FEATURES

DESCRIPTION

The ISSI IS61LV25616 is a high-speed, 4,194,304-bit static

RAM organized as 262,144 words by 16 bits. It is fabricated

using ISSI'shigh-performanceCMOStechnology. Thishighly

reliable process coupled with innovative circuit design tech-

niques, yields high-performance and low power consumption

devices.

• High-speed access time:

— 7, 8, 10, 12, and 15 ns

• CMOS low power operation

• Low stand-by power:

— Less than 5 mA (typ.) CMOS stand-by

• TTL compatible interface levels

• Single 3.3V power supply

WhenCEisHIGH(deselected),thedeviceassumesastandby

mode at which the power dissipation can be reduced down

with CMOS input levels.

• Fully static operation: no clock or refresh

required

Easy memory expansion is provided by using Chip Enable

and Output Enable inputs, CE and OE. The active LOW Write

Enable(WE)controlsbothwritingandreadingofthememory.A

databyteallowsUpperByte(UB)andLowerByte(LB)access.

• Three state outputs

• Data control for upper and lower bytes

• Industrial temperature available

The IS61LV25616 is packaged in the JEDEC standard

44-pin 400-mil SOJ, 44-pin TSOP Type II, 44-pin LQFP and

48-pin Mini BGA (8mm x 10mm).
