FEATURES

DESCRIPTION

The ISSI IS61C64B is a very high-speed, low power,

8192-wordby8-bitstaticRAM.ItisfabricatedusingISSI'shigh-

performance CMOS technology. This highly reliable process

coupled with innovative circuit design techniques, yields ac-

cess times as fast as 10 ns with low power consumption.

• High-speed access time: 10, 12, and 15 ns

• Automatic power-down when chip is

deselected

• CMOS low power operation

— 450 mW (typical) operating

— 250 µW (typical) standby

• TTL compatible interface levels

• Single 5V power supply

WhenCEisHIGH(deselected),thedeviceassumesastandby

mode at which the power dissipation can be reduced down to

250 µW (typical) with CMOS input levels.

EasymemoryexpansionisprovidedbyusingoneChipEnable

input, CE. The active LOW Write Enable (WE) controls both

writing and reading of the memory.

• Fully static operation: no clock or refresh

required

• Three state outputs

The IS61C64B is packaged in the JEDEC standard 28-pin,

300-mil SOJ, and TSOP.

• One Chip Enables (CE) for increased speed
