DESCRIPTION

The ISSI IS61SP12832 and IS61SP12836 is a high-speed

synchronous static RAM designed to provide a burstable,

high-performance memory for high speed networking and

communication applications. It is organized as 131,072

words by 32 bits and 36 bits, fabricated with ISSI's ad-

vanced 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 syn-

chronous 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.
