DESCRIPTION

The

ICSI

IS61SP12832 is a high-speed, low-power synchro-

nous static RAM designed to provide a burstable, high-perfor-

mance, secondary cache for the PentiumTM, 680X0TM, and

PowerPCTM microprocessors. It is organized as 131,072

words by 32 bits, fabricated with

ICSI

'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 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

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

by the IS61SP12832 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:

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.
