FEATURES
DESCRIPTION
The 4Mb product family features high-speed, low-power
synchronous static RAMs designed to provide burstable,
high-performance memory for communication and
networking applications. The IS61(64)LPS/VPS12836EC are
organized as 131,072 words by 36bits. The
IS61(64)LPS/VPS12832EC are organized as 131,072 words by
32bits. The IS61(64)LPS/VPS25618EC are organized as
262,144 words by 18 bits. Fabricated with ISSI's advanced
CMOS technology, the device integrates a 2-bit burst
counter, high-speed SRAM core, and high-drive capability
outputs into a single monolithic circuit. All synchronous
inputs pass through registers controlled by a positive-
edge-triggered single clock input.
Internal self-timed write cycle
Individual Byte Write Control and Global Write
Clock controlled, registered address, data and
control
Burst sequence control using MODE input
Three chip enable option for simple depth
expansion and address pipelining
Common data inputs and data outputs
Auto Power-down during deselect
Single cycle deselect
Write cycles are internally self-timed and are initiated by
the rising edge of the clock input. Write cycles can be one
to four bytes wide as controlled by the write control inputs.
Snooze MODE for reduced-power standby
JEDEC 100-pin QFP, 165-ball BGA and 119-
ball BGA packages
Separate byte enables allow individual bytes to be written.
The byte write operation is performed by using the byte
write enable (/BWE) input combined with one or more
individual byte write signals (/BWx). In addition, Global
Write (/GW) is available for writing all bytes at one time,
regardless of the byte write controls.
Power supply:
LPS: VDD 3.3V (± 5%), VDDQ 3.3V/2.5V (± 5%)
VPS: VDD 2.5V (± 5%), VDDQ 2.5V (± 5%)
JTAG Boundary Scan for BGA packages
Industrial and Automotive temperature support
Lead-free available
Bursts can be initiated with either /ADSP (Address Status
Processor) or /ADSC (Address Status Cache Controller)
input pins. Subsequent burst addresses can be generated
internally and controlled by the /ADV (burst address
advance) input pin.
Error Detection and Error Correction
The mode pin is used to select the burst sequence order.
Linear burst is achieved when this pin is tied LOW.
Interleave burst is achieved when this pin is tied HIGH or
left floating.

NOTE:
1. X means “Don’t Care.” H means logic HIGH. L means logic LOW.
2. For WRITE, L means one or more byte write enable signals (/BWa-d) and /BWE are LOW or /GW is LOW. /WRITE = H for all /BWx, /BWE, /GW HIGH.
3. /BWa enables WRITEs to DQa’s and DQPa. /BWb enables WRITEs to DQb’s and DQPb. /BWc enables WRITEs to DQc’s and DQPc. /BWd enables
WRITEs to DQd’s and DQPd. DQPa and DQPb are available on the x18 version. DQPa-DQPd are available on the x36 version.
4. All inputs except /OE and ZZ must meet setup and hold times around the rising edge (LOW to HIGH) of CLK.
5. Wait states are inserted by suspending burst.
6. For a WRITE operation following a READ operation, /OE must be HIGH before the input data setup time and held HIGH during 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 always initiates an internal READ at the L-H edge of CLK. A WRITE is performed by setting one or more byte write enable signals and
/BWE LOW or /GW LOW for the subsequent L-H edge of CLK. See WRITE timing diagram for clarification.

ERROR DETECTION AND CORRECTION
Independent ECC with Hamming code for each byte.
Detect and correct one bit error per byte.
Better reliability than parity code schemes that could detect error bit but NOT correct it.
Backward compatible : Drop in replacement to current in industry standard devices without ECC.

1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
Exposure to absolute maximum rating conditions for extended periods may affect reliability.
2. This device contains circuitry to protect the inputs against damage due to high static voltages or electric fields; however, precautions may be taken to
avoid application of any voltage higher than maximum rated voltages to this high-impedance circuit.
3. This device contains circuitry that will ensure the output devices are in High-Z at power up.

IEEE 1149.1 TAP and Boundary Scan
The SRAM provides a limited set of JTAG functions to test the interconnection between SRAM I/Os and printed
circuit board traces or other components. There is no multiplexer in the path from I/O pins to the RAM core.
In conformance with IEEE Standard 1149.1, the SRAM contains a TAP controller, instruction register, boundary
scan register, bypass register, and ID register.
The TAP controller has a standard 16-state machine that resets internally on power-up. Therefore, a TRST signal
is not required
Disabling the JTAG feature
The SRAM can operate 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 left disconnected. They
may alternately be connected to VDD through a pull-up resistor. TDO should be left disconnected. On power-up,
the device will come up in a reset state, which will not interfere with device operation.
Test Access Port Signal List:
1. Test Clock (TCK)
This signal uses VDD as a power supply. 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.
2. Test Mode Select (TMS)
This signal uses VDD as a power supply. The TMS input is used to send commands to the TAP controller and is
sampled on the rising edge of TCK.
3. Test Data-In (TDI)
This signal uses VDD as a power supply. The TDI input is used to serially input test instructions and 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 connected to the most significant
bit (MSB) of any register. For more information regarding instruction register loading, please see the TAP
Controller State Diagram.
4. Test Data-Out (TDO)
This signal uses VDDQ as a power supply. The TDO output ball is used to serially clock test instructions and data
out from the registers. The TDO output driver is only active during the Shift-IR and Shift-DR TAP controller states.
In all other states, the TDO pin is in a High-Z state. The output changes on the falling edge of TCK. TDO is
connected to the least significant bit (LSB) of any register. For more information, please see the TAP Controller
State Diagram.

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 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 registers. Data is serially loaded
into the TDI pin on the rising edge of TCK and output on the TDO pin on the falling edge of TCK.
1. Instruction Register
This register is loaded during the update-IR state of the TAP controller. 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 described in the previous section. When the TAP controller is in the capture-IR state, the two LSBs
are loaded with a binary “01” pattern to allow for fault isolation of the board-level serial test data path.
2. Bypass Register
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 (VSS) when the BYPASS
instruction is executed.
3. Boundary Scan Register
The boundary scan register is connected to all the input and bidirectional balls on the SRAM. Several balls are
also included in the scan register to reserved balls. The boundary scan register is loaded with the contents of the
SRAM Input and Output 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. Each bit corresponds to one of the balls on
the SRAM package. The MSB of the register is connected to TDI, and the LSB is connected to TDO.
4. 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.

TAP Instruction Set
Many instructions are possible with an eight-bit instruction register and all valid combinations are listed in the TAP
Instruction Code Table. All other instruction codes that are not listed on this table are reserved and should not be
used. 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.
1. EXTEST
The EXTEST instruction allows circuitry external to the component package to be tested. Boundary-scan register
cells at output balls are used to apply a test vector, while those at input balls capture test results. Typically, the first
test vector to be applied using the EXTEST instruction will be shifted into the boundary scan register using the
PRELOAD instruction. Thus, during the update-IR state of EXTEST, the output driver is turned on, and the
PRELOAD data is driven onto the output balls. However, this product forces all SRAM outputs to High-Z state and
this instruction is not 1149.1 compliant.
2. 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. The IDCODE instruction is loaded into the instruction
register upon power-up or whenever the TAP controller is given a test logic reset state.
3. SAMPLE Z
If the SAMPLE-Z instruction is loaded in the instruction register, all SRAM outputs are forced to an inactive drive
state (high-Z), moving the TAP controller into the capture-DR state loads the data in the SRAMs input into the
boundary scan register, and the boundary scan register is connected between TDI and TDO when the TAP
controller is moved to the shift-DR state.
4. SAMPLE/PRELOAD
When the SAMPLE/PRELOAD instruction is loaded into the instruction register and the TAP controller is in the
capture-DR state, a snapshot of data on the inputs and bidirectional balls is captured in the boundary scan register.
The user must be aware that the TAP controller clock can only operate at a frequency up to 50 MHz, while the
SRAM clock operates significantly faster. Because there is a large difference between 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. 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. To ensure 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 time. 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. 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 balls.
6. 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 TDI and TDO. The advantage of the BYPASS instruction is that it shortens the
boundary scan path when multiple devices are connected together on a board.

Do not use these instructions. They are reserved for future use and engineering mode.

1. Places Qs in high-Z in order to sample all input data, regardless of other SRAM inputs.
2. TDI is sampled as an input to the first ID register to allow for the serial shift of the external TDI data.
3. BYPASS register is initiated to VSS when BYPASS instruction is invoked. The BYPASS register also holds the last serially loaded TDI when exiting the
shift-DR state.
4. SAMPLE instruction does not place Qs in high-Z.
5. This instruction is reserved. Invoking this instruction will cause improper SRAM functionality.
6.
This EXTEST is not IEEE 1149.1-compliant. By default, it places Q in high-Z. If the internal register on the scan chain is set high, Q will be updated with
information loaded via a previous SAMPLE instruction. The actual transfer occurs during the update IR state after EXTEST is loaded. The value of the
internal register can be changed during SAMPLE and EXTEST only.
