DESCRIPTION
The ISSI IS61LP6432A/36A is a high-speed synchronous
static RAM designed to provide a burstable, high-performance memory for high speed networking and communication applications. The IS61LP6432A is organized as 64K
words by 32 bits and the IS61LP6436A is organized as 64K
words by 36 bits. Fabricated with ISSI's advanced CMOS
technology, the device integrates a 2-bit burst counter, highspeed 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 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 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.
