DESCRIPTION

The ISSI IS62/65WV2568EALL/EBLL are high-speed,

2M bit static RAMs organized as 256K words by 8 bits.

It is fabricated using ISSI's high-performance CMOS

technology. This highly reliable process coupled with

innovative circuit design techniques, yields high-

performance and low power consumption devices.

When

is HIGH (deselected) or when CS2 is

LOW (deselected), the device assumes a standby

mode at which the power dissipation can be reduced

down with CMOS input levels.

Easy memory expansion is provided by using Chip

Enable and Output Enable inputs. The active LOW

Write Enable

controls both writing and reading

of the memory.

The IS62/65WV2568EALL/EBLL are packaged in the

JEDEC standard 32-pin TSOP (TYPE I), sTSOP

(TYPE I), and 36-pin mini BGA..
