CY7C1370D  
CY7C1372D  
18-Mbit (512 K × 36/1 M × 18) Pipelined  
SRAM with NoBL™ Architecture  
18-Mbit (512  
K × 36/1 M × 18) Pipelined SRAM with NoBL™ Architecture  
Features  
Functional Description  
The CY7C1370D and CY7C1372D are 3.3 V, 512 K × 36 and  
Pin-compatible and functionally equivalent to ZBT™  
1 M × 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 CY7C1370D and CY7C1372D 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  
CY7C1370D and CY7C1372D are pin compatible and  
functionally equivalent to ZBT devices.  
Supports 250-MHz bus operations with zero wait states  
Available speed grades are 250, 200, and 167 MHz  
Internally self-timed output buffer control to eliminate the need  
to use asynchronous OE  
Fully registered (inputs and outputs) for pipelined operation  
Byte write capability  
3.3 V core power supply (VDD  
)
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.  
3.3 V/2.5 V I/O power supply (VDDQ  
)
Fast clock-to-output times  
2.6 ns (for 250 MHz device)  
Clock enable (CEN) pin to suspend operation  
Synchronous self-timed writes  
Write operations are controlled by the byte write selects  
(BWa–BWd for CY7C1370D and BWa–BWb for CY7C1372D)  
and a write enable (WE) input. All writes are conducted with  
on-chip synchronous self-timed write circuitry.  
Available in JEDEC-standard Pb-free 100-pin TQFP, Pb-free  
and non Pb-free 65-ball FBGA package  
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 tristated during  
the data portion of 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

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 tristated, 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 A[17:0]  
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 tristate condition. The outputs are automatically tristated 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  
I/O-  
Bidirectional data parity I/O lines. Functionally, these signals are identical to DQs. 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.  
MODE  
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.

CY7C1370D  
CY7C1372D  
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.  
Functional Overview  
The CY7C1370D and CY7C1372D 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 2.6 ns (250-MHz device).  
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 is loaded into the  
address register. The write signals are latched into the control  
logic block.  
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). BWX can be used to conduct byte write  
operations.  
On the subsequent clock rise the data lines are automatically  
tristated 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 CY7C1370D and DQa,b/DQPa,b for  
CY7C1372D). In addition, the address for the subsequent  
access (read/write/deselect) is latched into the address register  
(provided the appropriate control signals are asserted).  
Write operations are qualified by the write enable (WE). All writes  
are simplified with on-chip synchronous self-timed write circuitry.  
On the next clock rise the data presented to DQ and DQP  
(DQa,b,c,d/DQPa,b,c,d for CY7C1370D & DQa,b/DQPa,b for  
CY7C1372D) (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.  
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.  
The data written during the write operation is controlled by BW  
(BWa,b,c,d for CY7C1370D and BWa,b for CY7C1372D) signals.  
The CY7C1370D/CY7C1372D 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 will remain unaltered. A  
synchronous self-timed write mechanism has been provided to  
simplify the write operations. Byte write capability has been  
included in order to greatly simplify read/modify/write  
sequences, which can be reduced to simple byte write  
operations.  
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  
requested data is allowed to propagate through the output  
register and onto the data bus within 2.6 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 tristate following the next clock rise.  
Because the CY7C1370D and CY7C1372D 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 CY7C1370D and DQa,b/DQPa,b for  
CY7C1372D) inputs. Doing so will tri-state the output drivers. As  
a safety precaution, DQ and DQP (DQa,b,c,d/DQPa,b,c,d for  
CY7C1370D and DQa,b/DQPa,b for CY7C1372D) are  
automatically tristated during the data portion of a write cycle,  
regardless of the state of OE.  
Burst Write Accesses  
Burst Read Accesses  
The CY7C1370D/CY7C1372D 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 the Single Write Accesses section  
above. 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 CY7C1370D and BWa,b for CY7C1372D) inputs  
must be driven in each cycle of the burst write in order to write  
the correct bytes of data.  
The CY7C1370D and CY7C1372D 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 the Single Read  
Accesses section above. 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

Sleep Mode  
Linear Burst Address Table  
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.

CY7C1370D  
CY7C1372D  
IEEE 1149.1 Serial Boundary Scan (JTAG [17]  
)
At power-up, the TAP is reset internally to ensure that TDO  
comes up in a High Z state.  
The CY7C1370D incorporates a serial boundary scan test  
access port (TAP). This part is fully compliant with 1149.1. The  
TAP operates using JEDEC-standard 3.3 V or 2.5 V I/O logic  
levels.  
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 CY7C1370D contains a TAP controller, instruction register,  
boundary scan register, bypass register, and ID register.  
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  
(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.  
Instruction Register  
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 15. 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 0/1 next to each state represents the value of TMS at the  
rising edge of TCK.  
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.  
Test Mode Select (TMS)  
SRAM with minimal delay. The bypass register is set LOW (VSS  
)
when the BYPASS instruction is executed.  
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.  
Boundary Scan Register  
The boundary scan register is connected to all the input and  
bidirectional balls on the SRAM.  
Test Data-In (TDI)  
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.  
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 significant bit (MSB) of  
any register.  
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.  
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. 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  
table.  
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.  
Note  
17. Errata: The JTAG testing should be performed with these devices in BYPASS mode as the JTAG functionality is not guaranteed. For more information, see “Errata”

CY7C1370D  
CY7C1372D  
there is no guarantee as to the value that will be captured.  
Repeatable results may not be possible.  
TAP Instruction Set  
Overview  
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 setup 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.  
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.  
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.  
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.  
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.  
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.  
BYPASS  
IDCODE  
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 balls. The advantage of the  
BYPASS instruction is that it shortens the boundary scan path  
when multiple devices are connected together on a board.  
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.  
The IDCODE instruction is loaded into the instruction register  
upon power-up or whenever the TAP controller is given a test  
logic reset state.  
EXTEST Output Bus Tristate  
IEEE Standard 1149.1 mandates that the TAP controller be able  
to put the output bus into a tristate mode.  
SAMPLE Z  
The boundary scan register has a special bit located at bit #85  
(for 119-ball BGA package) or bit #89 (for 165-ball FBGA  
package). When this scan cell, called the “extest output bus  
tristate,” 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.  
The SAMPLE Z instruction causes the boundary scan register to  
be connected between the TDI and TDO balls when the TAP  
controller is in a Shift-DR state. It also places all SRAM outputs  
into a High Z state.  
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.  
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  
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.  
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  
Reserved  
These instructions are not implemented but are reserved for  
future use. Do not use these instructions.

Issues  
Description  
Device  
Fix Status  
1. ZZ Pin  
When asserted HIGH, the ZZ pin places  
deviceinasleepconditionwithdataintegrity  
preserved.The ZZ pin currently does not have  
an internal pull-down resistor and hence  
cannot be left floating externally by the user  
during normal mode of operation.  
18M-Ram9 (90nm)  
For the 18M Ram9 (90 nm)  
devices, there is no plan to fix  
this issue.  
2. JTAG  
During JTAG test mode, the Boundary scan  
18M-Ram9 (90nm)  
This issue will be fixed in the  
new revision, which use the  
65 nm technology. Please  
contact your local sales rep for  
availability.  
Functionality circuitry does not perform as described in the  
datasheet.However, it is possible to perform  
the JTAG test with these devices in “BYPASS  
mode”.

1. ZZ Pin Issue  
PROBLEM DEFINITION  
The problem occurs only when the device is operated in the normal mode with ZZ pin left floating. The ZZ pin on the SRAM  
device does not have an internal pull-down resistor. Switching noise in the system may cause the SRAM to recognize a HIGH  
on the ZZ input, which may cause the SRAM to enter sleep mode. This could result in incorrect or undesirable operation of the  
SRAM.  
TRIGGER CONDITIONS  
Device operated with ZZ pin left floating.  
SCOPE OF IMPACT  
When the ZZ pin is left floating, the device delivers incorrect data.  
WORKAROUND  
Tie the ZZ pin externally to ground.  
FIX STATUS  
For the 18M Ram9 (90 nm) devices, there is no plan to fix this issue.  
2. JTAG Functionality  
PROBLEM DEFINITION  
The problem occurs only when the device is operated in the JTAG test mode.During this mode, the JTAG circuitry can perform  
incorrectly by delivering the incorrect data or the incorrect scan chain length.  
TRIGGER CONDITIONS  
Several conditions can trigger this failure mode.  
1. The device can deliver an incorrect length scan chain when operating in JTAG mode.  
2. Some Byte Write inputs only recognize a logic HIGH level when in JTAG mode.  
3. Incorrect JTAG data can be read from the device when the ZZ input is tied HIGH during JTAG operation.  
SCOPE OF IMPACT  
The device fails for JTAG test. This does not impact the normal functionality of the device.  
WORKAROUND  
1.Perform JTAG testing with these devices in “BYPASS mode”.  
2.Do not use JTAG test.  
FIX STATUS  
This issue will be fixed in the new revision, which use the 65 nm technology. Please contact your local sales rep for availability
