DESCRIPTION
The ISSI IS62WV5128ALL / IS62WV5128BLL 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 CS1 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 IS62WV5128ALL and IS62WV5128BLL are packaged
in the JEDEC standard 32-pin TSOP (TYPE I), 32-pin
sTSOP (TYPE I), 32-pin TSOP (Type II), 32-pin SOP and
36-pin mini BGA.
