DESCRIPTION
The ISSI IS61LPS/VPS102436A and IS61LPS/VPS
204818A are high-speed, low-power synchronous static
RAMs designed to provide burstable, high-performance memory
for communication and networking applications. The
IS61LPS/VPS102436A is organized as 1,048,476 words
by 36 bits. The IS61LPS/VPS204818A is organized as
2M-word 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 positiveedge-triggered single clock input.
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.
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.
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.
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.

Q
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-h) 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-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.

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-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.

Notes:
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 circuity 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.

Notes:
1. All dimensioning and
tolerancing conforms to
ANSI Y14.5M-1982.
2. Dimensions D1 and E1 do
not include mold protrusions.
Allowable protrusion is 0.25
mm per side. D1 and E1 do
include mold mismatch and
are determined at datum
plane -H-.
3. Controlling dimension:
millimeters.
