DESCRIPTION
The
ISSI
IS64LV25616AL 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
circuit design techniques, yields high-performance and low
power consumption devices.
When
CE
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,
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 IS64LV25616AL is packaged in the JEDEC standard
44-pin TSOP Type II and 48-pin Mini BGA (8mm x 10mm).
