9Mb, FLOW THROUGH 'NO WAIT'
STATE BUS SRAM
AUGUST 2005
FEATURES
DESCRIPTION
The 9 Meg 'NLF/NVF' product family feature high-speed,
low-power synchronous static RAMs designed to provide
a burstable, high-performance, 'no wait' state, device for
networking and communications applications. They are
organized as 256K words by 36 bits and 512K words by 18
bits, fabricated with ISSI's advanced CMOS technology.
• 100 percent bus utilization
• No wait cycles between Read and Write
• Internal self-timed write cycle
• Individual Byte Write Control
• Single Read/Write control pin
Incorporating a 'no wait' state feature, wait cycles are
eliminated when the bus switches from read to write, or
write to read. This device integrates a 2-bit burst counter,
high-speed SRAM core, and high-drive capability outputs
into a single monolithic circuit.
• Clock controlled, registered address,
data and control
• Interleaved or linear burst sequence control using
MODE input
Allsynchronousinputspassthroughregistersarecontrolled
byapositive-edge-triggeredsingleclockinput.Operations
may be suspended and all synchronous inputs ignored
when Clock Enable, CKE is HIGH. In this state the internal
device will hold their previous values.
• Three chip enables for simple depth expansion
and address pipelining
• Power Down mode
• Common data inputs and data outputs
• CKE pin to enable clock and suspend operation
All Read, Write and Deselect cycles are initiated by the
ADV input. When the ADV is HIGH the internal burst
counter is incremented. New external addresses can be
loaded when ADV is LOW.
• JEDEC 100-pin TQFP, 119-ball PBGA, and 165-
ball PBGA packages
Write cycles are internally self-timed and are initiated by
the rising edge of the clock inputs and when WE is LOW.
Separate byte enables allow individual bytes to be written.
• Power supply:
NVF: VDD 2.5V (± 5%), VDDQ 2.5V (± 5%)
NLF: VDD 3.3V (± 5%), VDDQ 3.3V/2.5V (± 5%)
A burst mode pin (MODE) defines the order of the burst
sequence.WhentiedHIGH,theinterleavedburstsequence
is selected. When tied LOW, the linear burst sequence is
selected.
• JTAG Boundary Scan for PBGA packages
• Industrial temperature available
• Lead-free available

IEEE1149.1SERIALBOUNDARYSCAN(JTAG)
TEST ACCESS PORT (TAP) - TEST CLOCK
TheIS61NLFXand IS61NVFXhaveaserialboundaryscan
Test Access Port (TAP) in the PBGA package only. (Not
available in TQFP package.) This port operates in accor-
dance with IEEE Standard 1149.1-1900, but does not
include all functions required for full 1149.1 compliance.
These functions from the IEEE specification are excluded
because they place added delay in the critical speed path
oftheSRAM.TheTAPcontrolleroperatesinamannerthat
does not conflict with the performance of other devices
using1149.1fullycompliantTAPs.TheTAPoperatesusing
JEDEC standard 2.5V I/O logic levels.
The test clock is only used with the TAP controller. All
inputs are captured on the rising edge of TCK and outputs
are driven from the falling edge of TCK.
TEST MODE SELECT (TMS)
The TMS input is used to send commands to the TAP
controller and is sampled on the rising edge of TCK. This
pin may be left disconnected if the TAP is not used. The
pin is internally pulled up, resulting in a logic HIGH level.
TEST DATA-IN (TDI)
The TDI pin is used to serially input information to the
registers and can be connected to the input of any
register. The register between TDI and TDO is chosen by
the instruction loaded into the TAP instruction register.
For information on instruction register loading, see the
TAP Controller State Diagram. TDI is internally pulled up
and can be disconnected if the TAP is unused in an
application. TDI is connected to the Most Significant Bit
(MSB) on any register.
DISABLING THE JTAG FEATURE
TheSRAMcanoperatewithoutusingtheJTAGfeature.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 disconnected. They may alternately
beconnectedtoVDD throughapull-upresistor.TDOshould
beleftdisconnected. Onpower-up, thedevicewillstartina

TEST DATA OUT (TDO)
The TDO output pin is used to serially clock data-out from
theregisters.Theoutputisactivedependingonthecurrent
state of the TAP state machine (see TAP Controller State
Diagram). The output changes on the falling edge of TCK
and TDO is connected to the Least Significant Bit (LSB) of
any register.
is set LOW (VSS) when the BYPASS instruction is ex-
ecuted.
Boundary Scan Register
The boundary scan register is connected to all 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 x36 configuration has a 75-bit-long
register and the x18 configuration also has a 75-bit-long
register. 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 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.
PERFORMING A TAP RESET
A Reset is performed by forcing TMS HIGH (VDD) for five
rising edges of TCK. RESET may be performed while the
SRAM is operating and does not affect its operation. At
power-up, the TAP is internally reset to ensure that TDO
comes up in a high-Z state.
TAP REGISTERS
Registers are connected between the TDI and TDO pins
andallowdatatobescannedintoandoutoftheSRAMtest
circuitry. Only one register can be selected at a time
through the instruction registers. Data is serially loaded
intotheTDIpinontherisingedgeofTCKandoutputonthe
TDO pin on the falling edge of TCK.
TheBoundaryScanOrdertablesshowtheorderinwhichthe
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.
Scan Register Sizes
Instruction Register
Three-bit instructions can be serially loaded into the
instruction register. This register is loaded when it is
placed between the TDI andTDO pins. (See TAP Controller
Block Diagram) At 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 previously described.

BoundaryScan
When the TAP controller is in the CaptureIR state, the two
least significant bits are loaded with a binary “01” pattern
to allow for fault isolation of the board level serial test path.
Identification (ID) Register
Bypass Register
The ID register is loaded with a vendor-specific, 32-bit
code during the Capture-DR state when the IDCODE
commandisloadedtotheinstructionregister.TheIDCODE
is hardwired into the SRAM and can be shifted out when
the TAP controller is in the Shift-DR state. The ID register
has vendor code and other information described in the
Identification Register Definitions table.
To save time when serially shifting data through registers,
it is sometimes advantageous to skip certain states. The

TAP INSTRUCTION SET
SAMPLE/PRELOAD
Eight instructions are possible with the three-bit instruction
register and all combinations are listed in the Instruction
Code table. Three instructions are listed as RESERVED
and should not be used and the other five instructions are
described below. The TAP controller used in this SRAM is
not fully compliant with the 1149.1 convention because
some mandatory instructions are not fully implemented.
The TAP controller cannot be used to load address, data or
control signals and cannot preload the Input or Output
buffers. The SRAM does not implement the 1149.1 com-
mands EXTEST or INTEST or the PRELOAD portion of
SAMPLE/PRELOAD; instead it performs a capture of the
Inputs and Output ring when these instructions are executed.
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 from the instruction register through the TDI and
TDO pins. To execute an instruction once it is shifted in,
the TAP controller must be moved into the Update-IR
state.
SAMPLE/PRELOAD is a 1149.1 mandatory instruction.
The PRELOAD portion of this instruction is not imple-
mented, so the TAP controller is not fully 1149.1 compli-
ant. When the SAMPLE/PRELOAD instruction is loaded
to 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.
It is important to realize that the TAP controller clock
operates at a frequency up to 10 MHz, while the SRAM
clock runs more than an order of magnitude faster.
Because of the clock frequency differences, it is possible
that during the Capture-DR state, an input or output will
under-go a transition. The TAP may attempt a signal
capture while in transition (metastable state). The device
will not be harmed, but there is no guarantee of the value
that will be captured or repeatable results.
To guarantee that the boundary scan register will capture
the correct signal value, the SRAM signal must be
stabilized long enough to meet the TAP controller’s
capture set-up plus hold times (tCS and tCH). To insure that
the SRAM clock input is captured correctly, designs need
a way to stop (or slow) the clock during a SAMPLE/
PRELOAD instruction. If this is not an issue, it is possible
to capture all other signals and simply ignore the value of
the CLK captured in the boundary scan register.
EXTEST
EXTEST is a mandatory 1149.1 instruction which is to be
executed whenever the instruction register is loaded with
all 0s. Because EXTEST is not implemented in the TAP
controller, this device is not 1149.1 standard compliant.
The TAP controller recognizes an all-0 instruction. When
an EXTEST instruction is loaded into the instruction
register, the SRAM responds as if a SAMPLE/PRELOAD
instruction has been loaded. There is a difference between
the instructions, unlike the SAMPLE/PRELOAD instruction,
EXTEST places the SRAM outputs in a High-Z 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.
Note that since the PRELOAD part of the command is not
implemented,puttingtheTAPintotheUpdatetotheUpdate-DR
state while performing a SAMPLE/PRELOAD instruction
will have the same effect as the Pause-DR command.
IDCODE
BYPASS
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 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.
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.
RESERVED
These instructions are not implemented but are reserved
for future use. Do not use these instructions.
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. It also
places all SRAM outputs into a High-Z state.
