DESCRIPTION
The ISSI IS62/65WV5128EALL/BLL/CLL are high-
speed, 4M bit static RAMs organized as 512K words by
8 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 CS# is HIGH (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.
The IS62/65WV5128EALL/EBLL are packaged in the
JEDEC standard 32-pin TSOP (TYPE I/II), sTSOP
(TYPE I), SOP and 36-pin mini BGA.
