first column defines the bit’s posi-
tion in the boundary scan register. The MSB of the register is
connected to TDI, and LSB is connected to TDO. The second
column is the signal name and the third column is the bump
number. The third column is the TQFP pin number and the
fourth column is the BGA bump number.

Identification (ID) Register
ture-DR mode and places the ID register between the TDI and
TDO pins in Shift-DR mode. The IDCODE instruction is the
default instruction loaded in the instruction upon power-up and
at any time the TAP controller is placed in the test-logic reset
state.
The ID Register is a 32-bit register that is loaded with a device
and vendor specific 32-bit code when the controller is put in
Capture-DR state with the IDCODE command loaded in the
instruction register. The register is then placed between the
TDI and TDO pins when the controller is moved into Shift-DR
state. Bit 0 in the register is the LSB and the first to reach TDO
when shifting begins. The code is loaded from a 32-bit on-chip
ROM. It describes various attributes of the device as described
in the Identification Register Definitions table.
SAMPLE-Z
If the High-Z instruction is loaded in the instruction register, all
output pins are forced to a High-Z state and the boundary scan
register is connected between TDI and TDO pins when the
TAP controller is in a Shift-DR state.
TAP Controller Instruction Set
SAMPLE/PRELOAD
Overview
SAMPLE/PRELOAD is an IEEE 1149.1 mandatory instruction.
The PRELOAD portion of the command is not implemented in
this device, so the device TAP controller is not fully IEEE
1149.1-compliant.
There are two classes of instructions defined in the IEEE Stan-
dard 1149.1-1990; the standard (public) instructions and de-
vice specific (private) instructions. Some public instructions
are mandatory for IEEE 1149.1 compliance. Optional public
instructions must be implemented in prescribed ways.
When the SAMPLE/PRELOAD instruction is loaded in the in-
struction register and the TAP controller is in the Capture-DR
state, a snap shot of the data in the device’s input and I/O
buffers is loaded into the boundary scan register. Because the
device system clock(s) are independent from the TAP clock
(TCK), it is possible for the TAP to attempt to capture the input
and I/O ring contents while the buffers are in transition (i.e., in
a metastable state). Although allowing the TAP to sample
metastable inputs will not harm the device, repeatable results
can not be expected. To guarantee that the boundary scan
register will capture the correct value of a signal, the device
input signals must be stabilized long enough to meet the TAP
Although the TAP controller in this device follows the IEEE
1149.1 conventions, it is not IEEE 1149.1 compliant because
some of the mandatory instructions are not fully implemented.
The TAP on this device may be used to monitor all input and
I/O pads, but can not be used to load address, data, or control
signals into the device or to preload the I/O buffers. In other
words, the device will not perform IEEE 1149.1 EXTEST, IN-
TEST, or the preload portion of the SAMPLE/PRELOAD com-
mand.
When the TAP controller is placed in Capture-IR state, the two
least significant bits of the instruction register are loaded with
01. When the controller is moved to the Shift-IR state the in-
struction is serially loaded through the TDI input (while the
previous contents are shifted out at TDO). For all instructions,
the TAP executes newly loaded instructions only when the con-
troller is moved to Update-IR state. The TAP instruction sets
for this device are listed in the following tables.
controller’s capture setup plus hold time (t
plus t ). The
CS
CH
device clock input(s) need not be paused for any other TAP
operation except capturing the input and I/O ring contents into
the boundary scan register.
Moving the controller to Shift-DR state then places the bound-
ary scan register between the TDI and TDO pins. Because the
PRELOAD portion of the command is not implemented in this
device, moving the controller to the Update-DR state with the
SAMPLE/PRELOAD instruction loaded in the instruction reg-
ister has the same effect as the Pause-DR command.
EXTEST
EXTEST is an IEEE 1149.1 mandatory public instruction. It is
to be executed whenever the instruction register is loaded with
all 0s. EXTEST is not implemented in this device.
BYPASS
When the BYPASS instruction is loaded in the instruction reg-
ister and the TAP controller is in the Shift-DR state, the bypass
register is placed between TDI and TDO. This allows the board
level scan path to be shortened to facilitate testing of other
devices in the scan path.
The TAP controller does recognize an all-0 instruction. When
an EXTEST instruction is loaded into the instruction register,
the device responds as if a SAMPLE/PRELOAD instruction
has been loaded. There is one difference between two instruc-
tions. Unlike SAMPLE/PRELOAD instruction, EXTEST places
the device outputs in a High-Z state.
Reserved
Do not use these instructions. They are reserved for future
use.
IDCODE
The IDCODE instruction causes a vendor-specific, 32-bit code
to be loaded into the ID register when the controller is in Cap-

Notes:
23. Test conditions as specified with the output loading as shown in part (a) of AC Test Loads unless otherwise noted.
24. At any given temperature and voltage condition, tKQHZ is less than tKQLZ and tOEHZ is less than tOELZ
.
25. OE is a “don’t care” when a byte write enable is sampled LOW.
26. This is a synchronous device. All synchronous inputs must meet specified set-up and hold time, except for “don’t care” as defined in the truth table.
