DESCRIPTION
The
high-speed, 1M bit static RAMs organized as 128K words
by 8 bits. It is fabricated using
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 IS62/65WV1288BLL are
packaged in the JEDEC standard 32-pin TSOP (TYPEI),
sTSOP (TYPEI), SOP, and 36-pin mini BGA.
