FEATURES
• High-speed access time: 70, 100, and 120 ns
• CMOS low power operation
– 120 mW (typical) operating
– 6
µW
(typical) CMOS standby
• TTL compatible interface levels
• Single 3V
±
10% V
CC
power supply
• Fully static operation: no clock or refresh
required
• Three state outputs
• Data control for upper and lower bytes
• Industrial temperature available
• Available in the 44-pin TSOP (Type II) and
48-pin mini BGA
The
ISSI
IS62LV12816L is a high-speed, 2,097,152-bit static
RAM organized as 131,072 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
CE
is HIGH (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,
CE
and
OE
. 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 IS62LV12816L is packaged in the JEDEC standard
44-pin TSOP (Type II) and 48-pin mini BGA.

of 0.4 to 2.2V and output loading specified in Figure 1.
2. Tested with the load in Figure 2. Transition is measured
±500
mV from steady-state voltage. Not 100% tested.
