DESCRIPTION
The
ISSI
IS61LV12816L is a high-speed, 2,097,152-bit
static RAM organized as 131,072 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 access times
as fast as 8 ns with low power consumption.
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 IS61LV12816L is packaged in the JEDEC standard
44-pin TSOP (Type II), 44-pin LQFP, and 48-pin mini BGA
(6mm x 8mm).
