DESCRIPTION

The

speed, 4M bit static RAMs organized as 512K words by 8

bits. It is fabricated using

technology. This highly reliable process coupled with

innovative circuit design techniques, yields high-

performance and low power consumption devices.

When CS1 is HIGH (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

(WE) controls both writing and reading of the memory.

The IS62WV5128ALL and IS62WV5128BLL are packaged

in the JEDEC standard 32-pin TSOP (TYPE I), 32-pin

sTSOP (TYPE I), 32-pin TSOP (Type II), and 36-pin mini

BGA.
