DESCRIPTION
The ISSI IS61(64)LF12832A, IS64VF12832A, IS61(64)
LF/VF12836A and IS61(64)LF/VF25618A are high-speed,
low-power synchronous static RAMs designed to provide
burstable, high-performance memory for communication
and networking applications. The IS61(64)LF12832A is
organized as 131,072 words by 32 bits. The IS61(64)LF/
VF12836A is organized as 131,072 words by 36 bits. The
IS61(64)LF/VF25618A is 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.
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.
Byte write operation is performed by using 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.

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.

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.
