128K x 16 LOW VOLTAGE,
ULTRA LOW POWER CMOS STATIC RAM
DESCRIPTION
FEATURES
The ISSI IS65WV12816ALL/ IS65WV12816BLL 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.
• High-speed access time: 55ns, 70ns
• CMOS low power operation:
36 mW (typical) operating
9 µW (typical) CMOS standby
• TTL compatible interface levels
• Single power supply:
When CS1 is HIGH (deselected) or when CS2 is LOW
(deselected) or when CS1 is LOW, CS2 is HIGH and both

1.65V to 2.2V Vdd (65WV12816ALL)
2.5V to 3.6V Vdd (65WV12816BLL)
• Fully static operation: no clock or refresh
Easymemory expansion is provided byusing 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.
