FEATURES

DESCRIPTION

The 36 Meg 'NLP/NVP' product family feature high-speed,

low-power synchronous static RAMs designed to provide

a burstable, high-performance, 'no wait' state, device for

networking and communications applications. They are

organizedas1Mwordsby36bitsand2M wordsby18bits,

fabricated with ISSI's advanced CMOS technology.

• 100 percent bus utilization

• No wait cycles between Read and Write

• Internal self-timed write cycle

• Individual Byte Write Control

• Single R/W (Read/Write) control pin

Incorporating a 'no wait' state feature, wait cycles are

eliminated when the bus switches from read to write, or

write to read. This device integrates a 2-bit burst counter,

high-speed SRAM core, and high-drive capability outputs

into a single monolithic circuit.

• Clock controlled, registered address,

data and control

• Interleaved or linear burst sequence control using

MODE input

Allsynchronousinputspassthroughregistersarecontrolled

byapositive-edge-triggeredsingleclockinput.Operations

may be suspended and all synchronous inputs ignored

when Clock Enable, CKE is HIGH. In this state the internal

device will hold their previous values.

• Three chip enables for simple depth expansion

and address pipelining

• Power Down mode

• Common data inputs and data outputs

• CKE pin to enable clock and suspend operation

All Read, Write and Deselect cycles are initiated by the

ADV input. When the ADV is HIGH the internal burst

counter is incremented. New external addresses can be

loaded when ADV is LOW.

• JEDEC 100-pin TQFP and 165-ball PBGA

packages

Write cycles are internally self-timed and are initiated by

the rising edge of the clock inputs and when WE is LOW.

Separate byte enables allow individual bytes to be written.

• Power supply:

NVP: V^DD2.5V ( 5ꢀ), VDDQ 2.5V ( 5ꢀ)

NLP: V^DD3.3V ( 5ꢀ), VDDQ 3.3V/2.5V ( 5ꢀ)

A burst mode pin (MODE) defines the order of the burst

sequence.WhentiedHIGH,theinterleavedburstsequence

is selected. When tied LOW, the linear burst sequence is

selected.

• Industrial temperature available

• Lead-free available
