DESCRIPTION
The ISSI IS62/65WV2568DALL and IS62/65WV2568DBLL
are high-speed, 2M bit static RAMs organized as
256K 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 IS62/65WV2568DALL and IS62/65WV2568DBLL are
packaged in the JEDEC standard 32-pin TSOP (TYPE I),
sTSOP (TYPE I), and 36-pin mini BGA.

Note:
1. At f = fmax, address and data inputs are cycling at the maximum frequency, f = 0 means no input lines change.
2. Typical values are measured at Vcc = 3.0V, Ta = 25oC and not 100% tested.
