IS62C256

32K x 8 LOW POWER CMOS STATIC RAM

FEATURES

DESCRIPTION

The ISSI IS62C256 is a low power, 32,768 word by 8-bit

CMOS static RAM. It is fabricated using ISSI's high-

performance, low power CMOS technology.

• Access time: 45, 70 ns

• Low active power: 200 mW (typical)

• Low standby power

WhenCSisHIGH(deselected),thedeviceassumesastandby

mode at which the power dissipation can be reduced down to

250 µW (typical) at CMOS input levels.

— 250 µW (typical) CMOS standby

— 28 mW (typical) TTL standby

• Fully static operation: no clock or refresh

required

Easy memory expansion is provided by using an active LOW

input. TheactiveLOWWriteEnable(WE)controlsbothwriting

and reading of the memory.

• TTL compatible inputs and outputs

• Single 5V power supply

The IS62C256 is pin compatible with other 32K x 8 SRAMs in

plastic SOP or TSOP (Type I) package.
