DESCRIPTION

The

ISSI

IS61(64)LPS12832A, IS61(64)LPS/VP-

S12836A and IS61(64)LPS/VPS25618A are

high-speed,

low-power synchronous static

RAMs

designed to provide

burstable, high-performance memory for communication

and networking applications. The IS61(64)LPS12832A

organized as 131,072 words by 32 bits.

The IS61(64)LPS/

VPS12836A is organized as 131,072 words by 36 bits.

The IS61(64)LPS/VPS25618A

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.

The byte write operation is performed by using the 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 gener-

ated internally and controlled by the

ADV

(burst address

advance) input pin.

The mode pin is used to select the burst sequence or-

der, Linear burst is achieved when this pin is tied LOW.

Interleave burst is achieved when this pin is tied HIGH

or left floating.
