DESCRIPTION
The ISSI IS62/65WV12816EALL/EBLL are high-speed,
2M bit static RAMs organized as 128K 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 high-
performance and low power consumption devices.
When
is HIGH (deselected) or when CS2 is
LOW (deselected) or when
is LOW, CS2 is
HIGH and both
and
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. The active LOW
Write Enable
controls both writing and reading
of the memory. A data byte allows Upper Byte
and Lower Byte ( access.
The IS62/65WV12816EALL/EBLL are packaged in the
JEDEC standard 48-pin mini BGA (6mm x 8mm) and
44-Pin TSOP (TYPE II).
