DESCRIPTION
The
ISSI
IS62WV25616ALL/IS62WV25616BLL are high-
speed, low power, 4M bit SRAMs organized as 256K words
by 16 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
CS1
is HIGH (deselected) or when
CS1
is LOW and
both
LB
and
UB
are HIGH, 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. A
data byte allows Upper Byte (
UB
) and Lower Byte (
LB
)
access.
The IS62WV25616ALL/IS62WV25616BLL are packaged n
the JEDEC standard 44-Pin TSOP (TYPE II) and 48-pin
mini BGA (6mmx8mm).
