DESCRIPTION
The
ISSI
IS62WV2568ALL / IS62WV2568BLL 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) or when
CS1
is LOW, CS2 is HIGH, 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 IS62WV2568ALL and IS62WV2568BLL are packaged
in the JEDEC standard 32-pin TSOP (TYPE I), sTSOP
(TYPE I), and 36-pin mini BGA.

Notes:
1. Test conditions assume signal transition times of 5 ns or less, timing reference levels of 0.9V, input pulse levels of 0.4V to 1.4V
and output loading specified in Figure 1.
2. The internal write time is defined by the overlap of
CS1
LOW, CS2 HIGH and
WE
LOW. All signals must be in valid states to initiate a Write, but any one can go
inactive to terminate the Write. The Data Input Setup and Hold timing are referenced to the rising or falling edge of the signal that terminates the write.
3. Tested with the load in Figure 2. Transition is measured 500 mV from steady-state voltage. Not 100% tested.
