DESCRIPTION
The
ISSI
IS61/64WV3216BLL is a high-speed, 524,288-bit
static RAM organized as 32,768 words by 16 bits. It is
fabricated using
ISSI
's high-performance CMOS
technology. This highly reliable process coupled with inno-
vative circuit design techniques, yields access times as
fast as 12ns (3.3V + 10%) and 15ns (2.5V-3.6V) 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 IS61/64WV3216BLL is packaged in the JEDEC stan-
dard 44-pin TSOP-II, and 48-pin mini BGA (6mm x 8mm).
