DESCRIPTION
The ISSI IS62/65WV102416GALL/BLL are high-speed, low
power, 16M bit static RAMs organized as 1024K 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 CS1# is HIGH (deselected) or
when CS2 is LOW (deselected) or when CS1# is LOW,
CS2 is HIGH and both LB# and UB# 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
(WE#) controls both writing and reading of the memory.
A data byte allows Upper Byte (UB#) and Lower Byte (LB#)
access.
The device supports 16 I/Os when BYTE# is High, and 8
I/Os when BYTE# is Low. In x8 mode, UB#, LB#, and
I/O8~I/O14 are not used, and I/O15 becomes A20.
The IS62/65WV102416GALL/BLL are packaged in the
JEDEC standard 48-Pin TSOP (TYPE I)
.
