FEATURES

DESCRIPTION

The ISSI IS61C25616AL/AS and IS64C25616AL/AS are

high-speed,4,194,304-bitstaticRAMsorganizedas262,144

words by 16 bits. They are fabricated using ISSI's high-

performanceCMOStechnology.Thishighlyreliableprocess

coupled with innovative circuit design techniques, yields

access times as fast as 12 ns with low power consumption.

HIGH SPEED: (IS61/64C25616AL)

• High-speed access time: 10ns, 12 ns

• Low Active Power: 150 mW (typical)

• Low Standby Power: 10 mW (typical)

CMOS standby

LOW POWER: (IS61/64C25616AS)

• High-speed access time: 25 ns

• Low Active Power: 75 mW (typical)

When CE is HIGH (deselected), the device assumes a

standbymodeatwhichthepowerdissipationcanbereduced

down with CMOS input levels.

• Low Standby Power: 1 mW (typical)

CMOS standby

Easy memory expansion is provided by using Chip Enable

andOutputEnableinputs,CEandOE.TheactiveLOWWrite

Enable(WE)controlsbothwritingandreadingofthememory.

A data byte allows Upper Byte (UB) and Lower Byte (LB)

access.

• TTL compatible interface levels

• Single 5V 10ꢀ power supply

• Fully static operation: no clock or refresh

required

The IS61C25616AL/AS and IS64C25616AL/AS are pack-

agedintheJEDECstandard44-pin400-milSOJand44-pin

TSOP (Type II).

• Available in 44-pin SOJ package and

44-pin TSOP (Type II)

• Commercial, Industrial and Automotive tempera-

ture ranges available

• Lead-free available
