DESCRIPTION
The
ISSI
IS62VV25616LL is a high-speed, 4,194,304 bit
static RAMs organized as 262,144 words by 16 bits. They
are 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.
For the IS62VV25616LL, when
CE
is HIGH (deselected)
or
CE
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,
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.
The IS62VV25616LL is packaged in the JEDEC standard
44-pin
TSOP
(Type II)
and
48-pin
mini BGA
(7.2mm x 8.7mm).
