FEATURES

DESCRIPTION

The ISSI IS61LV256 is a very high-speed, low power,

32,768-word by 8-bit static RAM. It is fabricated using ISSI's

high-performance CMOS technology. This highly reliable pro-

cess coupled with innovative circuit design techniques, yields

access times as fast as 12 ns maximum.

• High-speed access time: 12, 15, 20, 25 ns

• Automatic power-down when chip is deselected

• CMOS low power operation

— 345 mW (max.) operating

— 7 mW (max.) CMOS standby

• TTL compatible interface levels

• Single 3.3V power supply

WhenCEisHIGH(deselected),thedeviceassumesastandby

mode at which the power dissipation is reduced to

50 µW (typical) with CMOS input levels.

• Fully static operation: no clock or refresh

required

Easy memory expansion is provided by using an active LOW

ChipEnable(CE).TheactiveLOWWriteEnable(WE)controls

both writing and reading of the memory.

• Three-state outputs

The IS61LV256 is available in the JEDEC standard 28-pin,

300-mil DIP and SOJ, plus the 450-mil TSOP package.
