The ISSI IS65WV25616ALL/IS65WV25616BLL are high-
speed, low power, 4M bit SRAMs organized as 256K 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 CS1 is low, 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 LOWWrite Enable (WE)
controls both writing and reading of the memory. A data byte
allows Upper Byte (UB) and Lower Byte (LB) access.
The IS65WV25616BALL/65WV25616BLL are packaged
in the JEDEC standard 44-Pin TSOP (TYPE II) and 48-pin
mini BGA (6mmx8mm).
