DESCRIPTION
The IS62WV51216EALL/ IS62WV51216EBLL are
high-speed, 8M bit static RAMs organized as 512K
words by 16 bits. It is fabricated using '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 IS62WV51216EALL and IS62WV51216EBLL are
packaged in the JEDEC standard 48-pin mini BGA
(6mm x8mm), 44-Pin TSOP (TYPE II) and 48-pin
TSOP (TYPE l).
