DESCRIPTION

FEATURES

The ISSI IS61LV256AL 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 process coupled with innovative circuit design

techniques, yields access times as fast as 8 ns maximum.

• High-speed access times:

— 10 ns

• Automatic power-down when chip is deselected

• CMOS low power operation

— 60 µW (typical) CMOS standby

— 65 mW (typical) operating

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

standbymodeatwhichthepowerdissipationisreducedto

150 µW (typical) with CMOS input levels.

• TTL compatible interface levels

• Single 3.3V power supply

Easy memory expansion is provided by using an active

LOW Chip Enable (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

• Lead-free available

The IS61LV256AL is available in the JEDEC standard 28-

pin,300-milSOJandthe450-milTSOP(TypeI)packages.
