DESCRIPTION
The ISSI IS62WV12816ALL/ IS62WV12816BLL are high-
speed, 2M bit static RAMs organized as 128K words by 16
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 and both
LB and UB are 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. A
data byte allows Upper Byte (UB) and Lower Byte (LB)
access.
The IS62WV12816ALL and IS62WV12816BLL are packaged
in the JEDEC standard 48-pin mini BGA (6mm x 8mm) and
44-Pin TSOP (TYPE II).

and output loading specified in Figure 1.
2.
The internal write time is defined by the overlap of CS1 LOW, CS2 HIGH and UB or LB, 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.
