DESCRIPTION
The ISSI IS64LP12832, IS64LP12836, and IS64LP25618
are high-speed synchronous static RAMs designed to
provide high-performance memory with burst for high-
speed networking and communication applications.
IS64LP12832 i s organized as 131,072 words by 32 bits.
IS64LP12836 is organized as 131,072 words by 36 bits.
IS64LP25618 is organized as 262,144 words by 18 bits. The
IS64LP12832, IS64LP12836, and IS64LP25618 are fabri-
cated with ISSI's advanced CMOS technology. These
devices integrate a 2-bit burst counter, high-speed SRAM
core, and high-drive capability outputs into a single mono-
lithic 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 from
one to four bytes wide as controlled by the write control
inputs.
Separate byte enables allow individual bytes to be written.
BW1 controls DQa, BW2 controls DQb, BW3 controls
DQc, BW4 controls DQd, conditioned by BWE being
LOW. A LOW on GW input would cause all bytes to be
written.
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.

Notes:
1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause perma-
nent 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.
