DESCRIPTION
The
ISSI
IS62WV51216ALL/ IS62WV51216BLL are high-
speed, 8M bit static RAMs organized as 512K 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 IS62WV51216ALL and IS62WV51216BLL are packaged
in the JEDEC standard 48-pin mini BGA (7.2mm x 8.7mm)
and 44-Pin TSOP (TYPE II).
