CY7C1161V18, CY7C1176V18  
CY7C1163V18, CY7C1165V18  
18-Mbit QDR™-II+ SRAM 4-Word Burst  
Architecture (2.5 Cycle Read Latency)  
Features  
Functional Description  
Separate independent read and write data ports  
Supports concurrent transactions  
The CY7C1161V18, CY7C1176V18, CY7C1163V18, and  
CY7C1165V18 are 1.8V Synchronous Pipelined SRAMs  
equipped with QDR™-II+ architecture. QDR-II+ architecture  
consists of two separate ports to access the memory array. The  
read port has dedicated data outputs to support read operations  
and the write port has dedicated data inputs to support write  
300 MHz to 400 MHz clock for high bandwidth  
4-word burst to reduce address bus frequency  
DoubleDataRate(DDR)interfacesonbothreadandwriteports  
(data transferred at 800 MHz) at 400 MHz  
operations. QDR-II+ architecture has separate data inputs and  
data outputs to completely eliminate the need to turn around the  
data bus that is required with common IO devices. Each port can  
be accessed through a common address bus. Addresses for  
read and write addresses are latched onto alternate rising edges  
of the input (K) clock. Accesses to the QDR-II+ read and write  
ports are completely independent of one another. In order to  
maximize data throughput, both read and write ports are  
equipped with Double Data Rate (DDR) interfaces. Each  
address location is associated with four 8-bit words  
(CY7C1161V18), 9-bit words (CY7C1176V18), 18-bit words  
(CY7C1163V18), or 36-bit words (CY7C1165V18) that burst  
sequentially into or out of the device. Because data can be trans-  
ferred into and out of the device on every rising edge of both input  
clocks K and K, memory bandwidth is maximized while simpli-  
fying system design by eliminating bus turnarounds.  
Read latency of 2.5 clock cycles  
Two input clocks (K and K) for precise DDR timing  
SRAM uses rising edges only  
Echo clocks (CQ and CQ) simplify data capture in high speed  
systems  
Single multiplexed address input bus latches address inputs  
for both read and write ports  
Separate port selects for depth expansion  
Data valid pin (QVLD) to indicate valid data on the output  
Synchronous internally self-timed writes  
Available in x8, x9, x18, and x36 configurations  
Depth expansion is accomplished with port selects for each port.  
Port selects allow each port to operate independently.  
Full data coherency providing most current data  
All synchronous inputs pass through input registers controlled by  
the K or K input clocks. All data outputs pass through output  
registers controlled by the or K or K input clocks. Writes are  
conducted with on-chip synchronous self-timed write circuitry.  
Core V = 1.8V ± 0.1V; IO V  
= 1.4V to V

nected.  
DOFF  
DLL Turn Off Active LOW. Connecting this pin to ground turns off the DLL inside the device. The  
timings in the DLL turned-off operation are different from those listed in this data sheet. For normal  
operation, this pin is connected to a pull up through a 10 KΩ or less pull up resistor. The device  
behaves in QDR-I mode when the DLL is turned off. In this mode, the device operates at a frequency  
of up to 167 MHz with QDR-I timing.

CY7C1163V18, CY7C1165V18  
Write Operations  
Functional Overview  
Write operations are initiated by asserting WPS active at the  
rising edge of the positive input clock (K). On the following K  
The CY7C1161V18, CY7C1176V18, CY7C1163V18, and  
CY7C1165V18 are synchronous pipelined burst SRAMs  
equipped with both a read port and a write port. The read port is  
dedicated to read operations and the write port is dedicated to  
write operations. Data flows into the SRAM through the write port  
and out through the read port. These devices multiplex the  
address inputs in order to minimize the number of address pins  
required. By having separate read and write ports, the QDR-II+  
completely eliminates the need to “turn-around” the data bus. It  
avoids any possible data contention, thereby, simplifying system  
design. Each access consists of four 8-bit data transfers in the  
case of CY7C1161V18, four 9-bit data transfers in the case of  
CY7C1176V18, four 18-bit data transfers in the case of  
CY7C1163V18, and four 36-bit data transfers in the case of  
CY7C1165V18 in two clock cycles.

input clock (K), the information presented to D is also stored

are both asserted  
into the write data register, provided BWS

active. This process continues for one more cycle until four 18-bit  
words (a total of 72 bits) of data are stored in the SRAM. The 72  
bits of data are then written into the memory array at the specified  
location. Therefore, write accesses to the device cannot be  
initiated on two consecutive K clock rises. The internal logic of  
the device ignores the second write request. Write accesses are  
initiated on every other rising edge of the positive input clock (K).  
Doing so pipelines the data flow such that 18 bits of data can be  
transferred into the device on every rising edge of the input  
clocks (K and K).  
Accesses for both ports are initiated on the positive input clock  
(K). All synchronous input and output timings are referenced to  
the rising edge of the Input clocks (K/K).  
When deselected, the write port ignores all inputs after the  
pending write operations are completed.

Byte write operations are supported by the CY7C1163V18. A  
write operation is initiated as described in the Write Operations  
section above. The bytes that are written are determined by  
BWS and BWS , which are sampled with each set of 18-bit data  
rising edge of the Input clocks (K and K) also.

words. Asserting the appropriate byte write select input during  
the data portion of a write enables the data being presented to  
be latched and written into the device. Deasserting the byte write  
select input during the data portion of a write allows the data  
stored in the device for that byte to remain unaltered. This feature  
is used to simplify read, modify, and write operations to a byte  
write operation.  
CY7C1163V18 is described in the following sections. The same  
basic descriptions apply to CY7C1161V18, CY7C1176V18, and  
CY7C1165V18.  
Read Operations  
The CY7C1163V18 is organized internally as four arrays of 256K  
x 18. Accesses are completed in a burst of four sequential 18-bit  
data words. Read operations are initiated by asserting RPS  
active at the rising edge of the positive input clock (K). The  
address presented to address inputs are stored in the Read  
address register. Following the next two K clock rises, the corre-  
sponding lowest order 18-bit word of data is driven onto the  
Concurrent Transactions  
The read and write ports on the CY7C1163V18 operate  
completely independent of one another. Because each port  
latches the address inputs on different clock edges, the user can  
read or write to any location, regardless of the transaction on the  
other port. If the ports access the same location when a read  
follows a write in successive clock cycles, the SRAM delivers the  
most recent information associated with the specified address  
location. This includes forwarding data from a write cycle initiated  
on the previous K clock rise.  
Q
using K as the output timing reference. On the subse-  
[17:0]  
quent rising edge of K, the next 18-bit data word is driven onto  
the Q . This process continues until all four 18-bit data words  
[17:0]  
have been driven out onto Q  
. The requested data is valid  
[17:0]  
0.45 ns from the rising edge of the Input clock K or K. In order to  
maintain the internal logic, each read access must be allowed to  
complete. Each read access consists of four 18-bit data words  
and takes two clock cycles to complete. Therefore, read  
accesses to the device cannot be initiated on two consecutive K  
clock rises. The internal logic of the device ignores the second  
read request. Read accesses can be initiated on every other K  
clock rise. Doing so pipelines the data flow such that data is  
transferred out of the device on every rising edge of the input  
clocks K and K.  
Read accesses and write access are scheduled such that one  
transaction is initiated on any clock cycle. If both ports are  
selected on the same K clock rise, the arbitration depends on the  
previous state of the SRAM. If both ports are deselected, the  
read port takes priority. If a read is initiated on the previous cycle,  
the write port assumes priority (because read operations cannot  
be initiated on consecutive cycles). If a write was initiated on the  
previous cycle, the read port assumes priority (because write  
operations cannot be initiated on consecutive cycles). Therefore,  
asserting both port selects active from a deselected state results  
in alternating read or write operations initiated, with the first  
access being a read.  
When the read port is deselected, the CY7C1163V18 first  
completes the pending read transactions. Synchronous internal  
circuitry automatically tri-states the outputs following the next  
rising edge of the negative input clock (K). This allows for a  
seamless transition between devices without the insertion of wait  
states in a depth expanded memory.

Depth Expansion  
Valid Data Indicator (QVLD)  
The CY7C1163V18 has a port select input for each port. This  
enables easy depth expansion. Both port selects are only  
sampled on the rising edge of the positive input clock (K). Each  
port select input can deselect the specified port. Deselecting a  
port does not affect the other port. All pending transactions (read  
and write) are completed before the device is deselected.  
QVLD is provided on the QDR-II+ to simplify data capture on high  
speed systems. The QVLD is generated by the QDR-II+ device  
along with data output. This signal is also edge-aligned with the  
echo clock and follows the timing of any data pin. This signal is  
asserted half a cycle before valid data arrives.  
DLL  
Programmable Impedance  
These chips utilize a Delay Lock Loop (DLL) that is designed to  
function between 120 MHz and the specified maximum clock  
erations in QDRII/DDRII/QDRII+/DDRII+.” The DLL can also be  
reset by slowing or stopping the input clocks K and K for a  
minimum of 30 ns. However, it is not necessary for the DLL to be  
reset in order to lock to the desired frequency. During power up  
when the DOFF is tied HIGH, the DLL is locked after 2048 cycles  
of stable clock.  
An external resistor, RQ, must be connected between the ZQ pin  
on the SRAM and V to enable the SRAM to adjust its output  
SS  
driver impedance. The value of RQ must be 5X the value of the  
intended line impedance driven by the SRAM. The allowable  
range of RQ to guarantee impedance matching with a tolerance  
of ±15% is between 175Ω and 350Ω, with V  
= 1.5V. The  
DDQ  
output impedance is adjusted every 1024 cycles upon power up  
to account for drifts in supply voltage and temperature.  
Echo Clocks  
Echo clocks are provided on the QDR-II+ to simplify data capture  
on high speed systems. Two echo clocks are generated by the  
QDR-II+. CQ is referenced with respect to K and CQ is refer-  
enced with respect to K. These are free running clocks and are  
synchronized to the input clock of the QDR-II+. The timings for  
the echo clocks are shown in the AC timing table.

2. The above application shows four QDR-II+ being used.  
3. X = “Don't Care,” H = Logic HIGH, L = Logic LOW, represents rising edge.  
4. Device powers up deselected and the outputs in a tri-state condition.  
5. “A” represents address location latched by the devices when transaction was initiated. A + 1, A + 2, and A + 3 represents the address sequence in the burst.  
6. “t” represents the cycle at which a read or write operation is started. t + 1, t + 2, t + 3 and t + 4 are the first, second, third, and fourth clock cycles, respectively succeeding  
the “t” clock cycle.  
7. Data inputs are registered at K and K rising edges. Data outputs are delivered on K and K rising edges.  
8. It is recommended that K = K = HIGH when clock is stopped. This is not essential, but permits most rapid restart by overcoming transmission line charging symmetrically.  
9. If this signal was LOW to initiate the previous cycle, this signal becomes a “Don’t Care” for this operation.  
10. This signal was HIGH on previous K clock rise. Initiating consecutive read or write operations on consecutive K clock rises is not permitted. The device ignores the  
second read or write request.

CY7C1161V18, CY7C1176V18  
CY7C1163V18, CY7C1165V18  
Instruction Register  
IEEE 1149.1 Serial Boundary Scan (JTAG)  
Three-bit instructions are serially loaded into the instruction  
register. This register is loaded when it is placed between the TDI  
page 16. 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.  
These SRAMs incorporate a serial boundary scan test access  
port (TAP) in the FBGA package. This part is fully compliant with  
IEEE Standard 1149.1-2001. The TAP operates using JEDEC  
standard 1.8V IO logic levels.  
Disabling the JTAG Feature  
It is possible to operate the SRAM without using the JTAG  
feature. To disable the TAP controller, TCK must be tied LOW  
When the TAP controller is in the Capture IR state, the two least  
significant bits are loaded with a binary “01” pattern to allow fault  
isolation of the board level serial test path.  
(V ) to prevent clocking of the device. TDI and TMS are inter-  
SS  
nally pulled up and may be unconnected. They may alternatively  
be connected to V through a pull up resistor. TDO must be left  
unconnected. Upon power up, the device comes up in a reset  
state which does not interfere with the operation of the device.  
Bypass Register  
DD  
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 TDI  
and TDO pins. This enables data to be shifted through the SRAM  
with minimal delay. The bypass register is set LOW (V ) when  
the BYPASS instruction is executed.  
Test Access Port—Test Clock  
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.  
SS  
Boundary Scan Register  
Test Mode Select  
The boundary scan register is connected to all of the input and  
output pins on the SRAM. Several no connect (NC) pins are also  
included in the scan register to reserve pins for higher density  
devices.  
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 pin unconnected if the TAP is not used. The pin is pulled up  
internally, resulting in a logic HIGH level.  
The boundary scan register is loaded with the contents of the  
RAM Input and Output ring when the TAP controller is in the  
Capture-DR state and is then placed between the TDI and TDO  
pins 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 Input and Output ring.  
Test Data In (TDI)  
The TDI pin 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) on any register.  
The “Boundary Scan Order” on page 19 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.  
Identification (ID) Register  
Test Data Out (TDO)  
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  
The TDO output pin 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.  
Performing a TAP Reset  
A Reset is performed by forcing TMS HIGH (V ) for five rising  
TAP Instruction Set  
DD  
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.  
Eight different instructions are possible with the three-bit  
instruction register. All combinations are listed in the “Instruction  
Codes” on page 18. Three of these instructions are listed as  
RESERVED and must not be used. The other five instructions  
are described below.  
TAP Registers  
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 pins. To execute  
the instruction once it is shifted in, the TAP controller needs to be  
moved into the Update-IR state.  
Registers are connected between the TDI and TDO pins and  
enables data to be scanned into and out of the SRAM test  
circuitry. Only one register is selected at a time through the  
instruction registers. Data is serially loaded into the TDI pin on  
the rising edge of TCK. Data outputs on the TDO pin on the falling  
edge of TCK.

CY7C1163V18, CY7C1165V18  
IDCODE  
PRELOAD enables an initial data pattern to be placed at the  
latched parallel outputs of the boundary scan register cells  
before the selection of another boundary scan test operation.  
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 pins and enables  
the IDCODE to be shifted out of the device when the TAP  
controller enters the Shift-DR state. 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 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 is shifted in.  
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.  
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.  
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.  
SAMPLE/PRELOAD  
SAMPLE/PRELOAD is a 1149.1 mandatory instruction. When  
the SAMPLE/PRELOAD instructions are loaded into the instruc-  
tion 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.  
EXTEST OUTPUT BUS TRI-STATE  
IEEE Standard 1149.1 mandates that the TAP controller puts the  
output bus into a tri-state mode.  
The user must be aware that the TAP controller clock only oper-  
ates at a frequency up to 20 MHz, while the SRAM clock oper-  
ates 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 undergoes a transition.  
The TAP then tries to capture a signal while in transition (meta-  
stable state). This does not harm the device but there is no guar-  
antee as to the value that is captured. Repeatable results are not  
possible.  
The boundary scan register has a special bit located at bit 47.  
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 directly controls the state of the output  
(Q-bus) pins, when the EXTEST is entered as the current  
instruction. When HIGH, it enables the output buffers to drive the  
output bus. When LOW, this bit places the output bus into a High  
Z condition.  
To guarantee that the boundary scan register captures the cor-  
rect value of a signal, the SRAM signal is stabilized long enough  
This bit is 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 loaded into that  
shift register cell latches into the preload register. When the  
EXTEST instruction is entered, this bit directly controls 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.  
to meet the TAP controller's capture setup plus hold times (t  
CS  
and t ). The SRAM clock input is not captured correctly if there  
CH  
is no way in a design to stop (or slow) the clock during a SAM-  
PLE/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.  
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.

Power Up Sequence in QDR-II+ SRA  
DLL Constraints  
During power up, when the DOFF is tied HIGH, the DLL gets  
locked after 2048 cycles of stable clock. QDR-II+ SRAMs must  
be powered up and initialized in a predefined manner to prevent  
undefined operations.  
DLL uses K clock as its synchronizing input. The input must  
have low phase jitter, which is specified as t  
KC Var  
The DLL functions at frequencies down to 120 MHz  
If the input clock is unstable and the DLL is enabled, then the  
DLL locks onto an incorrect frequency, causing unstable SRAM  
behavior. To avoid this, provide 2048 cycles stable clock to  
relock to the desired clock frequency

Notes  
24. When a part with a maximum frequency above 300 MHz is operating at a lower clock frequency, it requires the input timings of the frequency range in which it is being  
operated and outputs data with the output timings of that frequency range.  
25. This part has a voltage regulator internally; t  
is the time that the power needs to be supplied above V minimum initially before a Read or Write operation can  
POWER  
DD  
be initiated.  
26. These parameters are extrapolated from the input timing parameters (t  
– 250 ps, where 250 ps is the internal jitter. An input jitter of 200 ps (t  
) is already  
KHKH  
KC Var  
included in the t  
). These parameters are only guaranteed by design and are not tested in production.

31. Q00 refers to output from address A0. Q01 refers to output from the next internal burst address following A0, i.e., A0+1.  
32. Outputs are disabled (High Z) one clock cycle after a NOP.  
33. In this example, if address A2 = A1, then data Q20 = D10 and Q21 = D11. Write data is forwarded immediately as read results. This note applies to the whole diagram.
