DESCRIPTION
The
ISSI IS62LV25616LL is high-speed, 4,194,304 bit
static RAM organized as 262,144 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
CEisHIGH(deselected)orwhenCEislowandbothLBand
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,
CEand OE.TheactiveLOWWriteEnable
(
WE)controlsbothwritingandreadingofthememory.Adatabyte
allows Upper Byte (
UB) and Lower Byte (LB) access.
The IS62LV25616LL is packaged in the JEDEC standard
44-pin TSOP (Type II) and 48-pin mini BGA (8mm x 10mm
and 7.2mm x 8.7mm).
