FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION
The ISSI IS62WV1288ALL / IS62WV1288BLL are high-
speed, 1M bit static RAMs organized as 128K 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) 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.
The IS62WV1288ALL and IS62WV1288BLL are packaged
in the JEDEC standard 32-pin TSOP (TYPEI), sTSOP
(TYPEI), SOP, and 36-pin mini BGA.
