FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION
The ISSI IS66WV51216EALL and IS66/67WV51216EBLL
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) 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 IS66WV51216EALL and IS66/67WV51216EBLL are
packaged in the JEDEC standard 48-ball mini BGA (6mm
x 8mm) and 44-Pin TSOP (TYPE II). The device is aslo
available for die sales.
