DESCRIPTION
The ISSI IS66WV1M16EALL and IS66/67WV1M16EBLL are
high-speed,16M bit static RAMs organized as 1M 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.
FUNCTIONAL BLOCK DIAGRAM
The IS66WV1M16 EALL and IS66/67WV1M16EBLL are
packaged in the JEDEC standard 48-ball mini BGA
(6mm x 8mm). The device is also available for die sales.
