FEATURES

DESCRIPTION

The ISSI IS62/65LV256AL 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 15 ns

maximum.

• High-speed access time: 20, 45 ns

• Automatic power-down when chip is deselected

• CMOS low power operation

— 17 µW (typical) CMOS standby

— 50 mW (typical) operating

• TTL compatible interface levels

• Single 3.3V power supply

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

standbymodeatwhichthepowerdissipationisreducedto

150 µW (typical) with CMOS input levels.

• Fully static operation: no clock or refresh

required

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.

• Three-state outputs

• Industrial and Automotive temperatures avail-

able

The IS62/65LV256AL is available in the JEDEC standard

28-pin SOJ, 28-pin SOP, and the 28-pin 450-mil TSOP

package.

• Lead-free available
