DESCRIPTION

FEATURES

The ISSI IS61LV25616L is a high-speed, 4,194,304-bit

static RAM organized as 262,144 words by 16 bits. It is

fabricated using ISSI's high-performance CMOS technol-

ogy. This highly reliable process coupled with innovative

circuitdesigntechniques,yieldshigh-performanceandlow

power consumption devices.

• High-speed access time:

— 10, 12, and 15 ns

• Low Active Power

— Less than 90mA (typ.) Active Current

• Low standby power:

— Less than 1 mA (typ.) CMOS standby

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

standby mode at which the power dissipation can be

reduced down with CMOS input levels.

• TTL compatible interface levels

• Single 3.3V power supply

• Fully static operation: no clock or refresh

required

Easy memory expansion is provided by using Chip Enable

and Output Enable inputs, CE and OE. The active LOW

Write Enable (WE) controls both writing and reading of the

memory.A data byte allows Upper Byte (UB) and Lower

Byte (LB) access.

• Three state outputs

• Data control for upper and lower bytes

• Industrial temperature available

The IS61LV25616L is packaged in the JEDEC standard

44-pin400-milSOJ,44-pinTSOPTypeII,44-pinLQFPand

48-pin Mini BGA (8mm x 10mm).
