IS62LV2568LL
256K x 8 LOW POWER and LOW Vcc
CMOS STATIC RAM
ISSI
DESCRIPTION
The
ISSI
IS62LV2568LL is a low voltage, 262,144 words
by 8 bits, CMOS SRAM. It is fabricated using
ISS
I’s low
voltage, six transistor (6T),
CMOS technology.
The device
is
targeted
to satisfy the demands of the state-of-the-art
technologies such as cell phones and pagers.
When
CE
is HIGH (deselected), the device assumes a
standby mode at which the power dissipation
can be reduced
down with CMOS input levels. Additionally, 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.
The IS62LV2568LL is available in 32-pin TSOP (Type I),
STSOP (Type I), and 36-pin mini BGA.
